中文摘要：
以国家土壤环境质量标准（GB15618—1995）中的二级标准和有机茶产地环境条件（NY5199—2002）作为评价标准，采用单因子污染指数法和综合污染指数法对四川省两名优茶产地茶园土壤中的8项重金属元素进行对比．得出茶园A土壤环境明显优于茶园B。结合茶园所采集茶叶样品的感官评价．认为优良的土壤环境可以种植出更优质的茶叶。利用茶园A，B现有数据建立回归模型，可对类似的土壤进行适宜性评价，推断土壤是否适合种植茶叶以及茶叶品质如何。
英文摘要：
Eight heavy metals in the soil are compared at two famous tea production areas in Sichuan Province by contamination index on individual and integration factors under the standard of state soil quality （GB15618-1995） and the condition of organic tea production areas（NY5199-2002） respectively. Based on the result of the comparison and sense judgement of tea leaves, the quality of soil in tea garden A is found better than that in B obviously and high-quality tea leaves are cultivated in high-quality soil. The model of the regression analysis is established by using data from A and B to forecast the quality of tea plantation in the soil.
