摘要
根据香蕉对生态气候条件的要求,分析确定了影响海南岛种植香蕉的气候区划指标。利用18个气象站点1961-2010年气候资料和DEM数据,采用GIS技术对无观测站地区500m×500m网格单元上的气候要素值进行了推算,并利用反距离权重差值法进行残差订正,制作香蕉种植气候区划专题图。该区划图划分出海南岛香蕉种植的最适宜、适宜、次适宜和不适宜区,针对各区域气候特点提出了相应建议,为香蕉合理布局及趋利避害、提高产量和品质提供科学依据。
According to the requirements of the banana on the ecological climate condition, climate regionalization indexes influencing Hainan banana planting were analyzed and determined. On the basis of 18 weather stations in 1961-2010 climate data and DEM data, the value of climate elements were calculated by GIS technology in 500 m 500 m grid cell and residual were corrected by inverse distance weight method to make a banana planting climatic regionalization thematic map. The zoning map is divided into optimum suitable time suitable and not suitable of banana planting in Hainan, and the corresponding suggestion for the regional climate characteristics were put forward to provide the banana reasonable layout theory and a scientific basis for improvin~ yield and aualitv.
