| 摘 要： | 安吉白茶是浙江安吉特色农业的重要支柱之一, 对浙江安吉茶园格局动态变化规律的探究, 有利于区域茶产业的优化调整和可持续发展。本研究基于安吉2012、2016和2020年土地利用相关数据, 运用土地利用动态度指数、土地利用拓展程度综合指数和土地利用转移矩阵等方法, 对浙江安吉2012-2020年茶园格局进行动态变化过程和差异性特征研究分析。结果表明: 2012-2020年安吉县域茶园格局动态变化存在明显的时空差异；（1）从转移数量和空间分布来看, 2012-2016年茶园土地转移数量极少, 茶园面积基本稳定, 空间分布较为零散; 而2016-2020年茶园面积明显增长, 且新增茶园分布相对集中。（2）从转移过程来看, 2016-2020年较之2012-2016年更为强烈, 转移数量显著增加, 且转移过程导致茶园空间分布更为集中。（3）从转移类型来看, 2012-2016年茶园主要转为耕地, 几乎无转入, 转移类型较为单一; 而2016-2020年, 茶园主要转为林地、园地和建设用地, 转入主要是林地、耕地和园地, 转移类型多样。以上结果明晰了浙江安吉2012-2020年茶园格局的时空动态变化特征, 为区域茶园时空动态变化研究和未来可持续发展规划提供了数据基础和科学指导。

| Abstract: | Anji White Tea is one of the important productions of specialty agriculture in Anji, Zhejiang. Understanding the spatiotemporal dynamic of these tea plantations will promote the local tea industry and regional sustainable development. This study analyzed the spatiotemporal dynamic change and of the tea plantation in Anji from 2012 to 2020 by comparing the land use dynamic index, comprehensive index of land use expansion degree and land use transfer matrix based on land use data at 2012, 2016 and 2020.The results showed that there were obvious temporal and spatial differences in the pattern of tea plantations from 2012 to 2020. The spatial pattern was stronger changed during 2016-2020 than 2012-2016. The amount of land transformation of tea plantations from 2012 to 2016 was very small, with relatively stable area variation and discrete spatial distribution. However, the area of tea plantations increased significantly during 2012-2016, and the new tea plantations were relatively clustering, while the discrete and small tea plantations were disappeared. The intense of land transformation during 2016-2020 was much higher than that during 2012-2016, with more land transformation cases leading to more clustering spatial distribution of tea plantations. Tea plantations were mainly converted to cropland from 2012 to 2016, but less converted from other land use types. During 2016-2020, the land transformation of tea plantation was referred to various other types. Tea plantations were mainly converted into forest, garden and construction land, and converted from forest, cropland and garden. The present study clarified the spatiotemporal dynamic process and difference characteristics of the spatial pattern tea plantation in Anji, and provides basic database and scientific guidance for the future sustainable development planning of tea plantation in future. |
