摘要
在研究海南荔枝生产现状和生态适宜性基础上,密切结合海南荔枝生产实际,分析确定了海南妃子笑荔枝精细化农业气候区划指标。利用38个气象站点(包括20个区域气象站点)气候资料和DEM数据,采用GIS技术对无观测站地区30 m×30 m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,制作妃子笑荔枝种植气候区划专题图。该区划图划分出海南岛妃子笑荔枝种植的适宜、次适宜和不适宜区,针对各区域气候特点提出了相应建议,为妃子笑荔枝合理布局及趋利避害、提高产量和品质提供气象依据。
The current status and ecological suitability of Litchi‘Feizixiao’in Hainan were analyzed,based on which indexes for precise agricultural climate regional planning of Litchi‘Feizixiao’were selected.The climate data of 38 meteorological stations(including 20 regional meteorological stations)and DEM data in Hainan were used,and the values of climate elements in grid cells with a grid cell size of 30 m×30 m in the areas without data from the available meteorological stations were interpolated by using GIS.The residuals were corrected by the inverse distance weighting,and a Litchi‘Feizixiao’planting climatic regionalization thematic map was generated by using ArcGIS.The zoning map is divided into suitable area,sub-suitable area and unsuitable area for Litchi‘Feizixiao’planting in Hainan,based on which some suggestions on climate characteristics for each zone in Hainan were put forward to provide reasonable layout and scientific basis for improving yield and quality of Litchi‘Feizixiao’.
