摘要：采用海南尖峰岭森林生态系统国家野外科学观测研究站天池气象站1980～2005年的地面常规气象观测资料,分析了光、水和风等气候因子的变化趋势,结果发现:26年来,尖峰岭热带山地雨林区年日照时数、年降水量、年蒸发量、年平均相对湿度、年平均水汽压和年平均风速的多年平均值分别为1467.4h、2449.0mm、1248.8mm、88.67%、20.77hPa、1.2m/s。年降水量、平均相对湿度、平均水汽压均呈上升趋势,其中平均水汽压升高趋势明显,每10a增加0.38hPa;日照时数、年蒸发量和年平均风速呈下降趋势,其中平均风速下降明显,每10a减小0.27m/s;月降水量和月蒸发量年代际变化规律不一,但10月份的降水量和9月份的蒸发量下降趋势明显。气候增暖作用分析表明,在全球气候变化背景下,尖峰岭山地雨林区气候增暖作用显著。
Jianfengling tropical mountain rainforest in Hainan is one of the typical tropical forest ecosystems. Its long term climatic dynamics is important for global change research. Some climatic factors, such as radiation, moisture and wind, were analyzed in light of the meteorological data recorded for the area by the Opened Research Station of Jianfengling Tropical Forest Ecosystem. The present study critically analyzed the dynamic characteristics of these climatic factors over a period of 26 years. The results showed that, the precipitation, mean relative humidity and mean vapor pressure on annual basis have been rising in the past 26 years over the Jianfengling forest. Annual mean vapor pressure increased significantly and annual sunshine hours, evaporation and mean wind speed also exhibited an ascending trend, though an obvious decrease in the wind speed was recorded. While the yearly changes of monthly precipitation and evaporation fluctuatecd irregularly, the monthly precipitation in October and evaporation in effect reveals that under global change, there was climate warming rainforest. September showed a decreasing trend. Climate warming process occurring in the Jianfengling tropical mountain rainforest.
