摘要: 根据枇杷生长情况、受害程度与年度极端最低气温、种植区域的坡向、坡度的关系,确定枇杷冻害等级指标;利用福建68个气象台站的地理信息资料,建立枇杷冻害指标的空间分布特征模型,通过GIS技术推算出50m×50m分辨率的冻害指标空间分布;利用GIS的空间分析能力,得出福建枇杷低温冻害的受灾分布规律。

Abstract: A study about scientific planting of loquat in Fujian province was conducted in order to reduce the frost disaster. First, indexes about the freezing grade of loquat were identified according to the relationships among loquat growth, damage degree, annual minimum temperature, and the aspect and slope of planting region. By using the geographical information data of 68 meteorological stations, spatial distribution model of freezing damage indexes of loquat was established, and the 50m×50m resolution spatial distributions were simulated by GIS. Therefore, distribution rules of loquat in Fujian province were analyzed by using GIS spatial analysis.
