喀斯特地区退化植被生态系统修复技术初探

Study on repair technology of degraded vegetation ecosystems in Karst regions

喀斯特岩溶地区是我国典型的生态脆弱区之一。森林植被生态系统是喀斯特地区防治石漠化、水土流失、涵养水源的最重要屏障,但其自身生产力、生物质保有量明显低于同纬度森林生态系统,稳定性较差,易受到干扰破坏而发生退化。在深刻理解退化生态系统内涵的基础上,分析了喀斯特森林植被生态系统退化的一般特征,并对典型退化森林植被生态系统修复技术进行了总结概括。

Karst region is an typical ecological fragile in Karst areas of southwestern China. Forest ecosystem is the most important barrier to control desertification, soil erosion, and addition water conservation in the Karst region, but its own productivity, biological quality and significantly lower than the same latitude forest ecosystem and stability is poor, vulnerable to interference and sabotagedegradation. On the basis of a deep understanding of the meaning of degraded ecosystems, the general features of the Karst forest ecosystem degradation, and the typical degraded forest ecosystem restoration techniques were summaried.
