基于景观资源的乡村绿道风貌识别与分区OA

[Objective]To address the insufficient resource integration and imprecise spatial characterization in rural greenway planning,this study establishes a multidimensional landscape resource identification system integrating ecology,culture,and production,and proposes a scientific zoning method for optimizing greenway design.[Method]Using the countywide road network of Jinzhai County,Anhui Province as the primary study object,three buffer distances(300 m,800 m,and 1 200 m)were established along roads to analyze the gradient effects of roads on adjacent landscape resources.A spatially constrained multivariate clustering model(SCMC)was introduced and integrated with multi-source data and GIS to identify landscape-resource characteristics across three dimensions-natural ecology,cultural activities,and agricultural production-and dominant landscape-character zones were delineated based on the clustering results.[Result](1)Ecological resources clustered in the southern region,showing a"high-south,low-north"pattern,while cultural resources concentrated in the north with the lowest proportion of transportation facilities,and agricultural resources exhibited significant spatial heterogeneity.(2)Five dominant greenway zones were identified with strong regional independence,particularly in the distribution of cultural resources,and the greenways can be functionally classified into four types-ecological,cultural,production-oriented,and composite-prioritizing,respectively,ecological conservation and tourism/recreation;cultural-heritage transmission;agricultural economic value;and an organic integration of cultural and productive functions.(3)Four functional zones(ecological,cultural,agricultural,and composite)were delineated in Jinzhai County.[Conclusion]In view of the complex nature of rural environments,the identification of rural greenway landscape features should transcend the traditional single-dimensional evaluation paradigm and establish a multidimensional identification framework;through differentiated strategies-such as ecological-corridor construction,culture-industry linkages,and the integration of agricultural production-multifunctional synergy and spatial optimization of rural greenways can be achieved,thereby providing scientific support for rural revitalization.
