摘要:利用多源、多时相的数字遥感影像和呼伦湖周边地区水文气象资料,采用基于卷积神经网络的高分辨率图像重构方法研究了1999—2019年呼伦湖面积、库容变化情况。结果表明:2003—2012年呼伦湖的面积逐年减小,湖泊水量逐年下降,2003—2012年补给呼伦湖的乌尔逊河与克鲁伦河的多年平均径流量分别为1.30亿m3与1.41亿m3,分别只有1991年以前多年平均径流量的21%与24%;而2003—2012年呼伦湖平均水面年蒸发量为17.5亿m3,平均年湖面降水量为3.25亿m3;地下水补给呼伦湖的年平均水量为5.3亿m3,主要来自新生代玄武岩地下水,哈拉哈河源头火山玄武岩地下水通过熔岩管道集中外泄,据此推断补给呼伦湖的地下水来自跨流域的外源水。

Abstract:By means of multi-source and multi-temporal digital remote sensing images as well as hydrometeorological datas around Hulun Lake, high-resolution image reconstruction methods based on convolutional neural networks were used to study the change of the area and storage capacity of Hulun Lake from 1999 to 2019. The results show that the area of Hulun Lake has decreased year by year from 2003 to 2012, while the water volume of the lake has decreased year by year. The multi-year average runoff of Wuerxun River and Kerulen River supplying Hulun Lake from 2003 to 2012 was 130 million m3 and 141 million m3 respectively, which accounts for only 21% and 24% of the multi-year average runoff before 1991. From 2003 to 2012, the average annual evaporation from water surface of Hulun Lake was 1.75 billion m3 and the average annual precipitation of the lake surface was 0.325 billion m3. The average annual amount of groundwater replenishing Hulun Lake was 0.53 billion m3. The main source is Cenozoic basalt groundwater and the volcanic basalt groundwater at the source of the Halaha River is leaked through lava pipes. Based on this, it is inferred that the groundwater replenishing Hulun Lake comes from the allogenic water across the basin.
Key words:  water balance  groundwater recharge  remote sensing image  convolutional neural network  Hunlun Lake
