摘要:

山洪灾害调查评价是1949年来水利行业最大的非工程措施项目,是规模最大的全国性防灾减灾基础信息普查工程,历时4年,涉及全国30个省305个市2138个防治县(区),国土面积755万km2,人口近9亿。运用普查、详查、外业测量、分析计算等多种手段,掌握了中国山洪灾害防治区范围、人员分布、下垫面条件、社会经济、历史山洪灾害等基本情况,科学分析了山丘区小流域的暴雨洪水特性,评价了现状防洪能力,计算了预警指标,划定了危险区,为山洪灾害预警预报和应急救援决策提供了基础信息支撑。本文系统介绍了全国山洪灾害调查评价的核心要点,综述了调查评价成果,归纳了调查评价成果要素类型,揭示了全国山洪灾害防治区、人口、历史山洪灾害事件与预警能力的空间分布一致性,即山洪灾害各要素集中分布于青藏高原-四川盆地过渡带、川滇交界地区、黄土高原区、东部沿海地区及华北等地区,最后初步探讨了该成果的应用前景。全国山洪灾害调查评价成果将为中国山洪灾害监测预警预报体系建设及防灾减灾能力提升提供丰富的基础数据支撑。

Abstract:

National Flash Flood Disasters Investigation and Evaluation project is the largest non-engineering projects in water conservancy industry since the establishment of new China in 1949. It is also the largest scale of general census on disasters background in flood management and mitigation fields. The whole project lasted for 4 years, covering 30 provinces, 305 cities and 2138 counties, with a total land area of 7.55 million km2 and a population of nearly 900 million. Through general census, on-site investigation, field measurement, hydrological analysis and calculation, and comprehensive evaluation methods, the spatial distribution, human settlement, underground situations, impacts, social and economic situations, hazard zoning, warning indicators and historical situations of flash flood disasters were collected. The storm flood characters in mountainous areas were also analyzed. The flood control ability of selected villages were assessed and the critical rainfall index of these villages were obtained. The hazard zones were finally identified, all of which provided a strong information support for flash flood early-warning and forecast and residential safety transfer. We systematically introduced the key focuses on the investigation and evaluation project of national flash flood disasters, made a general review on the collection of data and information, summarized thousands of investigation results and elements during this huge project. We also discussed the spatial pattern of these elements. Based on these survey data, the characteristics of flash flood disaster prevention areas, the human settlement features and spatial pattern of storm flood were further analyzed. Finally, flash flood prevention areas, population distribution, flash flood warning ability and historical flash flood disaster events were discussed. It was found that the national flash flood prevention areas, human settlement, historical flash flood events and warning ability appeared to be spatially consistent. They were mainly distributed along the transitional zone of Qinghai-Tibet plateau and Sichuan basin, the borders of Sichuan and Yunnan provinces, the Loess plateau zones, the Eastern coastal areas and the North China areas. Meanwhile, future application and analysis on diversified utilization of investigation and evaluation results of national flash flood disasters were proposed, providing a solid data foundation for flash flood monitoring and warning system, disaster management and mitigation researches, a better platform of technological promotions, in both flood management departments and other relevant fields.
