Abstract
Shanghai,as a national mega city,has shortage in land resources and is bound by local environment,so that the greenway planning is facing difficulties.In this paper,we analyze the factors that affect the geenway planning in Shanghai,and put forward optimization based on the path planning model.According to the grenway planning optimization method,three kinds of greenway functions have been determined,namely the ecological greenway,the landscape greenway and the traffic grenway.By identifying important control nodes for geenway of each type,and analyzing construction characteristics of the three kinds of greenway,three minimum resistance models have been established respectively,and ultimately carried out the path recognition model which can help to path planning of greenway.关键词
