摘要
河南省汝阳县浑椿河小流域是水利部淮委的“试点”小流域之一。本文通过介绍其在1986～ 1999年的治理经验与近几年的效益发挥情况 ,研究探讨了水土保持对减少水、土、肥流失及增加当地农、林、牧、副诸业所起的作用 ,并进行了近、远期效益综合分析。虽然其中对减少的土壤侵蚀及相应增加的作物经济效益估算是粗略的 ,但初步分析结果表明 。
The small watershed of Hunchun River in Henan Provice is one of the pilot sites designated for small watershed management by the State Bureau of water mangement.This paper summarized the experience of water management in this area during 1986～1999, as well as the benefits achived in the recent years.The effect of water soil conservation on decreasing water,soil and fertilizer erosion,and increasing the local income in agriculture,forestry,and stockbreeding is discussed.The short and long term integrated benefit is analyzed also.Although the accuracy on the estimation of soil erosion decrease and crop benefit increase is rather limited,the primary results indicate that the integrated management with water soil conservation in small watershed is economically beneficial.
