不同绿地空气负离子比较研究——以浙江富阳市洞桥镇为例

空气负离子是衡量空气质量的重要指标之一,试验测定富阳市洞桥镇不同绿地空气负离子浓度,研究其生态效应变化。结果表明,以高大乔木为主的城郊绿地空气负离子浓度较高,生态效应显著。因此,植物景观设计上要遵循近自然森林群落理念,注重以高大乔木为主的森林绿地建设,改善城镇生态环境质量,提高城镇生活品质。

The Comparison of Air Negative Ion of Different Green land in Dongqiao Township

Air negative ion is one of important index reflecting the air quality. This paper has measured the air negative ionconcentrations of different green lands in Dongqiaotownship, and studied its ecological change. The results showed that there were higher concentration of air negative ion and more obvious ecological effect in the suburb green land full of high woody plants. Therefore, theidea of closing to natural forest community must be followed on the side of plant landscape design, and forest green land composed of high woodyplants ought to be constructed in order to improve ecological environmental quality and raise life quality in township.
