1 概况卧龙区位于南阳盆地北部边缘的斜坡过渡带,其中浅山区面积占17%,岗丘面积占38.1%,地理地貌特征呈“二山三岗五平原”分布。白河沿岸地下水丰富,北部、西北部地下水短缺,水资源不能互补互调,形成了全区水资源总量相对丰富,但分布不均的状况。全区4.9万hm~2耕地,水利能发挥效益的不足2.5万hm~2。新中国成立以来新打配3600多眼机井,发展了1万hm~2灌
1 Overview Wolong is located in the northern margin of the Nanyang basin slope transition zone, of which 17% of the shallow mountain area, hillock area accounted for 38.1%, geomorphological features were “two hills three five plains ” distribution. The groundwater of the Shirakawa coast is abundant. The groundwater shortage in the northern and northwestern regions can not complement and intermodulate water resources, forming a relatively abundant but uneven distribution of water resources in the whole region. The whole area is 49,000 hm ~ 2 cultivated land, and water conservancy can bring about less than 25,000 hm ~ 2 benefits. Since the founding of new China, more than 3600 eye drills have been newly deployed and 10,000 hm2 irrigation has been developed
