  • This paper concerned with utilize RS and GIS technic to analyzing the variation process of Landscape pattern in Jiangsu Yancheng Coastal Wetland 1983~2013. Wetland Component retention rate by quantitative analysis method and wetland type contribution rate of specific transfer process. The structure characteristic and change of landscape evolution direction.The result shows that: 1983~2013, the natural landscape area in Jiangsu Yancheng coastal wetland reduced by 1211.22 km2, its proportion declined 21.63%,presents Gradually decreasing trend. Compared 2013 with 1983, the area of artificial Landscape increased to 1492.09 km2 year after year, Salt field area appears falls, Breeding pondareas have the growth to 930.28 km2. Among the natural wetland landscape, retention rate of sea water relatively high(74.4%), the most of the export type is mud flat. Among the artificial Landscape, the retention of Farm woodland and Breeding pond is relatively high, they are 79.0% and 60.9% respectively, the most of export type are Building lots (76.1%)、Farm woodland(86.6%).The cumulative contribution rate of natural succession advantage transfer is 35.21%. Thus, the dominant factor of the dynamic variation of the Landscape pattern in Jiangsu Yancheng coastal wetland 1983~2013 human activity, mainly reflects in enclose tideland for cultivation of natural wetland.

Abstract: This paper concerned with utilize RS and GIS technic to analyzing the variation process of Landscape pattern in Jiangsu Yancheng Coastal Wetland 1983~2013. Wetland Component retention rate by quantitative analysis method and wetland type contribution rate of specific transfer process. The structure characteristic and change of landscape evolution direction.The result shows that: 1983~2013, the natural landscape area in Jiangsu Yancheng coastal wetland reduced by 1211.22 km2, its proportion declined 21.63%,presents Gradually decreasing trend. Compared 2013 with 1983, the area of artificial Landscape increased to 1492.09 km2 year after year, Salt field area appears falls, Breeding pondareas have the growth to 930.28 km2. Among the natural wetland landscape, retention rate of sea water relatively high(74.4%), the most of the export type is mud flat. Among the artificial Landscape, the retention of Farm woodland and Breeding pond is relatively high, they are 79.0% and 60.9% respectively, the most of export type are Building lots (76.1%)、Farm woodland(86.6%).The cumulative contribution rate of natural succession advantage transfer is 35.21%. Thus, the dominant factor of the dynamic variation of the Landscape pattern in Jiangsu Yancheng coastal wetland 1983~2013 human activity, mainly reflects in enclose tideland for cultivation of natural wetland.
