长江流域黄土丘陵区综合治理模式初探——以郭罗沟流域为例

在长江流域黄土丘陵区，郭罗沟流域探索出一种成功的水土保持开发治理模式，即"梁峁造林戴帽子，坡耕地上修台子，地埂种草挂胡子，山腰果园系带子，沟道工程穿靴子"。该模式的实施使流域内农村产业结构得到调整，使流域生态系统结构、功能转向良性循环。该模式为长江流域黄土丘陵区乃至周边地区流域综合治理提供了一种较成功的经验。可为区域综合治理起到示范作用。

Primary Discussion on Model of Comprehensive Management of Small Watersheds in Loess Hilly-gully Area in Yangtze River Valley--Taking Guoluogou Valley as an Example

The model of comprehensive management of small watersheds, which afforested on the Weir and Mound of small watersheds, terraced on slope, seeded the fine fodder grasses on ridges, planted economic forest on the mid-hill and built the check dam in valley, was set up and practiced in Guoluogou small watersheds. The rational agricultural structure was set up in this watershed. The structure and function of ecosystem was turning to good circle in this watershed. The model provided a successful comprehensive management experience to loess hilly-gully area of Yangtze River valley and the around other areas.
