摘要
通过对安化黑茶产地的地质、地球化学特征系统研究,发现种植区的海拔、气候、土壤层等特征,适宜茶叶种植。本文探索性地将土壤环境指标与地球化学异常圈定方法相结合,对Pb、Zn、Cu、Hg、As环境指标进行分析统计,发现种植区内单项指标大部分区域满足二级标准。另外,综合指标评价存在22.13%的超标区域,应进行相关环境治理。
Through the study of geological and geochemical characteristics of Anhua black tea producing area,it is found that the elevation,climate and soil layer of planting area are suitable for tea planting.This paper tries to combine the environmental index and soil geochemical anomaly delineation method,statistical analysis of Pb,Zn,Cu,Hg.As environmental indicators,it is found that planting area of single index in most areas meet the two standards.In addition,there are over 22.13% of the comprehensive index evaluation areas should be related to environmental governance.
