| 摘 要： | 采用土柱法对黄浦江源区—浙江省安吉县主要植被类型林木细根分布特征进行了研究，结果表明：不同植被类型细根分布有较大差异，茶园、毛竹林、灌木林的根长、根表面积都要明显高于其他几种植被类型，而落阔林的根体积最大，常阔林的根重最大；细根随土层深度的增加而减少，林地细根主要分布在0-40cm土层。草地主要分布在0-30cm土层，这对抵抗径流侵蚀、保持水土资源具有重要意义；各样地根长均以〈0．5mm径级的根长含量最高，0．5-1mm径级次之，而2-5mm径级的最少。根系体积和根重具有相同的分布趋势。大小顺序均为：2—5mm〉1—2mm〉0．5-1mm〉0．5mm，与根长的分布状况正好相反。不同径级根表面积分布差异较大。

| Abstract: | It was studied the root system distribution characteristics of main vegetation types in Anji County of Zhejiang Province by using the horizontal column infiltration method.The result shows that fine roots differed significantly with different vegetation types.Root length and surface area of tea garden,bamboo and shrub community were significantly higher than that of several other vegetation types.Both the root volume of deciduous broadleaved forest and the root weight of evergreen broadleaved forest were be... |
