镇平县位于河南省西南部,伏牛山余脉五朵山南麓,南阳盆地西北侧,全县人口93万,耕地面积7万hm~2,是一个以粮食生产为主的农业大县。全县水资源均值总量4.317亿m~3,其中地表水为3.452亿m~3,地下水0.865亿m~3,平水年水资源总量为3.937亿m~3,而偏枯水年水资源总量只有2.798亿m~3。水资源年际变差较大,时空分布也不均匀,各区域之间很不平衡,严重影响镇平经济的快速发展。特别是近几年农业、工业和生活用水量增加,水资源紧缺问题日益突出。如何利用有限的水资源,保证各行业的正常、持续发展,从而推动整个镇平经济的发展,是新世纪重中之重的课题。
Zhenping County is located in the southwestern province of Henan Province, the foot of the Wusiu Mountain Wusuo Mountain southwest, northwestern Nanyang Basin, the county population of 930000, arable land area of 70000 hm ~ 2, is a major grain-producing agricultural county. The total average water resources of the county is 431.7 million m 3, of which surface water is 345.2 million m 3, groundwater is 0.855 billion m 3, total water resources in plain water is 3937 million m 3, Only 279.8 million m ~ 3. The annual variation of water resources is large, the distribution of time and space is not uniform, and the imbalance among different regions seriously affects the rapid economic development in Zhenping. Especially in recent years, the water consumption in agriculture, industry and daily life has increased, and the shortage of water resources has become increasingly prominent. How to make use of limited water resources and ensure the normal and sustainable development of various industries so as to promote the economic development of the entire town is the most important issue in the new century.
