据78条重点小流域验收资料分析,不同类型区的治理难度是黄土丘陵沟壑区>土石山区>风沙区>河源梁墹区。各类型区以基本农田为骨架,以水土保持林为主体,土石山区和风沙区水保林面积占到80％。黄土丘陵沟壑区和土石山区是以建设基本农田起步,河源梁墹区和风沙区是以发展牧业和林副产品为突破口。通过综合治理,各类型区经济都有快速增长,但到本世纪末还难以实现小康。必须把小流域治理引向商品经济大道,加快小流域治理由防护型向开发型治理的转变速度。
According to the analysis of acceptance data of 78 key small watersheds, it is difficult to manage different types of areas in loess hilly and gully areas> earth-rock mountain areas> wind-blown areas> Heyuan Liangpi area. Various types of areas to basic farmland as the skeleton, with water and soil conservation forest as the main body, rock and mountainous areas and windy sand area accounted for 80% of the area. The loess hilly and gully regions and the earth-rock mountain areas start with the construction of basic farmland. The Liangliu District and the wind-blown sandy areas of Heyuan are a breakthrough point for developing animal husbandry and forest by-products. Through comprehensive management, the economy of all types and regions has enjoyed rapid growth. However, it is still difficult to achieve a well-to-do society by the end of this century. The small watershed management must be led to the commodity economic avenue to speed up the transition speed of small watershed management from the protection type to the development type.
