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。
The natural ecological environment such as light, temperature, soil type, precipitation, soil moisture content, elevation, slope and heavy metal pollution have an important influence on the distribution, growth and quality of flue-cured tobacco and are also the basic information necessary for the optimal allocation of flue-cured tobacco planting. The purpose of the comprehensive evaluation and analysis of flue-cured tobacco planting ecological environment based on space technology is to use the remote sensing, geographic information and other spatial technologies to achieve the three-dimensional collection of ecological environment information in flue-cured tobacco planting area and evaluate the spatial distribution information of flue-cured tobacco planting ecological environment. The main research content is to analyze the ecological factors affecting the planting and quality of flue-cured tobacco. The altitude and slope factors are obtained by using the spatial analysis function of ARCGIS. The vegetation index, surface temperature, soil moisture content and solar radiation factor are retrieved by conventional remote sensing model. Kriging interpolation encryption Geochemical data to establish flue - cured tobacco planting ecological environment comprehensive evaluation index system. The results of spatial distribution optimization of flue-cured tobacco planting ecological environment adaptability level based on space technology are compared with the adjustment results of flue-cured tobacco planting demonstration base and experimental area flue-cured tobacco planting area. The results show that this method is effective.
