基于熵权法的团风县土地资源利用可持续性评价

Evaluation of Sustainability of Land Resources Use of Tuanfeng County Based on Entropy Weight Method

基于团风县2013~2017年面源数据,构建资源环境、经济环境和社会环境3个维度14个指标构建评价体系,运用熵权法对该地区的土地可持续利用情况进行综合评价。结果表明:团风县土地可持续利用在资源环境、经济环境、社会环境3个方面的发展程度不平衡,2013~2017年该县资源环境指标的贡献率持续减低,经济环境指标的贡献率稳步提升,社会环境的贡献率基本保持不变;团风县土地可持续利用的综合分值由2013年的0.306 7增长至2017年的0.668 8,从土地可持续利用起步阶段已经进入发展阶段的中期水平,仍有提升空间。

Based on the non-point source data of Tuanfeng County from 2013 to 2017,14 indexes were selected from resources environment, economic environment and social environment to construct the evaluation system,and the entropy weight method was used to analyze the sustainable land use. The results showed that the degree of development of resources environment,economic environment and social environment was unbalanced.The contribution rate of resources environment indexes from 2013 to 2017 reduced continuously,while that of economic environment indexes steadily improved,and that of social environment basically unchanged. The composite score of sustainable land use increased from 0.306 7(2013) to 0.668 8(2017),the sustainable land use had been in the medium-term of development,and there was still room for improvement.
