Analyze the relationship between physical geography and urban planning

The physical geographical environment is an organic whole, in which various phenomena and processes are not isolated and accidental, but interrelated and mutually restrictive, that is, what we call the integrity of physical geography. And our so-called "pulling a whole body" is the best embodiment of wholeness, once one link changes, all other links will inevitably change. The consequence of the destructive transformation of the natural geographical environment by human beings is the deterioration of the natural geographical environment and endangers our own interests.

Especially in the cities where human beings live, due to the excessive development and transformation of human beings, the natural geographical environment of the city and its surroundings has been destroyed, resulting in a large number of environmental problems.

In order to coordinate this problem, we should start from the integrity of the natural geographical environment, and in the process of urban development and construction, we must always put the natural geographical environment in the first place, and exchange the development of other aspects at the minimum environmental cost, after all, the natural environment.

The time required for restoration after destruction is extremely long, and people are also an integral part of the natural environment, so all development must be based on the harmony between man and land.

The relationship between the natural geographical environment and urban planning is close, which is manifested in the following aspects:

1.Physical geography is one of the important considerations in urban planning. In the process of urban planning, it is necessary to fully consider the local natural geographical environment, including topography, climate, hydrology, vegetation, animals, soil and other factors.

These factors will not only affect the location and layout of the city, but also the function and economic development of the city.

2.The physical geography has an impact on the spatial layout and land use of the city. For example, in areas with large undulating terrain, the urban spatial layout will be more compact and the land use will be more diversified.

Climate, hydrology and other factors will also affect the spatial layout and land use of cities.

3.The natural geographical environment has an impact on the transportation, energy, and water resources of the city. For example, urban transportation needs to consider local topography, climate and other factors, and the use of energy and water resources also needs to consider the characteristics of the local natural geographical environment.

4.The natural geographical environment has an impact on the ecological environment and sustainable development of the city. In urban planning, it is necessary to fully consider the local natural geographical environment, protect the ecological environment, and promote sustainable development.

In short, the natural geographical environment is one of the important considerations in urban planning, which has an impact on the spatial layout, land use, transportation, energy, water resources, and ecological environment of the city. In urban planning, it is necessary to fully consider the local natural geographical environment, protect the ecological environment, and promote sustainable development.

If the natural geographical environment is good, then the development of the city will definitely have a future.

The differences in the physical geographical environment are as follows:

The difference is manifested in the fact that the geographical environment is composed of various elements (topography, climate, water, organisms, soil, etc.) with different properties: each element does not exist in a single form but in multiple forms; The geography is a regular combination of various morphological units of different sizes.

Differences: The two most basic characteristics of the physical geography are wholeness and difference. Regional differences refer to the fact that the global terrestrial environment is a unified whole, and its different regions show extremely significant regionality.

The natural geographical environment is composed of elements such as atmosphere, water, rocks, organisms, soil, and topography, and the components of the natural geographical environment interact with each other and affect each other. The elements of the terrestrial environment are interconnected, mutually restrictive and interpenetrating, constituting the integrity of the geographical environment.

Different regions on land form different climate types due to their different latitudes, sea and land locations, and different water and heat combinations, and different climate types form corresponding vegetation types and soil types. The corresponding climate, vegetation and soil together form a natural land zone with a certain width and distribution in a belt.

The regional differentiation of the terrestrial environment has obvious regularity: the regional differentiation law from the equatorial poles, the regional differentiation law from the coast to the interior, and the vertical regional differentiation law of the mountainous region. Manifestations of differences in physical geography:

Global regional differentiation: temperature differentiation, sea and land differentiation. Regional Geographical Differentiation:

Regional differentiation of terrestrial environment and marine environment. The main natural factors of land are latitude location, sea and land location, topography, climate type, vegetation type, soil type, etc.

Most of the early formation of cities was near rivers, which shows the importance of water to cities.

The establishment and evolution of the city can be said to be based on the geographical environment, the formation of the city in the early stage of a water source, and then began the evolution of resource-based cities is also based on the natural geography, resource-based cities need land resources, timber, minerals, etc., resources are the foundation of urban survival and development.

Later, the city began to develop towards the location of convenient transportation, with the flow of human beings in the section of Jiaohe Jing, the place with convenient transportation is more suitable for living, at this time the natural geography of the river intersection Zen Yuhui, the port area, the road intersection open location has become the first choice of the city.

At present, the relationship between socio-economic cities and the natural environment is mainly reflected in the geographical location, climate and transportation of the city.

Needless to say, the new tourist cities are all developed by relying on the geographical environment.

On the other hand, the development plan of a city must first consider the geographical environment, climate, wind direction, rock formation, water source, vegetation, and all aspects are inseparable from the geographical environment. The formation and evolution of cities are changed in response to human needs for the environment.

1.The impact of urbanization on the scattered bridges of the natural geographical environment Large-scale urban construction has changed the original natural environment and brought great changes to the original ecological environment. It is easy to cause geological disasters such as soil erosion, landslides, and debris flows.

