摘要：

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25.97 g/kg、1.61 g/kg、146.05 mg/kg、0.57 g/kg、28.80 mg/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16.34 g/kg、90.02 mg/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。

Abstract:

The spatial distribution characteristics of the representative tobacco-growing soil nutrients in Nanping areas were studied based on the status of the contents of the main nutrients and the platform of GIS, GPS and GS, and then the regional evaluation was made out. The results showed that the average contents of soil organic matter, total nitrogen, alkali-hydrolyzable nitrogen, phosphorus and available phosphorus were respectively 25.97 g/kg, 1.61 g/kg, 146.05 mg/kg, 0.57 g/kg and 28.80 mg/kg; the area, in which the content was above medium respectively accounted for 56.34%, 61.56%, 48.99%, 65.36% and 82.12% of the total cultivated area. The average contents of total and available potassium were respectively 16.34 g/kg and 90.02 mg/kg; the area, in which the content was above lower (besides the rich region) respectively accounted for 72.26% and 58.90%. Total phosphorus, available potassium and available phosphorus could be divided into three type regions, and others just two.
