Furthermore,correlation analysis have been performed between vegetal status measured by canopy density and shelterbelt porosity and TSP removal percentages.
通过对上海浦东某交通干道旁侧绿化带不同季节大气中总悬浮颗粒物(TSP)的测定,定量研究了绿化带对TSP的净化效益;同时对研究区域内植物的配置情况用郁闭度和疏透度进行了表征,并研究了其与TSP的净化效益之间的相关性。
The windbreak models used in this study have porosity of 0%,30%,40%,60%respectively.
实验中选用的防护林疏透度分别为0%,30%,40%,60%。
