Response of Ecosystem Service Value to Land Use Change in Coastal Zone of Bohai Sea in Last 30 Years

Abstract

Aimed to evaluate response of ecosystem service value to land use change in coastal zone of Bohai sea in last 30years, Series satellite remote sensing images obtained in 1988, 1998 and 2007 were employed to surveyed land use change integrated field surveying,firstly.Then an unit table of ecosystem services function value of main land use type was created. The response of ecosystem service value to land use change in 13 coastal zone regions of the Bohai sea in last 30 years was assessed. The result showed: the ecosystem service value lost 60.74×108RMB in coastal zone of Bohai sea caused by land use change in last 30years. Amony the 13 coastal zone region, the ecosystem service value increased only in Yantai coastal zone region and Dalian coastal zone region, there are 0.36×108RMB and 0.20×108RMB,respectively. While the ecosystem service value reduced in 11 coastal zone regions, such as Yingkou coastal zone region, Panjin coastal zone region, Binzhou coastal zone region, et al.the total lost value is 60.30×108RMB.
