中文摘要	西南岩溶区生态地质环境具有水热充沛、矿产和旅游资源丰富，但存在地上地下双层岩溶空间结构和山高水深、地形陡峻、土壤贫瘠等两重性的特点，在人为活动的干扰影响下很容易导致生态退化，产生水土流失和石漠化等生态环境问题。本文在充分论述了西南岩溶区生态地质环境的这种特点的基础上，通过生态系统退化过程的机理分析，提出了岩溶生态系统退化是脆弱的岩溶生态地质环境和人类活动共同作用的结果的成因观点，以及以将人为活动限制在岩溶生态系统环境承载允许的范围之内作为前提条件，并辅以因地制宜开发水资源、合理利用土地资源、发展立体化生态农业、挖掘地方经济增长潜力、改善农村能源结构及生态移民等工程措施的生态系统恢复重建策略。
英文摘要	It is featured that there are abundant water and heat, mineral and tourism resources, but there are problem as being of bi-layer of structure spatially, and high mountains and deep water, sharp topography and impoverished soil, in Southwest China karst area. So, environmental problems, such as ecologic degradation is easy under human impact, which leads to soil erosion and rocky desertification. Through the analysis on the mechanism of ecologic degrading process, it is put forth that in this paper that the degradation of karst ecosystem are caused by the joint action of human impact and the natural fragile geologic environment. In addition, ecologic rehabilitation measures include the prerequisite of limiting the human activity within the scope of environmental bearing capacity, and then exploiting water resource in the light of local conditions, rationally using land, developing multi-level eco-agriculture, tapping the potentiality for the increase of local economy, improving energy structure in rural area, and ecologically migration etc. , are also proposed in the paper.
