Research on the Spatio-Temporal Evolution of Water Resource System Resilience in the Yellow River Water Supply Area in Henan

Precipitation data from hydrological stations in the Yellow River water supply area of Henan Province were collected and organized. A fundamental database covering the period from 1990 to 2022 was established. The main types of data included meteorological, hydrological, and water supply records, as well as information on topography and underlying surfaces. Data on regional socioeconomic conditions and water network construction were also included. These data were obtained from the Henan Water Resources Bulletin, the Yellow River Conservancy Commission, and the Hydrological Yearbook of the Yellow River Basin. The data are shown in Table 1. Geographic Information System (GIS) technology was applied for spatial analysis, prediction, and decision support. The data were stored, analyzed, and managed using GIS. These processes supported the construction of a resilience indicator system for the water resources system.采集、整理了河南省黄河供水区水文站点的降水数据，并构建了覆盖1990—2022年的基础数据库。该数据库的核心数据类型涵盖气象、水文、供水记录，以及地形与下垫面信息，同时纳入区域社会经济状况与水网建设相关数据。本数据集的数据来源于《河南省水资源公报》、黄河水利委员会以及《黄河流域水文年鉴》，相关数据详见表1。研究运用地理信息系统（Geographic Information System, GIS）技术开展空间分析、预测及决策支持工作，并借助该系统完成数据的存储、分析与管理流程，上述工作为水资源系统韧性指标体系的构建提供了支撑。
