摘要：分别遴选广州城市尺度上帽峰山、白云山、天河公园样点的常绿阔叶林各0.48、0.48、0.24 hm^2,采用群落生态学的方法对比研究了3种植被类型的群落结构、物种多样性和主要种群间的关联性。结果表明3种植被类型的物种数、林分密度、郁闭度均表现为常绿阔叶天然次生林(EBSF):>常绿阔叶人工-天然混交林(EBANF):>常绿阔叶人工林(EBP);乔木层、灌木层及所有木本植物的Shannon-Wiener指数、Gleason丰富度指数也表现出相同的趋势,且EBSF表现为:灌木层>乔木层,EBANF和EBP表现为:乔木层>灌木层,而Pielou均匀度指数则表现出多变的特征;EBSF、EBANF、EBP的径级结构分别表现为标准、微双峰、多峰的倒"J"型;EBSF与EBANF的20个优势木本植物间整体呈现不显著的正关联,20个优势种构成的190个种对的关联性在χ~2检验、PC值及AC值上均表现出与总体一致的不显著正关联,且EBSF物种间的正关联性更强。结果反映了广州市局部地区常绿阔叶天然次生林、人工-天然混交林、人工林在群落结构、物种多样性以及主要种群间的关联性上的差异,以典型代表整体,旨在为广州近自然林及美丽城镇森林景观的建设及评价提供理论依据。
0.48, 0.48 and 0.24 hm2 evergreen broad-leaf forests of Maofeng Mountain, Baiyun Mountain and Tianhe park in Guangzhou urban scale were selected respectively. Communities structure, species diversity and interspecific association of dominant populations of three vegetation types were comparative studied by the method of community ecology. The result indicated that species number, stand density and canopy density are characterized by Evergreen Broadleaved Secondary Forest (EBSF)>Evergreen Broadleaved Artificial and Natural Forest (EBANF)>Evergreen Broadleaved Plantation (EBP). The same character was showed on the Shannon-Wiener (SW) index and Gleason index of tree layer, shrub layer and all woody plants. The SW index and Gleason index of shrub layer had a higher value than tree layer in EBSF, and it was converse in EBANF and EBP. While the Pielou evenness index showed a changeable feature. The diameter-class structure of EBSF, EBANF and EBP were recognized as Standard, bimodal and peaky inverse“J”type respectively. 20 dominate populations of woody plants showed insignificant positive association in EBSF and EBANF. The interspecific association of 190 species-pairs were the similar conclusion of insignificant positive association analyzed byχ2 correction test, percentage co-occurring (PC) and association coefficient (AC). Moreover, the interspecific association of EBSF species was more significant. The paper revealed the difference in communities structure, species diversity and main interspecific relevance of three vegetation types in Guangzhou local area, which would provide a good theoretical basis for the construction and evaluation of the near-natural forest and beautiful city forest landscape as a typical example.
