| 摘 要： | 邛海是四川省第二大淡水湖泊,本研究是为更好地利用和保护该人类资源所做的基础研究工作之一。通过基于GPS-RTK技术以及测深仪的水下地形测量,结合原有历史资料,应用湖沼学理论,对邛海的湖盆形态进行定量化研究。经研究,邛海为南北长、东西宽湖体较为接近半球体形式的断陷湖泊,正常高水位(1510.3m)下最大水深18.80m,平均水深10.63m,湖长10.85km,湖面最大宽度5.24km,平均宽度2.53km,岸线长37.4km,湖面面积27.408km2,湖底真面积27.411km2,容积291.43×107m3。研究结果对邛海流域的深入研究及保护与开发提供了基础信息支持。 |

| Abstract: | Qionghai Lake is the second largest freshwater lake in Sichuan Province,the aim of this study is to use and protect this resource more efficiently.Through a GPS-RTK-based survey of the underwater terrain,along with the help of historical research,it investigates quantitatively the form of Qionghai lake based on the theory of limnology.As a result,the length from south to north is greater than that from east to west,the shape of the lake is approximately a hemispheroid,and it is a cave-in lake.There is no island in the lake.Under the water level of 1510.3 meters,the maximum depth is 18.80 meters,the average being 10.63 meters;the length of the lake is 10.85 kilometers,the maximum width is 5.24 kilometers,the average being 2.53 kilometers.The shore length of the lake is 37.4 kilometers,the surface area of the lake is 27.408 square kilometers,the real area of the lake bottom is 27.411 square kilometers,and the volume of the lake is 291.43 million cubic meters.The result of this research is useful for further research,protection,and exploitation of the Qionghai basin. |
