Evaluation of Ecological Carrying Capacity of Land Resources in Hubei Province
摘要
Abstract
Taking Hubei Province as the research object,using the comprehensive index method to comprehensively consider the factors that were closely related to the study of regional land resources.Based on the PSR model,the regional evaluation index system was constructed from three aspects of pressure,state and response,and principal component analysis to determine the index weight.The evaluation results of the ecological environment carrying capacity of land resources in the study area were obtained by GIS technology.Based on the statistical analysis method,the average carrying capacity of land resources ecological environment was calculated,and the ecological carrying capacity of land resources in the area was divided into three types-low bearing capacity area,general bearing capacity area and high bearing capacity.Finally,the spatial pattern of the ecological carrying capacity of land resources in Hubei Province was analyzed.The results showed that:The spatial distribution of the carrying capacity of land resources in Hubei Province is low in the middle and west and high in the east.High carrying capacity area is located in the mountainous area;the general carrying capacity area is located in the northwest,southwest and northeast;low carrying capacity area is located in the central plains region.关键词
