Analysis Of The Local Ornamental Plant Environment Suitability And Space Layout In South China

Climate warming and acid rain was the global environment problems, a the response ofplant to environmental changes was also governments, organizations and scientific workers arehighly valued. And the landscape planning features local landscape plant application also hascaused the people’s attention.Based on eco-fitness theory,establish temperature suitabilitymodel precipitation suitability model Sour rain suitability model and environment suitablemodel this paper analyzes the south China area44local landscape plant environmentsuitability and tendency.According to temperature, precipitation factor, soil factor PH factorand environmental suitability and tendency of the distribution of plant environment,in the endthis paper make suitable spatial distribution, greening tree species selection for landscapeplanners to provide the reference.The article analyzes the environmental suitability and its trends in South China and theresult shows that temperature was the main limiting factor in environmental suitability ofsouthern China, due to geographical differences, restrictive environmental factors also showsignificant regional and zonal distribution. Pearl River estuary and western Yunnan and FujianEast were obvious. the response to environmental change for particular species have a certainsimilarity, and suitability in the appropriate type and compared with the appropriate type ofspecies up to this study, so it can be consideredresults may represent a common response by theSouthern Region native landscape plants to environmental change.For the environmentalsuitability of the species propensity for change in rate, the most species change speed slowwhich can stand for plants response speed in the south China.For the environmental suitabilityof the species propensity,its tendency rate most species, and change slow in the south China.Cerasus campanulata and Schima wallichii distribution more special,and Licuala spinosachanging fastest. Based on species of precipitation suitability distribution more uniformdistribution no specific tree species,and circassian bean Albizia chinensis CamphoraOfficinarum change quickly. Species suitable forSour rainappropriate distribution more evenlydistributed and no special species,and Thespesia populnea and Garcinia multiflora Champhas change quickly.Environmental suitability distribution was relatively, and tea changingfastest.This paper comprehensive environmental factors of suitability and tendency toinfluence the growth of a plant, and that dynamic temperature suitability index distribution. Onthe whole,the south China area most area for appropriate areas, not suitable for smallareas.Finally, according to the south China area local landscape plant environment suitabilityand changing trend divides the three regions, and for each district chose the right now was a tree species and future appropriate tree species, for landscape planners choose plants providethe basis.
