【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。
[Abstract]:Soil copper content is one of the key factors affecting the quality of tea. To reveal its spatial distribution and its influencing factors can provide theoretical guidance and regulation suggestions for tea production and quality improvement. Taking typical tea plantations in Jiangsu and Zhejiang provinces as an example, the spatial differentiation characteristics of copper in topsoil of tea plantations in typical areas of Jiangsu and Zhejiang provinces were analyzed by using the spatial analysis function of Arc GIS. The results showed that the average level of soil copper in Jiangsu and Zhejiang tea plantations met the relevant standards of soil environmental quality of tea plantations and had strong spatial correlation. The copper content of tea garden soil in Jiangsu Province was distributed in the form of lumpy and sparsely spacial differentiation was not obvious, a few areas appeared high value, which was influenced by regional factors, while the copper content of tea garden in Zhejiang Province showed high density and polyconcentric circular distribution, and the content of copper in tea garden in Zhejiang Province showed high density and polyconcentric circular distribution. The spatial differentiation is significant and the overall concentration is low. In addition to being related to the topography, it is also affected by the disturbance of human activities and the small topographic climate to a certain extent.
