唐代茶叶种植地域变化的探究--基于GIS制图技术的分析

Research on the Change of Tea Planting Area in the Tang Dynasty Based on GIS Mapping Technology

从初唐至晚唐,唐代茶产业迅速发展,茶税、榷茶制度以及贡茶制度随之应运而生,茶叶种植地域亦逐渐扩大,范围涉及甚广。学术界对唐代茶区的研究成果较多,但多有缺漏,且基于唐代茶叶种植地域变化,探究其变化规律的研究尚属空白。本文基于前人学术成果,辨析更新并运用GIS制图技术以探究唐代茶叶种植区域的动态变化过程,认为唐代前后种植区域差异显著,晚唐产茶州较盛唐产茶州分布更为密集且范围更大,种植地域稳步扩张,基本覆盖现今四大茶区,唐代茶叶种植地域呈现聚集到分散、单一长江流域到全国各水系流域、纬度范围逐步扩大、初步形成到全面形成现今四大茶区的变化规律。

From the early to the late Tang Dynasty,the tea industry developed rapidly.The tea tax,tea monopoly system,and tribute tea system came into being,as the tea planting area gradually expanded,covering a wide range.There are many research achievements about the tea area of the Tang Dynasty in academia,but with many deficiencies,and the research on the changes based on the regional changes of tea planting in the Tang Dynasty is still blank.Based on previous academic achievements,this paper integrates,analyzes,and uses GIS mapping to explore the dynamic changes of tea planting areas in the Tang Dynasty.It is believed that there are significant differences in the planting areas before and after the Tang Dynasty.Tea-producing areas in the late Tang Dynasty were denser and wider than those in the prosperous Tang Dynasty,and the planting areas expanded steadily,basically covering the four major tea areas today.The tea planting areas in the Tang Dynasty show a change rule of gathering to dispersing,single Yangtze River basin to various river basins in China,gradually expanding the latitude range,and initially forming the four major tea areas today.
