Abstract: Impact of changes in land use on environment of resource-type cities is significant.In order to improve ecological benefit,researches have been conducted on response of the ecological carrying capacity of the cities to changes in land use,and variation of the integrated index of land use in Anshan,Fushun,and Benxi from 1996 to 2000.Results show a rising trend,though still quite normal,of the ecological carrying capacity of the three cities from 1996 to 2000.In 2000,the ecological carrying capacity of Anshan was 0.60,of Fushun 0.47,and of Benxi 0.49.Integrated index of the change in land use was 0.82 in Anshan,4.04 in Fushun,and 1.10 in Benxi.Anshan and Benxi were low,but Fushun high in land use intensity.Their ecological carrying capacity was positively correlated with their integrated index of the change in land use,basically forming a mode of mutual promotion.

Key words: ecological carrying capacity, integrated index of land use change, fuzzy comprehensive assessment
