黄河小浪底库区不同恢复阶段群落小气候特征研究

采用“空间代替时间”的方法,对小浪底库区不同恢复阶段群落的小气候特征进行研究.研究表明,随着植被恢复时间增加,太阳辐射、土壤温度、气温及其变动幅度逐渐减小,大气相对湿度逐渐升高;随着恢复演替阶段的上升,群落小气候逐渐得到改善;对不同恢复阶段小气候要素进行回归分析,发现大多数裸地气象要素与各恢复阶段群落气象要素之间存在显著的相关关系,以气温和相对湿度的相关性最好.

Community Microclimate Characteristics at Different Vegetation Restoration Stages of Xiaolangdi Reservoir on the Yellow River

Using"the method of replacing time with space",the microclimate variation of the vegetation at different community restoration stages in Xiaolangdi was studied,the results showed that the radiate intensity,soil temperature,air temperature and their fluctuation declined with the development of vegetation restoration.But the relative air humidity increased.With the development of community restoration stages,the community microclimate was gradually improved.Using the regression analysis of microclimatic elements at different restoration community stages,we learn that there is a significant correlation between most microclimatic elements.Meanwhile,the correlation between air temperature and relative humility is significant one.
