摘　　要：本文以谢儿渠流域１９８３～１９９５年１３年的降水实测资料为基础，分析了流域降水在时间上的分布特点和一次降水量特点以及拦蓄利用的可能性，预测了可利用的降水量、径流量以及可发展窖灌农业的潜力．提出了流域利用水窖蓄水发展窖灌农业的方案。发展窖灌农业是雨育农业区小流域水土保持综合治理的一项重要内容，是农业种植从粗放经营向集约化经营转变的一种方式，是实现小流域经济持续发展的关键。On the basis of on-the-spot observation data of rainfsll in Xie'erqu small watershed in 13 years from 1983 to 1995,the paper analyses the temporal distribution features of rainfall,the feature of once rainfall and possibility of restoring and utilization,calculates the amount of usable rainfall and runoff and potential to develop pit-irrigation agriculture,puts forward the plan of developing pit-irrigation agriculture by restoring water in water pit in a watershed.Developing pitirrigation agriculture is an important part of soil and water conservation comprehensive management in a watershed in rainfall fed agricultural area,a way of crop planting from extensive management to intensive management,and a key point to realize sustained development of small watershed economy.
