自2008年10月起近110d以来,河南有效降水≤15mm,河南省小麦受旱面积达276.67多万hm2,其中严重受旱46.67万hm2,有3.33万hm2出现麦苗枯死现象。旱情如此严重的元凶固然是气候,但从另一方面,也足以说明当前灌溉能力之脆弱。影响气候可能人的能力有限,但是用合理灌溉来提升抗旱能力却是必要的。 Since the last 110 days from October 2008, the effective precipitation in Henan has been less than 15mm. The drought-affected area of ​​wheat in Henan Province has reached 2.7667 million hm2, of which 466,700 hm2 are seriously affected and 33,300 hm2 withered the phenomenon of wheat seedling withering. While such a serious culprit in the drought is certainly a climate, on the other hand, it is enough to explain the fragility of the current irrigation capacity. Capacity to influence people with climate is limited, but it is necessary to improve drought resilience with proper irrigation.
