摘要
以西安市38个公园绿地植物景观单元(100m^2)为对象,采用层次分析法(AHP法)对景观质量进行评价,以聚类分析法对西安市植物物种丰富度、多度和景观特征进行分析。结果表明,景观单元的植物景观质量主要受植物与整体环境的协调性(x8)和植物景观时序多样性(x4)影响;38个景观单元中优秀的景观单元(Y_(AHP)≥7.00)有17个,占总体的44.7%,良好的景观单元(6.00<Y_(AHP)<7.00)有18个,占总体的47.4%,欠佳的景观单元(Y_(AHP)≤6.00)有3个,占总体的7.9%;根据景观质量值(Y_(AHP))进行聚类分析,将38个景观单元分为4类。
Thirty-eight plantscape units(100 m 2 each)in the park green spaces in Xi an were selected as research objects for landscape quality assessment by using analytic hierarchy process(AHP),and the plant species richness,abundance,the plantscape characteristics of park green spaces were analyzed by using cluster analysis.The results showed that the coordination of plant and overall environment(x 8)and plantscape time diversity(x 4)had significant effects on plantscape quality of landscape units.Among the 38 landscape units,17(accounting for 44.7%of the total)were excellent(Y AHP≥7.00),18(47.4%)were good(6.00<Y AHP<7.00)and 3(7.9%)were poor(Y AHP≤6.00).According to clustering analysis based on landscape quality values(Y AHP),the 38 landscape units were divided into 4 categories.
