一、加强集水工程建设是实现节水型社会发展的重要组成水资源是基础性的自然资源和战略性的经济资源,是生态与环境的控制性要素。我国人均占有水资源量少,水资源时空分布极不均匀,与全国相比河南省则更少。自去年10月下旬开始,全省连续100多天无有效降雨,小麦受旱面积最高时近366.67万hm~2,其中严重受旱59.33万hm~2,有4.33万hm~2出现

First, to strengthen water catchment construction is to achieve an important component of water-saving society Water resources are basic natural resources and strategic economic resources, ecological and environmental control elements. China’s per capita possession of less water resources, spatial and temporal distribution of water resources is extremely uneven, compared with the national Henan province is even less. Since the end of October last year, the province has no effective rainfall for more than 100 consecutive days. The area with the most drought-affected area is nearly 3.6667 million hm ~ 2, of which 593,300 hm ~ 2 are seriously affected and 43,300 hm ~ 2 emerge
