关于西南岩溶区石漠化土地恢复重建目标的讨论

根据恢复生态学相关研究进展和西南岩溶区石漠化土地综合治理现状，探讨了石漠化土地生态恢复重建的不同空间尺度目标、阶段性目标、植被生态建设目标、社区文化建设目标和效益目标。指出防治岩溶石漠化的实质绝不仅仅是岩溶山区的水土保持问题和恢复植被，只有实现环境恢复、经济发展和社会进步三者的协调发展，生态建设与富民增收并举，石漠化等环境问题才能得到真正的全面解决。因此，近期石漠化综合治理模式目标必须结合市场重新认识资源环境优势，由扶贫型向提高生活质量型转变，由单一坡改梯向多途径特色农业转变，由防护型向开发型转变，由政府主导向参与式转变，从而打破岩溶脆弱生态背景上土地退化的恶性循环。

A DISCUSSION ON RESTORATION AND REHABILITATION OBJECTIVES OF ROCKY DESERTIFICATION LAND IN SOUTHWEST KARST REGION OF CHINA

Based on the current trends of restoration ecology and the actualities of comprehensive control of karst mountain areas in southwest China, the restoration and rehabilitation objectives at different spatial scale and different phases, vegetation ecological construction objectives, community and culture construction objectives and benefit objectives are discussed in this paper. The essential to prevent and cure rocky desertification is not merely the water and soil conservation and vegetation restoration, only the harmony of environmental restoration, economic development and social progress, the enhancement of ecological construction and the wealth of peasantry are realized jointly can rocky desertification be controlled completely. Therefore, for drawing the comprehensive objectives of rocky desertification control in the near future the resources and environment superiority should be combined with market, the model of helping the poor be turned into that of enhancing the living quality, single sloping field terracing be turned into multiform agriculture with distinguishing features, the defence model be turned into development model, and government domination be turned into people's participation, and all those are to break the vicious circle of land degradation in fragile karst eco-environment.
