Xiao Hinggan Range

▪ mountains, China
Chinese (Pinyin)  Xiao Xing'an Ling  or  (Wade-Giles romanization)  Hsiao Hsing-an Ling,  conventional  Lesser Khingan Range 

      mountain range in the northeastern section of Heilongjiang (Heilungkiang) province, northeastern China. The range has a northwest-southeast axis and is located to the southwest of the Amur River (Heilong Jiang). To the west it is connected to the Da Hinggan Range by the Yilehuli Mountains, which run northwest-southeast for some 375 miles (600 km). The southeastern end of the Xiao Hinggan Range is marked by the great fault line of the Sungari (Songhua) River (Sungari River) valley.

      Although the two ranges have similar names, the Xiao Hinggan is a completely different mountain system from the Da Hinggan (Da Hinggan Range) (Greater Khingan). The Da Hinggan Range is largely composed of rocks that are igneous (formed through the solidification of magma) and metamorphic (formed through a combination of pressure, heat, and water) and rose in the Jurassic Period (i.e., about 200 to 145 million years ago), whereas the Xiao Hinggan was until Quaternary times (the past 1.8 million years) a part of the great intermontane trough formed by the Northeast (Northeast Plain) (Manchurian) and Zeya-Bureya plains. The range was formed by the uplift of its relatively young sedimentary rocks in comparatively recent geologic times. The relief is generally rounded and gentle, the main sharp fault line running along the Amur River valley, giving the northeastern face a somewhat sharper contour than the southwestern one, which merges gently into the Sungari River plain. The range forms a watershed between the Amur River system and the Sungari and Nen (Nen River) system. The Xiao Hinggan is lower than the Da Hinggan and has elevations averaging between 1,650 and 3,300 feet (500 and 1,000 metres), with most of the range being below 2,000 feet (600 metres). The Xiao Hinggan's climate is slightly more temperate and much more humid. Winters, nevertheless, are still long and bitterly cold, and much of the area is under permafrost.

      The area is covered with timber, mostly consisting of larch and birch in the north and of mixed broad-leaved and coniferous forests (cedar, spruce, yew, birch, elm, and larch) in the south. Forestry is the main economic base, and in the southern part of the range a number of railways, centring on Nancha and Yichun, have been constructed to transport lumber.
