摘要
参考中国烟草种植区划指标,结合湖南烟叶生长期内的气候资源及气象灾害指标,通过专家评分指标,选取大田期降水量、大田期日照时数、成熟期降水量及成熟期连续5 d日最高气温高于35℃高温热害机率等4个指标组合作为湖南烟草种植区划指标.利用等级划分法和GIS技术,对湖南省烟草进行了适宜性区划.运用湖南土地资源信息,将土地资源信息与气候区划进行叠加,分析某一区域实际可利用的种植区域.结果表明,利用上述指标研究的区划结果与实际情况基本吻合,洞庭湖区为不适宜区,其他大部分地区耕地均可种植烟叶,怀化的中南部及邵阳的西南部是烟叶发展的重点区域.
With tobacco index discussed in this paper, the climate resource index and meteorology disaster index were referred, namely the precipitation of field stage, the hour of sunlight of field stage, the precipitation of mature stage and above 35 ℃ in the continue five days. The authors discussed the tobacco plant region in Hunan, the climate resource, the climate disaster index, with grade dividing standard and GIS technology practised. At the same time, the soil resource information will be considered to superpose the soil resource and the climate region result, the suitable region to be analysed. The result showed that: the research result will coincide with the fact; the Dongting Lake isn't suitable for planting tobacco. But the other region will be suitable to plant tobacco, furthermore, the tobacco plant main distribute the centre south of Huaihua and the south west of Shaoyang.
