摘      要：Arboricultural research focusing on transport land use was lacking in Hong *** highway slopes were registered in the Systematic Identification of Maintenance Responsibility of Slopes in the Territory(SIMAR),abbreviated as SIMAR *** aimed to analyze patterns in the structure and species composition of the tree stock along a highway in Hong Kong and examined how a slope registration system could help explain the characteristics of urban *** 53 slopes and 52 verges along San Tin Highway,Hong Kong were randomly *** trees on each slope and verge were collectively sampled as a tree *** variables,namely tree abundance,species richness,maximum tree height,Shannon-Wiener diversity,Simpson s dominance,and Pielou s evenness were measured for each *** addition,a limited visual tree risk assessment was *** 7,209 trees in 23 species were *** richness was low,ranging from one to eight species per *** and non-SIMAR slopes were *** slopes had significantly higher species richness,diversity,evenness but lower dominance,with mean difference of 1.41 species,0.17,0.17 *** slopes were associated with lower tree risk *** training regression models,boosting as an ensemble method arbitrarily raised the explanatory power and the predictive accuracy of some *** height,length,angle and area could be significant predictors of the biodiversity-related *** research can sample more habitat characteristics related to the structure and species composition of slopes and verges which were important components of urban forestry.
