摘要
阐明土壤盐碱化的灾害学概念提出的必要性,并分析土壤盐碱化传统概念在风险评价和其造成的灾害损失评价中的局限性。从深入剖析土壤盐碱化成因出发,以对区域内整体生态环境及社会经济造成损失为判别依据,提出了土壤盐碱化的灾害学定义并论述其概念的内涵与组成。通过与传统土壤盐碱化概念的比较和分析,进一步阐述新概念所具备的进步性和实际应用意义,最后建立了土壤盐碱灾害风险评价体系。
The necessity of the proposal of disaster science concept of soil salinization is clarified,and the limitations of the traditional concept of soil salinization in its risk and disaster loss assessment are analyzed.With the backdrop of in-depth analysis of the causes of soil salinity and the results of the overall ecological environment and socio-economic losses in the region,the disaster definition of soil salinization is introduced.The connotation and constituents of the concept are explained.Through comparison of the traditional and the new concepts,the advantages and practical significance are further demonstrated.This study has established a risk assessment system of soil salinity disaster.
