1 全市水资源现状1.1 水资源总量安阳市属于资源型缺水城市,全市水资源总量为16.4亿m~3,人均占有量322m~3,公顷占有量4515m~3,低于全省平均水平,分别为全国的1/7和1/6。总体气候特点是春旱少雨,夏季炎热,雨量集中。汛期7、8两月降水量一般占全年的55%,地表洪水径流调节困难。1.2 地下水利用程度高全市现有水利工程主要有:大型水库1座,中型水库7座,小型水库110座,大中型灌区8处,机电井7.5万多眼。在供水总量中,地下水占80%以上。1.3 水资源供需矛盾突出近20年来,全市的总供用水量由1980年的17.96亿m~3,增加到目前的21亿多立方米。而地表水资源却在明显减少,这
1 The status quo of the city’s water resources 1.1 The total amount of water resources Anyang City is a resource-laden city, the city’s total water resources of 1.64 billion m 3, the per capita possession of 322m ~ 3, hectare occupancy 4515m ~ 3, lower than the provincial average Level, respectively, the country’s 1/7 and 1/6. The overall climate is characterized by spring drought, hot summer and heavy rainfall. The precipitation in July and August in flood season generally accounts for 55% of the whole year, and the adjustment of surface flood runoff is difficult. 1.2 The high degree of groundwater utilization The city’s existing water conservancy projects are: a large reservoir, 7 medium-sized reservoirs, 110 small reservoirs, large and medium-sized irrigation 8, more than 75,000 mechanical and electrical wells. In the total water supply, groundwater accounts for more than 80%. 1.3 Water Supply and Demand Contradiction Outstanding In the past 20 years, the total water supply of the city increased from 1.796 billion m 3 in 1980 to over 2.1 billion m 3 at present. The surface water resources are obviously reduced, this
