Response of Ecosystem Service to Landscape Change in Panjin Coastal Wetland

In this paper, landscape change of Panjin coastal wetland was surveyed by interpreted data of remote sensing images from 1990 to 2010. Some methods including market value, engineer value, value factor were employed to assess response of the ecosystem service to wetland landscape change. The result showed that reef, rice crop and estuary water were three main landscape type in Panjin coastal wetland. The ecosystem service value response to the wetland landscape change with 8.39 × 108 RMB decreased from 1990 to 2010. The wetland landscape change caused 6.64 × 108 RMB purification function value lost, 2.23 × 108 RMB habituation function lost and 2.06 × 108 RMB culture and recreation function lost, while only added 2.83 × 108 RMB food and materials production function value. It is unreasonable to reclamate coastal wetland for fishing and planting from total ecosystem service function.
