摘　　要：从能值分析的角度,构建了赤水市水土保持生态修复工程项目区土地生态经济系统的能值指标,并对该区实施生态修复工程前后土地支撑能力的变化进行分析评价,得出项目区生态经济系统的土地支撑能力降低的幅度明显减少。项目区经过人为辅助措施和自身协调、恢复功能,其土地支撑能力在逐步回升和提高。From the perspective of energy analysis,the article analyses the changes of land sustaining capacity after this region implement,the ecosystem recovery project. The result indicates the declined scope of the land carrying capacity has reduced obviously.Through the artificial measure and their coordinating and restoring function of the area, land carrying capacity is rising and enhancing gradually.
