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.

Assessing and predicting changes in ecosystem service values based on land use/cover change in the Bohai Rim coastal zone

“…Several scholars have evaluated the ESV of the Bohai Rim coastal zone and the impacts of LUCC on the ESV (Suo et al, 2011;Miao and Liu, 2014;Zhang et al, 2015a,b). They pointed out that the decline of ESVs in the region was mainly due to the loss of coastal wetlands.…”

“…The ecosystems around the Bohai Sea are an important part of the overall ecosystem of northern China. The main types of ecosystem in this area include estuarine delta wetland, farmland, aquaculture pond, salt pan, coastal mountain forest, coastal beaches and towns, which provide many ecosystem products and services (Suo et al, 2011).…”

“…Global scholars have focused increasing attention on the impact of LUCC on ecosystem services and have conducted extensive research on the global scale, national scale, regional scale and watershed scale, achieving remarkable results (de Groot et al, 2012;Song and Deng, 2017). However, most research has focused on terrestrial ecosystem services, and there has been less research on coastal and offshore marine ecosystem services (Suo et al, 2011;Li et al, 2016).…”
