基于SEM和GIS的人居环境自然适宜性评价的一种方法
A New Evaluation Methodology of the Natural Suitability ty for Human Settlements Based on SEM and GIS
摘要
Abstract
In view of the defects in the traditional evaluation models of natural suitability for human settlements, forexampe, the models mostly focus on the macro impact factors on human settlements, they can only deal with single variable, and cannot tolerate any measurement errors of both the dependent and independent variables, they also cannot take into account the structure and relations among factors at the same time, the index weight is seriously affected by the subjective factors, etc. The paper proposed to introduce the structural equation to the evaluation model of natural suitability for human settlements, quantitatively studied the weight of each influential factor in the evaluation model as well as the interaction among various factors, then combined the evaluation model with GIS to visualize the evaluation process and results, which provided references for relevant studies.关键词
