摘　　要：为深入探究中国城市的杂草物种组成、空间分布及其主要影响因素,本研究选取我国98个市(县)的城市草坪杂草作为研究对象,基于2002–2024年间相关文献分析,运用Jaccard相似性指数对β多样性进行度量。结果表明:(1)城市草坪杂草优势种有208种,隶属40科137属,其中菊科植物占比最高(22.12%)。植物区系地理成分复杂,世界广布科占据显著优势(共23科),但在属水平上,温带分布属的数量(57个)超过热带分布属(42个),科、属两级热带/温带成分比分别为2.33和0.74。(2)入侵杂草有37种,隶属11科,以菊科、禾本科和豆科为主(共占59.46%),其中恶意入侵种10种,严重入侵种11种,局部入侵种4种,一般入侵种12种。(3)城市间杂草组成相似性普遍较低,其差异性与β多样性理论相符,主要受地理距离和气候条件的共同影响。研究结果可为后续城市草坪杂草的科学管理、生物多样性保护和城市可持续发展提供理论基础。Aims:This paper conducts a comprehensive review of literature from the past two decades,focusing on two primary objectives.First,it explores the composition of dominant weed species in urban lawns across China,including the types and characteristics of invasive weeds.Second,it investigates the key factors influencing the distribution and spread of weeds in urban lawns in China.This study aim to provide a theoretical foundation for the scientific management and control of weeds in urban lawns and help protect biodiversity and promote sustainable urban development.Additionally,these findings can support efforts at monitoring weed population dynamics to maintain ecological balance and enhance the health and sustainability of urban green spaces.Methods:This study conducted a comprehensive review of the literature on urban lawn weeds in 98 cities across China between 2002 and 2024.A statistical analysis of the weed species identified in the literature was carried out after gathering information on dominant weed species,including their Chinese and Latin names,family and genus details,life forms,and flora.These data were used to determine the species,origin,degree,and route of invasion for invasive weeds.Furthermore,β-diversity was assessed using the Jaccard similarity index.The data for this study were sourced from the CNKI database,WANFANG DATA,and VIP database.Statistical analyses were performed using R and SPSS software.The correlation between invasive weed distribution and climatic factors was examined through a nonlinear relationship,and the primary climatic factors influencing the distribution of weed species in urban lawns were identified using redundancy analysis(RDA).Together,these methods enabled a deep exploration of the species composition,spatial distribution,and main influencing factors of urban weeds in China.Results:(1)A total of 208 dominant weeds,spanning 40 families and 137 genera,were identified in urban lawns.The Compositae was the most prevalent in the literature,constituting 22.12%of the total.T
