辽宁省彰武县大四乡胜利沟小流域,1981年开始试点治理,目的是探索半干旱丘陵区小流域综合治理措施配置模式和加快治理速度的途径和方法。到1986年末,共完成综合治理面积2.53万亩,占水土流失面积的85.7％,年治理进度达16.6％。其中:造水土保持林16369亩,牧场改良和人工种草5722亩,维修和新修梯田6300亩,新建果园和老果园改造538亩,维修小(二)型水库1座,修筑塘坝3座,谷坊1354座,挖竹节壕23.77万米,修沟头防护131处,修作业路2.8万米。全流域林草覆被率由试点前的4％迅速提高到56.8％,基本控制了水土流失,生态环境开始由恶性循环向良性循环转化,经济效益、生态效益、社会效益均已充分显示出来,群众生活水平有了很大提高。
A pilot project was started in 1981 in Shengliou Small Watershed, Dazu Township, Zhangwu County, Liaoning Province. The purpose was to explore ways and means of allocating comprehensive control measures and accelerating the speed of management in small watersheds in semi-arid hilly areas. By the end of 1986, a total of 25,300 mu of comprehensive governance area had been completed, accounting for 85.7% of the total area of water and soil loss, with a progress rate of 16.6%. Among them, there are 16369 mu of water and soil conservation forest, 5722 mu of pasture improvement and artificial grass planting, 6,300 mu of maintenance and newly-built terraces, 538 mu of newly-built orchards and old orchards, 1 small reservoirs (type 2) Valley Square 1354, digging bamboo trenches 237,700 meters, repair ditch head protection 131, repair road 28,000 meters. The coverage rate of forest and grassland in the whole basin increased rapidly from 4% before the pilot project to 56.8%, basically controlled soil and water loss, and the ecological environment began to transform from a vicious cycle to a virtuous cycle. Economic benefits, ecological benefits and social benefits were all fully demonstrated. People’s living standards have been greatly improved.
