Aesthetic evaluation of plant landscape based on principal factor analysis and SBE in Wetland Park – A case study of Jinlong Lake Wetland Park (China)

Abstract

The aesthetic value of 35 plant landscape samples of Jinlong lake wetland park in Xuzhou city of China were evaluated with principal factor analysis and SBE method. The results showed that: The SBE value of 35 plant landscape samples fluctuated greatly and the evaluation value of the principal factor did not change much. The order of SBE mean values of different types was: plant landscape on both sides of the roads > plant landscape beside buildings and surroundings > typical plant community > waterfront plant landscape. The order of value of the principal factor analysis of different types was: plant landscape on both sides of the roads > typical plant community > plant landscape beside buildings and surroundings > waterfront plant landscape. The principal factor evaluation method contained more than 90% information of seven evaluation factors, while the SBE method mainly evaluated from “plant aesthetic factors”. The satisfaction of waterfront plant landscape was low, the transformation of plant landscape should focus on increasing the species of waterfront plants, especially native plants, building natural revetments, creating rich canopy lines.
