摘要: 用西双版纳6个气象站40余年观测资料,探讨中国内陆热带地区气候变化特征及趋势。结果表明:西双版纳地区的平均气温、平均最低气温、平均最高气温总体上呈逐年增暖的趋势,其中平均气温上升率0.016 5~0.033 4℃/a,平均最低气温上升率0.008 6~0.038 7℃/a,平均最高气温上升率-0.001 4~0.018 6℃/a;降水长期变化特征则较复杂,规律不如气温明显,但总体趋势减少,年降水量变化主要决定于雨季降水量变化;相对湿度呈现逐年降低趋势。说明该地区气候向干热型转变。

Abstract: Up to now,studies on climate change are,more and often,concerned with global or national scale.It is noted that the climate change is not globally uniform.Regional variations can be much larger and considerable spatial and temporal variations may exist between climatically different regions.The climate of a specified location can not be considered a constant environmental factor.In addition,a climate change in a specific region or nation is of particular interest to that region and its economic activity.The aim of this paper is to present a responsibility of a region to global change by studying climate characteristics and change trends of a specific region,the tropical area of southwestern China.Based on long-term meteorological data of 6 meteorological stations in Xishuangbanna of Yunnan Province,the spatial and temporal distribution of change trend for temperature and precipitation are studied.The results show that the general trend of climate change in Xishuangbanna is basically the same with that in China and even in the world.The mean annual air temperature has been gradually increasing,and with an average trend of 0.0165-0.0334 ℃/a.Meanwhile,there are some differences on increasing rate between the mean maximum and mean minimum temperature.The annual precipitation changes complicatedly with an entire decreasing trend.The air relative humidity presents an obvious decreasing trend.In addition,the climate change trends show the differences that exist in the various regions and the notable seasonal variations,and the temporal and spatial distribution of climate characteristics and change amplitude is different in different regions.
