Comprehensive Evaluation Construction Of The Landscape Value Of Ornamental Prunus Mume And Application Advices In Nanjing Area

Prunus mume is one of important ornamental plantings belonging to Rosaceae family Prunus genus.Ornamental prunus mume is different from mume for fruiting,which is only or mainly used for viewing and appreciating.Prunus mume enjoys a long history of cultivation.Currently research of ornamental prunus mume most focus on resources investigaion,new variety breeding,ornamental characters study,looking into cultivation history,traditional and cultural meanings' analysis and multiple application forms in landscape.On the other hand,comprehensive evaluation for ornamental prunus mume's landscape value has not yet been carried out.This thesis chose 27 types of major ormamental prunus mume in Nanjing area as research materials,evaluate every variety's comprehensive lansdscape valuation including ecological value,ormamental value,social and cultural value and economic value 4 main factors.Based on diverse purpose and ways in appliscation of urban landscape,this comprehensive evalution provides reasonable reference for ormamental prunus mume's selecting and screening.The main conclusions were listed as follow:(1)Build ornamental prunus mume comprehensive evaluation system via the method of Analythis Hierarchy Process(AHP).The order of each index's weight in criterion level is ecological value>ornamental value>social and cultural values>economic value.The factor levels' order is carbon fixation>oxygen release>cultural connotation>corolla>cooling>flower yield>flowering period>hurmidification>WUE>fragrance>reproductive ability>educational value>shape>seasonal variation>application types>adaptability>seientific value>medicinal value.The ecological value is the highest index among all the others which is 0.4921 and nearly half of it's total points.It means the ecological value will be the main and the most important property in comprehensive evalutaion of ornamental prunus mume.The ornamental value follows next which is 0.3094,it also has a big influence on ornamental prunus mume's evaluation.The social and cultural value's weight is a little higher than the economic value.Among all the indexes,carbon fixation?oxygen release?cooling?cultrual connotation?corolla and flower yield ranks in the front whta their weight are all above 0.07,especially carbon fixation and oxygen release which weigh more than 0.15.Besides,scientific value and medicinal value are the factors that affects least on the comprehensive evaluation.(2)According to ressults of comprehensive evaluation of 27 ornamental prunus mume,rank is listed as follow:P.mume cv.Meiren Mei>P.mume cv.Subai Taige>P.mume cv.Fufen Chuizhi>P.mume cv.Mihua Guhong>P.mume cv.Yanglao Chuizhi>P.mume cv.Sanlun Yudie>P.mume cv.Feisi Chuizhi>P.mume cv.Jinzhi Dongyun>P.mume cv.Kouban Dahong>P.mume cv.Wan Tiaozhi>P.mume cv.Danban Zaobai>P.mume cv.Fenhong Zhusha>P.mume cv.Danban Huangxiang>P.mume cv.Shi Chu Jin>P.mume cv.Nanjing Hongxu>P.mume cv.Danya Gongfen>P.mume cv.Danban Tiaozhi>P.mume cv.Shuangbi Chuizhi>P.mume cv.Laorenmei Dahong>P.mume cv.Danzhuang Gongfen>P.mume cv.Huqiu Wanfen>P.mume cv.Yinhong Zhusha>P.mume cv.Nanjing Hong>P.mume cv.Zaohua Lu'e>P.mume cv.Zhouban Taige>P.mume cv.Han ong>P.mume cv.Wuy Yu.All the ornamental prunus mume in the study can be divided into 5 levels basing on the final comprehensive evaluation ressults,which is high(?),relatively high(?),general(?),relatively low(?)and low(?),3 species' evaluation scores are high,ranking in the ? level,accounted for 11%of the total number;9 species rank in the ? level and occuppied 33%;both ? and ? level have 7 species each,making up 26%of all species;only 4%percent,1 species's evaluation score is low and ranks in Vlevel.P.mume cv.Meiren Mei?P.mume cv.Subai Taige?P.mume cv.Fufen Chuizhi?P.mume cv.Mihua Guhong?P.mume cv.Yanglao Chuizhi?P.mume cv.Sanlun Yudie?P.mume cv.Feisi Chuizhi?P.mume cv.Jinzhi Dongyun?P.mume cv.Kouban Dahong?P.mume cv.Wan Tiaozhi?P.mume cv.Danban Zaobai and P.mume cv.Fenhong Zhusha are species of high comprehensive evaluation in landscape,which are suitable for the wider utilization of urban landscape construction in the background of modem ecological environment.
