摘要
[目的]通过对陇县地区的气候、土壤条件进行研究,选择6个主要影响烤烟种植的评价指标并进行分析,充分挖掘优质烤烟生长的资源环境,为陇县地区烤烟种植发展规划提供科学依据。[方法]利用陇县气象局1981~2015年气象观测资料及14个乡镇区域自动站2007~2015年气温、降水资料,进行烤烟生态气候适宜性分析,确定区划指标,采取模糊数学方法建立指标隶属函数进行分区。[结果]陇县北部及中部海拔1 000~1 300 m的地区,是陇县烤烟最适宜种植区,也是优质烤烟的主产区。中部海拔较低的川道地带也是烤烟的适宜种植区。[结论]利用GIS技术,在实现区划指标空间化基础上,完成了陇县烤烟种植的适宜性区划并制作出区划图。
[Objective] Through studying on climate and soil conditions in Longxian,6 evaluation indicators influencing flue-cured tobacco planting were selected and analyzed,the resource environment for the growth of high quality flue-cured tobacco was fully exploited,which will provide scientific basis for flue-cured tobacco planting. [Method] Adopting observation data of 1981-2015 from Longxian Meteorological Bureau and temperature,precipitation data from 14 villages automatic station during 2007-2015,the ecological and climatic suitability was analyzed,zoning indicators were determined,fuzzy mathematics method was used to establish the membership function for zoning. [Result]1 000-1 300 m area in northern and central Longxian is the most suitable planting area of flue-cured tobacco,it is the main producing area of highquality flue-cured tobacco. The middle elevation is also the suitable planting area of flue-cured tobacco.[Conclusion] By using GIS technology,on the basis of realizing zoning index spatialization,the suitability zoning of flue-cured tobacco planting in Longxian was completed and the zoning map was made.
