艾比湖湿地调节气候生态服务价值评价

Valuation of the Ecological Service of Regulating Climate of Ebinur-Lake Wetland

增湿调温的气候调节功能是湿地重要的生态功能。位于干旱区的湿地,其增湿调温功能尤为明显。湿地自由水面巨大的水汽蒸发及湿地茂密植被剧烈的水汽蒸腾,是其增湿调温、调节气候的主要物质基础。通过计算艾比湖湿地年水汽蒸发、蒸腾量,得出其每年调节气候的生态服务价值为97788.86×104元,占艾比湖湿地总生态服务价值的31.9%,位居研究区各项生态价值之首。结果表明,增湿调温的气候调节功能是处于极端干旱地理条件下的艾比湖湿地最重要的生态服务功能。

An important ecological function of wetland is to increase air humidity and to cool down air temperature. This is particularly evident for the wetland in arid areas. The large amount of evaporation from the water surface and the strong transpiration from the dense vegetation cover of the wetland are the major causes for this climatic buffering function. By calculating the annual evaporation and transpiration of the Ebinur lake wetland, the annual cost of ecological service of climatic buffering was estimated at 97 788.86 × 10^4 , accounting for 31.9% of the total value of the ecological services and the largest among other ecological services of the wetland. Results indicated that the function of climatic buffering if the most important ecological function of Ebinur lake wetland in extremely draught conditions.
