crown closure measurement in aerial photo

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 main factor of green belt hindering the gaseous pollutants diffusion was the canopy density and not the vegetation quantities.

以CO为环境示踪物,通过对西安市典型街道的实测和数据分析,讨论了绿化形式对街道污染物扩散效果的影响,指出绿化带对气态污染物扩散存在阻碍作用的因素是郁闭度,而不是绿量,车流量的大小对行道树树冠的生态净化功能有直接影响,并据此对街道绿化的生态设计给出了建议。

koreanumwhen the factors of planting density,canopy density and using fertilizer were changed.

以产量为指标,以种植密度、郁闭度及使用肥料为影响因素,采用正交试验法,探讨朝鲜淫羊藿于阔叶林下仿生栽培的最佳技术措施。
