辽西易旱区雨水资源跨时空调控技术的研究

辽宁西部易早区地域辽阔，旱灾频繁，雨水资源时空分布与作物生产需要不吻合；多年来，并未把着眼点放在拦蓄与科学利用雨水资源上。本文总结了近年来这一地区雨水资源跨时空调控技术，包括空间上对降雨拦、蓄和时间上的夏深松、秋覆膜、春增墒技术，讨论了这一技术所收到的效果及其原理，对今后这一技术体系的形成、完善和推广应用做出了展望。

Study on Regulating Rainwater of Incidental Zone by Spanning Space-Time in Western Liaoning

The terrain is expansion in incidental zone of western Liaoning. The rainwater for crop production is autarky although the drought taken place frequently. The primary problem is that there have no synchronization between the space-time distribution and crop production. But runoff holding-up and its utilizing has been ignored. The held-up moisture on the field have not been used effectively yet. A distinct effect has been gotten By using a series of technology with holding-up runoff and saving it.
