- 摘要:
- 根据黑龙江省水稻的生长发育期,以全省77个台站1961~2009年的逐日最低气温资料、霜冻历史灾情数据、社会经济资料、地理信息数据及作物生育期资料为基础,综合运用GIS空间分析和灾害风险评估数学方法,对水稻初霜冻致灾因子危险性、孕灾环境敏感性、承灾体易损性等多因子综合分析,构建水稻初霜冻灾害风险评价的框架、指标体系、方法与模型,绘制相应的风险区划图。结果表明:大兴安岭南部、黑河大部分地区、松嫩平原大部和三江平原西部个别地区为次高和高风险区,大兴安岭北部地区、牡丹江大部分地区、三江平原东部地区为次低和低风险区。
- Abstract:
- According to theory of crop growing stages,the rice first frost hazard risk,disaster environmental sensitivity,vulnerability of hazard-affected bodies were analyzed,the framework for disaster risk assessment was built as well as index system,method,mode and risk zoning map based on the daily minimum temperature data,frost historical disaster data,socio-economic data,GIS data and information on crop growth period of 77 meteorological stations nationwide in the period of 1961 to 2009.The result showed that south Daxinganling,Heihe,Songnen Plain and the western of Sanjiang Plain for the highest danger zone,north Daxinganling,Mudanjiang and the eastern of Sanjiang plain were the low risk zone.
