A Study on Flood Disaster Risk Vulnerability Assessment and Warning Monitoring System YuRong Yu, Hua Xiao and Wei-Chen Hao Abstract Flood disaster assessment system and warning monitoring are of great complexity, including a variety of uncertainties, such as stochastic, fuzzy, gray. In this paper, the risk vulnerability assessment and warning monitoring analysis have been introduced systematically and have been studied for characteristics of flood danger, vulnerability and flood control program optimization in flood fields. Flood disaster system is a multi-level, multi-index and complicated system with a lot of uncertainty. Risk vulnerability assessment is used for calculating the index subject in the paper. On the basis of analysis of the current Chinese flood disaster mitigation efforts in flood prevention research background and current situation analysis of the status quo, the paper points out the existing problems of current China flood control and disaster mitigation and the importance of flood control program optimization. Keywords Flood disaster • Risk vulnerability assessment • Warning monitoring system

21.1 Flood Disaster Risk Vulnerability Assessment System Analysis According to the theories of natural disasters risk analysis at home and abroad, and based on the system characteristics of flood disasters, we define the agricultural flood disasters vulnerability as: in a certain mode of agricultural production and socioeconomic background, specific regional agricultural system is sensitive to the properties of the flood threat, and it is effected jointly by natural environmental factors and agricultural socialeconomic factors. Agriculture flood disaster vulnerability analysis is divided into several steps: Step 1: qualitatively analyze the factors which affect the vulnerability of agricultural flood disasters; Step 2: establish the index system of quantitative evaluation of agricultural flood disasters vulnerability; Step 3: define the threshold and scoring criteria of the evaluation rating; Step 4: calculate the weight of the evaluation index; Step 5: use the weighted model to calculate the vulnerability of agricultural flood disasters in the relevant affected areas; Step 6: divide the vulnerability ranks of the agriculture floods in affected areas and use GIS technology to analyze the law of the geographic distribution of the vulnerability of China’s agricultural floods and on this basis, GIS technol
