【摘要】：土壤和水分是人类赖以生存的基本自然资源条件。由于不合理的环境资源开发利用和气候、地理条件原因,水土流失成为当前期待解决的主要的环境问题之一,加强水土保持工作是我国环境保护的重要内容。客观的水土资源赋予造成我国耕地资源不足,人均少、东多西少等人地矛盾突出,坡耕地资源开发利用与农业成为必然,但传统粗放的坡耕地耕作已经形成十分严重的水土流失问题,合理开发利用坡耕地资源已经成为当前水土保持工作的重点之一。在对我国水土资源调研分析过程中,分析坡耕地治理对于水土保持工作的重要性、我国坡耕地的现状以及耕地造成水土流失的原因和解决坡耕地资源开发利用问题面临的困惑,提出解决坡耕地问题的一些措施和建议。
[Abstract]:Soil and water are the basic natural resource conditions for human survival. Due to the unreasonable development and utilization of environmental resources and the reasons of climate and geographical conditions, soil erosion has become one of the major environmental problems to be solved. Strengthening soil and water conservation is an important part of environmental protection in China. Objective to cause soil and water resources of China's arable land resources shortage, less per capita, the contradiction in East than in West et al prominent, development and utilization of arable land resources and agriculture slope become inevitable, but the traditional slope land extensive cultivation has become the problem of soil erosion is very serious, reasonable development and utilization of sloping land resources has become the focus of the work of soil and water conservation one of the. In the research of water resources of China in the process of analysis, analysis of the causes of soil erosion caused by slope land management for the importance of the work, water and soil conservation in China and the current situation of cultivated land and solve the problems of development and utilization of sloping land resources face confusion, and puts forward some measures and suggestions to solve the problems of slope farmland.

【正文快照】： 1研究背景我国是世界上水土流失最严重的国家之一,全国有水土流失面积近356万hm2),占国土总面积的37%,需治理的面积有200多万hm2。据水利部2013年发布的《2011年中国水土保持公报》显示,我国现有的1.2亿hm2耕地中,坡耕地占2.24亿hm2。由于对耕地依赖性强,人地矛盾突出,形成土
