通过采集、测定南平烟区代表性植烟土壤主要养分含量状况,借助GIS、GPS与地统计学模型(Geo-statistic)集成,研究植烟土壤主要养分空间分布状况,并对其作出分区评价。结果表明:土壤有机质、全氮、碱解氮、全磷、速效磷平均含量分别为25.97g/kg、1.61g/kg、146.05mg/kg、0.57g/kg、28.80mg/kg,含量中等以上面积分别占总耕地面积的56.34%、61.56%、48.99%、65.36%、82.12%;全钾、速效钾平均含量分别为16.34g/kg、90.02mg/kg,含量较低以上面积(没有丰富区)分别占72.26%、58.90%。全磷、速效磷、速效钾可划分为3个类区,其他养分则可划分为2个类区。
By collecting and measuring the main nutrient contents of the representative tobacco-growing soil in Nanping tobacco-growing area, the spatial distribution of main nutrients in tobacco soil was studied by means of GIS, GPS and Geo-statistic, and the zoning evaluation was made. The results showed that the average contents of soil organic matter, total nitrogen, available nitrogen, total phosphorus and available phosphorus were 25.97g / kg, 1.61g / kg, 146.05mg / kg, 0.57g / kg and 28.80mg / Accounting for 56.34%, 61.56%, 48.99%, 65.36% and 82.12% of the total cultivated area respectively. The average contents of total potassium and available potassium were 16.34g / kg and 90.02mg / kg, respectively. ) Accounted for 72.26% and 58.90% respectively. Total phosphorus, available phosphorus, available potassium can be divided into three categories, other nutrients can be divided into two categories.
