Abstract

Abstract:

The industry of Anji white tea as the core agricultural industry is an important starting point for rural revitalization in Anji, Zhejiang. Establishment of tea planting regionalization in Anji County will provide favorable support for planters to build an ecological tea plantation in this area. Based on meteorological observation data such as temperature and relative humidity, basic geographic data and soil data from 6 national meteorological observation stations and 49 encrypted automatic meteorological stations in Anji County and its surrounding areas, nine factors of meteorology, topography and soil were selected to carry out the fine simulation of spatial distribution, and the AHP method was used to establish the evaluation model of tea cultivation suitability zoning. Then the comprehensive regionalization of tea planting suitability was completed. The results show that the most suitable area for tea planting in Anji County is 623.09 km², which is distributed in Meixi Town, Xilong Township, Dipu Street, Changshuo Street and other areas in the north and middle of Anji County. The suitable area for tea planting is 622.46 km², which is distributed in the north and middle of the county, such as Dipu Street, Xiaofeng Town, Zhangwu Town, the west of Hanggai Town, and the north of Tianhuangping town; The dimensions of unsuitable cultivation area is 441.43 km², which is mainly distributed in the south of the county, including Zhangcun Town, Baofu Town, Shangshu Town, south of Tianhuangping town and Shanchuan town. Through the regionalization of the suitability of tea cultivation in Anji County, this paper provides a reference for the selection of geographical location for Anji white tea planting, and provides ideas for the high-quality production of tea seedlings.

Key words: Anji white tea, tea plantation, spatial distribution model, suitability evaluation, geographic information system (GIS), regional planning, AHP method, Anji County
