摘要:
为量化泉州市公园植物群落结构的三维绿量及生态效益,选取泉州市的刺桐公园、中山公园和东湖公园的24个植物群落作为研究样地,测量每个样地的植物群落结构特征与三维绿量,拟合三维绿量的影响因素,以提高群落的总三维绿量。结果表明:24块植物群落有61种植物,植物群落结构以乔灌草的复层结构为主,群落的均匀度和稳定性相对较高。群落的总三维绿量为21.46~216.56 m3,群落间三维绿量差异很大。由线性逐步回归结果可知:乔木层高度、盖度及复层数是群落总三维绿量的重要影响因素,决定系数R2为0.689。因此,建议从提高乔木层高度、盖度及复层数调整植物群落的结构特征,以提高三维绿量,从而实现提高生态效益的目的。
Abstract:
In order to quantify tridimensional green biomass and ecological benefits of plant community structures in urban parks, 24 plant communities in the Citong Park, Sun Yat-sen Park and the East Lake Park in Quanzhou City were selected as sample plots. Each plant community structure and its tridimensional green biomass were measured to seek influence factors with fitting. It was found that there are 61 plants in 24 plant communities, and that their plant community structures are dominated by a multistrata structure of trees, shrubs and grasses with relatively high evenness and stability. Their total tridimensional green biomass was 21.46-216.56 m3 with sharp inter-community differences The linear stepwise regression results showed that the height of the tree strata, coverages and the number of strata are the important factors of total tridimensional green biomass of a community with a coefficient of determination R2 of 0.689. Therefore, it was suggested that the structural characteristics of a plant community can be adjusted from height, coverage and the number of strata so as to improve the tridimensional green biomass in the interest of improving the ecological benefit.
