摘要
为了优化气象观测站网布局,文章利用银川地区2016—2019年5—9月202个气象观测站日降水量、可用性和使用年限资料,基于信息熵理论,采用熵权法和TOPSIS法对雨量站点进行综合评价。结果表明:站点雨量重要性排名的权重最大,其次是使用年限;优化后站网平均降水量整体空间分布特征与优化前一致,且优选站点数量较原有站点数量减少约20%。站网综合评价结果为银川地区站点升级改造提供理论依据。
In order to optimize the network layout of meteorological observation stations,the daily precipitation,availability and service life data of 202 meteorological observation stations from May to September 2016 to 2019 in Yinchuan area was comprehensively evaluated by using the entropy weight method and TOPSIS method based on the information entropy theory.The results show that the importance ranking of rainfall has the largest weight,followed by the service life.The overall spatial distribution characteristics of average precipitation of the optimized station network are consistent with those before optimization,and the number of preferred stations is reduced by about 20%compared to the original stations.The comprehensive evaluation results of the station network can provide a theoretical basis for the upgrading and reconstruction of the stations in Yinchuan area.
