How to apply geographic information technology in the study of regional geographical environment

As a regional discipline, the main foundation of cartography is geoscience. All of these field surveys and surveys in regional disciplines such as geography, geology, biology, and environmental science are inseparable from maps. The objects of cartography are also the objects of study of cartography.

Geographic information system.

Meaning: Also known as resource and environmental information system, geographic data system, spatial information system, land information system, etc., it is through the support of computer hardware and software, the comprehensive use of information science and system engineering theory, the analysis, synthesis and scientific management of geographic data with spatial connotation, so as to serve the technology in the fields of geographic decision-making, planning, research and research.

Basic characteristics: It can carry out spatial analysis, comprehensively analyze a variety of information, analyze the relationship between spatial entities, and deal with various processes and phenomena in the region. Geographic information systems (GIS) are particularly adept at processing spatial information.

Geographic information systems (GIS) contain various functions for processing geographic information. Among them, the most basic functions are: data collection, management, processing, analysis and output.

Relying on these basic functions, GIS deduces a variety of system application functions through the use of spatial analysis technology, model analysis technology, network technology, database and data integration technology, secondary development technology, etc., to meet the wide needs of society.

The application functions of GIS include land management, population geography and other aspects.

1) Human-environment relationship: Human-environment relationship has always been one of the traditions of geographical research, which refers to the interaction and mutual influence between human society and geographical environment. The geographical environment is the material basis and prerequisite for human beings to survive, develop and carry out all social production activities. Human beings can understand the geographical environment in the objectively existing natural things, and then use and transform the natural environment to make it better serve human production.

No matter what time in history, the study of geography has never detached Huaishan from the ** of people and land. The relationship between man and land has always been the most traditional subject of geography. The ultimate purpose of studying geography is to use geographical knowledge to better serve human society, and at the same time ensure that the changes in the geographical environment within the tolerance range are sustainable.

Therefore, the optimal coordination of human-land relationship is the core problem of geography.

2) Region: The relationship between man and land is the core of geographical research, but it is not the exclusive characteristic of geography. Geography is ultimately the study of the "principle" of "land", which is based on the distribution, development, evolution and law of geographical elements in the earth's surface.

Geographers should start from a regional perspective, focus on the local differences in the relationship between man and land under different ranges and scales on the surface, investigate the reasons, and then plan the regulation and control according to the regional characteristics.

Regionality is one of the most basic characteristics of geography, and the differences between different regions lead to differences in the relationship between people and land between regions, which is unique to geography from other disciplines. It is precisely because of this characteristic that geography can stand on the differences in different regions and different scales to gain an in-depth understanding of the production potential of different regions and inform the appropriate development direction, so as to provide a better theoretical reference for decision-making.

3) Systematic: Geography studies the phenomenon and law of spatio-temporal differentiation of geographical elements in different regions, including physical geographic elements and human geographic elements. Whether in time or space, the state of these elements is not static, it is always in a process of change but continuous interaction between elements.

The interaction between elements is not a linear relationship of simple superposition, but an open dynamic system formed by complex coupling coherent interaction, which is an organic whole with overall functions.

The main application areas of GIS include:

1. Environmental protection and management: mainly use GIS to establish environmental models and environmental information systems. 2. Social Survey and Statistical Analysis: Extensive use of wheel chains in population, election, and human geography.

3. Urban infrastructure management refers to the management of urban underground pipelines (such as pipes such as tap water, sewage discharge, and gas), communication networks, postal outlets, roads and transportation facilities.

4. Establishment of land information system: The land information system established based on GIS includes graphic processing ruler, spatial analysis and statistics, attribute information storage and query, and statistical report formation. Materials supplemented:

1. Geographic Information System (GIS) is sometimes referred to as:"Geoscience Information System", which is a very important spatial information system. It is a technical system that collects, stores, manages, calculates, analyzes, displays and describes the relevant geographical distribution data in the entire or part of the earth's surface (including the atmosphere) space under the support of computer hardware and software systems.

2. Geographic information system is a comprehensive discipline, which combines geography and cartography, remote sensing and computer science, and has been widely used in different fields. The system is also a computer system used to input, store, query, analyze, and display geographic data, and is also called GIS with the development of GIS"Geographic Information Science.

Geographic Information System (GIS) has a wide range of applications in many fields. Here are six common areas:

1.Urban planning: GIS can help urban planners analyze land use, population distribution, transportation networks, and environmental issues. They can use maps and spatial analysis tools to assess the feasibility of different planning options and optimize urban infrastructure and resource management.

2.Natural Resource Management: GIS plays an important role in natural resource management.

It can be used to monitor the health of forests, water and soils and help develop sustainable resource management strategies. In addition, GIS can be used to study and protect endangered species, manage nature reserves, and monitor natural disasters.

3.Agriculture and Rural Development: GIS can help farmers and rural development planners optimize cropland management, land use, and irrigation systems.

By analyzing soil quality, climate data, and crop growth models, farmers can develop optimal crop planting and management strategies to improve the yield and quality of agricultural products.

4.Health management: GIS can be used to analyze disease transmission patterns, outbreaks, and assess the distribution of healthcare resources.

It can help policymakers develop measures to combat the spread of disease, optimize the allocation of medical resources, and provide the public with information about health risks and medical services.

5.Market Analysis: GIS can help companies analyze market demand and competition, and optimize sales areas and network layouts.

By combining sales data, demographics, and geographic information, businesses can determine the best market positioning strategy to increase market share and profitability.

6.Environmental protection: GIS can be used to monitor environmental pollution, land degradation and water resource management.

It can help environmental agencies assess environmental impacts, formulate environmental protection policies, and plan environmental protection projects. GIS can also be used to monitor climate change, assess renewable energy potential, and promote sustainable development.

These areas are just a few of the applications of GIS, and it also plays an important role in many other areas, such as transportation planning, emergency management, and infrastructure construction. By combining geographic data with other data, GIS provides a deep understanding of spatial information that helps decision-makers make more informed decisions and provide better management and protection for our society and environment.

He has unique spatial analysis capabilities and is able to conduct in-depth technical research on space problems.

Diversification of information, a variety of geographic information acquisition methods, access to a variety of spatial data.

A wide range of applications.

The information is used and updated quickly.

Geographic information science was proposed by Goodchild in 1992, compared with geographic information system, it focuses more on geographic information as a science, not just a technical implementation, mainly studying a series of basic problems raised in the process of processing, storing, extracting, managing and analyzing geographic information in the application of computer technology, including: 1) distributed computing 2) cognition of geographic information 3) interoperability of geographic information 4) scale 5) the future of spatial information infrastructure 6) Uncertainty and GIS-based analysis of geographic data 7) GIS and society 9) Spatial analysis of GIS in the environment 10) Acquisition and integration of spatial data, etc. Geographic information science not only focuses on the research of geographic information technology, but also points out the importance of basic theoretical research that supports the development of geographic information technology. With the development of remote sensing, global positioning system and other technologies with geographic information system technology as the core and their mutual penetration, the 3S integrated technology system has gradually been formed, which provides new analytical methods and technical guarantees for solving modern geoscience problems with wider regional scope and higher complexity.

Since the 70s, due to the problems of population, resources, environment and development faced by the whole human society, the research on global change and sustainable development has gradually begun to be emphasized, and the promotion of these two aspects has finally led to the emergence of geo-information science. Geo-information science studies the material flow, energy flow and movement state and mode of movement within the earth system by means of information flow, it is composed of three parts, "geoinformatics" is the main body of its theoretical research, "geoinformation technology" is its research means, and "global change and regional sustainable development" is its main application field.
