Trade along the Silk Routes reached its zenith during the Pax Mongolica, a period of relative stability in Eurasia that was created by the Mongol empire in the 13th and 14th centuries. It is generally believed that the Silk Routes declined after the disintegration of the Mongol empire in the second half of the 14th century and that they fell into disuse after the 1453 Ottoman conquest of Constantinople as the Europeans sought alternative maritime routes to Asia. This paper examines the aftermath of the Mongol-era overland and maritime Silk Routes from a non-Eurocentric perspective. Seen from the standpoint of various successors to the Mongol empire, such as the Timurid empire, the Mughal empire, the Uzbek khanate, the Ottoman empire, Manchu Qing, and Russia, the overland and maritime Silk Routes did not really collapse or sharply decline during the post-Mongol period. These Mongol successor states maintained close and thriving overland trade relations with each other or some important maritime trade relations with Southeast Asia. It may be argued that the Silk Routes in the post-Mongol world functioned rather independently of European seaborne commerce.

In order to find out the relationship between spring phytophenological index and temperature index for the past nine years (2010~2018), this study identified the relationship between temperature changes and trends in spring phytophenological index of sprouting, flowering and leaf unfolding of Pinus densiflora Siebold & Zucc., Larix kaempferi (Lamb.) Carrière, Quercus mongolica Fisch. ex Ledeb., Rhododendron mucronulatum Turcz., Lindera obtusiloba Blume and Acer pseudosieboldianum (Pax) Kom. in Daegu Arboretum, Palgong mt., Juwang mt. and Gaya mt. The change in temperature was caused by an increase in the monthly average temperature between March and April compared to February for nine years, and the average temperature of Daegu Arboretum and Palgong mt. were higher by region. The sprouting, flowering and leaf unfolding were the fastest of the Lindera obtusiloba and the slowest of the Pinus densiflora for each species, and the fastest plant season in Daegu arboretum came. SPI (Spring Phytophenological Index) tends to advance by -1.267~-6.151/9 years, with the largest Pinus densiflora (-6.151/9 years), with the lowest rate of change for Rhododendron mucronulatum (-1.267 days/9 years). Species which shows significant values in sprouting, flowering and leaf unfolding is Rhododendron mucronulatum and Pinus densiflora, which correlate with the mean temperature of January to March. As a result of checking the time series change of SPI, the change rate in the four regions was all negative and the phenolocal index was all accelerating. Among them, the rate of change was greater in inland areas such as Daegu arboretum, Palgong Mt. and Gaya mt. and the rate of change was slightly lower in the case of Juwang mt., which is somewhat distant.
