By analysing pollutant source,pollutant characteristics and pollution route of ground water in mining area,as well as by determining proper evaluation factors of ground water pollution,this article makes respectively evaluation of single factor contamination index and composite evaluation of multi factors contamination index of the environmental quality status of ground water in tailings area.

This paper uses comprehensive assessment method of block grade to determine the appraisal factors, and uses comparison method to determine the weight of each factor, and finally determine the grade and order of undeveloped reserves.

The appraisal factors are divided to two types or special and ordinary factors,the ordinary factor is random selected under the prerequisite of special factor been assured,they are composed to the appraisal factor collection,the water quality is appraised with the fuzzy comprehensive appraisal method,the appraisal result is received according to the probability.

We selected DO,CODcr,P and Ammonia nitrogen as evaluation factor according to monitoring data of Fu River and characteristic of water quality evaluation.

Guided by the Universal Soil Loss Equation and the unique geographic features of Ji nan City,primary evaluation factors for the sensitivity of soil erosion in Ji nan City are determined,including precipitation,terrain undulation,soil quality,and vegetation.

At last,evaluation factor of distributed SPR sensor was presented,which will be helpful to the design,fabrication and evaluation of distributed SPR sensor.

Based on the evaluating factors of mining geological environment such as existing environment,geological environment and mineral resources of mining areas and more or less inconvenience of environment recovey of mining areas,it can iris out the isolines of environmental quality index by using the model of weighted index and the estimation and superposition of the factors.
