中国旱涝分布图（1470-1570年）

该数据集是在国家科技基础平台“地球系统科学数据共享网”项目的支持下，以中国气象科学研究院主编，全国32家单位协作完成的《中国近五百年旱涝分布图集》为数据源，经扫描人工数字化得到101的年的矢量图。数据集包括：（1）1470-1570年中国旱涝灾害分布图，每年一幅，共101幅。将有数据的区域划分为“旱”区，“涝”区，“正常”3级；（2）1470-1570年中国旱涝灾害分布点数据，每年一期，共101期，覆盖全国范围，含122个站点，其中西部地区早期资料有缺失,东部地区较为完整。并将有资料的站点分为1,2,3,4,5(即涝、偏涝、正常、偏旱、旱)5个等级。该数据为研究中国的旱涝情况、气候变化，分析、利用气候资源提供数据支持，也为政府部分提供决策参考。

This dataset is developed based on the *Atlas of Drought and Flood Distribution Maps in China over the Past 500 Years*, which was edited by the Chinese Academy of Meteorological Sciences and co-completed by 32 institutions across China, supported by the National Science and Technology Infrastructure Platform "Earth System Science Data Sharing Network". The original atlas was scanned and manually digitized to generate 101-year vector maps. The dataset includes two parts:
1. Annual distribution maps of drought and flood disasters in China from 1470 to 1570, with 1 map per year, totaling 101 maps. The data-covered regions are classified into three categories: drought-stricken areas, flood-stricken areas, and normal conditions.
2. Point distribution datasets of drought and flood disasters in China from 1470 to 1570, with 1 dataset per year, totaling 101 datasets covering the entire country and including 122 meteorological stations. The early data in western China is partially missing, while the data in eastern China is relatively complete. The available stations are divided into five grades: 1 (severe flood), 2 (moderate flood), 3 (normal), 4 (moderate drought), and 5 (severe drought).
This dataset provides data support for research on China's drought and flood conditions, climate change analysis and climate resource utilization, and also offers decision-making references for relevant government departments.

背景与挑战

背景概述

该数据集涵盖了1470年至1570年共101年的中国旱涝分布情况，基于权威的《中国近五百年旱涝分布图集》数字化而成，包括矢量图和点数据两种形式，覆盖全国122个站点，将旱涝等级划分为旱、涝、正常等多个级别。数据集的特点是时间序列完整，但西部地区早期资料有缺失，东部地区较为完整，主要用于研究中国的旱涝变化、气候资源分析，并为政府决策提供数据支持。
