Abstract
The rapid urbanization process increases pressure of ecological environment protection, urban greenways help to improve this situation. And concept of healthy life is deeply recognized, making people have more demands for green space. At the same time, local landscape with regional culture characteristics has become a research hot spot. Urban greenway can provide ecological, cultural and recreational functions that are beneficial to urban environment, playing an important role in people daily life. Evaluation has become the core content of greenway system. Research on greenway planning has mainly focused on ecological and leisure services, paid less attention to needs of regional culture. Therefore, research on urban greenway system based on regional culture and spatial potential has certain value. The case of this study is Miluo City, located in the northeast of Hunan Province, China. Qu Yuan is a great patriotic poet in Chinese history and the world's four major cultural celebrities. His poetry and spirit have a profound influence on later generations. Miluo is the place where Qu Yuan drowning in to realized patriotic ideals. The construction of Quzi Park and Quzi Academy in Miluo City set up a unique historical and cultural landmark for people to worship Qu Yuan and inherit his spirit. Qu Yuan culture has an important influence on the development of local landscape. While current urban greenway construction has several problems, such as lack of cultural connotation, low level of ecological connection, and difficulty in satisfying residents' demand for entertainment. Therefore, the construction of urban greenway system cannot ignore local cultural background and historic heritage. Research used multi-source data including remote sensing image map, dem data, land use data, green space distribution map, etc. Interpreted spatial distribution information of green space and convertible potential, including park, protective green space, rivers and railways, etc. First of all, the framework of regional culture-ecology-recreation greenway system was constructed. Within this framework, there were primary indicators including cultural, ecological and recreational potential, as well as secondary indicators including elevation, slope and green space coverage level，etc. Then potential of spatial construction conditions was evaluated by GIS, and potential of culture, ecology and recreation was determined. Spatial construction potential was evaluated quantitatively through the indicators of greenway connectivity, satisfaction, service scope, distance from residential areas, etc. Moreover, analysis results were overlaid by GIS，and spatial comprehensive evaluation of greenway construction potential was analyzed. The results show that :(1) Cultural potential of river-based greenway is high, while cultural nodes such as Quzi Park and Miluo River Wetland Park have not become core nodes in greenway system. (2) Ecological potential of overall greenway is high, and ecological nature of riverside area is higher than that of urban construction area. (3) The recreational potential of urban greenways is low, and small parks were lack of connection. Finally, based on regional culture and spatial potential, three strategies were pospoed: (1) cultural parks could be taken as the core to enhance cultural characteristics of surrounding green space in greenway system. (2) For road-based greenways, ecological network can be formed by combining with pocket parks. (3) For waterway-based greenways, recreational function of greenways can be improved by adding available space on banksides and waterfront sidewalks. This research could connect the regional culture with greenway system, build urban green corridor from cultural perspective, and choose the reasonable land for green space construction based on spatial potential, helping to enhance attractiveness of urban linear space.
