| 摘 要： | 以广东省86个气象站点1992-2005年的气象数据为依据、利用数理统计方法对1992-2005年香蕉平均气象产量与同期气候条件进行相关分析,确定香蕉种植的气候适宜性区划指标。根据广东86个站点1970-2009年的气候资料及对应站点的经纬度、海拔高度、坡度和坡向等基础信息数据,应用多元线性回归确定区划指标空间分析模型,推算出1km×1km的气象要素分布图。依托GIS技术空间分析功能,根据综合评分标准进行香蕉种植气候适宜性区划,得出广东省气候上最适宜种植香蕉的土地面积占17%,适宜区占18%,次适宜区占25%,不适宜区占40%。研究结果可为广东香蕉种植的合理布局提供参考。

| Abstract: | The indexes of climatic division for banana planting were identified through the correlation analysis between the banana yields and the climatic factors from 1992 to 2005.On the basis of the climatic data from 1971 to 2000 and latitude,longitude,altitude,slope and aspect information of the corresponding site,the spatial analysis models of zoning factors were gotten by the multiple linear regression analysis.Then the raster distribution maps of each meteorological element with grid resolution of 1km×1km were worked out.By the function of spatial analysis of GIS,the banana planting climatic zoning map of Guangdong province was done based on the comprehensive standard.The most suitable region accounted for 17%,the suitable region accounted for 18%,the sub-suitable region accounted for 25% and the unsuitable region accounted for 40%.Finally,the district maps could be provided to the department of agriculture planting for helping them in district choosing to avoid the impact of disaster. |
