摘要
通过样方调查将福州沙滩公园木本植物群落划分为8种类型,应用生态学方法计算24个群落的特征值和群落三维绿量,通过逐步回归分析各群落特征值与群落三维绿量的关系,确定影响群落三维绿量的主要因素。结果表明,群落乔木层平均冠高、优势种平均树高、乔木层平均胸径和Shannon-Winner多样性指数是影响三维绿量的主要因子。另外,公园中的8种人工群落乔灌层结构不尽合理,层次不够明显,公园绿化的植物种类较单一,物种丰富度较低。
Woody plant communities in the Fuzhou Beach Park were categorized into 8 types through sampling and 24 structural characteristics and tridimensional green biomass in plant communities were investigated with ecological method to determined the influencing factors which influence the tridimensional green biomass by regression analysis of the relationship between the structural characteristics and the tridimensional green biomass of various communities. The result of regression showed that the average crown height, the average height of dominant species, the average of diameter at breast height, and Shannon-winner index are the main influencing factors. Besides, the structure of the 8 types of trees and shrubs was not reasonable with unclear layers. The species richness of the plant communities was lew and lack of variations.
