为探索和估算我国森林碳汇功能提供准确和可靠的基础数据,利用江西省森林资源二类清查资料,运用材积源生物量法对江西省森林碳储量和碳密度进行了研究。森林植被乔木层碳密度的特征为,全省不同森林类型碳密度由大到小依次为硬阔林、针阔混交林、毛竹林、国外松林、杉木林、软阔林、灌木林、马尾松林和经济林;乔木层碳密度随着林龄的增加而增大,随着人口密度的增加而降低。不同森林碳储量由大到小依次为杉木林、马尾松林、硬阔林、灌木林、经济林、毛竹林、针阔混交林、国外松林和软阔林,全省南部和中西部要高于中东部和北部。江西省森林总碳储量为1.5G t C,占全国森林总碳储量的5.33%。

A female Brown-fronted Woodpecker (Dendrocopos auriceps) was first observed and photographed in the Jilong Valley of the Mount Qomolangma Region,China,on 21 May *** coordinates of the site are 28°19′25.03″N,85°20′29.70"E at an elevation of 2150 m.A few months later,a male was observed at 28°20′02.49"N,85°20′46.30"E on 8 August at an elevation of 2197 *** habitat is a mountain temperate coniferous and dry broadleaved mixed forest of the warm temperate zone.
