Research on Changes and Influencing Factors of China's Tea Production Pattern
Based on panel data on Chinese tea production from 1985 to 2021,this study employs GIS spatial analysis and multi-scale geographically weighted regression(MGWR)models to explore the spatiotemporal evolu-tion characteristics and influencing factors of China's tea production patterns.The results show that:(1)From 1985 to 2021,China's tea production scale has continuously expanded,with the production center gradually shift-ing westward.There are significant positive scale effects in spatial agglomeration,with tea regions in Jiangnan,South China,and Southwest China mainly characterized by"high-high"and"low-high"agglomerations.In con-trast,the Jiangbei tea region shows no agglomeration characteristics,highlighting spatial polarization.(2)The dominant factors influencing the changes in China's tea production patterns vary significantly across different peri-ods.In 1995,effective irrigation area and fertilizer input were the main factors.By 2010,the impact of precipitati-on,sunlight hours,and affected disaster area gradually became prominent.After 2020,transportation level emerged as a significant driving factor,but effective irrigation has consistently remained the primary driver of chan-ges in tea production patterns.
