关于抚仙湖的开发利用问题,《人民珠江》曾刊登两文。本文拟就个人接触的情况,谈一些设想。一、关于湖区的一些基本特点 (一)库容大,来水量少。抚仙湖是我国第二个深水湖,,湖水面积220平方公里,储水185亿立方米。据海口河水文站26年的资料分析,湖区年降水量为900～1,000毫米,蒸发量1,600毫米。年均逛流量2.4亿立方米。扣除蒸发、渗漏,库塘蓄水以及沿湖一部份农田的灌溉提水量以外,抚仙湖平均每年的净入湖水量,只有1.2亿立方米,约
On the development and utilization of Fuxian Lake, “People’s Pearl River” has published two articles. This article intends to talk about some ideas about personal contact. First, on the lake some of the basic characteristics (a) storage capacity, less water. Fuxian Lake is China’s second deep lake, the lake area of 220 square kilometers, 18.5 billion cubic meters of water storage. According to the data analysis of 26 years of the Haikou River Hydrological Station, the annual precipitation in the lake area is 900-1,000 millimeters with an evaporation of 1,600 millimeters. The average annual flow of 240 million cubic meters. Excluding the evaporation, seepage, reservoir pond storage and part of the farmland along the lake irrigation water, Fuxian Lake average annual net lake water, only 120 million cubic meters, about
