摘要
在对武威市凉州区甜叶菊生长特性全面分析的基础上,采用研究区耕地质量评价整理的数字化图件和统计资料,在地理信息系统软件中叠加生成甜叶菊适宜性评价单元图,建立层次模型,计算得出适宜性分区。结果表明:确定出了凉州区行政区域甜叶菊适宜性区域和所占面积,其中高度适宜性种植面积、适宜种植面积、勉强适宜性种植面积、不适宜种植面积分别占耕地面积的47.89%、34.67%、9.77%和7.66%,并生成凉州区甜叶菊种植适宜性分区图。
Stevia planting suitability in Liangzhou district of Wuwei was evaluated by geographic information system software. Results showed that of the total arable land, highly suitable planting area accounts for 47.89%, suitable planting area account for 34.67%, barely suitability planting area account for 9.77% and unsuitable for planting area account for 7.66%. The map of Stevia planting suitability partition was made.
