Land use and land cover changes and their impacts on ecosystem service values in old industrial cities:A case of Shenyang city
Maintaining and improving ecosystem services is an important base for ensuring sustainable development of old industrial cities.Using remote sensing image interpretation and improved equivalent factor method,the spatiotemporal change of land use/cover in Shenyang city and its impact on ecosystem service values were quantitatively analyzed.The results showed that:(1)Arable land was the main land use type in Shenyang,construction land and water area were increasing,while grassland,woodland and other important ecological land were decreasing;the time that the land use/cover change was the most significant was from 2005 to 2010.(2)The ecosystem service values were mainly from regulated services,arable land and water area contributed over 80.00%of the service values,while grassland and woodland contributed only 20.00%,which were also declining annually;the spatial pattern of ecosystem service values in Shenyang presented a circle layer structure,the ecosystem service values in central location was lower and in peripheral areas was higher.The ecosystem service values in Shenyang increased by 66 million Yuan per year on average,and the value per capita decreased by RMB 47.95 Yuan per year on average.It is suggested to systematically manage urban and rural land resources,strengthen the protection and quality improvement of forest land and grassland,control the expansion of new urban areas and industrial parks,and improve the output rate of unit land resources.
