GIS支持下的福建省烤烟适宜地综合评价及其利用对策

GIS-Based Integrated Suitability Evaluation and Utilization Strategies of Land Resources for Flue-Cured Tobacco Production in Fujian

以福建省耕地为评价对象,借助GIS与数学模型对福建省烤烟用地适宜性进行综合评价。结果表明,福建省宜烤烟用地面积127.84万hm^2,占耕地总面积的93.24%。全省宜烤烟用地质量总体良好,全省最适宜烤烟用地面积33.20万hm^2、适宜面积88.69万hm^2,分别占宜烤烟用地总面积的25.97%和69.37%。烤烟最适宜区用地资源主要分布在南平、三明、漳州、泉州、福州和龙岩市,合计面积29.70万hm^2,占最适宜区总面积的89.45%1针对福建烤烟用地现状及其存在问题,提出烤烟用地可持续利用对策。

With the aid of GIS and relevant mathematic models, an integrated evaluation of the land resources in Fujian was performed for suitability of flue-cured tobacco production. Results showed that the total area of lands suitable for flue-cured tobacco production reached 127.84× 104 hm^2, accounting for 93.24% of the total area of the cultivated land in Fujian. On the whole the flue-cured tobacco suitable land was good in quality, and about 33.20 × 104hm^2 or 25.97% was high in suitability, and 88.69 × 104hm^2 or 69.37%, moderate in suitability. The land resources in the ＂High suitability＂ category were mainly distributed in six regions, such as Nanping, Sanming, Zhangzhou, Quanzhou, Fuzhou and Longyan, totaling up to 29.70 ×104hm^2, or 89,45% of the category. Aiming at the status quo of and existent problems with the flue-cured tobacco fields in Fujian, some strategies for sustainable utilization of the land resources are proposed.
