In this paper, change of land cover and use type was first studied through interpretation of the two images (2007 and 2018), and then, dynamic evaluation of ecological service value in Southern Mountainous Areas of Jinan was made with evaluation system and equivalent factors built by Xie GD based on Costanza’s system. The results revealed that the area of bare land and grass land decreased by 4875.48 hm2 and 55141.56 hm2 respectively, on the contrary, cultivated land, forestland and building land has increased by 26915.671 hm2, 32261.31 hm2 and 1442.16 hm2 respectively. The ecological service value showed the increasing trend generally, among of which water conservation, air regulation, land protection, recreation have increased distinctly, which can be explained that the control develop strategies had taken action actively.
