盐池县刘窑头小流域通过开展以大面积自然修复为重点,以开发利用浅层地下水建立稳产高产农田为基础,以发展舍饲养羊和柳编业增加收入为主攻方向的综合治理,共治理水土流失面积17.41km2(其中封育面积占71.5%,治理开发面积占28.5%),治理后流域林草覆盖率由30%左右提高到85%,人均产粮由305kg提高到708kg,人均纯收入由629元增加到1512元,实现了治理一方水土,改善一方环境,发展一方经济,富裕一方群众的目标。刘窑头村的巨大变化,给我们有三条重要的启示:第一,实行自然修复是生态建设中高效快速、费省效宏、安全可行的一条重要措施;第二,依靠自然修复要妥善解决农民的生产、生活,以小面积的高效开发换取大面积封育保护;第三,依靠自然修复要有当地群众的广泛参与,有得力的管护措施作保证。
Yancheng County Liu Yaotou small watershed through the implementation of a large area of natural restoration focused on the development and utilization of shallow groundwater to establish stable and high yielding farmland as the foundation to develop Sheep and Liubian increase revenue as the main direction of the comprehensive treatment of water and soil The drainage area is 17.41km2, of which 71.5% is sealed and 28.5% of which is under development. After the management, the coverage of forest and grassland in the river basin has been raised from 30% to 85%, and the per capita grain yield has increased from 305kg to 708kg. 629 yuan to 1512 yuan, achieving the goal of governing one side of the soil and water, improving one side’s environment, developing one side economy and enriching the other side. The great changes in Liuyao Toucun give us three important revelations: First, the implementation of natural restoration is an important measure in ecological construction that is efficient, rapid, cost-effective and safe and feasible. Second, it is necessary to properly solve the problem of natural restoration Thirdly, relying on the extensive participation of local people and the effective management and protection measures by means of natural restoration, peasants’ production and livelihood should be developed in a small area with efficient development in exchange for large-scale enclosure protection.
