基于灰色关联分析的城市土地可持续利用综合评价——以湖南省为例

文章从资源节约、环境友好、经济发展和社会和谐四方面构建城市土地可持续利用评价指标体系，采用灰色关联分析方法从时间和空间两个维度对湖南省城市土地可持续利用水平进行综合评价。认为湖南省城市土地可持续利用水平逐年提高，但仍有较大提升空间；各地级市中长沙城市土地可持续利用水平最高，邵阳最低，各城市土地可持续利用水平差异显著。因此，湖南应进一步加快经济发展速度，提高城市内涵，以可持续发展理论为指导，积极改进城市土地利用中的不足。

Evaluation of Urban Land Sustainable Use Based on Grey Related Analysis Theory

This paper analyzes the content of sustainable urban land use, builds the evaluation system of sustainable urban land use from four aspects of resource-saving, environment friendly, economic development and social harmony. A grey related analysis model is used to evaluate urban land sustainable use from the two dimensions of time and space. The research shows that the level of sustainable urban land use in Hunan Province has increased annually, but there is still much room for improvement ; Changsha is the highest level of sustainable urban land use, Shaoyang is the lowest level, and the sustainable urban land use is significantly different in 13 cities. To improve the level of sustainable urban land use, Hunan should further accelerate the pace of economic development, tap the potential of urban land use. Urban land use should be guided by the sustainable development theory, and the cities should actively improve the insufficiency of urban land use.
