摘要
对厦门山地常见4种林型的物种多样性、土壤肥力和涵养水源功能进行了分析研究,以探索不同林地类型涵养水源能力。结果表明:常绿阔叶林、落叶阔叶林和针阔叶混交林的Shannon-Winner指数相对较高,而且能增加土壤有机质和N、P、K含量,改善土壤养分状况;针叶疏残林能提高土壤有效P的含量;各林型的枯落物吸水量大小依次是:针阔叶混交林(18.193t/hm^2)>落叶阔叶林、(8.936t/hm^2)>常绿阔叶林(4.113t/hm^2)>针叶疏残林(4.004t/hm^2);将土壤非毛管孔隙度大小作为判断和计算土壤蓄水量的基本标准,则土壤持水量大小依次是落叶阔叶林、针阔叶混交林、针叶疏残林和常绿阔叶林。
Species diversity,soil fertility and water conserving capacity of four forest sloping lands were analyzed in Xiamen.The results showed that Shannon-Winner index,soil organic matter and content of nitrogen,phosphorus,and potassium and soil fertilities were higher in evergreen broad-leaved forest（EBF）,deciduous broad-leaved forest（DBF）and needle and broad-leaved mixed forest（NBMF）than that in needle leaves forest（NLF）.Content of plsen phosphorus in NLF was higher than that in EBF,DBF and NBMF.The amount of litter and the water absorption capacity were in order of NBMF（18.193t/hm^2） DBF（8.936t/hm^2） EBF（4.113t/hm^2） NLF（4.004t/hm^2）.The water holding capacity was in order of DBFNBMFNLFEBF considering non-capillary porosity.
