EVALUATION OF ECOLOGICAL FUNCTIONS OFURBANPARK LANDSCAPES BASED ON ANALYTICHERARCHY PROCESS METHOD

摘要

Urbanpark landscapes are both the earliest historic landscape that appeared and widely distrib- uted landscapes in the world. Urbanpark landscapes (ULs) are gaining increased attention from land- scape researchers. ULs are significant in environ- ment and ecological protection, as well as in leisure consideration and landscape utilization. Till now, few studies have discussed the reasonable ecologi- cal functions of ULs. It chances to reflect the blank space of study in this field. Thus, this research con- sidered the typical UL of Shenyang (capital of Liaoning Province), China as the study site. The urban green space, lakeside, and wetland urbanpark landscapes were established based on analytic hier- archy process method (AHP). During our research aesthetic function is neglected for high uncertain- ties under AHP, and ecological functions such as climate improvement, environment protection, comprehensive ecological benefit, environmental adaptation, community's richness, and plant diver- sity were selected as evaluation factors. Results of landscape ecology and AHP revealed the following (1) the ULs score followed the order lakeside> wetland > urban green space; (2) climate improve- ment and environmental adaptation factors were determined as the most important factors affecting ecological benefit functions, respectively; and (3) the quality of urban green space should be en- hanced and wetland should be preserved, and treespecies in waterland should be diversified. This study first evaluated ULs through AHP. Evaluation results could forward intentionality reference views and conservation management especially under ecological functions insights into guide ULs ar- rangement.
