中文摘要	喀斯特山地石漠化作为一种土地退化的特殊景观现象,严重制约着西南山区经济的可持续发展,加剧了该地区的贫困程度.近年来,在国家、各级政府及广大民众的齐心合力下,石漠化治理取得了一定的可喜成绩,但石漠化的总体增长趋势仍未得到基本遏制,治理形,势依旧严峻.本文尝试将现有的喀斯特石漠化治理理论、原则和途径进行归纳和总结,并就目前治理过程中存在的问题提出建议和注意事项.在西南喀斯特山区的石漠化治理中,我们应该遵循以下原则:治理要符合自然客观规律、经济与生态兼顾并重、因地制宜、分区域治理、技术与措施的可操作并维持生态系统的可持续发展.通过多年的石漠化治理实践,人们摸索出了许多成功、有效的治理途径,包括生态修复工程、基本农田建设工程、水资源开发利用工程、沼气工程、生态移民、草地畜牧业和生态农业的发展.然而,石漠化治理过程和治理之后仍然存在诸多问题:退耕还林还草的生态补偿,生态移民的安置及素质教育,石漠化治理范围的确定,沼气池的管护、维修和改造,草地畜牧业发展中牧场规模的大小、管理人员经济管理意识的培养、养殖技术的提高,"坡改梯"工程的设计、建造及梯坎的改良,"植树造林"项目中物种的选择及造林管林结合等方面,进一步思考和解决这些问题,可对长期的喀斯特石漠化治理实践起到一定的指导和参考作用
英文摘要	The rocky desertification in karst mountain areas of southwestern China,a specific phenomenon of land degradation,is one of the most serious environmental problems and a hotspot of ecological research. The critical-situation of population, resources and environment restricts seriously the sustainable development of this region. This resulted in the poverty which will become worse and worse. During recent years the central and local governments and the public worked hard to attempt to address this problem. Some of scientific and technological achievements about the comprehensive treatment of rocky desertification have been successfully obtained. However the increasing trend of rocky desertification has not been basically restrained. The governance situation still remains rigorously. In this paper we attempt to summanze and synthesize the existing theory, fundamental, and.approach of karst rocky desertification treatment. Advice and attentive issues resolving the existing problems of present treatments are provided. During the comprehensive treatments of rocky desertification in karst mountain area of southwest China,we should follow some principles. The treatment must accord with natural rules. Both economic development and ecological construction must be equally paid attention to. Different places and different situation of rocky desertification must be treated in different ways, and such different treatments must be performed according to ’ecological divisions. Furthermore technique and measurement should be exercisable in order to maintain the sustainable development of ecosystems in this degraded mountain area. Many successful and effective approaches have been explored through the practice of long-term rocky desertification treatments. Such approaches include ecological restoration engineering, essential agricultural construction engineering, exploitation and utilization engineering of water resources, marsh gas pit engineering, ecological migration, pasture and stockbreeding, and ecological agriculture development. However many problems still existed during and after the treatments. Following suggestions of solving the existing problems must be paid more attention:the ecological compensation of retuming farmland to forest and grassland (grain for green policy);resettlement of ecological migration and the ability oriented education;determination of the range of rocky desertification control:management, maintenance and reformation of marsh gas pit; scope of the pasture, staff training of the awareness of economic management, and improvement of animal husbandry technology in the development of pasture livestock breeding;design, construction and refinement of side-slope in the "transforming hillside to terrace" ;and the selection of plant species and combination of afforestation and forest management in "tree planting and afforestation" projects. We hope that such recommendations and attentions can play important roles in guiding the long-term practice of Karst rocky desertification treatment
