摘要
以许昌市清潩河岸带植被为研究对象,观测不同植被覆盖下的温度效应,初步得出以下结论:①不同类型植被覆盖的大气温度和土壤温度都表现出明显的"单峰"变化。植被对日温极差变化的缓解作用是通过降低最高温度来实现,对最低温度影响不明显。②林内各垂直高度与大气温度相关密切,并存在明显的梯度效应,随着垂直梯度及层次间距离的增加,相关系数减小。③各类型植被覆盖对温度变化的影响具有动态性和时序性。
This dissertation take the riparian vegetation of the Qingyi River as research object, observed the temperature effect of the different riparian vegetation coverage. And the following conclusion has been deduced: (1) covered by different vegetation, the atmospheric temperature and soil temperature show "single peak" dynamic change obviously. Vegetation can slow down the deviation of the temperature by reducing the maximum temperature, but it has little effect on minimum temperature. (2) The atmospheric temperature has closely related to the vertical height of the woodland, and shown obvious gradient effects. Vary with the vertical gradient and the distance between different levels the coefficient of correlation reduced. (3) All type of Vegetations effect on temperature deviation dynamically and sequentially.
