Microclimate Environment Characteristics at the Rainforest Garden of Qingxiu Mountain in Nanning
In order to fully understand the microclimate characteristics at the Rainforest Grand of Nanning Qingxiu Mountain,we investigate the different locations of the rainforest at different time periods and with different community composition,and measure the negative ion concentration,temperature and humidity,for analyzing the characteristics of microclimate environment.The results show that the microclimate environmental quality is ordered:forest＞proximity to water＞square for locations,morning＞afternoon＞noon for time period,and herbaceous plants＞shrub＞arbor＞pavement for community composition.The microclimate environment of the understory herbaceous layer is better than other layers,with better ecological benefits.The microclimate environment of square pavement,arbors in square,shrubs in square and waterside pavement is relatively poor.Temperature and humidity have significant linear correlation with the concentration of negative ions,which are also the important influencing factors to negative ions concentration.Hence,it is suggested that the Rainforest Garden should be improved from the three aspects:1)More spaces for recreation and leisure should be designated under forests;2)Activities such as science popularization should be held in the morning when the microclimate environment is the best;3)More attention should be paid to the reestablishment of plant communities to promote the ecological cycle of micro-environment through the improvement of plant diversity.
