| 摘 要： | 为了解河涌沿岸植被特征及其与人类活动的关系，选取广州市南沙区4条河涌作为研究对象，对河涌沿岸的农业景观、工业景观和村落景观3种类型河段的植物景观特征进行了分析。结果表明:①河涌沿岸植物共计有70科126属144种，其中农业景观河段有45科51属58种，工业景观河段有25科33属40种，村落景观河段有64科119属130种。②河涌沿岸各景观类型河段植物区系分布均以广义热带成分为主，占比均达80%以上，符合所在区域气候特点。③植物功能需求差异和人为利用方式差异，导致不同景观类型河段的优势植物组成产生差异。农业景观河段，食用型果树表现出显著优势；工业景观河段，防护植物和城市绿化植物占有优势；村落景观河段，食用型果树和观赏型植物表现出显著优势。④3种景观类型河段植物多样性特征存在差异，植物丰富度、多样性和均匀度从高到低均为村落景观河段、农业景观河段、工业景观河段。⑤道路建设活动与农业景观河段乔木丰富度呈负相关。建筑物构造活动对各景观类型河段的植物多样性特征具有积极影响，其中对农业景观河段的影响体现在乔木的多样性上，对工业景观河段的影响体现在灌木的丰富度、多样性和均匀度上，对村落景观河段的影响体现在乔木和灌木的丰富度、多样性上。

| Abstract: | To understand the riparian plant characteristics and its relationship with human activities, this research selected 4 rivers in Nansha, Guangzhou City and analyzed the vegetation characteristics of riparian plants in agricultural landscape, industrial landscape and rural landscape. Results were as follows:(1) There were 144 species from 126 genera and 70 families, including 58 species from 51 genera and 45 families in agricultural landscape, 40 species from 33 genera and 25 families in industrial landscape, 130 species from 119 genera and 64 families in rural landscape. (2) Riparian floras were mainly tropical species, accounting for more than 80 per cent, which was consistent with the regional climate conditions. (3) Differences in functional requirements and utilization patterns of plants led to differences in the dominant plant composition of different land types:edible fruit trees showed significant advantages in agricultural landscape; protective vegetation and urban greening vegetation showed significant advantages in industrial landscape; edible fruit trees and ornamental vegetation showed significant advantages in rural land. (4) There were differences in plant diversity characteristics in three land use types, and their plant richness, diversity and evenness were ranked as follows:rural landscape > agricultural landscape > industrial landscape. (5) Road construction activity was negatively correlated with tree richness in agricultural landscape. Building construction activities had positive impacts on the plant diversity of all land use types. The impacts on agricultural landscape were reflected in tree diversity and tree evenness; the impact on industrial landscape was reflected in shrub richness, diversity and evenness; the impacts on rural landscape were reflected in tree richness, diversity and shrub richness and diversity. |
