Central Mountain Range

The Central Mountain Range is the principal spine of Taiwan, extending north–south and forming the island's topographic backbone. It contains the island's highest summits, hosts major watersheds that feed cities such as Taipei and Kaohsiung, and forms a climatic and ecological barrier influencing East Asian monsoon patterns and regional biodiversity. The range has been central to interactions among indigenous peoples such as the Amis people, colonial administrations like the Japanese rule in Taiwan (1895–1945), and modern institutions including the Executive Yuan planners.

Geography

The range runs roughly 305 km from near Keelung in the north to the vicinity of Hengchun in the south, separating the Taiwan Strait and western plains from the Pacific eastern coast near Taitung. Major massifs include the Yushan Range with Yu Shan, the Xueshan Range with Xueshan, and subsidiary groups adjacent to Dongyanshan and Qilai Mountains. Key passes and river sources such as the headwaters of the Love River (Kaohsiung) and Tamsui River arise on its flanks. Administratively the range touches multiple counties and cities, including Hualien County, Nantou County, Changhua County, and Taichung.

Geology

The range is the product of ongoing collision between the Eurasian Plate and the Philippine Sea Plate, a process responsible for uplift, folding, and faulting across Taiwan since the late Miocene. Lithology includes metamorphic complexes of slate, schist, and gneiss, intrusive bodies of granite linked to Cenozoic magmatism, and marine sedimentary sequences preserved in synclines. Notable tectonic structures include the Longitudinal Valley Fault and thrust systems associated with the Emei Shan-region deformation. Active seismicity from events such as the 1999 Jiji earthquake (also called the Chi-Chi earthquake) demonstrates ongoing crustal shortening, and geomorphic processes produce rapid rates of uplift and denudation observed by researchers from institutions like Academia Sinica and the National Taiwan University.

Ecology and Biodiversity

Altitudinal zonation yields diverse ecosystems from subtropical broadleaf forests to alpine shrub and grassland near the summits such as Yu Shan, supporting endemic taxa. Flora includes cloud forest species, endemic conifers, and orchids long studied by collectors associated with museums like the National Museum of Natural Science. Fauna features endemic mammals including the Formosan black bear, Formosan macaque, and endemic avifauna recorded by the Taiwan Bird Conservation Society. The range forms core habitat within protected areas such as Yushan National Park, Shei-Pa National Park, and Taroko National Park, and is a focus for conservation NGOs, research programs at National Taiwan University, and international collaborations on biodiversity hotspots designated under frameworks influenced by groups like the IUCN.

Climate and Hydrology

The Central Mountain Range intercepts moisture from the East Asian monsoon and Pacific typhoon tracks, producing orographic rainfall patterns that contrast western rain-shadowed plains with eastern windward slopes. Snowfall occurs seasonally on highest peaks such as Xueshan and Yu Shan, affecting alpine hydrology and summer meltwater regimes. Major rivers originating here, including tributaries of the Gaoping River and Zhuoshui River, supply irrigation for agricultural regions in Changhua County and municipal water to urban centers like Kaohsiung and Taichung. Watershed management involves agencies such as the Water Resources Agency (Taiwan) and intersects with infrastructure projects implemented by the Ministry of Transportation and Communications (Taiwan) and the Council of Agriculture (Taiwan).

Human History and Cultural Significance

Indigenous groups including the Bunun people, Atayal people, and Truku people have long cultural ties to mountain landscapes, with traditional hunting, ritual, and oral histories linked to particular peaks and valleys. Han Chinese migration during the Qing dynasty and settlement patterns altered lowland-frontier dynamics, while during Japanese rule in Taiwan (1895–1945) colonization, forestry, logging, and infrastructure such as mountain roads expanded. The range featured in nationalist-era development plans implemented by agencies like the Ministry of the Interior (Taiwan) and in postwar environmental debates involving organizations such as the Society of Wilderness. Cultural landmarks include mountain temples, indigenous sacred sites, and hiking trails promoted by groups like the Taiwan Alpine Club and celebrated in literature by writers associated with the Taiwanese literature movement.

Economy and Land Use

Land use varies from protected parks and watershed reserves to agriculture on mountain terraces producing highland tea, vegetables, and specialized crops marketed in Taichung and Taipei. Forestry operations during earlier decades provided timber to urbanizing centers, while contemporary economies emphasize ecotourism, mountaineering, and recreation managed by agencies such as the Tourism Administration (Taiwan). Infrastructure—roads, tunnels, hydroelectric facilities like those influencing the Mingtan Reservoir system, and small-scale irrigation networks—affect slope stability, sediment yield, and risk management coordinated with the Central Weather Administration (Taiwan). Mining and quarrying have been limited but have occurred historically in locations documented by the Government-General of Taiwan archives.
