摘要: 基于福建省1971—2018年冬季66个气象站点的逐日最低气温数据,采用层次分析法、熵权法、ArcGIS空间分析等方法,构建了福建省铁皮石斛寒冻害危险性区划指标,建立了基于地理信息的寒冻害危险性指数小网格空间推算模型,对福建省林下种植的铁皮石斛寒冻害危险性进行了区域划分。结果表明:福建省林下种植的铁皮石斛寒冻害轻度危险性区域主要分布在福建省东南沿海的低海拔地区,中度危险性区域主要分布在南平中部和南部、三明中部和东部、龙岩西南部和东部的中低海拔地区,重度以上危险性区域主要分布在南平北部、宁德西北部和龙岩中部等高海拔地区。通过实地验证,区划结果与实际较为吻合,研究结果可为福建省林下铁皮石斛的种植布局和防灾减灾提供决策参考。

Abstract: Based on the data of daily minimum temperature in winter from 1971 to 2018 from 66 meteorological stations in Fujian, we established hazard division index of cold and freezing damage to Dendrobium officinale and a small-grid spatial prediction model of hazard index to cold and freezing damage, based on geographic information using the AHP method, entropy weight method, and ArcGIS spatial analysis method. We further conducted a hazard zoning of cold and freezing damage to D. officinale planted in the understory in Fujian Province. The results showed that the mild hazard areas of cold and freezing damage to D. officinale were mainly distributed in the low altitude areas along the southeast coast of Fujian, and the moderate hazard areas were mainly distributed in the middle and low altitude areas along the central and southern Nanping, the central and eastern  Sanming, and the southwest and east of Longyan. The severe and above hazard areas were mainly distributed in the high altitude areas along the north of Nanping, the northwest of Ningde, and the central Longyan. The division results were well consistent with the actual situations in field verification. Our results could provide decision reference for the planting layout and disaster prevention and mitigation of D. officinale in Fujian Province.

Key words: Dendrobium officinale, cold and freezing damage, hazard division, GIS, Fujian Province.
