摘　　要：小流域综合治理是各地区水土保持的基本途径之一。根据对四川紫色土丘陵区综合治理小流域（四川南部县鹤鸣观小流域）水土流失多年（1985～2001年）监测,结果表明：①紫色土丘陵区小流域无论是以工程措施还是以生物措施为主进行综合治理,其水土保持效果都是十分有效的,而且是稳定的;②以工程措施为主的综合治理,其水土保持较以生物措施为主的见效快;③这两种综合治理模式,经过一定时期后,其水土保持效果接近。因此,综合治理水土流失,应因地制宜采取治理模式。The integrated countermeasure of small watershed is one of basic means of soil and water conservation. The results, based on the observation of soil and water loss in hilly area of Nanbu, Sichuan basin for period of 1985 -2001, showed that ① the efficacy of integrated countermeasure mainly either by engineering practices or by planting alternatives, is very satisfied and steady; ② The efficiency of integrated countermeasure mainly by engineering practices is more apparent than that of by planting alternatives at initial stage;③ The effectiveness of soil and water conservation for the two integrated countermeasure means is stepwise close after a certain period. Therefore, the integrated countermeasure of soil and water loss should be adjust the measures to local conditions.
