摘要
以ALOS、RapidEye卫星数据为基础,结合ArcGIS和ERDAS软件,提取老挝琅南塔省现有耕地,并以现有耕地为基础,综合考虑海拔、坡度、坡向因素因子,采用统计方法,建立评价模型,进而采用空间分析、统计方法,得出老挝琅南塔省马铃薯种植适宜性评价等级分类。将马铃薯适宜性评价定为各耕地评价单元的土地适宜性,分为高度适宜(>70)、适宜(60～70)、基本适宜(50～60)、不适宜(<50)4个等级,并建立马铃薯种植区域适宜性评价等级矢量图。
To the basis of ALOS and RapidEye satellite data, combined with ArcGIS and ERDAS software, extracting the existing cultivated land in Laos, Luang Namtha Province. Based on the existing land of Laos, Luang Namtha Province, considering elevation, slope, aspect factors, the use of statistical methods to establish an evaluation model, and then using the spatial analysis, statistical methods, come to the evaluation grade of Laos, Luang Namtha Province potato suitable for planting map. Drawing a conclusion that Potato suitability evaluation affirms each evaluation unit＇s land suitability. It is divided into four grades： a high degree of suitability （ 〉 70）, suitable （ 60 - 70）, basic suitability （ 50 - 60）, inappropriate （ 〈 50）, and establish a suitable assessment level vector diagram of Potato planting area.
