Analysis of surface water resources in North three Counties of Langfang region
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.
