水土流失作为环境恶化的主要原因之一,是土壤学和环境生态学研究的热点。控制水土流失,有利于人类经济与社会的可持续发展。退耕还林(草)作为一项治理水土流失的有效政策与方法,一直受到人们的关注。从林草植被对水土保持功能的研究现状、退耕还林(草)的技术标准、效益评价等方面进行了回顾总结,在此基础上指出目前存在的主要问题以及发展趋势,对退耕还林(草)与水土保持关系的研究和退耕还林(草)政策的进一步完善和落实,具有一定的指导意义。
Soil and water loss as one of the main causes of environmental degradation is one of the hot topics in soil science and environmental ecology research. Control of soil erosion is conducive to the sustainable development of human economy and society. Returning farmland to forest (grass) as an effective policy and method to control soil and water loss has always been the focus of attention. This paper reviews the research status of soil and water conservation function of forest and grassland vegetation, the technical standards of returning farmland to forest and grassland, the benefit evaluation and so on. Based on this, it points out the main existing problems as well as the development trend, Grass) and the relationship between soil and water conservation and the policy of returning farmland to forest (grass) to further improve and implement a certain degree of guiding significance.
