[目的]基于空间场景相似性的评价将烤烟(NicotianaglaucaL.)种植适宜区的土壤、坡度、交通、水利、日照以及社会经济等条件在地理信息中进行建模,构建烤烟种植的空间场景,通过与优良烤烟区的比较分析确定新的烤烟种植适宜区。[方法]选取云南省红河哈尼族彝族自治州的石屏县的龙朋镇和哨冲镇进行对比分析,共选取了30个自然条件因子,共分9类。[结果]9类因子及其权重排列顺序为ω土壤>ω日照>ω海拔>ω坡度>ω水利>ω交通>ω烘烤设施>ω历年种植、规划>ω其他,该地区种植烤烟的地理条件相似度为0.8943,说明两个地区的烤烟种植条件基本上是相似的。将非自然条件因素考虑进去,如把单位面积烟田的农户数量、单个农户的耕地数量、农户劳动力人口数、农户子女上学人数、农户的受教育程度、农户烤烟种植的积极性、当地烤烟辅导员的工作等因素考虑进去再进行分析,各因子权重排序为ω单位面积烟田的农户数量>ω单个农户的耕地数量>ω农户烤烟种植的积极性>ω农户的受教育程度>ω农户劳动力人口数>ω当地烤烟辅导员的工作>ω农户子女上学人数,该地区种植烤烟的地理条件的相似度为0.7031,说明影响该地区烤烟产量和品质的因素主要是非自然条件。[结论]基于空间场景相似性评价的烤烟种植适宜区分析,能够分析两个空间场景种植条件的相似性并对其作出评价,将有助于进一步了解影响烤烟生产的因素及其对烤烟生产所起的作用。
[Objective] Based on the evaluation of spatial scene similarity, the soil, slope, traffic, water conservancy, sunshine and socioeconomic conditions of Nicotiana aglauca L. planting suitable area were modeled in geographical information, and the spatial scene of planting tobacco was constructed. Comparative Analysis of Fine Flue - cured Tobacco Area and New Flue - cured Tobacco Planting Area. [Method] The comparative analysis was made between Longpeng Town and Senzhou Town, Shibin County, Honghe, Hani and Yi Autonomous Prefecture, Yunnan Province. A total of 30 natural condition factors were selected and divided into 9 categories. [Result] The order of 9 kinds of factors and their weights were: omega> soil> omega> omega> omega> omega> omega> omega> omega> o baking> o calendar planting, planning> ω other, The conditional similarity is 0.8943, which shows that the planting conditions of flue-cured tobacco in the two areas are basically similar. Taking non-natural factors into account, for example, the number of farmers per unit area of tobacco, the number of arable land per household, the number of rural laborers, the number of rural children, the education level of rural households, farmers planting flue-cured tobacco, local tobacco counselors And other factors into account and then analyzed, the weight of each factor ranked as ω per unit area of the number of households in the tobacco field> o the number of cultivated land per single household> ω the enthusiasm of farmers planting flue-cured tobacco> o the degree of education of farmers> > ω Work of Local Flue-Cured Tobacco Counselors> The similarity between the number of omega-rural children attending school and the geographical conditions of planting flue-cured tobacco in the region is 0.7031, indicating that the factors affecting the yield and quality of flue-cured tobacco in this area are mainly unnatural conditions. [Conclusion] The analysis of suitable planting area of flue-cured tobacco based on similarity evaluation of spatial scenes can analyze the similarity of planting conditions in two spatial scenes and evaluate them, which will help to further understand the factors that affect the production of flue-cured tobacco and their effects on the production of flue-cured tobacco Play a role.
