摘要
以500 m×500 m小网格插值为支撑,推导出湖南烟草生长阶段主要气候因子的小网格地域分布特征。参照我国烟草种植区域规划相关指标,立足于湖南烟草叶生长期中气候条件与自然灾害特点,历经业内专家测评后,拟定选用大田期降雨量及日照时长、成熟期降雨量及持续5 d气温最高值≥35℃热害共4个气候因子作为规划烟草种植区域的指标。以级别规划与GIS小网格技术手段为支撑,合理规划可栽植区。规划结果表明,湖南省多数地区的耕地适合栽种烟草,湖南省西部是最适宜的种植区。
Based on 500 m×500 m small grid interpolation,regional distribution characteristics of main climate factors in tobacco growing stage in Hunan were deduced.Based on characteristics of climate conditions and natural disasters during tobacco leaf growth period in Hunan province,and after evaluation of experts in industry,four climate factors,i.e.rainfall during field period,duration of sunshine,rainfall during mature period and maximum temperature≥35℃for 5 days,were proposed to be selected as indicators of tobacco planting area planning.Based on level planning and GIS small grid technology,planting area should be planned reasonably.Planning results showed that cultivated land in most areas of Hunan province was suitable for planting tobacco,and the western part of Hunan province was the most suitable planting area.
