湖南省基本烟田评价指标体系及适宜性评价研究——以湘南丘陵烟草种植区为例

Study on Evaluation Index and Suitability Evaluation of Basic Tobacco Field in Hunan——A Case Study of Hilly Tobbaco Planting Region in South Hunan

以湘南丘陵烟草种植区为例,系统介绍了基本烟田适宜性评价指标体系的选择原则、方法和评价依据,以此为依据,采用层次分析法对湘南烟区基本烟田进行了适宜性评价。结果表明:湘南丘陵烟区共有基本烟田55万hm2,该区烟田总体上能适宜于烟叶优质适产的需要,最适宜的烟田占45.8%;适宜的烟田占38.2%;次适宜的烟田为13.2%;不适宜的烟田只占2.8%,少量相对不适宜烟田主要是因为存在个别限制因子,适当加以改造缓解或消除,可以使之成为适宜烟田。

The selective principle, methods and evaluation basis of suitability evaluation system for basic tobacco field were systematically introduced in this paper. The hilly tobacco planting region in south Hunan was taken as an example, and the suitability of which was evaluated by analytic hierarchy process （AHP）. The results indicated that as follows： there were 55 ten thousand hectare basic tobacco field in south Hunan, most of them could meet the requirement of tobacco leaves with high-quality and high-yield; the most optimum tobacco field accounted for 45.8% of total amount; the optimum tobacco field accounted for 38.2%; the sub-suitable tobacco field accounted for 13.2%, and the unsuited tobacco field accounted for 2.8%. There were a few relatively unsuited tobacco fields because of the individual limiting factors, but as long as properly reform, modify or eliminate these limiting factors, these relatively unsuited tobacco fields could become to optimum tobacco fields.
