摘要:
全球气候变暖已成不争的事实,区域气候条件的变化必然对该区域的植物生长与繁殖等多方面产生很大的影响。通过分析西双版纳热带植物园内热量条件(包括气温与地表温)1959—2008年间变化特征,讨论其对植物园中热带植物的影响。研究表明:西双版纳年平均气温与地温分别以0.013和0.007 ℃/a的速率上升,相对全国较缓;同时,热量因子年间变异程度及极端温度出现的程度均呈下降趋势。西双版纳热带北缘的特殊地理位置决定其热量相对于典型的热带地区不足,因此变暖的气候条件将有利于这里热带植物的生长与繁殖。但由热量变化可能导致的其他环境因子的变化(如降雨量减少等)则可能对植物生长与繁殖产生不良影响。
Abstract:
In this study, we used the longterm data (1959-2008) of air temperature and soil surface temperature in Xishuangbanna Tropical Botanical Garden to investigate the interannual trends of the heat condition and discuss the influences on the tropical plants. The results showed that air temperature and soil temperature both exhibit an annual increasing rate of 0.013 and 0.007 ℃/a, respectively. The rates are lower than the average level in China. The interannual variation and extreme extent for air temperature and soil temperature both showed trends of decrease. As the temperature in Xishuangbanna is lower than other tropical regions near equator, the heat condition can definitely favor the tropical plants in the botanical garden. However, due to heat factor change, decreasing precipitation and other aspects might negatively affect the plants on growth and reproduction.
