Refined Climatic Regionalization of Camellia oleifera in Anhui Province
Camellia oleifera is a unique woody edible oil species in China and developing plantations of woody oil species including Ca-mellia oleifera is an important way to increase edible vegetable oil output in China. Anhui, as one of the key provinces with Camellia oleifera plantations in China, has huge potential for developing the plantations further. In this paper, based on the climate and the spe-cies plantation data, an analysis was made on the current climatic suitability features for the species in Anhui using the Maximum entro-py model and ArcGIS. The results showed that the southern part of South Anhui is the most suitable area, the northern part of South An-hui is the suitable area, the areas along the Yangtze River and the southern part of Jianghuai Region are sub-suitable areas while the ar-eas to the north of the Huai River and the northern part of Jianghuai Region are unsuitable areas. In addition, with the meteorological data of 81 meteorological stations in the province from 1991 to 2020 and the species disaster index, a statistical survey was made on the frequencies of different grades of disasters in the suitable, sub-suitable and most suitable areas and a risk zoning map of different grades of disasters was developed. The expert scoring method was used to determine the weight coefficient of different grades of disas-ters to form the risk zoning map of drought and high temperature in the peak period of the fruiting stage, low temperature and cold dam-age and rain in the flowering stage. It is hoped that the results could provide scientific reference for optimizing Camellia oleifera indus-trial layout and technical support for straight-through meteorological service, improving the meteorological disaster risk prevention ca-pability and the plantation benefits.
