Ecological Effects of Typical Urban Greening Plants Releasing Oxygen and Cooling Temperature：A Case Study of Anshun City in Guizhou
In the urban ecosystems,the greening as a subsystem in making beautify the urban environment,it plays an active role of maintaining urban ecological balance and sustainable development.In the paper,Anshun city in Guizhou for a case is studyed by us.On the basis of surveying the green plants in Anshun city urban,the ccological effect of 16 typical plants what releasing oxygen and cooling temperature were studied.The results showed that the plant species less,structure only,species evenness low;the ability of releasing oxygen is different for different plants in different months,but the similar law is rising in June and August,declining in July and September;in August,the law of cooling temperature is consistent with releasing oxygen,but the most obvious were P.acerifolia （0.32℃）,L.quiuoni （0.26℃）,P.trcuspidata （0.46℃） in arbors,shrubs and climbing plants.These results can provide some basis informations and valuable suggestions for the same city ccological construction,improving the living environment and ecologically sustainable development.
