Abstract:

To promote the beautiful village construction and maximize the value of rural greening, landscape woody plants in Zhoushan island village were evaluated comprehensively and classified by analytic hierarchy process (AHP) based on quantitative character analysis. The results provided the scientific basis and reference for the allocation of landscape woody plants in Zhoushan island village. The quantitative character analysis showed that 253 plant species from 78 sampling plots of 10 villages were recorded belonging to 213 genera and 92 families comprised of trees (28.9%), shrubs (30.8%) and herbs (40.3%). According to the plant origin, the proportion of native species and exotic species among 253 plant species was 50.6% and 49.4%, respectively. Most trees and herbs are native, but 64.1% shrubs are exotic. Among the trees,the relative abundance, relative dominance, relative important value of Cinnamomum camphora is the largest. Among the shrubs, both the relative abundance and relative important value of Photinia×fraseri is the highest. The frequency of Rhododendron simsii and the relative dominance of Fatsia japonica is the largest, respectively. According to the results of comprehensive evaluation, 16 trees and 17 shrubs were rated as Grade I, 28 trees and 23 shrubs were rated as Grade Ⅱ, 20 trees and 21 shrubs were rated as Grade Ⅲ, 12 trees and17 shrubs were rated as Grade Ⅳ, respectively. The trees of Grade I and Grade Ⅱ can be used as candidate keynote species and backbone species in the village greening of Zhoushan island. The trees of Grade Ⅲ are supplementary to trees of Grade I and Grade Ⅱ to enrich the plant species. However, the trees of Grade Ⅳ are not recommended or carefully selected in the allocation of woody plants in Zhoushan island village.
