Research on Suitability Regionalization for Cangxi Actinidia Chinensis Introduction and Expansion in Sichuan Province

Cangxi county is taken as an example, using remote sensing and geographic information system (GIS) technology, combining the ecological and environmental factors suitable for the growth of Actinidia chinensis, analytic hierarchy process (AHP) and spatial analysis were used to analyze the topography, climate and soil. The suitability distribution of Actinidia chinensis was evaluated from four aspects of vegetation. According to different index factors, the map of suitable differentiation of Actinidia chinensis in Cangxi county was obtained, and the field test was carried out to verify it. The results showed that the total suitable area for introduction of Cangxi Actinidia chinensis was 115 800 km², accounting for 24.15% of the total area of Sichuan Province. Among them, the most suitable area is 6000 km², which accounts for 1.25% of the total area of Sichuan province, the more suitable area is 51 100 km², accounting for 10.65% of the total area of Sichuan province, and the suitable area is about 58 700 km², accounting for 12.25% of the total area of Sichuan province.
