Study On The Classification Of Village Area And Its Development Path In The Three Gorges Reservoir Area

With the progress of new urbanization and industrialization in our country,the gap between urban and rural areas and regional differences is remarkable,and the problem of rural development has become increasingly prominent.The development of the village area of the Three Gorges reservoir area is restricted by the location and special geographical environment factors.The development level of the village is low,the development process is slow and the development contradiction is prominent,which has become the short board of regional coordinated development.In view of the fragile ecological environment of the Three Gorges reservoir area,especially in poverty-stricken areas where the rural development process is backward,carry out the rural development research,combined with the actual situation of the village,the key factors of the development of the village,tap the key development potential of the village,It is particularly important and urgent to explore a development path that conforms to regional characteristics and give full play to the endogenous power of rural areas and promote the sustainable and healthy development of villages.The study divided the village type into a certain administrative area,within a certain period of economic development,social development,ecological environment and other subsystems to form a certain combination of rural development and development of the state,the main performance For the agricultural development,economic growth,social progress,environmental improvement of the interaction process,and then based on a certain method of these characteristics of the classification results.On the basis of this,through combing the relevant theoretical basis and research results of the research on the development of villages and villages at home and abroad,we take the random sampling survey and interview method,the spatial analysis method,the penalty variable method and the cluster analysis method.Research methods,collection and processing of the Three Gorges reservoir area 65 administrative villages of the basic data and data,respectively,the village ecological environment sensitivity,economic development index,social development index to calculate.And constructs the three-dimensional coordinate system which is the interaction between the village economic development,the social development and the ecological environment based on the combination and development of the interaction between economy,society and ecology.The classification and the result of the village type,analyze the development ideas and direction of the village in different scenarios,and explore the path and decision of the village development under the premise of ecological security in the Three Gorges reservoir area.The main contents and conclusions are as follows:(1)To carry out the Three Gorges reservoir area village ecological environment sensitivity evaluation research.Considering the results of previous studies and the actual situation of the Three Gorges reservoir area,five indicators of rainfall erosion,average elevation,slope grade,soil texture and vegetation coverage were selected to evaluate the sensitivity of soil erosion in the Three Gorges reservoir area.Lithology,vegetation cover type and land use type were used to evaluate the sensitivity of rockland desertification in the Three Gorges reservoir area,and the ecological sensitivity index of the village area was measured from both soil erosion and rocky desertification.The index of the ecological environment reflects the size of the ecological environment,and the ecological environment sensitivity is the important foundation of the village area division and development path selection in the Three Gorges reservoir area.(2)Design the weight correction method based on variable weight theory,measure the village economic development index and social development index respectively.From the rural economic index,rural production index two aspects of the per capita net income of farmers,planting industry accounted for the proportion of agricultural output value of eight indicators,to build the village economic development index evaluation index system,calculate the village economic development index;from the rural facilities index And the rural life index in two aspects of the choice of traffic degree,the proportion of brick and concrete structure of the seven indicators,to build the village social development index evaluation index system,calculate the village social development index.Combined with the economic development and social development index,to carry out the Three Gorges reservoir area classification and development path selection.(3)On the basis of the systematic relationship between economy,society and ecology,the three-dimensional coordinate system formed by the interaction between economic development,social development and ecological environment is constructed.According to the system of village economy Social,ecological three sub-systems between the different combinations and development status of the classification of village types.According to the type structure of "combination mode + development state",the study area is divided into "economic-social-ecological" high-quality coordination and high-level,"economic-social-ecological" "Local ahead of the lower type," economic-social-ecological "backward all low-level and other four categories.According to the difference and significance of the combination,the "economic-social-ecological" partial lag is further subdivided into "economic-social-ecological" economic development lagging higher,"economic-social-ecological" society The economic and social-ecological ecological environment is lagging behind and so on.The economic-social-ecological partial development is further subdivided into "economic-social-ecological" economic development Ahead of the lower type,"economic-social-ecological" social development ahead of the lower type,"economic-social-ecological" ecological environment ahead of the lower three kinds of small type.(4)Combining the division method and the division result of the village area of the Three Gorges reservoir area,the village development is placed in the three-dimensional system of economic,social and ecological interaction,and it is regarded as a progress from low level to advanced state The development process of change.The paper analyzes the operation mechanism of the three-dimensional coordinate system of the village system,analyzes the future development direction of different village areas,and further explores the development path of different village types.(5)In the aspect of village road development,the "economic-social-ecological" high-quality coordination of high-level,need to maintain from the low level of coordinated development to a high degree of coordinated development of this highly efficient development trend."Economic-social-ecological" local lagging higher,one is to improve the economic development and social development process does not match the situation;the second is to explore the ecological environment fragile sensitive factors and sensitivity to identify the ecological sensitive sources and timely Measures to improve and protect."Economy-society-ecology" partial advance lower type,one is to pay special attention to the ecological environment ahead of economic development and social development ahead of the two combinations of state and characteristics;the second is in the village ecological security under the premise of moderate development or restricted development."Economic-social-ecological" backward low equilibrium,should consider restricting the development or prohibit the development,increase the fragile ecological environment of the protection.
