摘要 通过对苏北山丘区6种代表性森林群落枯落物现存量、吸纳重金属、养分贮存能力和蓄水固土等生态功能的研究,结果表明:6种代表性森林群落枯枝落叶层现存量、对氮的贮存能力以及最大拦蓄量均以栎类林群落最大;对磷和5种重金属的贮存量以侧柏林群落最大,栎类林群落次之;赤松林、黑松林和刺槐林群落的各项生态功能相对较弱。 A study was carried out on ecological functions of forest floor,such as standing stock of litter,detainment of heavy metals,nutrient storage ability and water holding capacity of six typical forest communities in the hilly region of northern Jiangsu Province.The results show that with regard to standing stock of litter,for N storage capacity and the water holding capacity of forest floor,the Quercus community is the highest among the six forest communities,while as far as P and five heavy metals storage capacity is concerned,the Platycladus orientails forest community is the highest and followed by the Quercus.By comparison,the Pinus densiflora and Pinus thunbergli forest and Robinia pseudoacacia forest community are inferior in all these aspects.
