1 水资源现状1.1 年均降雨量虽较充沛,但人均占有量很低慈溪市总面积1717.6km~2,其中海域面积342.35km~2,岸线至理论基面的海涂(浅滩)面积367.25km~2,陆地面积1008km~2,在海域和海涂上所产生的地表水径流均为咸水,按年均降雨量1344mm 计算,在陆域上多年平均径流量为5.03亿 m~3,在陆域内的地下淡水和微咸水径流量为0.32亿 m~3,多年平均水资源量为5.39亿 m~3,按101.09万人口计算,多年人均水资源占有
1 Current status of water resources 1.1 Annual rainfall is plentiful but average per capita is low. The total area of Cixi City is 1717.6km ~ 2, of which the sea area is 342.35km ~ 2. The area of the tidal flat (shoal) from the coastline to the theoretical base is 367.25km ~ 2, with land area of 1008km ~ 2. The surface water runoff produced in the sea area and the sea surface are all saltwater. Calculated on the basis of an annual average rainfall of 1344mm, the mean runoff over many years in the land area is 503 million m 3, The underground freshwater and brackish water runoff in the region is 32 million m 3, and the average water resource in many years is 539 million m 3. According to the population of 1.01 million, the per capita water resource share
