| 英文摘要 | Shortage of water is the key limiting factor for agricultural development of Beijing. Rainwater harvesting (RWH) could provide an alternative water source for greenhouse agriculture, but local natural and socioeconomic conditions challenge the application of the technology. This paper analyses the advantages and disadvantages of different types of greenhouse RWH in Beijing, and describes a new greenhouse RWH system demonstrated in 2008 in Huairou, a suburb district of Beijing. It analyses the efficiency, cost-benefit ratios and limiting factors of the new system. The results show that with the new system, rainwater harvesting efficiency can be as high as 66% (of total rainfall) and the rainwater usage rate can reach 69% of total water usage. The ratio of benefit to cost of government investment can be 1.84, and the ratio of benefit to cost of a farmer's investment could be 1.68 provided the project is designed to save water and also increase income. This paper also suggests a number of measures to increase the efficiency of the system in order to apply it on a large scale. |
