云南烟区不同海拔高度区间烤烟气象因子分析

本研究利用云南省烤烟种植区1994年至2004年逐月气象数据,初步分析了91个气象站主要气象因子与站点海拔高度的相关关系,其中1~12月平均气温、平均风速和平均地面温度与海拔高度的相关均达到极显著水平,部分月份的降水量、日照时数、蒸发量和平均相对湿度与海拔高度的相关达到显著水平和极显著水平。利用5~9月影响烤烟生长的主要气象因子构建出海拔高度的回归模型,经过检验估测效果较好,筛选出与海拔高度关系密切的气象因子为:8月平均气温、5月日照时数、5月降水量。结合这些气象因子分布范围和对烤烟生长的影响初步进行区间划分,最终把估测出的海拔高度初步分为,低于809.75 m,809.75~1297.95...

The meteorological data each month from 1994 to 2004 in Yunnan tobacco growing area were used to analyze preliminarily the relationship between main meteorological factors and the altitude in 91 weather stations.The correlation between monthly average atmospheric temperature,average wind velocities,average ground temperature from January to December and altitudes were significant(P0.01).The correlation between part month precipitation,sunlight hours,evaporation,average relative humidity and altitudes reached significant levels(P0.05) and a very significant level(P0.01).The regression model was constructed by main meteorological factors affecting flue-cured tobacco growth from May to September,and it had good estimating effects through checking up.The main meteorological factors were screened out
