Forest ecosystem plays an important role in supplying and maintaining ecosystem services in the situation of rapid economic development in Shandong province. Forest ecosystem services are divided into four facets: production, recreation, air quality improvement and water-soil conservation in this paper. Forest ecosystem services’ values of the different counties are accounted using the eco-economy evaluation methods. Based on the forest ecosystem services’ values and mechanism analysis, an integrated assessment index system has been established, which consists of six indexes. The integrated assessment index system describes the services at three aspects such as structure, density, and quality. Using the Polygon Synthesis Indicator method, each country gets an score of integrated assessment. As a result, only 0.39percent of the total area in Shandong province scores from 0.75 to 1 (gradeⅠ), 2.37 percent scores from 0. 5 to 0.75 (gradeⅡ), 41.65 percent scores from 0.25 to 0.5 (grade Ⅲ), and 55.59 percent scores from 0 to 0.25 (grade Ⅳ). The results indicates that the forest ecosystem services of most countries in Shandong province is poor. According to the integrated assessment, some advices are proposed.
