| 针对三峡库区蓄水前后土地利用结构紊乱、城市发展与生态保护矛盾突显的问题，提出通过土地利用系统健康评价来有效引导土地合理利用，提升土地资源长期效益;从土地利用系统健康基本内涵出发，构建基于三角模型的评价指标体系对库区重庆段进行实证分析；结果表明：2000—2017年三峡库区（重庆段）土地利用系统健康状态不断提高，整体变化过程为“不健康-亚健康-初级健康”；系统健康状态的空间特征整体表现为渝西及渝东南高于渝东北；健康状态的变化趋势整体良好，主要以初级健康（T1、T3）的变化趋势为主；研究结果可反映本区域土地利用系统健康状态的发展态势，实现土地利用系统内部良性运行。 |

| In view of the problems of disordered land use structure before and after water storage in the Three Gorges Reservoir area and the contradiction between urban development and ecological protection, this paper proposes to guide the rational use of land effectively and promote the sustainable development of regional land resources through the health evaluation of land use system. Based on the analysis of the health connotation of the land use system, a triangular model based evaluation index system is constructed to make an empirical analysis of the Chongqing section of the reservoir area. The results showed that from 2000 to 2017, the health status of the land use system in the Three Gorges Reservoir area (Chongqing section)was continuously improved, and the whole land use system experienced the evolution process of "unhealthy, sub healthy and primary health",the overall spatial characteristics of health state showed that western Chongqing and southeast Chongqing were better than northeast Chongqing,the change trend of health status is generally good, mainly in primary health (T1, T3). The research results can reflect the development trend of the healthy state of the land use system in the region and realize the benign operation of the land use system. |
