Influence of Wanzhou Three Gorges Immigrants on Wanzhou

(1) blindly developing industry may aggravate the environmental pollution in the reservoir area; Affect (reduce) the water quality in the reservoir area; Reduce the quality of human settlements (industrial land may also destroy vegetation and cause soil erosion) (4 points). The mountain slope is large, and the expansion of planting will cause serious soil erosion, aggravate sediment deposition in the reservoir area, shorten the service life of the Three Gorges Reservoir (reduce the channel traffic conditions in the reservoir area); With the expansion of planting, the application of pesticides and fertilizers will produce serious non-point source pollution, which will affect the water quality of the reservoir area and even the whole Yangtze River. (water conservation capacity is reduced, groundwater is reduced, etc. ) (4 points)

(2) It is conducive to strengthening the economic ties between the main city and the cities along the line and Wanzhou; Improve the investment environment in Wanzhou and attract more enterprises to invest in Wanzhou; It is conducive to the transfer of science and technology, capital, information, management experience and other elements in the main city to Wanzhou, and accelerate the industrial development and upgrading of Wanzhou; Promote Wanzhou to accelerate the process of urbanization; Creating more employment opportunities for immigrants in the reservoir area is conducive to the stability of the reservoir area; It is conducive to the transfer of local population from the primary industry to the secondary and tertiary industries and the absorption of rural surplus labor; Improve the overall level of social and economic development in Wanzhou. (8 points, only 4 of them will be answered, and other reasonable answers will be given extra points as appropriate)

(3) Developing biogas and using manure as biogas raw material (solving the problem of manure pollution); Biogas can provide clean living energy for pig farms; Biogas residue can be used as fertilizer for citrus; Using biogas residue as fertilizer to develop feed crops (such as vegetables and corn) and provide feed for pig farms; Develop animal products processing industry, extend industrial chain, expand industry and increase income. (6 points, only 3 points should be reasonable).

Figure (4 points, in which there must be biogas, focusing on the development of related industries, as long as there are four reasonable elements)

Test analysis:

(1) "Most ecological conservation areas in northeast Chongqing are mountainous areas, and most cities are located along the Yangtze River". If the industry is blindly developed, the industrial "three wastes" will pollute the environment, especially the wastewater entering the Yangtze River, which will affect the water quality in the Three Gorges reservoir area and lead to the deterioration of the water quality in the reservoir area; Blind industrial expansion may lead to the destruction of vegetation, and soil erosion is prone to occur in mountainous areas. If the planting industry is blindly expanded, deforestation and grass planting on sloping land in mountainous areas will cause serious soil erosion, aggravate sediment deposition in the reservoir area and affect the use and navigation of the reservoir. A large number of pesticides and fertilizers used in aquaculture will pollute the water quality of the Yangtze River and lead to the deterioration of the ecological environment in the ecological conservation area of the Three Gorges reservoir area.

(2) The significance of railway line construction is mainly analyzed from promoting local social and economic development. It is conducive to strengthening the economic ties between the main city and the cities along the line and Wanzhou; Improve the investment environment in Wanzhou and attract more enterprises to invest in Wanzhou; It is conducive to the transfer of science and technology, capital, information, management experience and other elements in the main city to Wanzhou, and accelerate the industrial development and upgrading of Wanzhou; Promote Wanzhou to accelerate the process of urbanization; Creating more employment opportunities for immigrants in the reservoir area is conducive to the stability of the reservoir area; It is conducive to the transfer of local population from the primary industry to the secondary and tertiary industries and the absorption of rural surplus labor; Improve the overall level of social and economic development in Wanzhou.

(3) As shown in the following figure, biogas digesters can be introduced, and feces can be used as fertilizer for citrus fields and raw materials for biogas digesters; Biogas solves the energy consumption problem of farmers' production and life; Biogas residue can be used as fertilizer for citrus planting, and straw in citrus field can be used as raw material for biogas digesters and feed for pig farms. This not only solves the problem of environmental pollution caused by feces, but also reduces the production cost of farmers, thus increasing economic benefits and realizing the coordination and unity of ecological benefits, economic benefits and social benefits.
