| 摘 要： | 以赣中毛竹纯林(MC)、竹阔混交林(ZK)、竹杉混交林(ZS)3种不同类型毛竹林地土壤容重、孔隙状况、团聚体数量、大小和稳定性等土壤结构特征进行了研究,同时以阔叶林(KY)和杉木纯林(SC)为对照,并采用灰色关联度分析法进行了土壤结构综合评价。结果表明,各林分土壤容重大小排序为ZK>MC>ZS>KY>SC;土壤孔隙状况总体表现为阔叶林优于杉木林,毛竹林类型较差;>0.25 mm土壤团聚体含量在94.43%～97.25%,土壤各层均为阔叶林最大;土壤团聚体分形维数均值大小排序为MC>ZK>ZS>SC>KY;不同林分类型间土壤MWD和GMD存在差异,与毛竹纯林比较,竹阔和竹杉混交林0～60 cm土层中土壤MWD和GMD均值分别提高了3.38%、4.10%和5.04%、8.11%;灰色关联度分析法的结果表明,各林分类型土壤结构指标关联度大小排序为KY>SC>ZK>ZS>MC,研究结果可为我国亚热带地区林地资源合理经营及植被建设提供科学依据。

| Abstract: | Five kinds of stand type（Pure Moso bamboo forest,mixed forest of Moso bamboo and broad-leaved tree,mixed forest of Moso bamboo and Chinese fir,broad-leaved forest,Chinese fir pure forest） had been chosen at Anfu,Jiangxi province.Through the study on soil structural characteristics,such as soil bulk density,soil porosity condition,and content,size,stability of soil aggregate were exposed.Finally,soil structural was comprehensive evaluated by grey correlation degree analysis.The results showed that the order of soil bulk density was mixed forest of Moso bamboo and broad-leaved forest 〉 pure Moso bamboo forest〉mixed forest of Moso bamboo and Chinese fir 〉 broad-leaved forest 〉 Chinese fir pure forest;soil porosity condition manifested as broadleaf forest is superior to Chinese fir pure forest,Moso bamboo forest is relatively poor.〉0.25 mm soil aggregates content from 94.43% to 97.25%,broadleaf forest were the largest in all soil layers.The order of soil aggregates fractal dimension mean was pure Moso bamboo forest 〉 mixed forest of Moso bamboo and broad-leaved tree 〉 mixed forest of Moso bamboo and Chinese fir 〉 Chinese fir pure forest 〉 broad-leaved forest.The soil MWD and GMD of different stand types were difference.The soil MWD and GMD mean of mixed forest of Moso bamboo and broad-leaved forest and mixed forest of Moso bamboo and Chinese fir were increased by 3.38%,4.10% and 5.04%,8.11%,respectively.The order of index grey correlation degree of soil structure were broad-leaved forest 〉 Chinese fir pure forest 〉 mixed forest of Moso bamboo and broad-leaved forest〉 mixed forest of Moso bamboo and Chinese fir 〉 pure Moso bamboo forest by grey correlation degree analysis.The results could provide some scientific basis for forest resources management and vegetation construction in the subtropical region of China. |
