雨水利用,微灌技术与庭院经济

干旱半干旱地区缺水导致人们生活饮用水困难，更制约着工农业经济的发展。建集蓄雨水工程－集流场，蓄水水窑，可解决当地群众的生活用水，还可用剩余的水发展庭院经济，脱贫致富。在这类地区微灌技术成为利用集蓄的雨水发展庭院经济的纽带。但目前雨水利用与微灌技术的结合尚处较低水平，有待进一步研究适用于这类地区的设备和技术，使微灌给干旱半干旱地区人民带去福音。

Rainfall use,mini-irrigation technique and courtyard Economy

Water deficiency causes 1seople difficulty to get drinking water and limit the development of industry and agriculture in arid and semi-arid regions. To construct collecting ra1nfall engineeringcollecting field, water cellar-ean Provide drinking water for local people, and develop courtyard eeonomy. to get out of poor and become rich. The mini-irrigation technique is the key to using rainfall collected to develope courtyard economy. But the combination between ra1nfa1l use and mini-irrigation technique is still at a low level. and needs further studying the suitable equ1pment and techniques for this region, this benefting the people in arid and semi-arid regions.
