Study On Site Selection And Optimization Of Poverty Alleviation In Mountainous Areas

Relocation of the land for poverty alleviation is a powerful starting point for implementing precise poverty alleviation and precision poverty alleviation,and is a key measure for building a well-off society in an all-round way.However,in the actual relocation work,different reasons have caused problems in the site selection,scale,and spatial layout of the relocation and resettlement sites.Although the state and local governments have made relevant regulations on site selection,scale,and type of housing for relocation and resettlement sites,such as the ―Technical Essentials of Planning for Relocation and Resettlement of Relocation in Guizhou Province‖,the site selection for resettlement sites for poverty alleviation The principled opinion: "The location of centralized resettlement settlements should be based on county-level rural construction planning research and township residential layout planning,and follow the requirements of safety,development,economy,convenience,and ecology.Science Determine the location of the site and the scale of the resettlement." Such normative documents have a certain normative role in the process of relocation and poverty alleviation.However,these guiding principles do not quantify the indicators and are insufficiently instructive and targeted in practical work.Especially for the mountainous areas with steep slopes and complex topography,there is no comprehensive guidance.This paper takes Qiongbei Mountainous Area-Xinzhan Town,Tongzi County,Zunyi City,Guizhou Province as the research object,and applies the theory of location theory,agricultural location theory,landscape ecology theory,human-land coordination theory and other theories on the basis of relevant research at home and abroad.In the mountainous area,the GIS technology is used to analyze the village system and land use in the study area,and the landscape index method is introduced to quantitatively describe its distribution characteristics.Secondly,the distribution of residential areas and current resettlement sites in the study area is classified and analyzed.Points and resettlement points are affected by different impact factors in the study area,and the relevant parameters are obtained by sampling survey method.From the perspective of residents’ living conditions,the overall construction effectiveness of the resettlement sites is comprehensively evaluated.On this basis,combined with the characteristics of the mountainous areas in northern Fujian and the goal of relocation and poverty alleviation,from the four basic indicators of topography,location,resources and ecological conditions,15 secondary indicator factors such as elevation,slope,aspect,water source and road are selected to construct the resettlement.Point location index system.Then the index system is applied to the study area based on the relevant data of the study area,and the research results are divided into four categories: most suitable,suitable,low and suitable.Finally,according to the results of the resettlement construction effectiveness evaluation and site selection,combined with the future ex situ poverty alleviation and relocation plan of the research area,the resettlement sites will be optimized from the aspects of village and town system,resettlement site scale,land use and spatial layout of resettlement sites.The optimized resettlement site is closer to the service facility;the resettlement site is more reasonable;the land use at the resettlement site is more intensive.
