摘要：

通过采集、测定南平烟区代表性植烟土壤中、微量元素含量状况，借助GIS、GPS与地统计学模型（Geo-statistic）集成，研究其空间分布状况，并作出分区评价。结果表明：土壤有效锌、水溶性氯平均含量分别为2.55 mg/kg、20.22 mg/kg，含量中等以上面积分别占总耕地面积的94.71%、45.15%；交换性钙平均含量分别为531.69 mg/kg，含量较低和中等的面积占93.68%；交换性镁平均含量80.09 mg/kg，丰富面积占70.61%；有效硫平均含量35.30 mg/kg，含量中等以上面积占89.45%；有效硼平均含量0.26 mg/kg，含量低值面积占64.60%。交换性钙和有效锌可划分为2个类区，水溶性氯可划分为4个类区，交换性镁和有效硫、有效硼则可划分为3个类区。同时，根据土壤碱解氮、速效磷和水溶性氯等主要养分的分布分区状况和丰缺程度，提出了8个施肥分区和5个烤烟专用肥分区，并根据每个分区的特点给出了相应的专用肥配方建议，实现烤烟统一、简化施肥。

Abstract:

The spatial distribution characteristics of the representative tobacco-growing The spatial distribution characteristics of the representative tobacco-growing soil nutrients in Nanping areas were studied based on the status of the contents of medium and microelements and the platform of GIS, GPS and GS, and then the regional evaluation was made out. The results showed that the average contents of available zinc and water soluble chloride were respectively 2.55 mg/kg and 20.22 mg/kg, the area, in which the content was above medium respectively accounted for 94.71% and 45.15% of the total cultivated area, the average contents of exchangeable calcium was 531.69 mg/kg, the area, in which the content was lower or medium accounted for 93.68%, exchangeable magnesium was 80.09 mg/kg, the area, in which the content was rich accounted for 70.61%, available sulfur was 35.30 mg/kg, the area, in which the content was above medium accounted for 89.45%, available boron was 0.26mg/kg, the area, in which the content was low accounted for 64.60%. Exchangeable calcium and available zinc could be divided into two type regions, water soluble chloride could be divided into four type regions, and exchangeable magnesium, available sulfur and boron could be divided into three type regions. According to the content of alkali-hydrolysable nitrogen, available phosphorus and water soluble chloride in soil and distribution conditions of these nutrients, eight fertilization regions and five special compounding fertilization regions could be defined, and according to the characteristics of each regions, its corresponding special fertilizer formulations, in order to realize the unified and simplified fertilization.
