摘要
通过对苍梧县各个镇低温冷害的分析,找出影响苍梧县砂糖桔生产的4个气候关键因子,通过归一化方法和加权综合评价法分析,利用地理信息系统(GIS)绘制出苍梧县砂糖桔低温冷害风险区划专题图。区划图明确分出苍梧县低温冷害的低风险区、次低风险区、中等风险区、次高风险区和高风险区。在此基础上,针对各风险区域进行了分析与评述,特别指出了防御低温冷害的措施,为苍梧县砂糖桔生产趋利避害和优化布局提供科学决策依据。
Based on analysis of cold damage in town of Cangwu County, 4 key climatic factors about the cold damage were screened out. The risk regionalization of cold damage of thematic map in Cangwu sugar orange by normalization method and weighted comprehensive evaluation method with the geographic information system （GIS） . The risk regionalization of cold damage second low risk area, medium risk areas, second high risk area the each risk area were analyzed and researched, And the cold could be divided into low risk area, high risk area clearly. On this basis, damage prevention measures were pointed out to provide scientific decision basis for optimum layout and avoid disadvantages for sugar orange production in Cangwu County.
