|The composition of the evaluation index of theecosystem status evaluationand comparative analysis of Ecological Index impact factors in new and old codes are briefly described.Correlation analysis of the evaluation of the ecosystem status and impact factors in Shandong Province at the city and county levels from 2014 to 2017 shows that，after the implementation of the new technical criterion, the EI evaluation results were improved with the increasing of forestland area, shrubbery area, lake(reservoir) area, paddy field area, moderate and severe erosion area. At the same time, the increases of other construction land area and saline alkali land area have had a negative impact on the EI evaluation results. The influences of the eight impact factors on the county level EI results were significantly greater than that on the city level EI results. The influences on the evaluation results of city level EI and county level EI were different with the increasing of urban construction land area, but the negative impacts were all reduced in the new technical criterion. Compared with the trialtechnical criterion, the negative impacts of SO2 emissions on the evaluation results of city level EI were significantly reduced, while the negative impacts on the evaluation results of county level EI were significantly increased.
