Suitability of reserved coastal mudflat for land development--a case study in Yancheng, Jiangsu Province
摘要
Abstract
Evaluating the suitability of reserved coastalmudflatfor land developmentprovides a scientific basis for its exploitation and utilization.The evaluation systems ofthe reserved coastalmudflatwere established formthree aspects:physical suitability, ecological suitability and economic suitability. The evaluation systemintegrated D elphi method, criticalconditions method,and comprehensive index method through stepwise correction to determine the suitability of development level. The study area was in Yancheng City, Jiangsu Province. U sing the spatial analysis function in Arc GIS, area and spatial distribution of reserved coastal mudflat for land development suitability under different conditions were determined and the economic viability ofreserved coastalmudflatfor land developmentwas explored. The results indicated that the areas of high and moderate suitability based on natural conditions were 67395.01 and 50896.04 hm2 respectively.Furtherconsidering the ecologicalsuitability,the areas ofhigh and moderate suitability were 30327.75 and 40137.91 hm2 respectively (51.06% ofthe reserved coastalmudflat).Lastly,when the economic feasibility factors were taken into account,allthe reserved coastalmudflatcould be developed.This study can be a reference for policy making regarding the developmentand planning ofreserved coastalmudflat.关键词
