【摘要】 农户宅院径流利用实地试验研究表明，修建水泥水窖并水泥处理院面为最佳宅院集水技术组合。这种技术可使组合集水效率比自然院面、屋檐下铺水泥面的集水效率提高７个百分点以上，入窖径流含沙量也显著下降。按试验所得水窖尺寸公式建造水窖，可较传统方法节约投入２３％，可集存宅院全年径流的６８．５％。利用宅院水窖发展庭院经济，可显著增加农户的经济收入。更多还原

【Abstract】 The experiment on use of runoff in peasant courtyard indicated that building .cement cellars and dealing with courtyard surface with cement was a best technological coordination for collecting runoff in courtyard. The runoff collecting efficiency by using this kind of method can be increased by 7 per cent than those,of natural courtyard surface or only paving cement under eaves, the silt content in runoff entering the cellars decreased obviously. Cellars set up according to cellar size formular by the experiment can save invest by 23% than that by traditional method,and can also collect and storage 68. 5% of the yearly total courtyard runoff. Developing courtyard economy by using water in cellars can obviously increase economic income of peasant households.更多还原
