天门市花椰菜种植的气候适宜性区划

基于模糊数学的隶属度函数,建立花椰菜(Brassica oleracea var.botrytis L.)气候适宜度模型,并据此将适宜区域分为不适宜、次适宜、适宜区。结合湖北省1∶250000 DEM高程数据,建立气候适宜度指数与经度、纬度、海拔的多元回归模型,基于普通克里金算法对模型残差插值建立湖北省1000 m×1000 m区划指标因子栅格数据。依据上述区划指标分级及打分标准,计算气候适宜性等级,通过叠加县级行政边界、裁剪、添加图例、比例尺等,制作出花椰菜种植布局精细化气候区划图。结果表明,天门市全境气象指标都是花椰菜生长的适宜区,针对可能影响花椰菜生长的灾害性天气,也作出了相应的气候分析。
