1 1. Regionalization theories and database 4. Natural disaster relief regionalization of China Section 2 The Natural Disaster Relief Regionalization of China 3. Urban natural disaster regionalization of China 2. Agricultural disaster regionalization of China

2 China (rural, urban) natural disaster regionalization map Regionalization map of China natural disaster relief Final Aim: Establish the national regionalization system for natural disaster aids The database of China natural disaster and aids GIS technique The database of social and economic eigenvalue of China China administrative region Theory 1 Disaster system theory Theory 2 Regional. theory Theory 2 Regional. theory Theory 3 Geographic information map theory Project Thoughts

3 1. Regionalization theories and database  Disaster systems theory D = A∩B∩C  Theory of territorial differentiation Zonality: latitude direction, ocean and land, altitude Non-zonality: geology, landform  Geographic information map theory Map+ chart: express the relation change 1.1 Regionalization theories

4 1.2 The principles of regionalization  Comprehension and main factor principle  Territorial conjugation principle  Integrality of county administrative boundaries principle  Quantitative and Tupu interaction principle  Dynamic, manipulation and practicability principle

5 Attribute data Space data China administrative region maps China natural disaster newspaper database China natural disaster formative factors database China natural disaster effects database China natural disaster reduction information database China urban social and economic database China social and economic database The database of China natural disaster and relief The database of China natural disaster and relief Feature code 1.3 The whole structure of the database

6 Database construction (systematic database) Regionalization index——derivate database Foundation——original database Disaster relief region Feature chart of disaster relief region Regionalization result ——systematic database Map

7 2. Natural disaster regionalization of China - Agricultural disaster regionalization of China 2.1 Regionalizaiton system indexes Hazard –formative environment Hazard –formative Factors Hazard-affected Bodies Stability of Hazard –formative environment Risk of Hazard –formative Factors Vulnerability of Hazard-affected Bodies Natural disaster effects Topography,relief, vegetation, soil,hydrography and climate Intensity,frequency, effected arrange and recur period Population,land use,capital density, preventing and defending disaster level Effected population, disastrous Population,death population,area affected, disastrous area,affected area of crop growth,collapsed buildings

8 自然灾害 “ 自下而上 ” 与 “ 自上而下 ” 系统 2.2 Method and approach of regionalization Natural disaster “bottom-up” and “up-bottom” systems Principle Method Classification Process Scale Regional differentia rule of hazard-formative environment Regional differentia rule of hazard-affected bodies and hazard-affected factors Regional differentia rule of hazard effects Regional differentia rule of hazard-affected bodies and hazard-affected factors Divide up-bottom Combine bottom-up Hazard region Hazard district Hazard zone Basic unit of regionalization Basic unit of disaster Whole country Province or region Town or village

9 hazard-formative environment hazard- affected bodies hazard- formative factors Administrative Division borderline Natural disaster effects database Natural disaster system complex map Authority disaster effects data Natural disaster type map Adjacency index and distance index of disaster type map Basic units of natural disaster regionalization Adjacency index and distance index of basic units Division strategy of disaster zones comprehensive regionalization plan of regional natural disaster Natural disaster district division (un-demarcation) Middle scale macroscopically differentiated law of natural disaster Disaster large region division (un-demarcation) Large scale macroscopically differentiated law of natural disaster ① Spatial overlapping ① Split ① Spatial matching ② Evaluate ③ Fragment collection ④ Calculate ⑤ Combine ⑥ Calculate ⑦ Combine Collect Name ⑩ Divide ⑨ Divide ⑧ Divide Combine from bottom to top Divide from top to botto m

10 2.3 Classification system of regionalization Classification First level Second level Third level Fourth level Fifth level System of natural regionalization System of natural disaster regionalization Natural region Natural district Natural zone Landscape type Land type Natural disaster region Natural disaster district Natural disaster zone Basic units of natural disaster regionalization Type of natural disasters

11 2.4 Comprehensive regionalization of agricultural natural disaster in China South China Sea Islands

12 3.1 Regionalization method and technique flow 3 Natural disaster regionalization of China ——Urban natural disaster regionalization China Urban natural disaster regionalization map Synthetic intensity Synthetic level Urbanization map Natural disaster map Prior knowledge Model

13 Comprehensive urbanization index 3.2 Regionalization assessment of comprehensive urbanization level Urbanization map Urbanization map

14 3.3 Disaster intensity sub-area of major cities Structural damage Earthquake Flood City Land slide and debris flow Typhoon Dust-storm

15 Regionalization of Urban Integrated Disaster Intensity Natural disaster map Natural disaster map

16 3.4 Regionalization map of urban natural disaster legend Third-level boundary Second-level boundary First-level boundary

17 3.5 Regionalization characteristics table of Chinese urban natural disaster Regional name Area County Regionalization characteristics table of Chinese urban natural disaster(based on county boundary, first level regionalization ) Population Agricultural population (ten thousand persons) Non-agricultural population (ten thousand persons) Number of cities Area of built –up area (km2) Urban population (ten thousand persons) Urban population density (person/km2) Synthetical ability of land traffic Urban index of lamplight Integrated urbanization level index Coastal urban disaster area Eastern urban disaster area Western urban disaster area Total Regionalization characteristics table of Chinese urban natural disaster(based on county boundary, first level regionalization ) Regional name Coastal urban disaster area Eastern urban disaster area Western urban disaster area Total Hazard intensity index of flood Hazard intensity index of earthquake Hazard intensity index of typhoon Hazard intensity index of debris flow and landslide Hazard intensity index of debris sand storm Urban disaster type(arranged by intensity) Flood Earthquake Typhoon Landslide Sand storm Earthquake Flood Integrated natural disaster intensity index Integrated index

18 4 China natural disaster aid regionalization Earthquake sub-area Drought sub-area Frost sub-area Flood sub-area Typhoon sub-area Snow damage sub-area 2 Emergency capability 2 Emergency capability 1 Disaster preparedness capability 1 Disaster preparedness capability 3Recovery capability 5 Natural disaster relief regionalization Agriculture disaster regionalization Urban disaster regionalization Mud slide sub-area Dust-storm sub-area What to help? How to help? Who help?
