What is the current status of the ecological environment in western China?

Evaluation of the Basic Status Quo and Outstanding Problems of the Ecological Environment in the Western Region In the process of implementing the strategy for the development of the western region, protecting and gradually improving the ecological environment of the western region is of great importance to the development of the western region and the realization of sustained and healthy development of the western region. Carrying out surveys on the current state of the ecological environment, scientifically evaluating the current state of the ecological environment in the western region, and providing a basis for decision-making on the implementation of the strategy for the development of the western region is one of the important measures taken by the State Environmental Protection Administration to implement the strategy for the development of the western region. (1) The basic status quo of the ecological environment in the western region: 1. The natural environment is fragile and the ecological carrying capacity is relatively low.

The western region is vast, and 12 provinces, municipalities, and autonomous regions have been included in the scope of the country's large-scale development of the western region, and their land area exceeds that of the central and eastern regions combined. The climatic conditions in this region are significantly different, the geological conditions are variable, and the landform types are diverse. Northwest China is arid and rainless, and the degree of desertification is serious. The southwest mountain has a steep slope, shallow soil layer, and heavy rainfall; The Tibetan Plateau region is cold and harsh, and the air is thin.

The social and economic development of this region is relatively lagging behind, the ecological environment is fragile, and the ecological carrying capacity is low, making it the area with the worst ecological environment in the country. <>

The mountainous areas of western China are vast, with complex natural conditions, significant regional differences, deterioration of the agricultural environment, and weak economic foundation. Due to the lack of long-term people's understanding of ecological and environmental protection, the focus on short-term benefits and the sharpening of the contradiction between man and land, soil erosion, natural disasters, environmental pollution and land degradation in the western mountainous areas are more serious. The specific natural geographical environment and socio-economic conditions make it suitable for the development of agriculture in the mountainous areas of western China to take the road of ecological agriculture, adjust the industrial structure, and implement measures for soil and water protection and environmental pollution control, so as to restore and rebuild an agricultural ecological environment conducive to the sustainable development of agriculture in the mountainous areas of western China.

The most prominent ecological and environmental problems in the western region of China are soil erosion, land desertification, rocky desertification, grassland degradation, and frequent natural disasters.

Ecological and environmental problems and countermeasures in western China

The ecological environment in China's western region is fragile, and in recent years, due to some incorrect behaviors in the process of economic development, the ecological and environmental problems in the western region have become increasingly serious. ** The strategy for the large-scale development of the western region has been proposed, and a high degree of attention must be attached to the protection of the ecological environment in the course of the development of the western region.

At present, the reason for the deterioration of the ecological environment in the western region is not only the fragile ecological problem caused by the rising climate, but also the ineffective policy of encouraging population growth for a long time. In order to ensure that the large-scale development of the western region does not come at the expense of the environment, it is necessary to rely on effective intervention and correct guidance. Second, we must strengthen technological progress and change the mode of resource allocation, and in addition, we must firmly establish the concept of "sustainable development".

In the land resources of western China, the plain area accounts for 42%, the basin area is less than 10%, and about 48% of the land resources are deserts, Gobi, rocky mountains and alpine areas above 3,000 meters above sea level, and the annual average temperature is low, most provinces, autonomous regions and municipalities are below 10 degrees Celsius, and nearly half of the areas have annual precipitation below 200 mm.

The topography of western China falls from the roof of the world to the low-altitude plains, the climate is vertically distributed, the landform includes almost all types, and the animal and plant resources are rich and colorful.

The world-famous landscapes in western China include the Himalayas, the roof of the world, the sacred lake on the plateau, the Qiangtang Wildlife Park, the vast desert Gobi, the Loess Plateau with ravines, the vast pastures one after another, the majestic Qilian Glacier, the turbulent Jiuqu Yellow River, the karst landform that integrates the woods and rocks of the mountains, rivers, caves, forests and stones, and the beautiful and magnificent Three Gorges of the Yangtze River.

