Issyk-Kul (also Ysyk Köl, Issyk-Kol: (キルギス語:Ысык-Көл) (:ɯsɯqkœl); (ロシア語:Иссык-Куль)) is an endorheic lake in the northern Tian Shan mountains in eastern Kyrgyzstan. It is the tenth largest lake in the world by volume (though not in surface area), and the second largest saline lake after the Caspian Sea. Although it is surrounded by snow-capped peaks, it never freezes; hence its name, which means "hot lake" in the Kyrgyz language ( in Chinese texts). The lake is a Ramsar site of globally significant biodiversity (Ramsar Site RDB Code 2KG001) and forms part of the Issyk-Kul Biosphere Reserve. ==Geography== Issyk-Kul Lake is long, up to wide, and its area is . It is second largest mountain lake in the world behind Lake Titicaca in South America. It is at an altitude of , and reaches in depth.〔(International Lake Environment Committee Foundation )〕 About 118 rivers and streams flow into the lake; the largest are the Djyrgalan and Tyup. It is fed by springs, including many hot springs, and snow melt. The lake has no current outlet, but some hydrologists hypothesize〔V.V.Romanovsky, "Water level variations and water balance of Lake Issyk Kul", in Jean Klerkx, Beishen Imanackunov (2002), p.52〕 that, deep underground, lake water filters into the Chu River. The bottom of the lake contains the mineral monohydrocalcite: one of the few known lacustrine deposits. The lake's southern shore is dominated by the ruggedly beautiful Teskey Ala-Too Range of the Tian Shan mountains. The Kungey Alatau of the Tian Shan runs parallel to the north shore. The lake water's salinity is approx. 0.6%— compared to 3.5% salinity of typical seawater— and, although the lake level is still currently some 8 metres (26 ft) higher than in medieval times, its level now drops by approximately 5 cm per year due to water diversion.〔(Lake Issyk-Kul )〕 Administratively, the lake and the adjacent land are within Issyk-Kul Region of Kyrgyzstan. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Issyk Kul」の詳細全文を読む スポンサード リンク
