摘要: 水文勘测、环境监测和农业生产等领域的研究人员,需要将地理区域按气象因子划分为若干子区域,用于抽样和对比等后续分析研究。目前,基于气象因子的区域划分方法存在缺乏交互手段、输出形式和结果单一等问题。文中设计并实现了基于气象因子的气候区划可视分析系统,提供堆叠柱状图、雷达图、平行坐标系等视图,以及点选、悬浮等丰富的交互手段,允许专家通过聚类评估指标、气候地理分布、点簇关系以及自身领域知识来确定气候区划方案。同时,系统可展示气候区划的时序演化关系,验证代表站点与所属区域的属性匹配度,提高区划方案的解释性。最后,基于西南5省近50年的气象数据,通过探索区域划分方案、推演气候区划的时序变化等两个实际案例,验证了系统的有效性。
