HUANG Chang-feng ,2,HE Lun-zhi1.( l.Institute of Eωnomic Research, Xinjiang University, Urumqi 830046, China; 2.School of Economics and Man鸣ement， Xinjiang Universi纱， Urumqi 830047, Ch恤a). China Environmental Science, 2012 ,32(2): 366-372 Abstract: This paper pointed out several m碍。r deficiencies in the 位aditiona1 model of relative c缸rying capacity of resources , such as efficiency ofresources using and difference of Iiving standards in different regions were not considered in the static analysis，由e reference area which included the study area was selec时as a sub吨t in the dynamic analysis. And it did some corresponding improvements by means of introduce correction factors, isolate 也e studyar，四合om 由e reference ar琶as and so on. Meanwhile， ωok the study of sustainable development of Chinese 28 provinces and cities in 2005 and Xinjiang from 2000 to 2007 as examples, used the modified model did static and dynamic anaIysis respectively. Among 28 provinces and cities during 2005，伽e number of provinces and cities which popu1ation stated overload, surplus was 18 and 10
