基于熵权法和TOPSIS模型的龙口市建设用地集约利用评价

Evaluation of Construction Land Intensive Use Based on Entropy Weight Method and TOPSIS Model of Longkou City

摘要: 进行建设用地集约利用评价，对挖掘建设用地潜力、提高集约利用水平有重要意义。论文以山东省龙口市为研究区，构建包括用地投入、用地产出、增长耗地、用地弹性4个方面、12个指标的评价指标体系，基于熵权法和TOPSIS模型，评价2007~2016年建设用地集约利用水平。结果表明，2007~2016年，龙口市建设用地投入指数呈“下降–上升”趋势，用地产出指数持续提高，增长耗地指数整体呈“下降–波动上升”态势，用地弹性指数呈现“下降–波动上升”趋势，综合指数整体呈“缓慢下降–缓慢上升”趋势。提出严控建设用地总规模，加强村庄闲置宅基地整治等提高建设用地集约利用建议。

Abstract: The evaluation of construction land intensive use is of great significance to tapping the potential of construction land and improving the level of construction land intensive use. Taking Longkou City as the research area, this paper selected 12 indicators to establish the evaluation index system, which included land input, land output, land increasing consumption and land use elasticity aspects, and by the aid of entropy weight method and TOPSIS model evaluated the status and changes of construction land intensive use from 2007 to 2016. The results showed that the input level of construction land experienced process from declining to rising, the output level of construction land showed an overall growth trend, the level of land increasing consumption experienced process from declining to fluctuant rising, the level of land use elasticity experienced process from rapidly declining to fluctuant rising, and the comprehensive level of construction land intensive use of Longkou city had a downside from 2007 to 2011, and showed a slowly rising trend from 2012 to 2016. Lastly, some suggestions were given about construction land intensive use according to the researching results, such as strictly controlling the total scale of construction land, strengthening the management of rural idle homestead and carrying out remediation of village land to improve the intensity of village land use.
