发展集雨节灌深化水利富民-考察甘肃发展集雨工程的几点启示

在对甘肃省集雨节灌考察的基础上，提出了推动北京市集雨节灌水利富民工程发展的思路和措施。甘肃省实施的集雨工程，总结出了雨水集蓄利用三条途径：修筑梯田，拦蓄雨水，发展雨养农业；利用庭院、场院和屋顶集雨，发展庭院经济；利用道路集雨，发展大田作物节水灌溉。同时，也探索出了三种集雨节灌水利富民综合开发模式：集雨节灌与设施农业相结合；集雨节灌与生态农业、流域治理相结合；集雨节灌与观光农业、休闲娱乐相结合。借鉴甘肃成功的做法和经验，发展集雨节灌，五小水利工程网络化，建设有北京特色的集雨节灌水利富民工程，是北京应当深入思考和认真实施的事情。

Developing rainwater - harvesting and water - saving irrigation to deepen water conservancy for enriching farmers-enlightenment from investigating the rainwater- harvesting projects in Gansu Province

On the basis of investigating the rainwater-harvesting projects in Gansu Province, this paper puts forward some measures for developing rainwater-harvesting and water-saving irrigation and water conservancy projects for enriching farmers in Beijing. Three ways of rainwater collection and utilization are practiced in Gansu Province: constructing terraces to reserve rainwater for developing rainwater agriculture, making use of courtyards and house roofs to collect rainwater for developing yard-planting; using roads to collect rainwater for developing water-saving irrigation in farmlands. Moreover, three patterns of rainwater-harvesting and water-saving irrigation for enriching farmers have been developed in Gansu Province f integrating rainwater-harvesting projects with greenhouse agriculture, with ecological agriculture, and with sightseeing agriculture. Beijing should learn from Gansu Province to develop the rainwater-collecting agriculture and build five mini-conservancy projects into a complete system.
