| 摘 要： | 以西南喀斯特地区为例,通过总结前人的研究成就和采集中国科学院亚热带农业生态研究所喀斯特生态实验站部分收集整理和试验数据,系统分析了喀斯特脆弱生态系统及其退化的机理,从"人-自然-经济复合生态系统"的观点出发,以干扰程度、群落类型、服务功能、土地退化和贫困状况为指标,创新性地提出了喀斯特脆弱生态系统的复合退化模式(含4个阶段),运用现代生态恢复学原理、方法和现代管理学创新理论,建立了喀斯特脆弱生态系统复合退化的控制模型.以此为基础,在喀斯特石山区、半石山区和土山丘陵区3个区域环境尺度范围内,针对性地建立了生态保护型、外向经济型和双三重螺旋3种生态恢复与重建模式,以促进喀斯特区域生态、经济、社会的全面协调与可持续发展. |

| Abstract: | The Karst area located at the center of Guizhou Tableland in China is the largest world. The typical problems in this region are poor ecological environment and poverty, where hardly to be recovered or restored; it is one of the six most vulnerable ecosystems in China. karst ecosystem is a complex process which was characterized by intensive human activities vegetation as inducement acting on the fragile continuous Karst zone in the the degraded ecosystems are Degradation of the vulnerable as driving force and decreasing geological resources, as a consequence, land deteriorated and desert landscape appeared. In this study, a new model was established to simulate the complex degradation process of vulnerable karst ecosystem based on local human activities, natural environment and economic development by using degrees, community types, service and function of ecosystems, land degradation and poverty as indicators. interruption The model showed that there were four major stages dominating the complex degradation process which were vegetation decreasing, loss of service and function of ecosystem, degeneration of soil quality and rocky desertification. The processes of degradation and restoration of vulnerable karst ecosystem did not occur simultaneously, and there were no linear relationships between them and restoration process took much longer time and was more difficult. A controlling model was also established to prevent rocky desertification using the principles and methods of temporary restoration ecology and temporary management. Based on this model, 3 types of recovering and restoration patterns of ecological protection, open economic and bi-triple helix were set up according to rocky mountain area, semi-rocky mountain area and mountain and hilly region, respectively, which would be greatly helpful to boost the harmonious and sustainable development of ecology, economy and society in Karst areas. |
