摘　　要：选取2000-2015年气象站点及MODIS NDVI数据进行长时间分析,以评估气候变化对我国特有珍稀两栖物种安吉小鲵生境的影响.结果表明:保护区内气温、降水均有增加趋势,增幅分别为0.007~0.017℃/a、21.5mm/a,区域小气候表现为暖湿化进程;NDVI在近16年有下降趋势,每年减幅0.000 3.气候的暖湿化使保护区内泥炭沼泽植被群落生长呈减缓趋势,导致安吉小鲵生存空间压缩,进而影响种群生长繁殖.In this study,meteorological stations and MODIS NDVI data from 2000 to 2015 were analyzed to evaluate the effects of climate changes on the habitat of Hynobius amjiensis National Reserve.The results showed that the temperature and precipitation had an increasing trend,with an increase of 0.007-0.017 ℃/a and 21.5 mm/a,respectively,showing a process of warming and humidification.NDVI had a downward trend in the past 16 years,with a decrease of 0.000 3 per year.It was pointed out that the warming and humidification trend of local climatic conditions slowed down the growth of peat bog vegetation communities in the protected area,resulting in the living space compression of Hynobius amjiensis,which in turn affected the population growth and reproduction.
