通过集水工程、沼气池与新型日光温室联体构筑提高水的利用率，探讨半干旱地区集水农业发展的新途径.在年降水量250～550mm的半干旱地区将雨水富集、存贮与节水措施相结合，可以有效解决水资源短缺的问题.将集水工程与日光温室、沼气池联体构筑，进行光、温、水、热的重组，发展高附加值的经济作物，提高水的利用率，使该地区发展高产优质高效农业成为可能.对日光温室中生态因子的优化，节水50％～70％，提高了地温与夜间的温度，降低了湿度，不仅提高温室生产力，还有效地降低了病虫害的发生；沼气池供给CO2及部分能量；阴棚把单屋面日光温室背面的遮阴区转化为生产区，种植耐阴作物与食用菌，实现阴、阳棚之间热量、CO2气体的交流.该模式可作为集水型生态农业的发展模式.

A combined structure of rainwater catchment, methane pool and reformed greenhouse was constructed to improve water use efficiency. The results showed that the combination of rainwater catchment, reserving techniques and water saving measures was efficient to resolve the problem of water deficiency in the semi-arid region with precipitation of 250～550mm. The combined structure of water catchment engineering, greenhouse and methane pool redistributed light,temperature, water and heat to develop higher benefits economic crops, and improved water use efficiency, which made it possible to develop high yield, and best quality agriculture in this region. Through optimizing the ecological factor in greenhouse, the water use was reduced by 50%～70%, and the soil temperature and night temperature were raised. This combined construction also improved productivity in greenhouse, and efficiently controlled plant diseases and insect pests. Methane pool provided CO2 and part energy source. The shady area back of the greenhouse was exploited by growing shady crops and epiphyte, which contributed to exchange energy and CO2 between light and shady house. This model could be used as water catchment agricultural development model in the region, and some other new approaches to water catchment agriculture in semi-arid region were discussed in this paper.
