Optimization Of Land Use Patterns Of Underdeveloped Areas Based On The Development Priority Zones Planning A Case Study In Guizhou Province

The development priority zones planning divided regions into different types of main functional areas based on the carrying capacity of resources and environment, the exploitation strength and the development potential, which is consistent with objectives of "differentiated land use policy". Therefore, combining the theoretical framework of "the development priority zones planning", the region will develop more coordinated with land use and economical development. This article aims at solving the problem of optimizing land-use model in underdeveloped areas within the framework of the development priority zones planning. The main conclusions are as follows:Constructing the index system based on the concept of the development priority zones planning, by researching relationship of land use and regional economic in Guizhou using factor analysis, it could be found that a strong coupling relationship exists between land use and regional economic in Guizhou Province, and the different aspects of regional economic development are derived by different land-use factors while the economic factors also have an impact on land-use mechanism. In this paper, parts of conclusions of the coupling relationship consist with previous researches, Guizhou Province, spatial distribution of coupling degree of land use and regional economic compare with the spatial distribution of the the main functional areas of in the various regions of Guizhou Province, coming to the spatial layout of industrial land in Guizhou ProvinceIn the empirical study, respectively selecting focus, restricted and prohibited development zones that include the main features of urbanization, ecological and agricultural functions. Constructing the index system based on the concept of the development priority zones planning and natural, economic and social conditions of different geographical scales empirical zones, this article evaluates local land use land use patterns in different geographical scale empirical areas by respectively mathematical models of entropy method, artificial neural networks, analytic hierarchy process and multiple linear regressions, and eventually optimizes environment-friendly. The main empirical findings are as follows:(1)The overall level of economic development in Nanping City is higher than that in Bijie City. Land use structure is irrational, land use potential is small, and land carrying capacity is seriously overloaded in central urban of Nanping. It is concluded that land use pattern in Nanping is high-density centralized and Bijie’s is centralized, and land use function, spatial distribution and land using pattern is similar, and their land exploitation characteristics are different because of differences of their spatial location and natural social and economic conditions. Learning from the experiences and lessons of Nanping City development, when optimizing land use patterns, industrial and residential land function of the city center should be transferred to the sub-city centers of Gan Jaqiao, Hai Zijie and Ya Chi-Li Shu and so on where there are industries basis in Bijie.(2)According to land-use performance evaluation of counties in different main functional areas using BP artificial neural network, land-use patterns of city group is suitable for Qixingguan; land-use patterns of specialty agriculture is suitable for Dafang; land-use patterns of mountain forest&grass planting and breeding is suitable for Hezhang. It should be increased that the proportion of traffic, industry and mining, logistics and urban living and public facilities; It should be planted on a large scale that potatoes, peppers and other pollution-free vegetables and medicinal herbs such as Gastrodia in Dafang; It should increase the proportion of land of ecology, agriculture, forestry, animal husbandry, sideline production and public service area in Hezhang. The article also make recommendations for population and fiscal transfer payment of inter-empirical counties, At last, the industrial layout to the township as a unit under land use patterns of each empirical counties is demonstrated through ArcGIS software.(3)This article analyses the factors significantly influencing on the rural land circulation (land assets features) and agricultural management (features) in karst mountainous area demonstration village using the multivariate linear regression model. Based on the above analysis, the paper suggests that households can choose the ecological agriculture of "family farm business pattern" or "scale pattern" after improving irrigation and transport facilities, but proposals for agriculture industrialization combined with other industries such as tourism, which helps increasing income of households, and households can choose "hybrid business pattern" of agricultural production and non-agricultural business, but the best choice in the local operations or employment, does not promote households to distant cities to choose "off-farm employment pattern."According to analyzing theoretically and empirically coupling between land use and regional economy based on the concept of the development priority zones planning in Guizhou Province, this thesis evaluates land use in the cities, counties and villages of empirical areas, and proposes ways to optimize their land use patterns, at last proposes policy recommendations of differential land use policy for different main functional areas in the less developed regions.
