| 摘 要： | 在分析河南省南阳市烤烟种植区各项土壤肥力指标的基础上,建立了烤烟土壤肥力适宜性评价指标体系。运用模糊数学和层次分析法对土壤肥力水平进行了综合评价、分级。采用地理信息系统软件mapGIS绘制河南省南阳市烤烟种植区土壤肥力评价图。结果表明,唐河、方城和内乡的东南部由于植烟田土壤有机质含量和K含量高,为土壤适宜性较高地区;西峡、淅川、邓州和内乡的西部植烟田虽然土壤中有机质和含N量较高,但Cl-含量也比较高,为次适宜区。今后应注意改良土壤,加强N、P、K搭配比例的协调。图2,表3,参15。

| Abstract: | Based on analysis of the physical and chemical properties of soil samples collected from Nanyang tobacco planting regions in Henan province,an index system of soil fertility suitability of tobacco was established in this paper.The fertility level was evaluated and classified by fuzzy and AHP analysis.And the fertility map of Nanyang tobacco planting regions in Henan province was generated with GIS software MapGIS.It is found that the area of higher soil fertility suitability accounts for 46.6%,while the area of less suitability accounts for 43.2%.The main constraints are too high Cl-contents and pH value. |
