Study On The Route Selection Of Rural Greenway Based On The Function Coordination

At present,China is in the stage of rapid development of urbanization and in the ascendant period of rural tourism.The greenway can form unique tourist routes which links rural natural resources and human resources,besides the greenway has many functions,it can improve the rural ecological environment and protect and inherit the rural culture.it is important to make the route selection reasonable of greenway for playing the functions of greenway,So the study of the method of greenway's route selection is of very important significance.As the start point of functions of rural greenway,the paper takes the synergetics as the theoretical basis and uses the model of coordinated degree to study the method of route selection of rural greenway,then applying it to the practical case.The main contents of this paper are as follows:(1)Through the collection and analysis of the literatures of greenway at home and aborad,the four functions of the recreational function,ecological function,landscape function and traffic function of the rural greenway were evaluated,and based on the theory of synergetics to analyze synergistic mechanism of four functions.(2)Based on the theory of synergetics,choosing 13 evaluation index of the route selection of rural greenway,such as the number of recreational resources connected,the diversity of recreational resources,the accessibility of recreation,and the ecological protection and so on.and clearing the evaluation criteria of indicators,then determining the threshold value of the index,calculating the weight of each index;finally establishing the functional collaborative evaluation system and method of route selection of rural greenway.(3)Finally,taking the Beautiful Countryside Demonstration Area in Yuancheng District of Heyuan as an example,combining the current conditions and resources of the demonstration area,this paper selected 15 potential greenway lines such as 199 Township Road,189 Township Road and 201 Township Road and other lines.Based on method of the rural greenway route selection,the potential greenway routes are analyzed and evaluated,and the coordination degree is calculated.The results show that the coordination degree of 15 potential greenway lines is different,and the road that coordination degree is equal to or higher than 0.5 will be selected,then the 199 township road,174 rural road,landscape road and other 11 lines initially identified as the demonstration area greenway line,because of theconnectivity of greenway,the initial rural greenway lines of demonstration area need to be adjusted and optimized,ultimately determining the greenway network planning layout of demonstration area.
