基于GIS技术的福建省光泽县烟草用地适宜性评价

    GIS-Based suitability evaluation of land resources for tobacco production of Guangze in Fujian province

    • 摘要: 烟草是光泽县重要的经济作物之一,气候尧土壤尧地形条件等生态环境对烟草的产量和品质具有重要影响。以福建省光泽县耕地为评价对象,综合考虑气候尧土壤尧地形条件等15 个评价指标,借助GIS 与数学模型对光泽县烟草用地适宜性进行评价。结果表明,光泽县宜烟草用地面积15 402.95 hm2,占耕地总面积的94.35%,全县宜烟草用地质量总体良好,其中高度适宜烟草用地面积3 774.76 hm2,中度适宜面积9 134.77 hm2,分别占宜烟草用地总面积24.51%和59.31%;烟草高度适宜区用地资源主要分布在鸾凤乡尧止马镇尧寨里镇尧李坊乡和崇仁乡,面积共3 468.97 hm2,占全县高度适宜总面积的91.89%。利用光泽县烟草用地适宜性等级空间分布分析结果,可为该县烟区更加合理优化布局,提高优质烟叶生产能力提供科学的指导。

       

      Abstract: Tobacco is one of the important economic crops in Guangze ,the ecological environment of climate,soil and landform has important effects on the yield and quality of tobacco.With the aid of GIS and relevant mathematic models,an integrated evalution of the land resources in Guangze of fujian province was performed for suitability of tobacco production by choosing 15 evaluation indexes from 3 respects of climate, soil and landform. Results showed that the total area of lands suitable for flue-cured tobacco production reached 15402.95 hm2, accounting for 94.35% of the total area of the cultivated land in Guangze,On the whole the flue-cured tobacco suitable land was good in quality,and about 3774.76 hm2 or 24.51% was high in suitability,and 9134.77 hm2 or 59.31% ,moderate in suitability.The land resources in the 野High suitability冶 category were mainly distributed in fine regions,such as Luanfeng, Zhima, Zhaili, Lifang and Chongren,totaling up to 3468.97 hm2, or 91.89% of the category.According to the spatial distribution analysis of suitability evaluation for tobacco production in Guangze,it can provide scientific guidance of building more reasonable area and improving the capacity of high-quality tobacco production .
