| 摘 要： | 在分析小流域的自然条件及水土流失特点的基础上，提出了流域水土保持型生态农业体系建设的原则及其配置措施。通过建立水土保持型生态农业体系，流域实现了生态效益、经济效益和社会效益有机统一的良性生态经济系统。植被覆盖率由1985年的30．7％提高到89．0％，侵蚀模数连年减少；粮食总产量由1985年931．2万kg提高到1998年的1424．6万kg；人均纯收入1998年达到3406元，是1985年的18．4倍。 |

| Abstract: | On the basis of analyzing natural factors and characteristics of soil erosion in valley, bring up fundamental principia and measures for construction of ecoagricultural system of soil and water conservation type. Because of constructing ecoagricultural system of soil and water conservation type, it have a good ecobenefit,economicbenefic and socialbenefit as a wellcircled ecoeconomic system. The coverage of vegetation raised to 89.0% in 1998 from 30.7% in 1985,and modulus of soil erosion decreased annually;the total output of food supplies amounted to 14.246 millions kg in 1998, that was 9.312 millions kg in 1985;3406 $ net income were obtained per capital,and it was 18.4 times compare to 1985. |
