Abstract:

Based on years of landscape application and observation of hardy waterlily, this article used the analytic hierarchy process to select 13 evaluation indicators from the aspects of ornamental value, adaptability, and ornamental period, and established a comprehensive evaluation hierarchical structure model. Combined with the fuzzy comprehensive evaluation method, a comprehensive evaluation of the landscape application value of 46 hardy waterlily varieties introduced in Hangzhou area was carried out. The results showed that growth vigor, flowering density, and flower color were the primary indicators influencing the landscape application value of hardy waterlily. According to the comprehensive evaluation scores, the 46 varieties are divided into four grades: Grade Ⅰ includes 9 varieties recommended for extensive promotion in local landscapes; Grade Ⅱ comprises 13 varieties with high application potential; Grade Ⅲ consists of 17 varieties suitable for moderate use; while Grade Ⅳ contains 7 varieties not advised for local landscape applications. This study aims to provide reference for selecting waterlily varieties suitable for landscape application and promoting new and superior varieties in Hangzhou area and across the southern Yangtze River region.
