Abstract: Qianshan City of Anhui Province is one of the key tea-producing counties and cities in China, and tea is an important economic crop in the city. The land suitability evaluation of tea planting can give full play to the advantage of natural resources and provide a basis for adjusting and optimizing tea distribution and production in Qianshan. Nine factors affected by the conditions of soil, topography and geology were selected as influencing factors of tea planting in Qianshan, and a hierarchical structure model was set up and the weight of each factor was determined to evaluate the tea plantation land suitability. The results show that the highly suitable area for tea planting in Qianshan covers an area of 370.10 km², accounting for 26.00% of the study area, and the moderately suitable area covers 423.97 km², accounting for 29.79% of the total. The highly suitable areas were mainly distributed in Guanzhuang Town, Tafan Village and Chashui Town. Moderate suitable areas were mainly distributed in Chashui Town, Wumiao Village, Shuihou Town, Longtan Village. The high quality and high-yield tea plantation in Qianshan were mainly located at the highly and moderately land suitable areas for tea planting.
