This paper selects coal-base city,Qitaihe Cty of Heilongjiang Province as the study area and establishes the evaluation index system of intensive land use from a system point of view,combining the three aspects including economic,social and ecological benefit elements.Then we quantitatively calculated and analyzed degree of intensive land use of Qitaihe City from 2000 to 2008 using the multi-factor comprehensive evaluation method in this study.In this paper,we carried out the principal component analysis method to analyze the driving factors of intensive land use by using SPSS software.The results show that the degree of intensive land use took on an upward trend in Qitaihe City from 2000 to 2008.The level of intensive land use fell into band Ⅳ,and intensive land use was in not intensive state in 2000 and 2001.The level of intensive land use fell into band Ⅲ,and intensive land use was in the basic state from 2002 to 2006.The level of intensive land use fell into band Ⅱ,and intensive land use was in the intensive state in 2007 and 2008.Coal output,per capita GDP,urban land growth elasticity coefficient,allowed level of industrial waste water discharge and coal yield are the sensitive factors affecting intensive land use of the Qitaihe City.
