摘要

China is experiencing conflicts between its large population and scarce arable land, and between a demand for high produc-tivity and the severe soil erosion of arable land. Since 1949, China has committed to soil and water conservation (SWC), for which eight regions and 41 subregions have been developed to improve the environment and increase land productivity. To obtain information from the regional planning and strategies for SWC and to explore whether SWC practices simultaneously contribute to soil conservation, ecosystem functioning, and the livelihoods of local farmers, and to summarize the successful experiences of various SWC paradigms with distinct characteristics and mechanisms of soil erosion, this paper systematically presents seven SWC regions (excluding the Ti-betan Plateau region) and 14 typical SWC paradigms, focusing on erosion mechanisms and the key challenges or issues in the seven regions as well as on the core problems, main objectives, key technologies, and the performance of the 14 typical paradigms. In sum-mary, the 14 typical SWC paradigms successfully prevent and control local soil erosion, and have largely enhanced, or at least do not harm, the livelihoods of local farmers. However, there remain many challenges and issues on SWC and socioeconomic development that need to be addressed in the seven SWC regions. China, thus, still has a long way to go in successfully gaining the win-win objective of SWC and human aspects of development.
