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。
Soil copper content is one of the key factors affecting tea quality. The spatial distribution and its influencing factors are revealed, which can provide theoretical guidance and regulation for tea production and quality improvement. Taking the typical tea plantations in Jiangsu and Zhejiang as an example, ArcGIS spatial analysis was used to comparatively analyze the spatial distribution characteristics of copper in topsoil of tea plantations in the typical areas of Jiangsu and Zhejiang. The results showed that the average level of Cu in tea plantation soils in Jiangsu and Zhejiang all met the relevant standards of tea plantation soil environmental quality, and all had strong spatial correlation. The copper content of soil in tea plantations in Jiangsu Province showed the clumpy distribution of the east and west of the clumps, the spatial differences were not obvious, a few areas appeared high values, which were greatly influenced by the regional factors. However, the copper content in Zhejiang tea gardens showed high density and concentric distribution, Significant spatial differentiation, the overall low concentration, with the exception of the terrain has a greater relevance, but also by a certain degree of human disturbance and the impact of small terrain climate.
