The results in these three regions have been given that (1) Ephedra, as dry and desert vegetation, the average percents are 7.7 in Yang Lake, 4.2 in Kunlun Rive, 7.5 in Doucuo Lake, and the datum in Yang Lake is higher than others;(2) Gramineae, as humid vegetation, the average percents are 1.2 in Yang Lake, 4.9 in Kunlun Rive, 12.0 in Kuhai Lake, increasing gradually from west to east;(3) Artemisia, as humid vegetation, the average percents are 22.2 in Yang Lake, 43.6 in Kunlun Rive, 48.8 in Kuhai Lake, increasing gradually from west to east, too;(4) Chenopodiaceae, as dry vegetation, the average percents are 52.1 in Yang Lake, 42.4 in Kunlun Rive, 11.5 in Kuhai Lake, however, decreasing gradually from west to east;(5) Artemisia/Chenopodiaceae ,the average data, as environmental changing index, are 0.45 in Yang Lake, 1.23 in Kuniun Rive, 5.59 in Kuhai Lake, increasing gradually from west to east, and there is higher data scope during 3.0~4.3 ka BP in these two lake sediment profiles, then decreasing;(6) Ephedra/Artemisia, data are all increased but the amplitude is different, such as 0.45 in Yang Lake, 0.34 in Kunlun Rive, 0.28 in Kuhai Lake, decreasing gradually from west to east.

代表气候湿润的禾本科花粉平均百分含量，三个地区分别为：1.2%、4.9%、12.0%，从西向东数值逐渐升高。③代表气候湿润的蒿属花粉平均百分含量，三个地区分别为：22.2%，43.6%，48.8%，从西向东数值逐渐升高。④代表气候干旱的草科花粉平均百分含量，三个地区分别为：52.1%，42.4%，11.5%，从西向东数值逐渐降低。⑤依据蒿属、藜科花粉百分含量，计算出环境变化指标，蒿属／藜科值，三个地区的平均值分别为：0.45，1.23，5.59，从西向东比值逐渐升高，⑥麻黄属／蒿属值，在全新世晚期，三个地区都呈上升趋势，但幅度存在差异，分别为：0.45，0.34，0.28，从西向东数值逐渐降低。

The Es formation was divided into seven third order sequences based on the seismic, drilling and logging data, and plans deposition system plane distribution maps of different time were plotted by dominance phase principle. The lower Es4 is flood-overlake facies mainly; the upper Es4 is meandering stream and braided river delta deposition above the shore shallow lake background; in the Es3 period, the south mainly developed braided river, meandering stream delta, the northeast area main developed meandering stream delta, the middle area mainly developed semi-deep lakean d deep lake sediments. From lower Es3 to upper Es3, the delta scale gradually increased and the depositional area gradually moved to the east and the southeast; the Es2 period was dominated by shore-shallow lake sediments and widely developed braided river delta and delta deposits; the Es1 period was dominated by shore-shallow lake shoal deposits, and in the south developed meandering stream and braided river delta deposits.The lothological traps of the Shahejie group are mainly fluxoturbidite and stratum lateral pinch-out, and its formation and the distribution of the lothological trap were controlled mainly by the basin structure characteristic, palaeogeomorphology and tectonic activity and so on. It had a beneficial geological condition to develope sublacustrine slump turbidite fans in Jishan, Jiangjiadian and Wawu.

利用地震、钻井、测井等资料，将古近系沙河街组划分出7个三级层序，通过剖面沉积学分析，以优势相原则绘制不同时期各亚段沉积体系平面分布图：沙四下总体以洪水-漫湖沉积为特征，沙四上沉积时期是在滨浅湖背景之上发育了曲流河三角洲和辫状河三角洲沉积；沙三段沉积时期南部主要发育辫状河、曲流河三角洲，西北部地区发育曲流河三角洲，中部地区主要为深湖—半深湖沉积；由沙三下至沙三上，西北部三角洲规模逐渐增大，沉积范围逐渐向东、东南方向推进；沙二段沉积时期为滨浅湖沉积，在背景之上广泛发育了辫状河三角洲和三角洲沉积；沙一段以滨浅湖滩坝沉积为特征，南部发育了曲流河三角洲和辫状河三角洲沉积；沉积地层中的岩性圈闭以滑塌浊积岩岩性圈闭和地层侧向尖灭型岩性圈闭为主，其形成和分布主要受盆地结构、沉积古地貌和构造活动强度等因素控制，北部基山、南部江家店和瓦屋具有发育滑塌浊积扇的良好地质条件。

Three main methods with lacustrine carbonates have been used to reconstruct the lake water palaeo-temperature at present. First, the technique of isotopic geological thermometer, since being put forward to reconstruct sea-water paleo-temperature, was subsequently introduced into lacustrine carbonate sediments for constructing lake-water based upon the function relationship between lake-water temperature and the oxygen isotopic compositions of lacustrine carbonate and lake-water. Second, paleo-temperature of the lake-water can be reconstructed by determining Mg/Ca values of the lacustrine ostracode shells. And third, paleo-temperature of the lake-water can be reconstructed based upon the statistic model between the oxygen isotopic composition of lacustrine carbonate and the Lake-water temperature by testing the modem hydrogeological parameters and some relevant isotopic data of the lake basin.

目前利用湖泊碳酸盐对湖泊古水温进行重建主要有三种方式，一是运用同位素地质温度计原理，利用水温与湖泊碳酸盐氧同位素值和湖水氧同位素值三者之间的函数关系，对湖泊古水温做定量研究；二是通过测定介壳[Mg(上标 2+)]/[Ca(上标 2+)]进而重建古水温；三是通过测定湖泊流域范围内现代水文气象参数及一些相关的同位素资料直接建立起湖泊自生碳酸盐氧同位素值与温度间的统计模型。
