辉县市位于豫北太行山南麓,地表岩性多为砂岩,片麻岩和花岗岩,水土流失形式多为面蚀和沟蚀.通过对小流域实施综合整治,从下到上依次为水平梯田、经济林、水保林和封禁的分层治理模式,配套相应的水利工程措施,基本实现泥不下山、溪水常流,控制了水土流失,改善了生态环境,对山区小流域治理有普遍的指导意义。
Huixian City is located in the south of the Taihang Mountains in the north of Henan Province, where the surface lithology is mostly sandstone, gneiss and granite, and the forms of water and soil erosion are mostly surface erosion and gully erosion. Through the comprehensive improvement of the small watershed, from the bottom to the top are horizontal terraces , Stratified management mode of economic forest, water conservation forest and embargo, with corresponding hydraulic engineering measures, the basic realization of the mud is not down, stream flow, soil erosion control, improve the ecological environment, there is a general guide to the management of small watershed in mountainous areas significance.
