Comprehensive Evaluation Construction Of The Landscape Value Of Oranamental Peachesis And Application Advices

Ornamental peaches are important ornamental trees belong to Rosaceae family Cerasus genus.There are many varieties of resources and have broad development and application prospect.The current research mainly focuses on resources investigation,varieties classification,introduction and domestication,culture and breeding,however,studies on comprehensive evaluation of the ornamental peaches’ landscape value is involved little everywhere.The comprehensive evaluation was based on the 26 ornamental peaches resources in Nanjing area which include ecological value,ornamental value,social and cultural values and economic value and the study was carried out in 2014 and 2015.Then,according to the final results,merit and demerit of the 26 resources and reasonable disposition programs have been cleared in order to provide reference for the construction of urban ecological civilization.Conclusions of each research were listed as follow:1.Analytic Hierarchy Process(AHP)was used to establish the comprehensive evaluation system for ornamental peaches.The weight orders of the criterion level are ecological value>ornamental value>social and cultural values>economic value.The index level refers to specific indicators related to comprehensive evaluation.The sort orders on factor weights for the criterion level and index level are carbon fixation and oxygen release>flower>cooling and humidification>accumulating dust>cultural>connotation>fruit>fruit economic benefits>WUE>scientific value>leaf>appearance>reproductive ability>application types>educational value>adaptability>medicinal value correspondingly.The ecological value with largest weight in the criterion level is a most important and basic property in comprehensive evaluation for ornamental peaches(0.4995),basically is half the total weight and followed by ornamental value which greatly affect the comprehensive evaluation of ornamental peaches.The economic value plays a smallest role in the comprehensive evaluation.On the index level,carbon fixation and oxygen release,flower,cooling and humidification with a larger weight in the index level is a major criterion affecting the comprehensive evaluation for ornamental peaches,which have the weight bigger than 0.1.However,adaptability and medicinal value are the factors with relative small influence on the comprehensive evaluation.2.The comprehensive evaluation assessment for ornamental peaches.Prunus.persica var.duplex ’Mantianhong’>P.persica var.duplex ’ Juhuatao’>P.persica var.compressa 4Jinxiayoupan ’>P.persica ’Huayulu’>P.persica var.densa ’Shouxiangtao’>P.persica’ Huangjinmeili ’>P.persica var.duplex ’ Wubao ’>P.persica var.compressa’Hongyepantao’>P.persica var.compressa ’Baimangpantao’>P.persica var.Duplex’Hongfenjiaren’>P.persica var.duplex ’Hongyetao’>P.persica ’Zhubo 6’>P.persica var.nectarina ’Zijinhong 2’>P.persica var.nectarina ’Ruiguang 19’>P.persica’ Zhuxingtao ’>P.persica ’ Beileishisheng ’>P.Persica ’ Yejihong ’>P.persica’ Huogehongye’>P.persica var.compressa ’Hungroupantao’>P.persica ’ Cuizhitao’>P.persica ’Jintong 6’>P.davidiana ’Zouxingtao’>P.persica var.duplex ’Jiangtao’3.According to the final results,the ornamental peaches could be arranged as high(Ⅰ),relatively high(Ⅱ),general(Ⅲ),low(Ⅳ)and relatively low(Ⅴ)for 5 grades.There are two high ornamental eaches,high ratio 8%;twenty relatively high ornamental peaches,relatively high ratio 80%;four general ornamental peaches,general ratio 15%;no low and relatively low grades.Prunus.persica var.duplex ’Mantianhong’,P.persica var.duplex’Juhuatao’,P.persica var.compressa ’ Jinxiayoupan’,P.persica ’Huayulu’,P.persica var.densa ’Shouxiangtao’,P.persica ’huangjinmeili’,P.persica var.duplex ’Wubao’,P.persica var.compressa ’Hongyepantao’ with high comprehensive value,which can be widely popularized in urban green space.
