摘　　要：为了解人为干扰对河涌沿岸植物景观特征的影响,选取广州市南沙区4条河涌作为研究对象,采用ANOVA单因素方差分析轻度、中度以及重度人为干扰强度下河涌沿岸植物景观特征的差异及不同植物景观特征因子之间的相互关联作用。结果表明:1)不同人为干扰强度下河岸植物景观在数量特征、生活型特征、功能特征以及绿量特征方面存在显著差异。与轻度干扰相比,中度干扰和重度干扰下的河岸植物种类平均多1种、乔木占比平均高26.8%和18.5%,草本占比平均低25.6%和20.8%、生态植物占比平均低17.0%和24.8%。中度干扰下食用植物占比较高,重度干扰下观赏植物占比较高。2)从河岸总体植物景观特征来看,生态植物占比随建筑物盖度增加而降低,食用植物占比和观赏植物占比随建筑物盖度增加而增加,植物绿量随风水植物占比增加而增加。3)不同人为干扰强度下河岸植物景观特征要素之间的相互关系存在差异。轻度干扰下,植物种类、乔木占比、风水植物占比随建筑物盖度增加而增加,植物绿量随建筑物盖度、风水植物占比增加而增加;中度干扰下,生态植物占比随建筑物盖度增加而降低,食用植物占比随建筑物盖度增加而增加,绿化覆盖率随植物数量、生态植物占比增加而增加;重度干扰下,绿化覆盖率随生态植物占比增加而增加,植物绿量随植物种类增加而增加。参考不同人为干扰对河涌沿岸植物景观特征的影响分析,为珠三角河涌沿岸植物景观风貌延续与建设提出了建议。To understand the effects of the human disturbance intensity on riparian plant landscape characteristics(RPLC),4 rivers in Nansha,Guangzhou City were selected as the research objects to analyze the differences of RPLC under the low,moderate and high human disturbance intensities and the correlationships among different plantscape characteristic factors by ANOVA single factor variance.The results were as follows.1)There were significant differences in quantity,life style,function,and green quantity characteristics of riparian plantscape under the different human disturbance intensities.Compared with low human disturbance,the average species under moderate and high human disturbances was one more,the average proportion of tree were 26.8%and 18.5%higher,the average proportion of herb were 25.6%and 20.8%lower,and the average proportion of ecological plant were 17.0%and 24.8%lower.The proportion of edible plant was relatively high under the moderate human disturbance,and the proportion of ornamental plant was relatively high under the high human disturbance.2)From the view of overall RPLC,the proportion of ecological plant decreased with the increase of building coverage,the proportion of edible and ornamental plants increased with the increase of building coverage,and the green quantity increased with the increase of the proportion of"Fengshui(geomantic omen)"plants.3)There were differences in the correlation between RPLC under different human disturbance intensities.Under the low human disturbance,with the increase of building coverage,plant species and the proportion of tree and ecological plant increased,and green quantity increased;under the moderate human disturbance,with the increase of building coverage,the proportion of ecological decreased,the proportion of edible plant increased,and green coverage increased with the plant amount and proportion of ecological plant;under the high human disturbance,green coverage increased with the proportion of ecological plant and green quantity increased with the increase o
