Tea Cultivation Suitability Evaluation and Driving Force Analysis Based on AHP and Geodetector Results: A Case Study of Yingde in Guangdong, China

Tea is an economically important crop. Evaluating the suitability of tea can better optimize regional layout industry and provide a scientific basis for planting plans, which also conducive to sustainable development in long run. Driving force analysis be carried out understand main influencing factors growth. The purpose this study was evaluate area, determine prioritization support government’s planning decision making. This used Sentinel image data obtain current land use area. results show that accuracy plantation classification based on images reached 86%, total 92%. Then, we selected 14 factors, including climate, soil, terrain, human-related using analytic hierarchy process spatial technology cultivation area comprehensive potential distribution map cultivation. moderately suitable (36.81%) accounted largest proportion evaluation, followed by generally (31.40%), highly (16.91%), unsuitable (16.23%). Among these areas, line with at Yingde municipal level. Finally, analyze contribution each factor tea, were quantitatively evaluated Geodetector model. most affecting evaluation temperature (0.492), precipitation (0.367), slope (0.302), elevation (0.255). Natural influence cultivation, human relatively minor. provides yield policy formulation, site selection, adaptation measures.
