Abstract

It is of great significance to estimate the changes of ecosystem service values (ESV) with land use changes under rapid urbanization proces. This paper calculated and analyze theland use change, ESV change and ESV flowing matrix of Bohai coastal region in 1980,2000,2005and 2013.Here were the main results: (1)from 1980 to 2013,the rapid proces of urbanization lead to land uses structure in Bohai coastal region changed dynamicaly,mainly reflecting in the continuous decrease offarmland, woodland,grasland,wetland,unused land and the substantial increase of construction land,while the area of water body increased first,then went down. (2)The change of land use structure led the total ESV in Bohai coastal region to increase slightly before 2005 and then went down,and the total ESV in 2013 was 600.5 bilion Yuan,decreased by 7.7% compared to that in 1980 level (650.4bilion Yuan). Meanwhile,the transfering to construction land caused the biggest losof ESV,reaching to 58.5 bilion Yuan during 1980 to 2013,which acounted for 45.9% of the total ESV los during 1980 to 2013. (3)The regulating service was the dominant ecosystem service function in Bohai coastal region ecosystem,contributing more than 65% of total ESV since 1980. (4)The top thre cities that had biggest ESV were Dandong,Tianjin and Dalian.The ESV of al the cities was going down except Yingkou,Dongying,Rizhao and Weifang. (5) It should promote the coordinated development of urbanization proces and ecological protection in Bohai coastal region by avoiding “unorderly spreading out” development and establishing ecological compensation mechanism during urbanization construction.
