摘　　要：石漠化是我国西南喀斯特地区最为严重的生态地质环境问题,传统农业的耕作加剧了石漠化的发展。建植人工草地、发展草地畜牧业是保护喀斯特脆弱生态环境、发展当地经济的重要措施。文章综合论述了喀斯特石漠化概况及种草养畜治理石漠化效益、存在问题、解决措施和建议;并提出在石漠化地区发展草地畜牧业需要坚持"以畜定草"实现草畜平衡,建立牧草病虫害与牲畜疾病综合防治体系,建立灾害应急机制,完善草地畜牧配套设施,强化科技支撑与国家政策扶持,发展先进技术,完善产业链条,提升畜产品附加值,筛选抗旱耐贫瘠高产牧草,防控毒草。Rocky desertification is the most serious ecological, geological and environmental problem in the karst areas of southwest China. The traditional farming practices intensify the development of rocky desertification. To plant artificial grassland and develop grassland livestock industry are the important measures to protect the fragile karst ecological environment and develop the local economy. This paper comprehensively discusses the general situation of karst rocky desertification as well as the beneficial results, existing problems and suggestions of grass - planting and livestock - raising to bring rocky desertification under control. It also proposes that the development of grassland animal husbandry in rocky desertification area needs to adhere to the principle of selecting grass based on livestock to achieve forage and livestock balance, and needs to es- tablish the comprehensive prevention and control system of forage - grass diseases and pests, and livestock disease; establish disaster response mechanism, and improve grassland animal husbandry supporting facilities. In addition, strengthening scientific, technological Support and the sup- port from national policy, developing advanced technology ,improving the industrial chain, promoting the added value of livestock products, selec- ting drought and barren resistant forage grasses, preventing and controlling poisonous weeds are all of significance.
