摘 要: | 在对烤烟与气候关系全面分析的基础上,采用楚雄州范围内10个气象站1981—2010年的气象统计资料、1:400万行政区地图和90 m分辨率的DEM高程地图,利用社会科学统计软件(SPSS)建立了烤烟适宜性评价气象因子与地理信息系统的空间模型,同时,结合前人研究经验和楚雄实际情况,确定出了楚雄烤烟适宜性种植区划指标,以3S(GIS、RS、GPS)技术为支撑,综合经度、纬度、海拔高度、坡度、坡向、降水、日照、气温等关键因子高精度的对楚雄州烤烟进行空间分析,得出了云南省楚雄州经度、纬度、海拔高度、坡度、坡向、降水、日照、气温等关键因子的空间分布情况,又按照楚雄烤烟适宜性种植区划指标对各关键因子进行等级划分,运用GIS的空间计算功能对楚雄州烤烟进行适宜性区划研究。结果表明:全州烤烟最适宜种植面积占全州总面积的60.74%,适宜种植烤烟面积占全州总面积的24.14%,次适宜种植面积占全州总面积的8.96%,不适宜种植面积占全州总面积的6.14%。确定出了楚雄州各县市烤烟适宜性种植的地理位置和不适宜种植地区,并分别对其原因进行了分析,为下一步烤烟科学种植、现代烤烟农业合理规划提供了参考,同时也为广大农业区划研究人员提供了一种新的高精度小网格的农业区划方法。

Abstract: | Based on comprehensive analysis in flue-cured tobacco relationship with climate,using the 10 meteorological stations statistical data from 1981 to 2010, To establish the Flue-cured tobacco suitability evaluation Meteorological factor and the space of the geographic information system mode,with 3 s (GIS, RS, GPS) technology as support,integrated The key factors such as longitude, latitude, altitude, gradient, slope direction, precipitation, sunshine, temperature and so on high precision for study on flue-cured tobacco suitability division in chuxiong, Results show that:the state of most suitable flue-cured tobacco planting area is 60.74% of the total area,the suitable for planting flue-cured tobacco area is 24.14% of the total area,the secondary suitable planting area accounts is 8.96% of the total area,the not suitable for planting area accounts is 6.14% of the total area,Identify the geographical position of suitable planting flue-cured tobacco or not,And its reason was analyzed,For the next planting flue-cured tobacco, reasonable planning of modern tobacco agriculture provide the reference,At the same time also for the majority of agricultural regionalization researchers provides a new method of high precision small grid of agricultural regionalization |
