摘要
Karst ecosystem is an ecosystem constrained by karst environment. A series of unique characteristics of karst ecosystem are originated from carbonate rock. In China, the area with karst landform covers a total area of 3.44 million km^2, accounting for one third of the whole land area of the country. The bare karst terrain covers an area of 907 000 km^2, which mainly distributed in southern of China, with Guizhou Province as the center, and about 40% of the poverty-stricken people live there. During the period of the l lth-Five-Year Plan （2006-2010） and the 12th Five- Year Plan （2011-2015）, the national program of ＂Integrated Control of Rocky Desertification in Karst＂ has been implemented in this region.
喀斯特生态系统是喀斯特环境约束的生态系统。喀斯特生态系统的一系列独特的特征，都源于碳酸盐岩。在中国，喀斯特地貌区面积3440000平方公里，面积2平方公里，占全国国土面积的三分之一。裸喀斯特地形占地000平方公里907平方公里，主要分布在中国南部，以贵州省为中心，约有40%的贫困人口居住在那里。第十一个五年计划期间（2006-2010年）和第十二个五年计划（2011-2015年），对“喀斯特”的石漠化综合治理国家的方案已在该地区实施的。
