漫岗丘陵黑土侵蚀区建立水土保持型生态农业模式的探讨

东北漫岗丘陵黑土侵蚀区,水土流失比较严重,导致地力衰退、生态经济恶化。拜泉县从综合治理水土流失入手,实行生物与工程结合,治理与开发同步,在不同类型区创立了岗坡洼综合治理开发、农林牧协调发展、基塘农业、庭院生态经济良性循环四种水土保持型生态农业模式,取得了良好的生态效益和经济效益,为漫岗丘陵黑土侵蚀区的治理开发,展现出资源永续利用、经济持续发展的美好前景。

Probe into the Establishment of Eco-agricultural Models for Soil and Water Conservation in Rollied Hilly Black Soil Erosion Area

In rollied hilly black soil erosion area of northeast China, serious soil loss caused degradation of land fertility and deterioration of ecologic economy. Four eco-agricultural models for soil and water conservation, such as the comprehensive harnessment of hillsides and gullies; coordinative development of agriculture, forestry and animal husbandry; benign cycle of base-pond agriculture and benign ecologic economy in courtyards, were set up in different areas combining biologic measures with engineering measures, prevention with ex-ploitation in the comprehensive harnessment of soil loss in Baiquan County. Good ecologic effect and eco-nomic benefit had been made to show a magnificent prospect of long term utilization of resources and con-tinued development of economy for the harnessment and exploitation of gullied hilly black soil erosion area.
