Evaluation And Management Of Social Vulnerability Of Agricultural Natural Disasters

The special topography and geomorphology in China is the biggest risk of agricultural natural disasters in the world.Because of the unreasonable development of the climate change and the agricultural resources,the risk of agricultural natural disaster loss is increased.The increasing risk of agricultural natural disasters has seriously affected the sustainable development of agriculture.Therefore,strengthening the risk management of agricultural natural disasters has become an increasingly urgent theoretical and practical problems.The theory innovation of natural disaster social vulnerability management began in 1960 s opened a new perspective and a new method of disaster risk management.A large number of theory and practice of disaster show that natural disasters are not only "natural",more and more as "society".From the perspective of social vulnerability,more and more attention has been paid to risk management.Compared with other fields,the research on social vulnerability of agricultural natural disasters is more lag.Although the agricultural insurance and other social tools to represent the beginning of the use,but the overall system of agricultural natural disaster social vulnerability theory and methods are just in the initial stage.Under this background,this paper will focus on the evaluation and management of the social vulnerability of agricultural natural disaster risk.In order to effectively complete the agricultural natural disaster social vulnerability management,relative researches have the following problems: first,vulnerability ?social vulnerability?risk of agricultural natural disasters belong to different areas of research.How to effectively explore the related theories,and then makes the integration of agricultural natural disaster social vulnerability management subject with strong continuity and the innovation in the academic? Second,the content and management of agricultural natural disaster social vulnerability get some characteristics,mechanism and evaluation method still needs further effective mining,in addition,the problem of how to reflect the social vulnerability of agricultural natural disaster risk research from the perspective of the advantage;third,how to explore a set of agricultural natural disasters in our society measure theory model,index system and the measurement method of vulnerability,on this basis,the corresponding policy recommendations on the basis of what should be.First,The Main Content of The Thesis:First,it defines the connotation and extension of agricultural natural disaster and social vulnerability,and studies the mechanism of agricultural natural disaster risk caused by social vulnerability.The basic connotation of agricultural natural disaster social vulnerability force mechanism and three-dimensional disaster subsystem extension on the basis of social vulnerability research paradigm from the perspective of factors,agricultural subsystem social dimension related corresponding coping styles,etc.to force mechanism of agricultural natural disaster risk disaster mechanism of deconstruction.It emphasizes that the mechanism of agricultural natural disaster risk disaster is not caused by purely natural factors,but the corresponding social dimensions of influencing factors play a huge role,and further excavation.Second is to construct the evaluation method and index system of agricultural natural disaster social vulnerability.The key to evaluate the social vulnerability of agricultural natural disasters and their influencing factors lies in the establishment of corresponding theoretical models,the selection of measurement methods and the selection of indicators.This paper draws on the existing social vulnerability assessment and management theory,constructs the evaluation model and the force mechanism of the corresponding three-dimensional carrier system,on the basis of factor analysis,entropy method and unconditional regression is divided into a number of other methods of quantitative analysis,force mechanism and system under the guidance of this phase should be looking for a proxy the effective measure of agricultural natural disaster social vulnerability,and make an evaluation about the relevant influence factors.Third is to design the path and mechanism of the management of social vulnerability to agricultural natural disasters,and to show the application of social vulnerability in social risk management.Emphasize the "government" and "market","farmer" is the agricultural natural disaster risk social vulnerability management of the three main body,improve the main behavior way and mutual cooperation is conducive to enhancing the management function of agricultural natural disaster social vulnerability.Among them,it is the most important way to improve the overall management level of agricultural natural disasters and social fragility by guiding the market rationally and forming effective cooperation with the government.Second,The Main Findings of The Thesis:Firstly,agricultural natural disasters and social vulnerability management are effective means to improve the risk response of agricultural natural disasters.The connotation of the social vulnerability of agricultural natural disasters mainly emphasizes the comprehensive response ability of social dimensions of disasters.It mainly reflects the resistance,resilience and Resilience Based on the theory of disaster cycle management.The extension of social vulnerability to agricultural natural disasters mainly emphasizes the three dimensional disaster carrying subsystem,which is mainly agricultural,agricultural and agricultural industries.Agricultural social vulnerability of natural disaster disaster mechanism emphasizes the disaster response and control system for agriculture itself with