中文摘要 城市森林群落的景观及环境生态效应日益受到人们的重视,采用群落生态学结合对比观测研究方法,研究了广州城市小尺度(水平23 km)间隔的天河公园、白云山及帽峰山森林群落的生态特征及其关系,结果反映出:3区位的森林群落优势种群明显且生态位宽度较大,种属比分别为86.8%、82.4%和90.0%,每区物种的异质性较高;帽峰山与白云山、天河公园森林群落的物种相似度分别为35.3%、10.1%,前二者的林分密度间无显著差异、均与后者间呈极显著差异(p=0.006,0.0002);前两者的乔灌木径高比呈极显著差异(p=0.0018),后两者则呈显著差异(p=0.02);各区的乔灌木密度随径高比递增呈极显著的负对数递减关系,3个区森林冠直径与径高比间依次呈对数、指数及对数回归关系,为各类森林景观的定向经营提供了调控依据;帽峰山森林乔灌木的多样性指数最大达3.8±0.65、天河公园则为最小(3.03±0.37),两者呈极显著差异(p=0.00016);该研究为城市与近郊森林植被的多样性保护提供了依据。

英文摘要 Ecological landscape and environmental effects of urban forest communities have attracted increasing attention worldwide. Integrating methodologies of community ecology and comparative monitoring, the present study detected ecological characteristics and possible correlations of three fine-scale (ca. 23 kmby radius) landscape forest communities in Guangzhou city, specifically Tianhe forest park (TFP), Baiyunshan forest park (BFP), and Maofengshan forest park (MFP). The results showed that dominant species were common and ecological niches were relatively broad in these three forest communities. High heterogeneity was observed and genus-species ratios were 86.8%, 82.4% and 90.0% respectively. Species similarities of MFP-BFP and MFP-TFP were 35.3% and 10.1%. No significant difference of stand density was detected between MFP and BFP, while a significant difference was detected between MFP and TFP (p=0.006), BFP and TFP (p=0.0002). Furthermore, a significant difference of diameter-height ratio was detectedin MFP-BFP (p=0.0018), and MFP-TFP (p=0.02). We also found that density of woody species decreased significantly (-log) with the increase of diameter-height ratio. Woody species diversity can be relatively high in MFP (3.8±0.65) and low in TFP (3.03±0.37), with a significant difference (p=0.00016). These findings can be referred for orienting managements of forest landscape, and for biodiversity conservation in urban and suburban forests.
