广西靖西烟区烤烟种植生态适宜性分析
以广西靖西烟区作为研究区,基于2012年多站点气象数据、200个土壤样点的养分数据和DEM高程数据,结合当地生产条件,选取气象、土壤养分和地形三大类生态条件下的11个生态因子,利用主成分分析法、层次分析法、指数和法等进行权重计算和指数运算,对三类生态条件进行适宜性分析,在GIS环境下进行3个图层叠加和重分类,将靖西烟区划分为适宜、较适宜和不适宜3个级别。结果表明:有6个乡镇集中在适宜区,其中,大甲、胡润、武平3个乡镇的适宜区面积比例均在90%以上,新圩、新靖、同德3个乡镇的适宜区面积占比50%以上。壬庄、岳圩、化峒、地州、渠洋等5个乡镇集中在较适宜区,龙邦和禄峒2个乡镇大部分面积划分为不适宜区...

Summary: | 以广西靖西烟区作为研究区,基于2012年多站点气象数据、200个土壤样点的养分数据和DEM高程数据,结合当地生产条件,选取气象、土壤养分和地形三大类生态条件下的11个生态因子,利用主成分分析法、层次分析法、指数和法等进行权重计算和指数运算,对三类生态条件进行适宜性分析,在GIS环境下进行3个图层叠加和重分类,将靖西烟区划分为适宜、较适宜和不适宜3个级别。结果表明:有6个乡镇集中在适宜区,其中,大甲、胡润、武平3个乡镇的适宜区面积比例均在90%以上,新圩、新靖、同德3个乡镇的适宜区面积占比50%以上。壬庄、岳圩、化峒、地州、渠洋等5个乡镇集中在较适宜区,龙邦和禄峒2个乡镇大部分面积划分为不适宜区,各分区之间呈明显的带状过渡趋势。因此,在实际生产中建议龙邦和禄峒部分烟区向适宜区和较适宜区转移。 |

Guangxi Research Institute of Forestry Science, Nanning 530003, China; 3. Baise Tobacco Company of Guangxi, Baise 533000, China) According to the meteorological data from many stations, the nutrient data of 200 soil samples, and the DEM alti- tude data of Jingxi tobacco-growing area of Guangxi in the year 2012, combined with the local production conditions, we selected 11 factors from the aspects of meteorology, soil nutrition and landform to analyze the ecological suitability of planting flue-cured tobacco in Jingxi area by using principal component analysis, analytic hierarchy process, index sum method and geostatistics with GIS. The results showed that: six villages and towns were concentrated in the most suitable region, the suitable planting area of Dajia, Hurun and Wuping towns all accounted for over 90%, and that of Xinxu, Xinjing and Tongde towns accounted for more than 50%; five |
