洪湖东分块蓄洪区洪水风险管理政策研究

Flood Risk Management Policy East block Honghu flood diversion area

鉴于当前对于洪湖东分块分蓄洪区淹没损失计算仍然缺乏一些评判性研究,加之研究区域对于保障荆江大堤与武汉市的安全也发挥了非常重要的作用。所以,为了使分蓄洪作用发挥到极致,同时能够将损失降到最低。本文通过使用GIS模型,同时采取现场调查的方法,对研究区相关财产数据进行了收集整理。首先,本文准确地计算出了不同情况下的洪灾损失率;然后,使用GIS技术分别对洪灾损失率和淹盖领域进行了估量,同时制定了适合于研究区域洪灾淹没损失的模型;最后,提出了适用于该区域一些具体的风险管理决策和建议。

In view of the current block flood inundation loss Hong Hudong still lack some of the critical study and study areas for protection of Jingjiang River Dyke and Wuhan also played a very important role. So, in order to make flood diversion to new extremes, and to minimize losses. Article by using GIS models, along with field investigation methods, property related data were collected in the study area. First, the article accurately calculate flood loss rate under different conditions. Then, using GIS technologies on flood loss rate and measure the flooding covered areas, and develop suitable regional models of Flood inundation loss. Finally, apply some specific risk management decisions and recommendations in the region.
