In this paper,analytic hierarchy process( AHP) was used to select 13 specific indicators to construct the evaluation system of woody landscape plant maintenance effectiveness from 3 aspects of ornamental,growth status and soil condition combined with qualitative and quantitative analysis,with the aim to explore an effective and scientific method to evaluate the effectiveness of landscape plant maintenance.展开更多

The investigation shows that there are 535 woody landscape plant species in the city in total(including variants, subspecies and cultivars), belonging to 199 genera of 77 families. Among the 535 species, there are 49 gymnosperm species of 16 genera, 5 families, 486 angiosperm species of 183 genera, 72 families(including 467 dicotyledon species of 174 genera, 69 families, 19 monocotyledon species of 9 genera, 3 families). The fi gures refl ect rich woody landscape plants in Jinan City. There are 286 tree species, accounting for 53.4% of the total species; 216 shrub species, accounting for 40.4% of the total; 33 vine species, accounting for 6.2% of the total, thus tree and shrub species are diversifi ed, while vine species are limited. Among all tree species, there are 103 evergreen species, accounting for 19.25% of the total; 432 deciduous species, accounting for 80.75% of the total; so deciduous tree species occupy a prominent position. Woody plants in Jinan City are applied in diversifi ed forms, but seldom in innovative forms. Problems in the current application of woody landscape plants in the local area are summarized as(a) there are diversifi ed tree species, but only a few of them are applied in high effi ciency;(b) evergreen tree species are less used;(c) indigenous tree species are insuffi ciently used. Therefore, suggestions are given as(i) combine landscape plants scientifi cally;(ii) promote indigenous tree species;(iii) introduce and domestic new species actively. The investigation results provide scientifi c theoretical support for the sustainable utilization of woody plant resources in Jinan City.展开更多
