Mapping of wetland reserve boundary in coastal zone utilizing spatial constraints assessment
摘要
Abstract
The delineation of wetland reserve boundary is essential not only to the functional sustainability of wetland,but also to the coordination of land resource configuration and spatial distribution among wetland protection,farmland utilization and urban construction.This paper is conducted to analyze wetland reserve boundary in light of the theory of source and sink landscape interaction by using a case study of the southern bank of Hangzhou Bay.The spatial differentiation of wetland protect source and sink landscape including ecological bound and spatial constraints assessment were analyzed respectively.And wetland reserve boundary and its type were delineated by using the minimum cumulative resistance model.The case study demonstrated the applicability of research strategy by using minimum cumulative resistance model based on spatial constraints assessing and ecological bound zoning in delineating wetland reserve boundary.While accounting for 52.69％ is of the ecological bound,high constraint district or medium constraint district,only percent of 34.53％,12.79％ are low constraint district and none constraint district,showing an intensive constrained trend of spatial pattern.The area of wetland reserve boundary and buffer zone have the area of 49.1 1 km2,24.07km2 respectively,taking the percentage of 5.47％ in the southern bank of Hangzhou Bay,revealing that the space of wetland reserve is limited.In addition to ecological bound,wetland reserve boundary can be classified into three types including preserved forest area,farmland expansion and water SourceS.关键词
