宜昌市城区不同绿地类型环境效应

Environmental Effects of Different Greenbelt Types in Yichang

选取宜昌市 5个具典型代表性的绿地类型 ,以水泥垫面作为对照 ,同步监测了包括地表温度、最高最低气温、辐射热、噪音、大气粉尘含量等环境指标。研究结果表明 :城市绿地类型环境效应与其空间结构、绿量大小有密切关系 ,具乔、灌、草垂直结构的绿地类型环境效应最佳 ,而结构单一、绿量含量小的草坪类型对环境质量改善程度有限 ,环境效应相对较差。

Using concrete land as contrast, an experiment was conducted to synchronously observe land temperature, the highest and lowest temperatures, radiant heat, noises, content of atmosphere dusts at five typical greenbelts in Yichang. The result shows that the effect of green entity in cities has close relationship with its spatial structure and volume. The greenbelt with arbor-shrub-grass vertical structure has the best environmental effect, while the environmental effect of grassland with simple structure and less green entity is relatively weak.
