摘要: 为探讨绿化树种量化选择方法,观测计算郑州市常见的16 个乔木树种年生长量、固碳释氧量、固土保肥量、涵养水源量、积累营养量与净化空气功能及其价值,采用聚类与主成分分析法,对不同树种的生态服务价值进行了分析。结果表明:生态价值较高的树种为银杏(Ginkgo biloba)、悬铃木(Platanus acerifolia)、白蜡(Fraxinus chinensis)、国槐(Sophora japonica)与枇杷(Eriobotrya japonica);生态服务价值较低的树种为黄山栾(Koelreuteria bipinnata)、女贞(Ligustrum lucidum)、雪松(Cedrus deodara)、圆柏(Sabina chinensis)与侧柏(Platycladus orientalis);其他树种生态服务价值中等。建议在造林绿化中优先选择生态 服务价值较高的树种。

Abstract: The paper aims to explore the quantitative selection method of green tree species. Sixteen common tree species were selected as the research materials in Zhengzhou, the growth and value of carbon fixation and oxygen release, soil reinforcement and fertility maintenance, water conservation, nutrient accumulation and air purification of these tree species were calculated. Then cluster analysis and principal component analysis were used to examine ecological service value. The results showed that Ginkgo biloba had the highest carbon sequestration content, followed by Platanus acerifolia, Fraxinus chinensis, Sophora japonica, Eriobotrya japonica; Koelreuteria bipinnata, Ligustrum lucidum, Cedrus deodara, Sabina chinensis and Platycladus orientalis had the lowest ecological service value; the other trees had medium ecological service value. The tree species with higher ecological service value are recommended for afforestation in Zhengzhou.
