摘　　要：对中国西南喀斯特退化生态系统的恢复和评价,是实现"人—自然—经济复合生态系统"可持续发展的重要基础。为此,首先分析了生态系统演化特点和生态系统"结构—过程—功能"的一体化,在此基础上提出人为驱动生态系统恢复的一种新途径。即通过丰富系统要素,加强各要素与多元化生态过程的耦合,驱动退化生态系统的自调控等内在机能的恢复,最终促使生态系统回复到自维持的动态平衡。其次,以喀斯特脆弱生态系统的退化特点和影响恢复的主导因子为基础,结合喀斯特退化生态系统恢复的特殊性,初步筛选出指示生态恢复的4类要素共11项指标,可用于对喀斯特退化生态系统的恢复评价和管理。In karst region of southwestern China, the restoration and evaluation of degraded ecosystems provide an important foundation for achieving sustainable development of ＂human-nature-economy＂ compound ecosystem. Therefore, based on the analysis of ecosystem evolution and its structure-process-function integration, this study first proposes that restoring economy by man as a new approach. That is, we can promote ecosystem returning dynamic balance of self- maintenance through enriching system elements, strengthening coupling between different elements and diversified ecology process as well as actuating restoration of the internal functions, such as self-regulation of degraded ecosystems and so on. Then, it screens out 4 elements and 11 indexes that indicate ecological restoration which can be used for evaluation and management of degraded ecosystem restoration in the karst region on the basis of characteristics of fragile ecosystem degradation, major factors affecting restoration and its specificity in karst areas.
