摘　　要：通过分析阿尔山市近50年年平均气温及年降水量变化,评估该地区植物气候生产力(TSPV)的年代际变化及未来气候变化情景下变化趋势。本文应用Thornthwaite Memorial模型,计算植物气候生产力对年均气温和降水量变化的响应情况。研究结果表明:(1)该区增温率为0.35℃/10a,降水呈弱减趋势,减少率为5.64 mm/10a;(2)近50年阿尔上市TSPV变化缓慢,表现为不显著的增加趋势;(3)“冷湿型”“暖干型”气候类型都出现TSPV正负距平现象,说明气温和降水不是该地区植物气候生产力变化的唯一限制因子;(4)TSPV增减与年平均气温和降水变化同步,其中降水变化对TSPV的影响大于气温变化的影响。Through the analysis of Alshancity nearly 50 years average temperatures and Annual precipitation change,evaluate the climate productivity of Alshan cityinterannual and interdecadal change and the future climate change scenarios trend.The paper using Thornthwaite Memorial model Calculation the climate productivity change response to annual temperature and rainfall changes.The result indicated that The rate of warming of Alshan was 0.35℃/10 a,rainfall is weak decreasing trend,decrement rate was5.64 mm/10a;the TSPV of Alshan changes slowly,appear weak increase trend in The last 50 years;“Cold-wet”and“warm-dry”climate TSPV all appear positive and negative anomaly phenomenon,the result show that the temperature and precipitation is not the only limit factor to Alshan TSPV change;the TSPV increase or decrease synchronization with the temperature and precipitation change,the precipitation change influence TSPV value changes greater than the temperature effects.
