英文摘要Rapid urbanization is a global phenomenon that has altered many ecosystems, generating ecological risks such as causing a decline in many ecosystem services. In this study, ecosystem service oriented risk assessment combined with PSR were quantifying how urbanization influences the ecosystem services about Beijing-Tianjin-Hebei urban agglomeration of China between 2000 year and 2010 year. The mean value of ecosystem services in three gradient (rural areas, suburban, and urban area) declined from 4.12 Yuan/m2 to 1.75 Yuan/m(2) in 2000 year, while the mean value in 2010 year showed significant decrease and also represented urban-rural gradient. The average of pressure in PSR framework increased from 0.145 to 0.162 between two periods, while the average of status decrease from 0.378 to 0.311, and the status value decrease from 0.096 to 0.087. The higher risk degree V increased 6.95% between two periods, while the lower risk degree I decrease 6.89%. Two main types including high value gathering field and low value gathering field existed between two periods, the higher gathering field owned the ratio of 9.85%, mainly distributed around the urban area of Beijing and Tianjin, while the lower gathering field possess the ratio of 10.69%, mainly distributed in the northern and western in region. Overall, the analytical framework proposed in this study can provide comprehensive information to evaluate the impacts of complex practice in land-use planning and region ecosystem management.
