摘要 笔者根据辽宁西北部太平沟小流域水土保持综合治理实践,阐述了通过调整小流域生态结构,即流域内植物群落水平结构、垂直结构、物质循环结构,再配合适当的工程措施,使水土流失大幅度减少,同时改善了饲料、肥科、燃料供求状况,提高了土壤肥力,增加了粮食产量和群众收入,使生态功能不断提高,实现了治理目的。 According to the comprehensive control measures of soil erosion in west Liaoning province, an effective approach for abjusting the ecological structure of the small watershed of Tarpiugguo-horizontal, vertical and material cycling structures of plants in the watershed, coordinated with appropriate engineering practices has been described.Some means were suggested to greatly reduce the loss of water and soil, to improve the conditions of supply and demand of forage fertilizer and fuel; to increase the soil fertility the grain output and the people's income and to improve the ecological functions.Finally the overall control has been realized.
