徐州市故黄河滨水绿地乔—灌—草型、乔—草型植物配植的环境效应分析

Analysis on the Plant Arrangement and Environmental Effect of Arbor-Shrub-Herb Type,Arbor-Herb Type Riverside Green of the Old Yellow River in Xuzhou

针对徐州故黄河的乔—灌—草型、乔—草型等结构类型的典型配置模式进行了试验分析,测得了各不同配置模式下的温度、湿度、光照强度和CO_2吸收率,并与同时在学校的对照组进行了对比,结果表明:绿地中的两种植物配置模式中,乔—灌—草型类型对温湿度的改善作用较大,起到降温增湿的效果,具有较好的生态效益。绿地CO_2吸收率的大小与植物种类密切相关。故黄河试验组的各环境效应指标值均优于学校对照组,说明古黄河水系对环境起到改善作用。

Based on the old Yellow River of Xuzhou reason-irrigation grass-Joe,Joe-grass type structure types of typical configuration model test,this paper analyzedthe different configuration mode of temperature,humidity,light intensity and CO_2 absorption rate.Compared with the control group at the same time,it can be seen that in the two plant allocation modes in the green space,the type of Qiao-irrigation-grass has a greater effect on the improvement of temperature and humidity with effect of cooling and humidifying and good ecological benefits.The amount of CO_2 uptake in green areas is closely related to plant species.The environmental impact index values of the Yellow floor group were better than those of the school control group,which indicates that the Guhuang River water system improved the environment.
