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.
