摘　　要：目的探讨中线水源区水土保持生态建设。方法采用文献分析和野外调研相结合的方法,并以实例进行论证。结果水源区内土壤侵蚀严重,其中坡耕地侵蚀模数高达6 000 t/a.km2,荒山、草坡等用地为1 000~3 000 t/a.km2。结论在水源区应形成以生态修复为主,结合工程措施的综合治理模式,可有效地减轻非点源污染。Aim Discussion on water and soil conservation ecological construction of middle route.Methods Based on literature analysis and field investigation.Results Soil erosion was serious in water district,erosion modulus in sloping was 6 000 t/a·km2,in barren was 1 000~3 000 t/a·km2.Conclusion The model based on ecological restoration and combination engineering measures could reduce non-point pollution effectively.
