中文摘要	石漠化的发生发展和迅速扩张,是导致中国喀斯特生态系统碳流失的主要原因,而石漠化地区固碳潜力巨大,是国家固碳增汇的主要地区之一。为了增强石漠化地区生态系统的固碳能力,基于喀斯特小流域是石漠化治理的基本生态水文地质单元的科学认识,使用遥感和地理信息系统,结合流域内物质组成结构与循环交换特征等,对中国南方喀斯特生态系统进行了小流域类型的划分与剖析。针对区域社会经济的优先发展方向和环境承载力,提出了不同类型小流域石漠化治理和固碳增汇的设计方案,建立了喀斯特高原集雨灌溉型高效生态农业模式、峰丛洼地人工种草替代型草食畜牧业模式、峡谷型发挥光热资源优势的特色林果模式、槽谷型发挥水土资源优势的竹果产业模式,为石漠化地区发展现代农业、推进区域经济发展和生态文明建设提供借鉴和参考。
英文摘要	Rapid development and expansion of rocky desertification are the main cause of karst ecosystem carbon loss in China. However, the rocky desertification areas have a tremendous potential of carbon sequestration,and are one of the main battlefields of carbon sequestration. Based on the scientific understanding that karst small watershed is a basic eco-hydrogeological unit of rocky desertification governance, we analyzed the watershed structure, matter composition, exchange and cycle characteristics, and classified the small karst watershed ecosystems in South China using RS and GIS, in order to promote ecosystem carbon sequestration capacity in this region. Based on local economic and social development priorities and environmental carrying capacity ,the design schemes of rocky desertification restoration and carbon sequestration for different types of small karst watershed were put forward. Some typical ecological restoration models were established,such as developing efficient ecological agriculture by rainwater harvesting and irrigation in karst plateau , developing plant-eating animal husbandry by planting artificial grass in karst depression ", developing featured fruit industry by using solar-thermal resource advantages of karst valley", developing bamboo and fruit industry by using water and soil resources of karst trough valley". These models provide reference for the development of modern agriculture ,local economy, and ecological civilization in rocky desertification region.
