| 摘 要： | 以南小河沟为例，评价了水土保持工程措施、生物措施和生产力水平提高过程对流域水分环境条件的影响．结果发现南小河沟流域水环境在近５０年内发生了很大变化，坡面年总汇流量由治理前的１５．８３ｍｍ逐步减小为５．１６ｍｍ和现在的３．６６ｍｍ，未来１０年可能减到２．８６ｍｍ；塬面产流量却因庭院和道路面积增加以及建筑风格提高而逐步增大；坡地和沟谷的产流量逐步减小．同时生产力水平的提高进一步加强了水分小循环，削弱了水文大循环，改变了流域水均衡要素的定量分配

| Abstract: | Taken the Nanxiaohe watershed as a study
case, the influence of engineering and biological measures for soil and water conservation and
procedures for improving productivity level on the moisture environment was evaluated. During
the past 50 years, the moisture environment of Nanxiaohe watershed was significantly
changed. The total annual surface runoff decreased from 15.83mm before starting integrative
controls to 3.66mm at present time, and would reduce to 2.86mm in the future 10 years. The
plateau runoff increased, due to the increase of courtyard and road area and the improvement of
building style, and the slope and gully runoff gradually decreased. Meanwhile, the increased
productivity further reinforced the small cycle of water and weakened its big cycle, and changed
the quantitative distribution of water balance elements in watershed. |
