中文摘要	中国西南地区碳酸盐岩出露广泛，土壤和植被是其岩溶生境中最为敏感的自然要素。综述了西南岩溶区的土壤形成与演化、植被生态特征与演替等方面的研究进展，探讨了岩溶区生态脆弱性的评价理论，指出岩溶生态重建关键问题和进一步需要研究的主要内容。最后，对西南岩溶生态恢复与重建对策进行了探讨。
英文摘要	Karst environment is distributed largely in Southwest China. Soil and vegetation are the most sensitive elements to the variation of Karst environment. The weathering of carbonate is important soil formation mechanism in Karst areas, but its soil forming ability is so poor that soil layer thickness becomes thin by the water erosion, though the soil loss is insignificant but serious. The character of Karst plants is firmly connected with the environment condition, i.e., lack of water, richness of Ca~(2+), poor soil and shortage of organic matter, the plants have low pace growth and low life-form resource, and is vulnerable under the disturbance of irrational human activities. Therefore, the rocky desertification is the end of Karst ecosystem degradation, but these degradation processes are depended on different land use patterns. Further, this paper discusses the assessment of the fragility on Karst ecosystem and raises vital problems on how to improve productivity. Finally, this paper suggests some solutions about rehabilitation of ecology to solve the problems of man-land relation in Karst environment in Southwest China.
