基于熵值法的土地资源可持续利用综合评价——以湖南省长沙市为例

Comprehensive Evaluation of Sustainable Utilization of Land Resources Based on Entropy Method—Taking Changsha City, Hunan Province as an Example

摘要: 随着城市化进程的加快，土地资源的可持续利用问题日益显著。为有效且准确评估土地资源的可持续利用性，本文以湖南省长沙市为例，采用熵值法从土地资源“经济可持续性”“社会可持续性”及“生态环境可持续性”三大维度进行评价，参考已有研究基础，共选取16个因子作为评价对象。研究结果表明：长沙市土地资源可持续利用在整体上呈现增长趋势；在2017~2022年间，经济可持续性和生态环境可持续性分别在2020年和2019年有所下降，但总体呈上升趋势；社会可持续性在2017~2019年间呈下降趋势，此后开始稳步上升；在2020年，长沙市土地资源由不可持续利用转为弱可持续利用，随后于2021年转为强可持续利用。针对研究结果，最后提出加强耕地保护、优化土地利用结构、提高土地利用效率等一系列相关建议，以期为长沙市土地资源的可持续利用提供借鉴。

Abstract: With the acceleration of the urbanization process, the problem of the sustainable utilization of land resources is becoming increasingly significant. For effective and accurate evaluation of the sustainable utilization of land resources, this paper takes Changsha city, Hunan province as an example, and uses the entropy method to evaluate from three dimensions of “economic sustainability”, “social sustainability”, and “ecological environment sustainability” of land resources. Referring to the existing research basis, a total of 16 factors are selected as the evaluation object. The results show that the sustainable utilization of land resources in Changsha showed an overall growth trend; from 2017 to 2022, economic sustainability and ecological environmental sustainability decreased in 2020 and 2019, respectively, but overall increased; the social sustainability decreased from 2017 to 2019 and then increased steadily; in 2020, land resources in Changsha changed from unsustainable utilization to weak sustainable utilization, and then to strong sustainable utilization in 2021. According to the research results, a series of relevant suggestions are put forward, such as strengthening cultivated land protection, optimizing land use structure and providing land use efficiency, in order to provide a reference for the sustainable utilization of land resources in Changsha.
