The system of indexes is established with 29 indexes from natural resources, environmental quality, pollution management, and social and economy. And so is the five-grade criterion of assessment for some indexes with national criterion by referring the national one. The paper takes the average level of that of Shandong Province as a third-grade criterion , and does fifty percent, eighty percent of the third-grade one as a fourth-grades criterion.
