摘　　要：光照、气温、土壤类型、降水量、土壤含水量、海拔、坡度、重金属污染等自然生态环境对烤烟的分布、生长发育及品质有重要影响,同时也是烤烟种植优化配置必不可少的基础信息。基于空间技术的烤烟种植生态环境综合评价分析的目的就是应用遥感、地理信息等空间技术,实现烤烟种植区域生态环境信息的三维立体采集及烤烟种植生态环境适宜性空间分布信息评价。主要研究内容是分析影响烤烟种植及品质的生态因子,应用ARCGIS空间分析功能获得海拔、坡度因子,应用常规的遥感模型反演植被指数、地表温度、土壤含水量和太阳辐射因子,应用Kriging插值加密地球化学数据建立烤烟种植生态环境综合评价指标体系。通过基于空间技术的烤烟种植生态环境适宜性等级空间分布优化分析结果与实验区烤烟种植示范基地和烤烟种植区域的调整结果进行对比,可知该方法是有效的。Aims Our objective is to provide a scientific basis for optimization of tobacco planting. Methods First, we analyzed the ecological factors that impact tobacco＇s cultivation and quality. Second, we applied ARCGIS spatial analysis to obtain elevation and slope factors. Third, we obtained the vegetation index, surface temperature, soil moisture and solar radiation factor based on conventional remote sensing models. Fourth, we used Kriging interpolation to encrypt the geochemical data. Then we applied AHP analysis to establish a comprehensive evaluation system for tobacco cultivation. Important findings Several environmental factors have a major impact on tobacco distribution, growth and quality. These include light, temperature, soil type, rainfall, soil moisture, altitude, slope and heavy metal pollution. These factors are also essential for optimizing allocation of tobacco cultivation. The spatial distribution of tobacco cultivation in the experimental area needs to be optimized.
