摘　　要：以秦岭火地塘林区 4个集水区径流水水质 1a监测结果为依据,在分析水质状况的基础上,运用模糊数学综合评价方法对其进行综合评价。结果表明,板桥沟集水区径流水水质属于I级水,火地沟集水区径流水水质属于II级水;火地沟和板桥沟,火地 1支沟和 2支沟集水区径流水中各指标浓度分别具有相同的变化规律;火地沟和板桥沟集水区径流水中Mg、Ca、NH+4 、细菌总数、总大肠菌群数指标浓度高于火地 1、2支沟,而K、CODcr、BOD5、NO-3 指标浓度则表现为相反的趋势。Based on the 1 year water quality and analysis monitoring among four watersheds in Huoditang forest region of Qinling mountains, this paper comprehensively evaluated the water quality by using fuzzy mathematics method. The evaluation results show that: the water quality in Banqiaogou watershed belongs to grade Ⅰ and that in Huodigou watershed belongs to grade Ⅱ. Most of the concentration indexes show similar characteristics between Huodigou branch 1 and 2. The concentrations of Mg,Ca,NH^+_4,total bacterial count, coliform bacteria are more in Huodigou and Banqiaogou watersheds than those in Huodigou branch 1 and 2 watersheds, The concentrations of K, CODcr, BOD_5, NO^-_3 are less in Huodigou and Banqiaogou watersheds than those in Huodigou branch 1 and 2 watersheds.
