Research of city´s Resource Environmental Bearing Capacity based on set pair analysis—A study in Daqing

In the guidance of conceptual of resource environment al bearing capacity (REBC), evaluation index system was constructed from 4 aspects including resource subsystem, environment subsystem, adjustment subsystem and social-economic subsystem. Set pair analysis based on entropy-AHP method was used to assess the index system of Daqing City, Results indicated that bearing capacity index in status quo showed Zhaozhou and Zhaoyuan, county of Daqing were in the poor state, and should be fallen into the focus area of resource environmental protection. Although the whole bearing situation improved from 1980s to the present, environment subsystem was deteriorating, environmental protection should be paid particular attentions. The improved measures of regional REBC were presented based on analysis of extent of opposition and homology.
