广西双季早稻高温热害精细化风险评估与区划研究
Study on Fine-scale Risk Assessment and Regionalization of High Temperature and Heat Damage of Double-cropping Early Rice in Guangxi
摘要
Abstract
Based on disaster risk analysis principle,meteorological observational data from 1970 to 2020 from 89 national weather stations in Guangxi,the planting area and yield data of early rice in major production counties in Guangxi,as well as relevant geographic information data,the risk assessment indicators were screened from the aspects of the hazard of disaster-causing factors,vulnerability of disaster-affected bodies and disaster prevention and reduction capabilities.The disaster risk index method and analytic hierarchy process were used to construct a risk assessment model for the high-temperature damage risk of early rice in Guangxi.The GIS technology was employed to perform fine zoning analysis of high temperature heat risk for early rice in Guangxi.The results show that the areas of high comprehensive risk of high temperature and heat damage of early rice are mainly located near the left and right rivers valleys,the Guizhong basin,while low-risk areas are mainly distributed in the northwestern and northorn mountainous areas of Guangxi.The results of this study can provide reference for early rice production in Guangxi to seek advantages and avoid disadvantages,optimize the layout,and prevent and reduce disasters.关键词
