河南省暴雨灾害泄洪区分布数据集（2021年）

本数据内容包括河南省暴雨灾害泄洪区分布数据集（2021年）。暴雨灾害：一次短时的或连续的强降水过程，在地势低洼、地形闭塞的地区，雨水不能迅速宣泄造成农田积水和 土壤水分过度饱和给农业带来灾害；甚至于引起山洪暴发、江河泛滥、堤坝决口给人民和国家造成 重大经济损失。泄洪区：泄洪区是指在河流湖泊水位上升，达到洪水警报线时，由人工打开一缺口，向规定的地区引流洪水，减少对水域周边的危害—这一地区就被称为“泄洪区”。

This dataset includes the Distribution Dataset of Flood Diversion Areas During the 2021 Henan Rainstorm Disaster.

Rainstorm disaster: A short-term or continuous heavy precipitation event. In low-lying, topographically enclosed regions, rainwater cannot drain quickly, resulting in farmland waterlogging and excessive soil moisture saturation, which causes disasters to agricultural production. It may even trigger mountain torrents, river floods, and dam breaches, inflicting major economic losses on the people and the nation.

Flood diversion area: A flood diversion area refers to a designated region where artificial breaches are opened to divert floodwaters when the water level of rivers or lakes rises to the flood warning level, so as to mitigate harm to the surrounding areas of the water body; this region is called a "flood diversion area".
