摘要
城市化过程中可能会占用大量的农田和耕地,及时准确地获取我国水稻种植区域高质量和高精度的信息以及结合相关区域的空间数据进行空间分析对当地各类农业发展具有重要的意义。文章以云南省曲靖市马龙区为研究区域,以2015年5月的Landsat 8卫星影像作为分类影像,分类得出马龙区的水稻主要分布于研究区域北部和东北部的平坦区域;在坡度分级中水稻种植区主要分布于缓坡区。
In the process of urbanization, a large amount of farmland and cultivated land may be occupied. It is ofgreat significance for local agricultural development to timely and accurately obtain high-quality and high-precisioninformation of rice planting areas in China and to conduct spatial analysis combined with spatial data of relevant areas.In this paper, Malong District, Qujing City, Yunnan Province is taken as the research area, and Landsat 8 satelliteimages in May 2015 are taken as classification images. It is shown that:(1)the rice in Malong District is mainlydistributed in flat areas in the north and northeast of the study area;(2)in slope grading, rice planting areas are mainlydistributed in gentle slope areas.
