基于熵值法的建设用地集约利用评价研究——以新疆伽师县为例

Appraisal on Construction Land Intensive Use Based on Entropy Method——Taking Jiashi County of Xinjiang as an Example

基于熵值法评价伽师县建设用地集约利用水平,采用极值法对原始数据进行标准化处理,利用熵值法对建设用地投入、产出、利用强度三个方面八项指标赋权,借助多因素综合评价和协调度模型探究伽师县建设用地集约利用综合指数动态变化以及各项子系统土地集约状况。结果表明:2015年伽师县建设用地总集约度仅为0.4624,为"不太集约"状态,其中最制约因素为建设用地产出效率低;在2008~2015年期间,伽师县建设用地集约利用综合指数偏低且波动性强,但上升年份多余下降年份,可以尝试从促进优势资源的转化升级,探索科学的地方土地管理人才培养、引入机制,着重农村居民点的整治、规划入手,推动建设用地利用向着健康、集约的方向发展。

Evaluation of intensive utilization level of construction land in Jiashi County was based on entropy method.The extreme data method was used to standardize the original data.The entropy method was used to empower the eight indicators of the three aspects of construction land input,output and utilization intensity.With the help of multi-factor comprehensive evaluation and coordination degree model,the dynamic change of comprehensive index of intensive land was used in Jiashi County and the land intensive condition of various subsystems were explored.The results showed that,the total construction land in Jiashi County was only about 0.4624,which was a‘less intensive’state in the year of 2015.The most restrictive factor was the low efficiency of construction land output.During the years of 2008-2015,the comprehensive index of the intensive use of construction land in Jiashi County was low and the fluctuation was strong,but the surplus year of the rising was going up.We should try to promote the transformation and upgrade of superior resources,explore a scientific mechanism for training and introducing local land management personnel,and focus on the renovation and planning of rural residential areas to promote the healthy and intensive development of construction land use.
