Abstract
Trends in environmental variables are often investigated within a study region at more than one site. At each site, a trend analysis determines whether a trend has occurred. Yet often also of interest is whether a consistent trend is evident throughout the entire region. This paper adapts the Seasonal Kendall trend test to determine whether a consistent regional trend occurs in environmental variables.
摘要
环境变量的趋势通常在研究区域内的多个地点进行调查。在每个地点，趋势分析确定是否出现了趋势。然而，整个区域是否存在一致的趋势往往也很受关注。本文采用季节性肯德尔趋势检验来确定环境变量是否存在一致的区域趋势。
