艾比湖水面蒸发量及生态环境保护

本文在论述了艾比湖水面８０年代以来趋于动态稳定状态的基础上，用两种方法分析论证了艾比湖水面蒸发量，并就艾比湖及其生态环境的保护提出相应措施。

EVAPORATION FROM THE WATER SURFACE OF EBINUR LAKE AND THE AROUND ECOLOGICAL ENVIRONMENTAL PROTECTION

Based on the available data of aerial and satellite photographs, it is considered that the Ebinur Lake maintains about 557.5km2 basically since 1980s. The two results of the annual evaporation from the water surface of Ebinur Lake calculated with two methods are close, that is about 6 x 108m3.Some comprehensive measures are presented for protecting Ebinur Lake and the around ecological environment according to the author's experience from the work and practice in this basin for many years. They mainly include:1. It is necessary to build an experimental field of evaporation from the water surface so as to obtain the firsthand data for the study of Ebinur Lake.2. The biological measures for maintaining and improving the ecological environment around Ebinur Lake are: (1) to increase the vegetation coverage of the dried area of Ebinur Lake so as to decrease the drift sand harmfulness; (2) to irrigate the Ganjiahu Sacsaoul Nature Preservation Zone with flood water so as to maintain a virtuous development of the ecosystem; (3) to build a green corridor along the railway so as to ensure the unimpededness of the new Eurasian Continental Bridge; (4) to protect the reed at the lake area so as to maintain a virtuous development of the ecosystem around the lake.3. In order to reduce the water loss in conveyance and increase the streamflow entering Ebinur Lake, it is suggested to build the water conveyance project from the Jinghe River to the lake.
