| 摘 要： | 运用对比研究方法,于1982～1990年,对田林老山常绿落叶阔叶混交林及草坡地的主要气象和水文要素进行了定位观测研究,并对所得的数据进行了统计回归分析。结果表明,常绿落叶阔叶混交林在减缓气温和地温振幅,提高空气湿度,减少物理蒸发等方面具有极显著的气候生态效应;对大气降雨量具有截留、再分配,消减地表径流,防止土壤冲刷,水源涵养等良好的水文效应。研究结果说明,常绿落叶阔叶混交林在维护山地中海拔生态平衡中具有重要的作用。

| Abstract: | A comparative inves0igation on meteorological and hydrological factors of the evergreen and deciduous broad-leaved mixed forest as well as grass glade in Laoshan Mountian, Tianlin, was carried out from 1982 to 1990. The data were analysed with regression method. The results show that the evergreen and deciduous broad-leaved mixed forest has highly remarkable climate-ecological effects in decreasing the amplitudes of air temperature and soil temperature, increasing the relative humidity as well as reducing the physical evaporation, etc. It aiso has obvious hydroecologic effects in interception of rainfall, redistribution of precipitation, reduction of surface runoff, and prevention of soil erosion as well as conservation of water supply, and so on, indicating that the evergreen and deciduous broad-leaved mixed forest is advantageous to keep the ecological bliance in this region. |
