水土保持与山区农业可持续发展

河南省地处南北气候和山区向平原双重过渡带,受特殊气候、地理环境和人类活动等因素的影响,水土流失严重,山区农业生产条件和生态环境脆弱。通过对水土流失危害以及水土保持在改善生态环境与农业生产条件中的作用分析,指出了水土保持是山区农业可持续发展的根本。提出搞好水土保持,促进山区农业可持续发展的对策是：预防为主,保护优先；加大水土流失治理力度；重点抓好以坡改梯为主的基本农田建设；切实加强拦沙蓄水工程和坡面水系配套工程建设；强化监督管理工作,遏制人为造成新的水土流失。

Soil and Water Conservation and Agriculture Sustainable Development in Mountain Areas

He'nan province locates in transition areas of both south climate to north climate and mountain to plain area.Influenced by special climate,geography environment and human being actions etc.,the situation of soil and water losses is serious and the productive conditions and ecological environment are fragility in these mountain ar- eas.Basis on the analysis of harm of soil and water loss and the function of soil and water conservation to improve the productive conditions and ecological environment,the paper points out that soil and water conservation is the root to maintain agricultural sustainable development in mountain areas.The countermeasures of improve water and soil conservation and maintain agricultural sustainable development in mountain areas are prevention and pro- tection,erosion control and construct farmland with high productivity by terracing on the slope,reinforce the pro- jects of blocking sands and sluice and water system match on the slope,strengthen supervising and management and keep the new artificial water and soil losses within limits.
