摘要
对喀斯特地貌森林中不同小生境的太阳辐射、温度、湿度等进行了多次的观测和研究表明：喀斯特地貌森林中的土面、石面、石沟、石缝，因所处的环境不同，其生态小气候差异明显：土面、石沟的生态小气候条件好，光、热、湿变化缓和，有利于林木生长，而石面、石缝的辐射、温度、湿度变化剧烈，不利于林木的生长。
The solar radiation, temperature and humidity of different microhabitats on karst landform forest were researched and observed. The results showed that the difference of ecologic microclimate was evident for soil surface, stony surface, stong gully and stony crevice. The ecologic microclimate conditions of soil surface and stony gully were very well.The change of light,temperature and humidity were mitigable. It was beneficial to growth of trees. However, the change of solar radiation. temperature and humidity of stony surface and stony crevice were violent. It was not suitable for growth of trees.
