基于GIS的辽宁省大豆种植气候区划

Soybean Agricultural Climate Demarcation Using GIS Technique

为辽宁省大豆种植合理布局提供依据,利用1981—2015年辽宁省54个气象台站的气候资料、大豆产量及大豆生育期资料,根据大豆生长发育对气象条件的要求,确定气候区划指标,采用GIS技术对大豆各区划指标进行网格推算并予以空间分析,进而将全省大豆种植划分为适宜种植区、次适宜种植区和不适宜种植区3个区域。通过分区评述和分析,提出辽宁省发展大豆种植的合理建议。

To provide the basis for rational distribution of soybean planting in Liaoning Province,the authors confirmed the climatic regionalization indicators according to the demands of soybean growth and development for climatic conditions by using climatological data of 54 meteorological stations,soybean yield and growth period in Liaoning Province from 1981 to 2015.And GIS technique was employed to conduct grid calculation and spatial analysis,and the soybean planting area was divided into three regions,including suitable planting area,sub-suitable planting area and unsuitable planting area.At last rational suggestions were proposed for soybean planting in Liaoning Province according to subregion assessment and analysis.
