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 fact that there is still some lack of critical research on the submerged flood diversion flood in the East of Honghu Lake, the study area also plays a very important role in ensuring the safety of Jingjiang Levee and Wuhan City. Therefore, in order to maximize the role of sub-flood, at the same time be able to minimize the loss. Through the use of GIS model and field investigation methods, this paper collects and organizes the related property data in the study area. First of all, this paper accurately calculates the flood loss rate under different conditions; then, using GIS technology to estimate the flood loss rate and flooding, respectively, and at the same time, formulates a model suitable for studying the flooding loss in the region; finally, Some of the specific risk management decisions and recommendations that apply to the region.
