Modeling the Potential Distribution of <i>Machilus thunbergii</i> under the Climate Change Patterns in China

Abstract

The potential geographic distribution and favorable climatic conditions of Machilus thunbergii under current and future predicted climates in China are predicted based on MaxEnt model and ArcGIS software. The results show that the AUC values in different time periods and emission seniors are more than 0.9, which indicates the prediction is excellent. Precipitation of the coldest quarter, precipitation of the driest month, annual precipitation, mean diurnal range, and temperature annual range are the most important environmental factors affecting the distribution of Machilus thunbergii. At present, the suitable areas of Machilus thunbergii are mainly concentrated in the eastern subtropics of China, with a total area of 118.47 × 10 4 km 2. The medium-suitability area and the high-suitability area are concentrated in Wuyi Mountains, Luoxiao Mountains, Xuefeng Mountains, Nanling and east of Taiwan Mountains. With the change of climate, the suitable area increases, and the medium-suitability area and high-suitability area migrate and expand to the east, and the low-suitability area expands slightly to the west and north. So, the simulated distribution of Machilus thunbergii should be one of priorities, when instigating in-situ conservation. The research results can provide a theoretical reference for the popularization and planting of Machilus thunbergii.

“…The Japanese bay tree is one of the most important forest trees in Japan, Korea, and China. This plant is prevalent in coastal forest areas in Korea [1,2]. The bark and roots of this plant are using as a traditional medicine in continental regions, while the wood is used as mosquito repellent incense [26].…”

“…Machilus thunbergii Sieb. & Zucc., commonly known as the Japanese bay tree, is a member of the Laurel family (Lauraceae), a diverse and widespread group found throughout tropical and subtropical forest areas of the world, especially in southern Korea, Japan, the Bonin Islands, the Ryukyus, Taiwan, and the warm temperate zones of China and the Philippines [1][2][3]. It is a broad-leaved evergreen tree with the potential to grow 30 m tall.…”

“…Parts of M. thunbergii plants have been used as a traditional medicine to treat edema, abdominal pain, and abdominal distension in Korea, China, and Japan [4,5]. Due to the destruction of natural resources and the ecological environment, M. thunbergii has been listed as a key wild plant protected nationwide in China [1]. Although plant pathogens commonly cause diseases in this plant, few fungal pathogens have been reported for this plant in Japan, China, Korea, and Taiwan.…”

“…(Lauraceae) is an evergreen broad-leaved tree up to 20 m tall, and its bark is dark brown with gray markings. It grows mainly in broad-leaved forests below 800 m and is distributed in warm regions such as Korea, China, Japan, and Taiwan [ 10 , 11 ]. The bark of M. thunbergia has been used in folk medicine for the treatment of abdominal pain and distension, leg edema, and anti-inflammatory responses [ 10 , 12 ].…”
