Abstract: Abstract：The accelerated process of urbanization and economy inevitably impacts the ecological environment, affects the function of traditional eco-environment, and destroys the harmony of human beings and nature. Eco-environmental bearing capacity is an important application direction of sustainable development research, and also the embodiment of the construction of ecological civilization. In this paper，the evaluation index system of eco-environmental carrying capacity of Shandong peninsula was established. In combination with actual conditions and characteristics based on the principle of establishing the evaluation index system, the evaluation index system was divided into four primary indexes：natural environment, ecological environment, population environment, and contaminated environment, and then the evaluation index system constructed 17 typical evaluation indexes as secondary indexes that we chose from the primary indexes, with the weight of each evaluation index determined by AHP. The authors adopted fuzzy comprehensive judgment to assess the eco-environment carrying capacity of six cities in Shandong peninsula at the present stage, and the results show that Weihai City is of the first rate，Qingdao, Yantai, Rizhao are of the second rate, Weifang City is of the third rate, and Dongying City is of the lowest rate. Based on the evaluation results and analysis of each city, the authors provide the scientific basis for the eco-civilization construction.
