Abstract:

【Objective】 By constructing the traditional rural landscape security pattern in towns, the fragile cultural and ecological landscape system in traditional rural areas can be maintained. 【Method】 Based on the theory and method of “Source-Sink”, we took Xishan in Taihu Lake Scenic Spot as an example. We identified the category, location, scope and intensity of the “source” of ecological and cultural landscape system using the four indicators: “land use type”, “slope”, “vegetation coverage” and “distance from road” as evaluation elements of resistance “sink”. Based on the ArcGIS 9.3 platform and minimum cumulative resistance model (MCR), the processes of “source” and “sink” of the traditional ecological and cultural landscape in Xishan were calculated to obtain the security pattern of both ecological and cultural landscape. 【Result】 High-level areas of ecological and cultural security in Xishan accounted for 67.11% and 38.29%, respectively, of total areas; while medium-level areas of ecological and cultural security in Xishan accounted for 19.88% and 49.16%, respectively, of total areas; low-level areas of ecological and cultural security accounted for only 13.01% and 12.55%, respectively, of total areas. 【Conclusion】 The theory and method of “Source-Sink” have strong applicability for constructing traditional rural landscape security pattern in Xishan. They can play an active role in the simulation of the ecological and cultural landscape processes, the classification of ecological and cultural landscape security levels, and for zonal conservation and management of traditional rural landscape areas.
