| 摘 要： | 根据兹格塘错流域附近气象站（安多，那曲和班戈）的器测资料和那曲站的实测辐射资料，对兹格塘错水面蒸发进行了估算，结果表明，兹格塘错多年平均（1958－1998年）蒸发量为925．1mm，在估算的41年中，最高的为1111．5mm(1975年），最低的仅791．9mm(1983年），5年滑动平均结果揭示，近40年来兹格塘错蒸发存在波动变化，基本上由2个峰值期（1970－1980年和1993－1998年），1 个下降期（1975－1980年）和2个相对平衡期组成，且总体上呈上升趋势。

| Abstract: | Zige Tangco (32°00'-32°09'N, 90°44'-90°57'E, 4560a.s.l.), located in Central Qinghai-Tibetan Plateau, is an endo rheic saline lake.As no instrumental data were available in the basin, three nearby stations, i. e. Amdo, Naqu and Bangoin, were selected for lake evaporation estimates in Zige Tangco.Meteorological observations from three above-mentioned stations as well as radiation data from Naqu were used for Penman equations approach.During 1958-1998, a yearly-mean lake evapo ration of 925.1mm was calculated, ranging from 791.9mm (in 1983) to a maximum 1111.5mm (in 1975).Further 5-year running average resuls revealed that 2 high-level stages and 1 low-level stage were dominant in the past 40 years, and an ascending trend was obvious, though fluctuating. |
