一、广东省水资源特性 全省土地面积21.2万km~2,多年平均河川径流总量为2110亿m~3,径流深995mm。另有珠江、韩江、鉴江、和九州江等主要河流从外省、区流经我省出海的客水3,851亿m~3。全省浅层地下水约占河川径流总量的18％,即约379亿m~3;基本上是由地表水补给的。深层地下水约为415亿m~3。故地下水总量为794亿m~3。全省水资源总量为2,525亿m~3
First, the characteristics of water resources in Guangdong Province, the province’s land area of 212,000 km2, the average annual runoff amount of 211 billion m 3, runoff depth 995mm. In addition, major rivers such as the Pearl River, Hanjiang River, Kam River, and Kyushu River flowed 385.1 billion cubic meters of passenger water from other provinces and districts to the sea of our province. Shallow groundwater in the province accounts for about 18% of total river runoff, or about 37.9 billion m 3; basically, it is recharged by surface water. Deep groundwater is about 41.5 billion m 3. Therefore, the total groundwater is 79.4 billion m ~ 3. The total amount of water resources in the province is 252.5 billion m ~ 3
