摘要
提出一种面向省域的冬小麦种植图斑提取技术和多维度多视角的综合统计分析方法,能够快速准确地提取大范围冬小麦种植图斑及其在行政区划、地形地貌、土地利用类型、基本农田、粮食产能区空间的分布特征,可为全省农作物种植优化布局、粮食估产与安全、土地开发利用、生态建设等提供空间决策支撑。
In this paper,we put forward a technique route mainly including the method of map spot extraction for winter wheat planting based on multi-source high resolution satellite images and aerial orthophoto images and a set of multidimensional comprehensive statistical analysis methods,which could quickly and accurately extract the planting areas as well as their spatial distribution characteristics in administrative divisions,landforms,land use types,basic farmland,and grain energy producing areas in the whole province.The research results can provide spatial decision-making for crop planting layout,grain yield assessment and food security,food production assessment and food security,land development and utilization,and ecological construction in the province.