The original nature of the underlying surface has been changed, resulting in a heat island effect in the city, and it has also affected the natural environment of the surrounding area to varying degrees. The urban wind formed brings urban air pollutants to the suburbs, and can also bring pollutants from the suburbs to urban areas. The process of urban construction destroyed the original river network system.

It is easy to make the city drain poorly during heavy rains, resulting in water on the ground, and the remaining river channels are also easy to turn black and smelly due to eutrophication. The pollution of production and life in the city, especially the "three wastes" of industry, interferes with and destroys the environmental ecology of the area. This makes the city's ecosystem very fragile.

2.The impact of urbanization on the human geographical environment has changed the way of land use, and the original agricultural land has been converted into construction land, and urban functional zoning has been formed. The employment form of residents has been changed, and regional industrial activities are dominated by non-agricultural dry digging and cultivation activities.

The densely populated urban landscape replaces the original rural landscape. The process of urbanization has led to the decentralization of population and industrial activities, while at the same time economic development and information exchange have been greatly enhanced. It has promoted the extensive penetration of modern civilization into traditional culture, and strengthened the cultural exchange and integration between the local and the outside world.

The difference of the natural geographical environment is manifested in the fact that the geographical environment is composed of various elements (topography, climate, water, biology, soil, etc.) with different properties; Each element does not exist in a single form, but in many; The geography is a regular combination of various morphological units of different sizes. The difference of the natural geographical environment is manifested in the fact that the geographical environment is composed of various elements (topography, climate, water, biology, soil, etc.) with different properties; Each element does not exist in a single form, but in many; The geography is a regular combination of various morphological units of different sizes. On the whole, the global geographical environment is a unified whole, but different regions of the whole often show extremely significant regional differences, and regional differences are common in the geographical environment.

Regional differences refer to the fact that the global terrestrial circumference is a unified whole, and its different regions show extremely significant regionality, and the exchange of matter and energy between geographical elements is carried out. The interaction between geographical elements generates new functions; The natural geographical environment has a unified evolutionary process. Regional differences refer to the fact that the global terrestrial ring is a unified whole, and its different regions show extremely significant regionality, and there is an exchange of matter and energy between geographical elements. The interaction between geographical elements generates new functions; The natural geographical environment has a unified evolutionary process.

Understand the physical geography.

The wholeness of copying can be started from the following two aspects: First, the various elements that make up the physical geographical environment are not isolated from each other, but develop and change as part of the whole. Each element forms the structural characteristics of the natural geographical environment through a special network relationship, and as a reflection of the organic connection of the system, each element subsystem is subordinate to the natural environment system itself, and each element is coordinated in its characteristics and unified with the overall characteristics.

Second, the integrity of the physical geographical environment is expressed through the movement of matter, energy and information within the system, and the change of one natural element will inevitably lead to the change of other elements and even the overall environmental state. For example, deforestation and planting trees and grasses will have different impacts on the natural geographical environment.

The totality of the physical geographical environment is relative, but the difference is absolute. On the one hand, it is impossible to find two areas with exactly the same natural condition; On the other hand, no matter how small an area is, there are still differences within it. Therefore, the area can be divided step by step.

Because the distribution of various natural elements has a certain regularity, the natural geographical environment formed by their joint action also has a certain regularity in regional differentiation. The law of regional differentiation is the basis and basis for studying the natural phenomena in a specific region and the utilization and transformation of the natural environment, and it is an ideal model based on ideal conditions.

The integrity of the geographical environment refers to the internal connection between the components of the geographical environment and the components. They are interconnected and mutually conditional, thus forming a whole, where one element influences the other, and one part influences the other. For example, the low-lying areas near the equator have the most solar heat, forming a high-temperature and rainy climate, thus creating favorable conditions for the growth of tropical plants; The variety of plants and abundant fruits provide sufficient food for a wide variety of animals**.

This intrinsic connection between the elements that make up the geographical environment constitutes the integrity of the geographical environment of the equatorial lowlands. For example, there are obvious differences in the geographical environment of the same latitude on the east and west sides of the Andes Mountains in South America, and this whole is due to the important role played by the Andean element.

Zonality mainly refers to the natural belt on land, which extends along the latitude in a certain width and changes in the north-south direction. The cause of zonal differences is mainly due to the fact that the earth is an ellipsoid, and the uneven distribution of solar radiation on the earth's surface produces a heat band distributed along the zonal direction. The zonality of heat distribution affects the distribution of water, and the different heat and water conditions of each zone form different climatic characteristics.

Under the influence of the pressure and wind zones on the earth, the climate is also distributed according to the zones. Climate affects plants, and plants are closely related to animals, so different climatic zones have different plant zones and corresponding animal kingdoms. In this way, a series of natural belts are formed on the whole continent that are distributed in the latitudinal direction, alternate from north to south, and various geographical elements are interconnected.
