摘要

选取欧亚温带草原东缘生态样带为研究区,根据气象数据和CIMP5气候情景数据,利用Holdridge生命地带 模型对研究区植被类型进行模拟,得到研究区植被格局及未来气候变化下植被格局的空间变化.结果表明:Holdridge 生命地带模型经指标细化,能够很好地模拟研究区植被类型及其空间分布;在RCP2.6情景下,温性典型草原面积减少, 温性荒漠草原面积少量增加,温性草甸草原和泰加林面积增加;在RCP4.5情景下,温性荒漠草原和温性典型草原面积 增加,温性草甸草原和泰加林面积减少;在RCP8.5气候情景下,温性荒漠草原和温性典型草原面积增加,温性草甸草原 和泰加林面积减少.

Abstract

Meadows and woodlands were simulated by the Holdridge life zone model with refined indicators of grassland classification. Ecological Transcets in Eastern Eurasian Temperate Steppe were selected as study area. Meteorological data and CIMP5 climate scenario data were used to simulate vegetation patterns of spatial variation in the study area. The Holdridge life zone simulation was found to simulate vegetation types and their spatial distribution well with refined indicators. In the RCP2.6 scenario, the temperate typical steppe area decreased, temperate desert steppe area increased slightly, the temperate meadow steppe and taiga areas increased. In RCP4.5 scenario, the temperate desert steppe and the temperate typical steppe areas increased, the temperate meadow steppe and taiga areas decreased. In RCP8.5 scenario, temperate desert steppe and the temperate typical steppe areas increased, temperate meadow steppe and taiga areas decreased.
