Khanka Lowland

 

a low-lying plain in the southeastern USSR (Primor’e Krai, RSFSR) and northeastern China. The Khanka Lowland is bounded in the east by the Sikhote-Alin’ Range and in the north and west by the East Manchuria Mountains. In the south the Suifun Plateau opens onto the Suifun River valley. The valley is composed of Paleogenic and Neogenic sand and clay deposits covered with a thick stratum of gravel, pebbles, clays, and alluvial, lake, and lagoon sands. The lowland has a temperate monsoonal climate. Lake Khanka is located in the west, and flooding during summer monsoons and autumn typhoons is extensive. Forest-steppe and marshy meadows are typical of the landscape. The southern and eastern sections of the Khanka Lowland constitute the most densely populated region of the Soviet Far East. Agriculture, mainly rice growing, is highly developed. Extensive improvement work is being done.
