Environmental Factor Characteristics of Secondary Betula platphylla Forest at Different Succession Stages in Changbai Mountain
摘要
Abstract
On the basis of environment factor monitoring in the field survey,the variation of environmental factors of secondary Betula platphylla forest at different succession stages is analyzed in Changbai Mountain. The results show that the community succession is the main factor for the changes of environmental factor index. The air temperature,the daily amplitude of air temperature,the daily amplitude of relative humidity decreased along with the community succession. Photosynthetically active intensity and relative humidity increased along with the community succession. Soil temperature and humidity change irregularly with community succession. Rate of change(vav)can obviously reflect variation of the environmental factor with the community succession,we can conclude the sensibility of environment factor in the process of community succession by comparing the rate of chang. Photosynthetically active radiation>the soil temperature at the depth of 5 cm >the diumal amplitude of relative humidity> the soil humidity at the depth of 10 cm > the diumal amplitude of air temperature>relative humidity>air temperature inside forest>the soil temperature at the depth of 20 cm >the soil temperature at the depth of 10 cm.关键词
