云南省茶叶生产的时空格局演变特征分析
Analysis of Spatiotemporal Pattern Evolution Characteristics of Tea Production in Yunnan Province
【摘要】 利用1990─2020年云南省茶叶生产数据,采用对数平均迪式分解法、空间基尼系数、赫芬达尔指数、产业集中度和重心模型等,分析了云南省茶叶生产的时空演变特征,并探讨了云南省茶叶产量重心的迁移轨迹。研究结果表明:(1)云南省茶叶种植面积经历了波动下降、波动增长和稳定增长3个阶段,茶叶产量则经历了缓慢增长、快速增长和稳步增长3个阶段;(2)茶叶种植面积增长是云南省茶叶产量增长的主导因素,单产水平提升是次要因素;(3)云南省茶叶产业发展迅速,但地区间差异较明显,基本形成了以临沧市、普洱市和西双版纳州3个州(市)为主的核心茶区,以凤庆县、勐海县、景洪市、昌宁县、澜沧县5个县(市)为主的重点茶区的发展格局;(4)云南省茶叶产量重心的迁移经历了向东南─西南─西北─东南4个方向的阶段变化,迁移速度经历了快─慢─慢─慢4个阶段的变化。根据上述研究结果,提出了关于云南省茶叶产业高质量发展的对策建议。
【Abstract】 Based on data on tea production in Yunnan Province from 1990 to 2020, this study empirically analyzed the spatiotemporal evolution characteristics of tea production in Yunnan Province by measures such as logarithmic mean Dirichlet decomposition, spatial Gini coefficient, Huffindal index, industrial concentration, and gravity center model, and explored the trajectory of the shift of tea yield gravity center in Yunnan Province. The research results show that:(1) The tea planting area in Yunnan Province has gone through three stages: fluctuating decline, fluctuating growth, and stable growth. The tea production has gone through three stages: slow growth, rapid growth, and steady growth.(2) The growth of tea planting area is the leading factor in the growth of tea production in Yunnan Province, while the increase in yield per unit area is the secondary factor.(3) The tea industry in Yunnan Province has developed rapidly, but there are significant regional differences. It has basically formed a core tea area mainly composed of three states(cities): Lincang City, Pu’er City and Xishuangbanna Prefecture, and a key tea area mainly composed of five counties(cities): Fengqing County, Menghai County, Jinghong City, Changning County and Lancang County.(4)The migration of the tea yield gravity center in Yunnan Province has undergone four stages of “southeast-southwest-northwestsoutheast”, and the migration speed has gone through four modes of “fast-slow-slow-slow”. According to the above results, the countermeasures and suggestions on the high-quality development of tea industry in Yunnan Province were put forward.
