内容 研究概要:Yanji Basin is a subsidence of the earth's crust that is enclosed within the Range of Mountain Tianshan, The Lake Bosten, which is located in the lowest place of the Yanji oasis, is in the center part of the Basin. The three main inflow rivers, named Kaidu, Huangshui and Qingshui, derive from the northwestern and northern mountain areas. The outflow is only Kongque River, which located on the southern tip of the basin. The Oasis mainly consists of the irrigation areas, reed lands and other water areas. With the examination of the hydrological characteristics of the Basin, which are studied based on the analysis of available data from 1976 to 1989 at the hydrological stations around the Yanji Oasis, we built up a water balance model of Lake Bosten over the entire Oasis region. For the model, the estimation of the annual evapotranspiration of the area is required. In order to resolve this question, we firstly calculate the water budget with this model by using of some empirical parameters from the previous researching results; then we can compare the calculated lake's levels with the those of recorded for each year. Furthermore, on the basis of the fact that little changes of the water storage in the oasis had occurred for a long period, we can revised the empirical parameters by the means of mathematical analysis to minimize the difference between the water levels of calculated and recorded. Finally, the water level of the lake and other water budgets in the oasis could be calculated with this model, while including the variation of the water storage in the oasis each year.
