佛山城市绿地系统环境效益的研究

Preliminary study of the environmental effect of urban green area system in Foshan

选取佛山代表公园绿地、生产绿地、防护绿地和附属绿地等绿地系统作为研究对象,对其系统中的环境效益进行了研究。研究表明,各类绿地系统均具有减少噪声、降低温度、吸收CO2、增加湿度、吸收有害气体、净化环境等功能,并从环境效益的角度,提出了适当的栽种密度、常绿阔叶植物有利于充分发挥绿地系统的环境效益功能等建议。

Some green space systems such as park greenbelt, production greenbelt, shelter greenbelt and attached greenbelt were selected to study the environmental effect of them. The results show that all sorts of green area systems can decrease noise dBs and temperature, absorb carbon dioxide, increase humidity, absorb pollutants to improve air quality. Based on the environment effect, the measures are put forward such as suitable density of planting and evergreen broadleaf plants helping reinforce the capacity of purifying environment of green area .
