| In the process of rural urbanization,it is difficult to solve the Macro-problems such as the degradation of rural ecosystem,the shortage of public service facilities and the decline of rural culture in a single village-based rural development model.In this context,the construction of rural areas with Jiangsu characteristics proposed to cover three relatively clustered villages in the "Tuan" area,focusing on the correlation and interaction of pilot villages,in order to facilitate the formation of a region with continuous space and obvious overall demonstration effect.The connectivity and versatility of Greenway make it an important space carrier to promote the flow of various resource elements,which is conducive to the implementation of the relevance and interaction in the development of multi-village linkage.This paper takes the planning of rural Greenway in the area of "Tuan" as the research object,starting with the development process and planning method of the greenway,summarizes the relevant planning theory of the existing greenway;based on the relevant theories of the existing rural greenway,discusses the characteristics,attributes and planning methods of the rural Greenway in the area of "Tuan";takes the "Tuan" area of Jiangyan District in Taizhou City as the research area,and develops it.Based on the Landscape Character Assessment(LCA),the planning strategy of rural Greenway in "Tuan" region is put forward,and the construction process of rural Greenway in "Tuan" region is put forward,and the application research of the evaluation model and construction method of Greenway resources is carried out.Finally,the greenway network structure in the target region is determined.The main results of this paper are as follows:1.In the way of literature review,the existing greenway planning methods and technology applications are sorted out.This paper summarizes the planning paradigm of greenway network construction,that is,the mode of "current situation investigation-factor evaluation-Spatial Layout Planning-network structure optimization".The theme of this paper is rural Greenway Planning and 3S technology application,and its theoretical research and application status are summarized.2.Drawing on the method of British Landscape Character Assessment,the rural landscape of "Tuan" area in Jiangyan District of Taizhou City was described and judged by means of data collection and field investigation,and the assessment method was adjusted adaptively according to the characteristics of the study area.Then,it is coupled with the core functions of the greenway to get the active protection strategy based on the ecological function and the opportunity sharing strategy based on the tourism service function,which provides a reference for the study of the characteristics evaluation of rural landscape and the greenway planning strategy in China.3.Through screening the authoritative evaluation system related to greenway,the preliminary framework for the analysis of rural greenway resources is determined.Then,based on the site landscape characteristics and the "Tuan" regional Greenway Planning strategy,six indicators frameworks with easy access to data and high representativeness are constructed for the suitability analysis process of different types of Greenway nodes,corridors and cost aspects,which provide a reference for the evaluation of the impact factors of rural greenway.4.Through the method of suitability evaluation and cost distance analysis,the construction of rural greenways in the "group" area is carried out,and the green road paths generated by different methods and different types of green road paths are compared and analyzed,and the differences among different types of greenways are identified.Finally,from the path space distance,intersection,corridor distribution density and other aspects,the integration of greenway,the final greenway network layout.It provides a theoretical reference for the construction of rural Greenway Planning level. |
