摘要
潮、滦河流域，属国家级水土流失重点防治区。“八五”期间，在滦平县进行了小流域综合治理试验、示范，采取了开发型的综合治理模式。以治理生态环境为基础，发展经济为目的。具体措施：调整种植业结构；大力开发荒山发展林果业；种草养畜。“八五”结束时，工程区内种植业每ｈｍ’增值２５５０元，林业每ｈｍ２增值１３３０元，侵蚀模数由治理前的１６４６ｔ／（ｋｍ２·３）降至６５ｌｔ／（ｋｍ２·ａ）取得明显的经济、生态和社会效益，生态环境呈良性循环，小流域经济系统得以持续发展。
Chaohe and Luanhe watershed is the key district of national conservation,In the peri-od of“the Eighth Five-year Plan”,the experiment and demonstration for comprehensive harnessof small watershed are conducted in Luanping county’the exploitive model which takes the harness of ecologic environment as a basis and the economic development as a object,is adopted。The concrete measures are as follows:to regulate the structure of plantation;to exploit wastemountainland vigorously,and to develop forestry and pomicuIture;plant herb to raise animals,and to correctly handle the contradictions between forestrv and animal husbandry.At the end of“the Eighth Five-year Plan”,the production of farming increased 2 5 50 Yuan/hm2,forestry in-creased 1300 Yuan/hm2,the erosive modulus reducedfrom l 646t/(km2.a)to 651t/(km2.a).Then,the obvious benefits of economics,ecology and socienty are obtained,so that the economicsystem keeps us a steady development.