all factors to the social dimension of the show,in order to reduce the influence caused by disasters or expand the overall risk of loss.Based on the perspective of social vulnerability,it is helpful to improve the comprehensive understanding of the theory of agricultural natural disaster risk and disaster,and the corresponding management is also an effective complement and supplement to the existing market and government disaster behavior.Secondly,social vulnerability of agricultural natural disasters,showed a downward trend in general,and there were obvious differences in different regions.Studies have shown that agriculture and its related subsystems,natural disasters and social vulnerability all exhibit the fine characteristics of long-term downward trend,that is,the ability of agricultural and related subsystems to cope with natural disasters is increasing year by year.Through further empirical research on the area that have obvious regional differences in social ability to cope with natural disasters of Agriculture: the overall agricultural natural disaster social vulnerability level,Eastern and central regions,better than the central region better than the western region;moreover the time trend,agricultural natural disaster social vulnerability management to enhance the level of the eastern region is higher than the speed the central region,while the central region is higher than the western region.Thirdly,the social vulnerability of agricultural natural disaster influence factor has the heterogeneous characteristic.Based on the agricultural natural disaster vulnerability factors related to social vulnerability has homogeneity of empirical research on the influencing factors that also showed different characteristics: the effective means of helping agricultural natural disaster vulnerable social groups at the time of the disaster is more inclined to the government to improve their ability to respond to disasters,and social vulnerability the lower group is more dependent on the market and education to improve their ability to respond to disasters;in addition,with the effective involvement of the market and the government income of non-agricultural employment and education to enhance the level of agricultural industry,will promote the natural disaster awareness,so as to improve their ability to respond to disasters.Fourth,the key to the management of social vulnerability to agricultural natural disasters is the establishment of a government guided market mechanism.The government is agricultural natural disaster social vulnerability management is the most important subject of act,the government can use agricultural natural disaster risk control system,science and technology,provide the effective supply of funds and other means to improve the effectiveness of market of agricultural natural disaster risk coping intervention.Third,The Main Innovation of the StudyFirst,the study of the social vulnerability of the risk management of agricultural natural disaster is introduced,and the agricultural risk management measures are enriched and developed.Agriculture is the combination of natural reproduction and social reproduction.The formation and management of agricultural natural disaster risk must also be combined with the natural and social dimensions.Disasters are not only natural,but also social.But for a long time,the academic research and policy making are more inclined to the natural factors and characteristics of agricultural disasters,and the corresponding social vulnerability research has been seriously neglected.The vulnerability this study focuses on the natural disasters of agriculture society,especially agricultural disaster mechanism in-depth study from the perspective of social vulnerability,the innovation of research perspective of agricultural disaster risk management,and provides a new research idea of theory innovation of agricultural risk management and related research.Second is the agricultural natural disaster social vulnerability analysis and evaluation system research,constructed the micro foundation of the social vulnerability of agricultural natural disasters.Although the study on the vulnerability of the society has aroused extensive attention in other disciplines,and has been continuously applied and promoted in the field of agriculture.But,in general,the theoretical research of social vulnerability is still in the exploratory stage,especially the quantitative evaluation of the research is seriously lagging behind.The related research in the field of agricultural natural disaster social vulnerability is in the initial stage.This paper in reference to a large number of social vulnerable basic literature research,combined with the agricultural natural disaster risk management and related theoretical characteristics,builds up the relevant sub agricultural natural disaster social vulnerability dimension system,It designs the corresponding social vulnerability evaluation index system,and conducts an empirical study using the related data,and the vulnerability of agricultural disaster risk of the dynamic evaluation for agricultural natural disasters and social good foundation for further study on the vulnerability of the lay,provide an effective basis for formulating agricultural risk vulnerability management policy.Third is the analysis of the factors affecting the social vulnerability of agricultural natural disasters,which provides an effective research method and path for the management of the vulnerability of agricultural natural disaster risk.Based on the agricultural natural disaster social vulnerability discovery,An Empirical Study of the factors affecting the related factors affecting vulnerability has homogeneity,also showed different characteristics,provide an effective basis for formulating agricultural risk vulnerability management policy.
