基于GIS的百色澳洲坚果种植气候适宜性分析

Climate Suitability Analysis of Baise Macadamia Planting Based on GIS

收集统计百色12个地面气象台站1991—2020年气象观测资料及对应台站地理信息资料,运用多元回归方法建立气象要素空间模型,根据澳洲坚果生产特性,以年降水量、花期降水量、坐果期平均月最高温度、果实成长期月最高温度、冬季平均月最高温度及海拔高度6个影响澳洲坚果生长的关键气候因子、地形因子作为区划指标。利用ArcGis进行分析,得出百色市适宜种植澳洲坚果的区域分布,适宜和次适宜面积约为1.7万km~2,占全市面积49%,不适宜总面积约1.8万km~2,占全市面积51%。表明百色市适宜种植澳洲坚果土地可利用率高,种植发展空间潜力大,可大力发展澳洲坚果产业,助力乡村产业振兴。

The meteorological observation data from 1991 to 2020 from 12 surface meteorological stations in Baise City and the geographic information data of the corresponding stations were collected,and the spatial model of meteorological elements was established by using the multiple regression method.The six key climatic factors and topographic factors that affect the growth of macadamias,such as the average monthly maximum temperature during the fruit setting period,the monthly maximum temperature during the fruit growth period,the average monthly maximum temperature in winter and the altitude,were used as zoning indicators.Using ArcGis to analyze the distribution of suitable areas for macadamia planting in Baise City,the suitable and sub-suitable areas are 17,000 km~2,accounting for 49%of the city’s area,and the total unsuitable area is about 18,000 km~2,accounting for 51%of the city’s area.It shows that Baise City is suitable for macadamia planting with high land availability and great potential for planting development,which can vigorously develop the macadamia nut industry and help the revitalization of rural industries.
