摘要:
基于广西1961~2013年冬季寒冻害过程最低气温资料、地理信息数据及地表反射率资料,采用统计学中的多元回归法,构建了基于地理信息与地表反射率相耦合的最低气温降尺度模型及区域250m×250m网格点逐年冬季寒冻害过程最低气温数据库。在此基础上,结合糖料蔗寒冻害等级指标,对广西区域糖料蔗寒冻害时空分布特征进行了分析,并编制了广西区域糖料蔗不同寒冻害等级频率图及糖料蔗寒冻害产量损失率图,同时对广西糖料蔗寒冻害风险等级进行划分及评述。这一结果对糖料蔗种植优化布局及政策性农业保险费率的确定有积极意义。
Abstract:
Based on the minimum temperature of chilly or freezing injury process from the winter of 1961 to 2013, the geographic information data and the surface reflectivity data of Guangxi, the reduced scale model of the minimum temperature based on integrating geographic information and the surface reflectivity and the database of area 250m×250m grid point of the minimum temperature of chilly or freezing injury process were set up by the multiple regression method of statistic. On the basis of these, the time-space distribution characteristics of sugar-cane chilly or freezing injury was analyzed by combining the sugarcane the chilly or freezing injury indexes and the different chilly or freezing injury grade frequency figure and chilly or frozen injury yield loss rate figure were drawn. The sugarcane chilly or freezing injury risk grade was divided into seven regions and each region was commended respectively. The results is helpful for the sugarcane planting optimization layout and determination of policy-oriented agricultural insurance rates.
