摘 要:随着京津冀协同发展,廊坊市北三县经济社会快速发展,用水需求不断增加,水资源供需矛盾日益突出。通过matlab软件编程对北三县1956—2022年近67年降雨量和地表水资源量进行趋势性、周期性和突变性分析,发现降雨量和地表水资源量均呈现明显下降趋势,如果不考虑其他水源,当地水资源供需矛盾会日益突出。研究成果可为当地水资源的合理开发和优化配置提供技术支撑。With the coordinated development of Beijing-Tianjin-Hebei region,the social economy of North three Counties has developed rapidly,water demand has been increasing,and the contradiction between supply and demand of water resources has become increasingly prominent.This paper analyzes the trend,periodicity and mutability of rainfall and surface water resources in North three Counties in the past 67 years from 1956 to 2022 through matlab software programming.It is found that rainfall and surface water resources both show an obvious downward trend.If other water sources are not considered,the contradiction between supply and demand of local water resources will become increasingly prominent.This paper can provide technical support for the rational development and optimal allocation of local water resources.
关 键 词:北三县 降雨量 地表水资源量 趋势性 周期性 突变性
