Abstract:

As a concept based on greenway development, heritage corridor, which combined recreation and tourism development with ecological restoration and cultural conservation, has come into being in the United States since the 1980s. With rapid development in the study of greenway network, plans of heritage greenway network were proposed for heritage conservation as part of ecological infrastructure in regional scale in recent years worldwide. As many cases have shown, suitability analysis is the key in greenway planning study. Some approaches of greenway suitability analysis given in the former cases were too complicated and too much data dependent to be applicable in the Chinese condition. With GIS (geographic information system) technology and MCR (minimum cumulative resistance) model being used, a new approach of heritage corridor suitability analysis is designed to analyse and identify the suitability of potential areas for heritage corridors. This approach is featured in the following aspects: 1) A heritage corridor is defined as a linear landscape element that combines the function of recreational activities, heritage protection and ecological processes. 2) In addition to the physical faccors of heritages, the process of recreational use is the major concern in the definition of the suitability of a heritage corridor. 3) Recreational activities associated with heritages are considered as a horizontal process going across the landscape. This process is taken as an active process which overcomes the cumulative landscape resistance affected by land uses and covers. The less accumulative resistance a user is going to experience across the landscape, the more suitable the landscape is designated as heritage corridors. 4) The suitability of a landscape for a heritage corridor is therefore represented through the relative accumulative resistance in the process that a user experiences across the landscape towards or between heritage sites. 5) The calculation of accumulative landscape resistance is based on the cost-distance from the sources (heritage sites) to any points in the landscape.Different land uses and covers contribute differently to the resistance, and their weights are based on the evaluation by experts and inquiry of the local people. A case study in a rapidly urbanizing region, Taizhou City of Zhejiang Province, is presented.
