宁夏开发区土地集约利用空间相关性及障碍度分析研究

Analysis on Spatial Correlation and Obstacle of Land Intensive Use in Ningxia Development Zone

以2017年为评价时间、宁夏整合优化后的22家开发区为研究对象,选取10项评价指标,应用多因素综合评价法对开发区进行土地集约利用定量评价.在此基础上,引入探索性空间分析方法和障碍度分析模型,研究宁夏开发区土地集约利用的空间自相关性和影响开发区土地集约利用的主要障碍度因素.结果表明,宁夏开发区土地集约利用以一般集约为主,呈现明显的全局空间正相关性和局部空间集聚特征;影响开发区土地集约利用的障碍度因素主要有工业用地率、建筑密度、工业用地综合容积率、工业用地固定资产投资强度和工业用地税收5项指标.

Taking the year of 2017 as the evaluation time and 22 development zones after integration and optimization in Ningxia as the research object,the article selected 10 evaluation indicators to quantitatively evaluate the land intensive use in the development zone with multi-factor comprehensive evaluation method.On this basis,it introduced the exploratory spatial analysis method and the obstacle analysis model to study the spatial autocorrelation of land intensive use in Ningxia development zone and the main obstacle factors affecting the intensive use of land in the development zone.The results show that the land intensive use in Ningxia development zone is mainly general intensive,showing obvious global spatial positive correlation and local spatial agglomeration characteristics;5 main obstacle factors affecting the intensive use of land in the development zone are industrial land use rate,building density,comprehensive plot ratio of industrial land,investment intensity of fixed assets of industrial land and industrial land tax.
