安固里淖全新世湖面变化及其环境意义

地貌证据和钻孔沉积特征分析表明，安固里淖全新世湖面变化分为４个时期：湖面快速上升时期（１００００～７３００ａＢＰ），高湖面时期（７３００～６２３０ａＢＰ），湖面快速下降时期（６２３０～５３００ａＢＰ），湖面波支动性下降时期（５３００ａＢＰ以来），其中高湖面达到现代湖面以上２８ｍ的位置，代表全新世气候最暖湿的时期。安固里淖全新世湖面变化及其反映的气候变化，与邻近地区具有良好的对应关系，其高湖面与中国

HOLOCENE WATER LEVEL CHANGES OF ANGULINAO LAKE AND THEIR ENVIRONMENTAL SIGNIFICANCE

By synthesbo gcornorphological and sedimentary data, the history of Holowater level changes at Angulinao is divided into four periods: (a) the period of rapid lake level rising (about 10000 ~ 7 300a BP), (b) the period of high lake level (about 7 300 - 6230aBP), (c) the period of rapid lake level dropping (about 6 230 -- 5 300a BP), (d) the period offluctuant lake level dropping (since 5 300 a BP). The high lake level of Angtilinao represents avery good sitUation of clhate and cochfor to the warmest and most hulind stage ofHoloare Megathennal in China. The begilming of the strong wind action at Angulinao keepsin step with the start of rapid foers ndbotation in mid-- Holocene. The high sea level alongChinese shore appeared around 6500- 4000a BP, which laal apparently behind the high lakelevel inland. This ~us that inland lake levels are more sensihve to correspond with clhatechanges.
