摘要
【目的】探明福鼎白茶的种植适宜区域,为福建省福鼎白茶的种植规划布局提供科学依据。【方法】应用福鼎白茶地理分布数据与气象资料(热量、光照和水分条件),采用MaxEnt模型研究影响福鼎白茶在福建分布的关键气象因子,并对其潜在分布进行适宜性区划。【结果】MaxEnt模型适用于福鼎白茶种植分布模拟,影响福鼎白茶种植分布的关键气象因子为3月平均气温、最冷月平均气温、≥10℃活动积温、多年平均极端最低气温和年降水量。福鼎白茶在福建的种植分布对生长关键期气温最敏感。福建适宜种植区域关键气象条件为3月平均气温低于15.0℃,最冷月平均气温10.7~11.9℃。福鼎白茶在福建的适宜区分布于24.76°~28.27°N、116.16°~120.45°E。【结论】福鼎白茶适宜及高适宜区域主要分布在宁德市各县(市)、南平市西部和中部、福州市东部和北部,约占全省面积的16.41%;次适宜区域主要分布在南平和三明市大部、福州市南部及莆田、泉州和龙岩市的北部地区,约占全省面积的46.00%。
【Objective】The suitable regions for planting Fuding white tea were explored,which provided scientific support for the layout for Fuding white tea planting in Fujian Province.【Method】Using the geographical distribution data of Fuding white tea and meteorological data(heat,light,and water conditions),the MaxEnt model was used to study the key meteorological factors affecting the distribution of Fuding white tea in Fujian.And the potential distribution of Fuding White tea was regionalized.【Result】The MaxEnt model was suitable for simulating the planting distribution of Fuding white tea.The key meteorological factors affecting the planting distribution of Fuding white tea were the average temperature in March,the average temperature in the coldest month,the accumulated active temperature≥10℃,the average extreme minimum temperature for years and the annual precipitation.The planting distribution of Fuding White tea in Fujian was most sensitive to the temperature during the critical growth period.The key meteorological conditions for suitable planting areas in Fujian Province were that the average temperature in March was lower than 15.0℃,and the average temperature in the coldest month was 10.7-11.9℃.The suitable distribution area for Fuding white tea in Fujian was within the range of 24.76°to 28.27°N and 116.16°to 120.45°E.【Conclusion】The suitable and high suitable areas of Fuding white tea are mainly distributed in the counties(cities)of Ningde,the west and middle of Nanping City and the east and north of Fuzhou,accounting for 16.41%of the provincial area;The sub-suitable areas are mainly distributed in Nanping and majority parts of Sanming City,the south of Fuzhou and the north of Putian,Quanzhou and Longyan City,accounting for 46.00%of the provincial area.
