| 摘 要： | 通过修建径流小区,对北京市房山区黄院采石场的治理进行了连续两年的坡面径流观测,用对比分析的方法研究了采石场治理初期不同年份内不同治理措施的水土保持效益。结果表明,在采石场治理初期,不同的坡度、不同的治理措施、不同的植被覆盖度均对坡面水土流失的影响有较大差异。当坡度为25°时,铺设生态袋措施能够有效防治水土流失;当植被覆盖度小于15%时,影响水土流失的主要因素为松散体坡面的孔隙度;当植被覆盖度大于60%时,影响水土流失的主要因素是降雨量和降雨强度。

| Abstract: | Soil and water conservation benefits of different manage measures in different years were analyzed by applying the method of comparative analysis and monitoring the surface runoff of the different management stations of the Huangyuan quarry runoff plots with two consecutive years. The results sowed soil and water conservation benefits of different types of slopes, different control measures and different vegetation coverage varied considerably in the early treatment in quarry. The runoff plot with slope of 25°using the ecological bags reduced soil and water loss significantly. The main reason of soil and water loss was soil porosity of the loose media slopes when the vegetation coverage was less than 15%. Rainfall and rainfall intensity became the most important reason when the rate of vegetation coverage was more than 60%. |
