摘　　要：土壤环境质量的好坏直接关系到人类的生存和发展,及时开展土壤环境质量评价并据此制定针对性的控制对策和措施具有重要意义。目前,用于评价土壤环境质量的方法较多,但评价结果的准确性和客观性还有待提高。综合标识指数法已在我国河流水质评价中得以成功应用,鉴于该方法既可给出待评价样本的环境质量等级,又可表达其单项指标超标的个数和整体是否满足给定环境质量目标的情况,将引入并应用于某地区的土壤环境质量评价。结果表明,该方法评价结果至少与2种及以上其他评价方法的评价结果一致,具有较高的可靠性。Assessing the quality of soil environmental and formulating specific control measures at appropriate time is essential, since the soil environmental is of great importance for survival and development of human beings. There are now many methods to evaluate the soil quality, but both the accuracy and objectivity of them should be improved. The comprehensive identification index method has already been successful- ly adopted in the evaluation of river water quality, it not only gives the environmental quality level, but also makes clear the number of indexes exceeding the standards. Thus the method of comprehensive identification method is introduced to the soil environmental quality assessment in some areas. The results show that it agrees with more than two decisions made by other methods, indicating that is is of hizh reliabilitv.
