摘 要：
在保山烟区定位采集土壤样品124个,采用经典统计学和地统计学相结合的方法研究了区域植烟土壤主要养分的描述性统计特征、空间变异和丰缺格局。结果表明:植烟土壤有效硼和有效锌含量平均值分别为0.45 mg/kg和1.97 mg/kg,均表现为中等程度的变异;土壤有效硼和有效锌块金效应分别为46.58%和39.87%,表现为中等的空间相关性,空间变异受结构性因素和随机性因素的影响;土壤有效硼含量较低,64.37%面积的土壤有效硼缺乏;有效锌含量中等,40.58%面积土壤有效锌缺乏。

摘 要：
124 tobacco soil samples were collected based on GIS technique in Baoshan tobacco growing areas,the descriptive analysis characteristics,spatial variability of soil available B and available Zn were studied. The results showed that the average contents of soil available B and available Zn were0. 45 mg / kg and 1. 97 mg / kg,with a moderate degree of variance. The nugget effect of available B and Zn were 46. 58% and 39. 87%,with a moderate spatial dependence,structural factors and random factors caused the spatial variability of available B and Zn. Spatial distribution maps showed that available B was low,64. 37% of the area was extremely deficient of available B; and available Zn was moderate,40. 58% of the area was extremely deficient of available Zn.
