Study On The Spatial Optimization Of Rural Residential Land Based On Resident Population Perspective

Land is the basic prerequisite for all the human production and life.The rural residential land is an indispensable part of land use.Also it is the core of human and natural environment.In the process of urban and rural transformation,the resident population in rural areas are reducing gradually,however the per capita residential areas are rising,and village-hollowing numbers are increasing.These phenomenon lead to more land resources wasted.Based on this fact,the paper choose Ningwu county in Shanxi province as an example,by using GIS spatial analysis and social survey methods,to analyze the spatial optimization of rural residential land from the resident population perspective.This paper is of great significance to improve the rural living environment,speed up the new urbanization and new rural construction and protect the land resources.(1)The distribution of rural residential land and population are closely related to terrain and location factors.In terms of terrain,the rural settlements and population are markedly affected by the altitude,slope and aspect of the terrain.As the altitude and slope increases,the distribution of the rural residential land and population gradually decreases,the resident population will show a more apparent drop.Influenced by the aspect of the slope,the rural residential land and population are mainly distributed in the light side to east and south rather than in the dark side to west and north.In term of location,the distribution of rural residential land and population have a strong relationship with the distance towards main roads,rivers and township centers.The distribution of rural settlements and population decreases with the increase of distance,among which the township center will pose a strong influence on the resident population than roads and rivers.(2)The measure of rural residential land consolidation potentiality will be more scientific if based on resident population.The consolidation potentiality is an important social factor influencing the layout of rural settlements,which is the basis and prerequisite for the optimization of optimizing the layout of rural settlements.Based on the resident population we can obtain a consolidation potentiality,the coefficient of which can divide the rural residential land into high,medium,low,and no potential four parts.(3)The evaluation system of rural residential areas layout optimization will be established in the consideration of nature,society and location.Through nine indicators on these three aspects,with a use of entropy method,the rural residential areas are divided into four levels in terms of suitability,that is highly livable,moderately livable,less livable and inhospitable.(4)Based on the evaluation of layout optimization,the optimization model of rural residential layout is established.The combination of suitability classification with the actual survey results,the four types of layouts are determined as the model of rural residential layout optimization.The city village should continue to strengthen economic development in the future,while using the land planning,predicting the population and land size;the center village should increase economic development channels through industry transformation and upgrading;the reserved village,in the long run,should gradually move to the central village and city village;the immigration village should accelerate its improvement pace by way of some specific immigration projects.In conclusion,the layout optimization of rural residential areas in the basis of resident population will provide a new direction and analysis framework for the residential areas' arrangement and planning.It is necessary to carry out research in different ways from different perspectives.
