为摸清湘西植烟土壤有效铜含量分布状况,测试了湘西主要烟区488个土壤样本的有效铜含量,并采用传统统计学和地统计学方法分析了湘西植烟土壤有效铜含量适宜样本分布、县域差异、土壤类型差异、海拔差异及空间分布.结果显示:①湘西植烟土壤有效铜含量总体上属偏高水平,平均值为2.125 mg/kg,变幅为0.024～7.840 mg/kg,变异系数为69.98％,处于适宜范围内的样本占13.81％.②不同县之间的植烟土壤有效铜含量差异达极显著水平,按从高到低依次为:凤凰县＞花垣县＞泸溪县＞保靖县＞古丈县＞永顺县＞龙山县.③不同土壤类型土壤有效铜含量差异极显著,按从高到低依次为:水稻土＞红灰土＞黄棕壤＞黄壤＞红壤...

In order to understand the distribution of available copper contents in tobacco growing soils in Xiangxi, distribution frequency of available copper contents among different counties, soil types, altitudes were analyzed by both classic statistics and geostatistics with 488 soil samples. The results were as fol lows;（1） Available copper contents in the tobacco soils were little higher with a mean of 2. 125 mg/kg, range of 0. 024-7. 840 mg/kg and variation coefficient of 69.98%. About 13.81% of the soil samples from available copper contents we...
