基于GIS的阜平县北流河区域山杏生态适宜性区划研究

基于阜平县气象局提供的2014—2018年12个监测点的气象资料、DEM数据、土壤质地图等资料，以山杏作为研究对象，将经格网化处理的25 m×25 m大小的栅格作为评价单元，运用多元回归分析以及残差订正、GIS反距离权重插值、模糊综合评价等相关数学模型，构建山杏适宜性评价指标体系，对阜平北流河区域山杏的生态气候适宜性进行评价。结果表明：研究区适宜种植山杏区域有346.95 km²，占北流河区域面积的72.70%；次适宜种植山杏区域有123.81 km²，占北流河区域面积的25.95%；不适宜种植山杏的区域有6.447 km²，占北流河区域面积的1.35%。研究结果可为作物气候适宜性评价提供参考。

Ecological Suitability Regionalization of Armeniaca sibirica in Beiliuhe Region of Fuping County Based on GIS

This article uses the meteorological data, DEM data, and soil quality maps of 12 monitoring points provided by the Fuping County Meteorological Bureau from 2014 to 2018. Taking Armeniaca sibirica as the research object, using the gridded grid of 25 m × 25 m as the evaluation unit, using multiple regression analysis and incomplete difference correcting, inverse distance weighted interpolation in GIS, fuzzy comprehensive evaluation and other related methods mathematical models, construct a A. sibirica suitability evaluation index system, and evaluate the climatic suitability of A. sibirica in the Beiliuhe area of Fuping. The results show that the suitable area for planting A. sibirica in the study area is 346.95 km2, accounting for 72.70% of the area of Beiliuhe; sub-suitable area for planting A. sibirica is 123.81 km2, accounting for 25.95% of the area of Beiliuhe; the area not suitable for planting apricot is 6.447 km2, accounting for 1.35% of the area of Beiliuhe. This research can provide reference for the evaluation of the climate suitability of crops affected by the vertical zonality in a certain area.
