Improving land eco-efficiency is one of the important ways of land effective-use in Coal City. Taking the coal city(Hegang city in Heilongjiang)for example, according to the ecological status of land use, resource development status,and its economic development stage, this paper builds eco-efficiency evaluation index system of land in Hegang city choosing 24 representative indicators from the aspects of ecological carrying capacity of land,ecological status of land and ecological response of land, etc. and quantitatively evaluates and analyzes the eco-efficiency of land in Hegang city from 2001 to 2007 adopting comprehensive evaluation method and coordination degree analysis method. The results showed that from 2001 to 2007, the coordination degree of land ecosystem and land ecological comprehensive benefits had an orderly increase in positive correlation in Hegang city. From 2001 to 2003, the land ecosystem was in the uncoordinated state in Hegang city. From 2004 to 2006, the ecological status of land was in the basic coordination state in Hegang city. In 2007, land ecosystem was harmonious in Hegang city.From 2001 to 2007, in Hegang city, the comprehensive evaluation values of eco-benefits of land were ranging from 0.10 to 0.21 with a minor rise but still at an extremely low level. Thus, there is still much room for improvement on the eco-benefits level of land in Hegang, and the comprehensive eco-benefits of regional land can be improved by raising the coordination degree of land eco-benefits.
