Researches On Functional Division Of Land Use In The Hilly Areas Of Northern Villages

The functional zoning of land use plays an important role in forming a reasonable pattern of land development and utilization and promoting the sustainable development of the regional socio-economic environment.From the perspective of ecological carrying capacity,carrying out functional zoning of land use has practical implications for the comprehensive analysis of regional realities and for the coordinated development of man and land.This paper aims at the impact of coal mining on the coal mining in the hilly areas of northern China's villages.The regional ecological carrying capacity is not high,and the sustainable use of land resources is increasingly serious,Take Zezhou County of Jincheng City,Shanxi Province as an example to analyze and evaluate the ecological carrying capacity of the study area and its development and changes,and carry out empirical research on land use function partitioning.The main research contents of the paper are:(1)This paper summarizes and sums up related research theories and techniques related to ecological carrying capacity and land use function zoning both at home and abroad,and establishes the foothold and ideas for this study.(2)Analysis the size of the ecological carrying capacity of the study area and its development and changes,and evaluate it from the three aspects of ecological elasticity,supporting capacity of the carrying media,and pressure of bearing objects.(3)A divisional index system was constructed using each township as a divisional unit,and a system cluster analysis method was used to determine the division of land use function in the study area.(4)Combining with the assessment of the ecological carrying capacity of the study area,relevant suggestions on future land use direction and land development and utilization patterns in various land use functional areas are proposed.The main conclusions of the paper are as follows:(1)In the period from 2007 to 2012,the ecological carrying capacity index of Zezhou County showed a steady upward trend,with the comprehensive index rising from 0.725 to 0.968,indicating that the ecological carrying capacity of Zezhou County is continuously improving.Among them,the eco-elasticity index fluctuates between 0.965 and 0.999 and is generally stable;The support index of the supporting media continued to increase.The index rose from 0.637 to 0.991,indicating that the carrying index of the ecosystem is getting higher and higher;The pressure index of the bearing objects fluctuates greatly,showing a trend of falling first,then rising and then falling.(2)Through constructing a land use function zoning index system,the principal components of the 15 indicators were analyzed and the three functional areas of the production function area,life function area,and ecological function area were finalized by combining related planning data.(3)Based on the assessment results of the ecological carrying capacity of the study area and the land use functional zoning program,the related suggestions for the development direction of land use in the three major function areas were proposed.The research results of the thesis have some reference and reference significance for the coordinated development of the region.
