基于AHP法的桂林市8个公园绿地植物景观评价

采用层次分析法（AHP法）构建了以生态功能、服务功能、美学功能3方面作为评价准则的桂林市公园植物景观综合评价体系,利用构建的体系对桂林市8个城市公园的100处景观样方从定性和定量的角度进行综合评价。结果表明:1）准则层权重值由高到底的排序为生态功能（0.539 6）、服务功能（0.297 0）、美学功能（0.163 4）。2）指标层中植物物种多样性（0.228 4）、植物群落多样性（0.126 3）、游憩空间的安全性（0.092 7）以及植物与生境的和谐性（0.075 1）位列权重值的前4位。3）两江四湖公园、七星公园、訾洲公园、西山公园、象鼻山公园、伏波山公园、南溪山公园、虞山公园8个公园建设水平主要处于Ⅰ级（景观质量非常好）、Ⅱ级（景观质量很好）。这表明桂林市公园植物景观总体较好。AHP法将定量评价与定性评价相结合，对营造舒适生态的公园植物景观具有一定的指导意义，并提供适合公园植物景观评价的方法。

Evaluation on Plantscape of Eight Parks in Guilin by AHP Method

Analytic hierarchy process (AHP) method was adopted to construct a comprehensive system for the evaluation of plantscape in the parks of Guilin City from the views of ecological function,service function and aesthetic function.The resultant system was used to evaluate 100 scenic spots within 8 urban parks in Quilin quantitavely and qualitatively.The results showed taht 1) the order of weight values of criterion layer from high to low was ecological function (0.539 6),service function (0.2970),and aesthetic function (0.163 4).2) As for the index level weights,the top four were plant species diversity (0.228 4),plant community diversity (0.075 1),the safety of recreation space (0.092 7),and the harmoniousness of plant and habitat (0.074 5).3) Eight parks were at levels between Ⅰ and Ⅱ,which showed that the plantscapes in the parks of Guilin were good.The AHP method combines quantitative evaluation with qualitative evaluation,which provides some guiding significance for the park plantscape design and evaluation.
