根据新疆西部艾比湖195个样品的孢粉资料和岩性变化，重建了∼13870年来的湖泊水文变化和全流域植被变化。结果表明，直到∼13,870年代，∼13,870年代才出现湖泊或沼泽环境，在盆地水分条件改善的情况下，∼13,870-7430年代盆地的凹陷以沼泽或湿地环境为主。在∼7430至∼3620BP之间，经历了凹陷的湖泊海侵和盆地内植被的改善。从∼3620BP开始，湿度条件不断改善，导致进一步的湖泊海侵和进一步的全流域植被改善。∼1400年至∼1150aBP的干旱时段中断了∼3600年以来的晚全新世湿润时期。我们的新疆地区综合(区域平均)湿度指数表明，新疆地区中、晚全新世以逐渐湿润的气候为主。新疆地区的这种湿润趋势被认为与北欧的冬季变暖和冬季湿润趋势有关。全新世中晚期冬季日照强度的逐渐增加可能增强了北大西洋的蒸发，为西风带系统注入了更多的水汽，从而为包括新疆在内的下风区带来了更多的降水。
This research focuses on the reconstructions of the lake hydrologic variations and the basin-wide vegetation changes over past ∼13,870 years based on pollen data of 195 samples and the lithologic variations obtained from Lake Aibi in the western part of Xinjiang area. Our results showed that lake or swamp environment did not come into existence until ∼13,870 cal. BP and swamp or wetland environment dominated the depression of the basin between ∼13,870 and ∼7430 cal. BP under ameliorated basin-wide moisture conditions. The following period between ∼7430 and ∼3620 cal. BP witnessed lake transgression in the depression and vegetation amelioration within the basin. The moisture conditions were continuously ameliorated from ∼3620 cal. BP onward, leading to further lake transgression and further basin-wide vegetation amelioration. A dry interval from ∼1400 to ∼1150 cal. BP interrupted the late Holocene wet epoch of the past ∼3600 years.Our synthesized (regionally-averaged) moisture index of Xinjiang area indicates that a gradual wetting climate dominated the mid- to late-Holocene in Xinjiang area. This wetting trend in Xinjiang area is hypothesized to have been associated with the winter warming and winter wetting trends in northern Europe. The gradual increase of winter insolation in mid- to late-Holocene might have enhanced evaporation in the North Atlantic Ocean and injected more moisture to the westerlies system, therefore bringing more precipitation to the downwind area including Xinjiang.
