摘要
为我国茶产业的持续健康发展提供依据,采用对数平均迪氏指数法(LMDI)对1997—2015年我国茶叶产量变化影响因素及茶叶生产时空变化进行分析。结果表明:19年间我国茶园种植面积、产量和单产均呈波动递增态势。茶园种植面积和单产对茶叶增产贡献程度呈显著差异,在时序维度上两者对产量增加的累计贡献均表现为正效应,且前者贡献程度远大于后者;在空间维度上,总贡献值区域差异显著,且大部分产区主要依靠扩大种植面积来增加产量,少数产区主要依靠提高单产来增加产量。
To provide a basis for sustainable healthy development of tea production in China,the method of logarithmic mean divisia index(LMDI)was employed to analyze the influencing factors of tea yield variation,and its temporal and spatial variation in China during 1997-2015.Results:The tea planting area,production and yield all fluctuatingly increased during the 19 years.The contribution degree influencing tea production variation between tea planting area and yield are significantly different.The cumulative contribution of them have positive effects on tea production variation,and the former is much larger than the latter in the time dimension.The total contribution value are significantly different among the producing areas of Chinese tea in the spatial dimension,and most of the producing areas depend on increasing planting area to increase tea production,only a few depend on increasing yield to increase tea production.
