中文摘要：

土壤铜含量是影响茶叶质量的关键性因素之一,对其空间分布规律及其影响因素加以揭示,可为茶叶生产与品质提升提供理论指导与调控建议。以江浙典型茶园为例,运用Arc GIS空间分析功能,对比分析江浙典型地区茶园表层土壤铜的空间分异特征。结果表明：江浙茶园土壤铜的平均水平均符合茶园土壤环境质量的相关标准,且都具有强烈的空间相关性。江苏茶园土壤铜含量呈现西密东疏的团块状分布,空间分异不明显,少数区域出现高值,受区域因素的影响较大;而浙江茶园铜含量呈现高密度多同心圆状分布,空间分异显著,总体集中偏低,除与地势有较大关联性外,还受到一定程度的人为活动的干扰以及小地形气候的影响。

英文摘要：

The copper content in soil is one of the key factors influencing the quality of tea. It is necessary to reveal its spatial distribution pattern and influencing factors in order to provide the theoretical guidance and proposal of regulation to improve the yield and quality of tea. By using spatial analysis function of Arc GIS, this article compared and analyzed the spatial differential features of copper in surface soil of different regions, taking typical tea gardens in Jiangsu and Zhejiang provinces as examples. Results showed that the average level of copper in tea garden soils of Jiangsu and Zhejiang provinces met standards of environmental condition for pollution-free tea production area and organic tea production area, and both of Jiangsu and Zhejiang provinces were spatial autocorrelation strongly. The distribution of the copper content in soil of Jiangsu province, which was dense in the west and sparse in the east, was agglomerated with faint spatial variability, mainly because of the regional factors, along with heavy copper contents in fewer areas. The distribution of the copper content in soil of Zhejiang presented concentric rings in the high density with obvious spatial variability and low overall level. Except for the close correlation with the terrain slope, it was because of the effects of human activities and the microclimate.
