摘要/Abstract

摘要： 为探讨木麻黄林林下物种多样性与土壤因子的相关性,对海口市海岸带不同林分结构的木麻黄林下物种多样性和土壤理化因子进行了调查和分析,结果表明:木麻黄海防林林下群落物种组成简单,有物种约52种,隶属于29科46属;群落物种丰富度指数(S)、Simpson指数(D)及Shannon-Wiener指数(H')均较低,物种丰富度随人为干扰增强而减少;林地土壤含水量极低,有机质、速效钾、速效磷等重要土壤养分极为缺乏。土壤因子与物种多样性的简单相关性研究表明,土壤有机质、速效氮、速效钾含量与多样性指数S、H'和D存在显著的相关关系,初步认为这些因子是影响海口市木麻黄海防林林下物种多样性的重要土壤因子。

Abstract: The understory plant species diversity and soil physical and chemical properties were investigated,and their relationship of the Casuarina equisetifolia coastal protection forest with different stand structure explored in Haikou.Results showed that the understory plant species composition of the Casuarina equisetifolia forest was simple,with 52 species attributed to 29 families and 46 genera.The species richness index(S),Simpson index(D)and Shannon-wiener index(H')were low,and species richness decreased with increase of human disturbance.The soil water content,soil nutrients including organic matter,available potassium and available phosphorus were very low.The results of correlation analysis showed that soil organic matter,available nitrogen and available potassium were significantly correlated with S,H' and D.The strong correlations between soil properties and plant species diversity demonstrate that organic matter,available nitrogen and available potassium are the most important soil factors impacting understory plant species diversity for the Casuarina equisetifolia coastal protective forest.

Key words: Casuarina equisetifolia coastal protective forest, soil property, understory species diversity, correlation analysis
