泉州市居住小区植被三维绿量及生态效益价值

Three-Dimensional Green Biomass and Eco-Efficiency Value of Vegetation in Residential Quarters of Quanzhou City

以泉州市居住小区为研究对象,调查7个居住小区的三维绿量,分析群落总三维绿量与植物群落结构特征之间的关联性。结果表明,泉州市居住小区植物群落(400 m^(2))总三维绿量为53.39~231.27 m^(3)。多元线性回归分析揭示,乔木层平均高度和Shannon多样性是影响群落总三维绿量的主要群落结构特征。可通过提高乔木层平均高度和Shannon多样性,提升居住小区植被的三维绿量及其生态效益价值,改善城市人居环境。

The three-dimensional green biomass of vegetation in seven residential quarters of Quanzhou was measured,and the relationships between total three-dimensional green biomass and the characteristics of plant communities were analyzed.It was found that the total three-dimensional green biomass of the plant communities in an area of 400 m^(2)ranged from 53.39-231.27 m^(3).A multiple linear regression analysis revealed that the average height and the Shannon diversity index were the determinants affecting the total three-dimensional green biomass.The eco-efficiency value and three-dimensional green biomass can be improved by increasing the average height of the arbor layer and boosting Shannon diversity of plant communities in order to enhance the urban human settlements.
