苍梧县砂糖桔种植气候区划

Climatic Regionalization of Citrus shatangju Planting in Cangwu County

为了给苍梧县砂糖桔生产提供趋利避害和优化布局的科学决策依据。对苍梧县砂糖桔生产的气象条件进行分析,找出影响低温冷害的4个气候关键因子,采用国家基础地理信息中心提供的1:5万广西基础地理背景数据,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,提出了防御低温冷害的相应对策。

Based on the analysis of meteorological conditions for sugar orange production in Cangwu county, 4 key climatic factors that affects the chilling damages were screened out the low-temperature chilling injury risk zoning thematic map was maken by normalization method and the weighted comprehensive evaluation method and adoption of 1：5 Wan Guangxi foundation geographical background data offered by national fundamental geographic information center and geographic information system （GIS） . Zoning map clearly distinguish meaning county chilling damages of low risk area, second-low risk area, medium risk area, higher risk area and the high risk area. On this basis, each risk area were analyzed and evaluated, and the corresponding countermeasure of defense chilling damages was put forward.