Most of the children have to walk a long way to go to school, and the learning conditions are poor, the burden of life is heavy, and the "hard-working baby" is still very difficult to study. The living environment on the barren land is a sad landscape.

The people who live in this barren land want to escape poverty, and the children raised on this land need a good education ......

Families here are often families with many children, or even families with eight children, and such families are more difficult than most people imagine, let alone in the barren and desolate Xihai Gushan Village. Children grow up eating pickles and yellow rice, and for them, eating steamed buns is the greatest joy, even though one bun has to be broken in half. Cherish the rare learning opportunity, grasp every minute of life, and the expression of concentration in the classroom is touching.

Most of the children in Xihaigu have almost no toys throughout their childhood. They don't have cars, they don't have submachine guns, they don't have pandas, and it doesn't seem to be a big pity, because at a young age, they have already made the mark of life, and they will participate in labor and housework earlier than anyone else. Rolling tires is also their greatest pleasure.

The children were very happy every time we handed out the donated clothes, even though many of the clothes were obviously so ill-fitting to them, as in this one.

The wind is blowing and the clouds are flying.

The closer you get to the west, the more you can feel this feeling.

The cost of living in the city is not high, the wages are not very high, and the development potential is high.

Look at the place. It's like that in big cities. Mountain villages are poorer.

Serious soil erosion, aggravation of land desertification, shortage of water resources, destruction of vegetation, and degradation of forests and grasslands are the main ecological and environmental problems faced by the western region, and industrial pollution has become the sequelae of urban economic development. All of these problems have their own problems: historically low levels of productivity and ecological fragility are mutually causal; The "overemphasis on food self-sufficiency" development model has led to deforestation and soil erosion; economic construction does not follow the laws of ecological environment, and the scientific and technological support capacity of ecological construction is weak; The system is fragmented, making it difficult to implement various measures for ecological environmental protection and construction.

As China's ecological barrier, the ecological environment of the western region has a bearing on the quality of life and development space of the entire nation, and is also a restrictive factor for the development of the western region, and the construction of the ecological environment has become a key issue for the survival and development of the people in the western region. Therefore, in the development of the western region, it is necessary to adhere to the dual principles of ecological construction and enriching the people and increasing income, so as to realize the organic unity of ecological and economic benefits in the large-scale development.

This is because the western region is an important ecological barrier in China, and it is also a "sensor" and an internal "sensitive area" for climate change in Asia and even the world. In recent years, China has increased its investment in the ecological environment of the western region, especially the protection of the ecological environment of the Qinghai-Tibet Plateau.

In 2005, China invested 7.5 billion yuan to launch the Sanjiangyuan Ecological Protection and Construction Project, which is the largest ecological protection project in China so far. Located in the hinterland of the Qinghai-Tibet Plateau, the source of the Yangtze River, the Yellow River and the Lancang River (Mekong River), the source area of the Three Rivers is known as the "Water Tower of China", an important ecological barrier and water conservation area in China and even Asia, and one of the most fragile and pristine areas of China's ecosystem.

In order to avoid taking the old road of "pollution first and then treatment" and to prevent soil desertification and serious environmental pollution, China has particularly emphasized environmental protection and economic development in the large-scale development of the western region in order to achieve sustainable economic development The development of soil and water conservation ecological agriculture to maintain and improve the ecological environment of the western region is in line with the strategy of sustainable development.

b. Controlling the excessive growth of the population cannot fundamentally solve the problem of water shortage and improve the living environment.

c. From the perspective of ecology and environment, prevention is more important than cure, and the water shortage in the western region is not caused by water pollution.

d. Solving the problem of pollution after economic development is the old road of "pollution first and then treatment", which is not in line with the theme of economic development, and D is wrong

Therefore, a

Answer: In order to avoid taking the old road of "polluting first and then rectifying" and to prevent soil desertification and serious environmental pollution, China has particularly emphasized environmental protection and economic development in the large-scale development of the western region, so as to achieve sustainable economic development. The development of ecological agriculture of soil and water conservation in order to maintain and improve the ecological environment in the western region is in line with the strategy of sustainable development.
