摘要：全球气候变化背景下,植被与气候相关关系已经成为研究热点,森林水热环境决定于区域水热条件,并受气候变化的综合影响。海南尖峰岭热带森林是中国典型的热带森林生态系统之一,研究该林区长期气候变化特征对评价热带森林对全球气候变化的响应与适应具有重要意义。利用海南尖峰岭森林生态系统国家野外科学观测研究站尖峰气象观测场1957-2003年的林外地面常规气象观测资料,选用气候趋势系数和气候倾向率定量分析尖峰岭林区光、水和风等气候因子的变化趋势,结果表明:47年间,尖峰岭林区年日照时数、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2056.5 h、1659.4 mm、1725.6 mm、81.68%、25.49 hPa、1.66 m·s^(-1)。年降水量、相对湿度、水汽压均呈上升趋势,其中相对湿度和水汽压升高趋势显著(P<0.05),每10年分别增加0.75%和0.38 hPa;日照时数、年蒸发量和年平均风速均呈显著下降趋势(P<0.05),每10年分别减小101.6 h、126.9 mm和0.37 m·s^(-1);月降水量年变化趋势均不显著,而月蒸发量除1月和3月外,其余月份的蒸发量年际变化均呈现显著降低趋势。林区主要来风方向为正北方向。年降水量与年蒸发量的比值约为1.0,表明尖峰岭林区从长期来看处于水分平衡状态。气候增暖作用分析表明尖峰岭林区气候增暖作用显著,呈现出对全球气候变暖的明显响应特征。
Underground of climate change, many scientists focused on the relationship between vegetation and climate change. Tropical forest in Jianfengling (JFL), Hainan Island is one of the typical tropical forest ecosystems in China. Its long term climatic dynamics is important for global change research. Some climatic factors, such as radiation, humidity and wind, were analyzed based on the meteorological data recorded for the area by the Opened Research Station of Tropical Forest Ecosystem in JFL during the period from 1957 to 2003. The results showed that average annual sunshine hours, precipitation, evaporation, relative humidity, vapor and wind speed was 2 056.5 h, 1 659.4 mm, 1 725.6 mm, 81.68%, 25.49 hpa, 1.66 m·s-1, respectively. Annual relative humidity, and annual mean vapor pressure increased significantly (P<0.05), having an increase of 0.75% and 0.38 hpa per 10 year. Annual precipitation exhibited an increasing trend, though an obvious decrease in annual sunshine hours, annual evaporation and mean wind speed were recorded (P<0.05), having a decrease of 101.6 h, 126.9 mm and 0.37 m·s-1. The increasing trends of monthly precipitation were not significant, but the decreasing trends of monthly evaporation were significant (P<0.05), except in January and March. The predominant wind direction was due north. The ratio of annual precipitation and evaporation is near to 1.0, it means that water cycle existed balance situation in JFL tropical forest from a long period. Climate warming effect reveals that under global change, there was climate warming process occurring in the JFL tropical forest.
