曲靖烟区烤烟大田期38年降雨量变化时空特征分析
Analysis on Temporal and Spatial Change Characteristics of Precipitation at Flue -cured Tobacco Growth Stage over 38 Years in Qujing
摘要
Abstract
According to the precipitation data provided by 9 weather stations in Qujing tobacco area from 1971 to 2008, the temporal and spatial characteristics and changing laws of the precipitation in Qujing were studied by using linear trend analysis, moving t - test and wavelet analysis. The results showed that: within the 38 years, the precipitation in flue - cured tobacco growth period, root extending period and mature period appeared a decreasing trend, but that in vigorous growing period appeared an increasing tendency. Before 1988, the precipitation mainly existed the short period of 6 years, after 1989 it mostly existed the long period of 16 years, and the abrupt change of the precipitation occurred in the years 1988 and 2003. The precipitation in different areas had the following order; South - east tobacco area > South - west tobacco area > Eastern tobacco area > Central tobacco area > North - west tobacco area. The precipitation was the highest in low-altitude area, higher in medium -altitude area, and the lowest in high -altitude area.关键词
