Recent study of lithology and sedimentary characters of the 3 rd member of Shahejie Formation of the Lower Tertiary in Dongpu Depression, has revealed many evidences indicating shallow water sedimentation and evaporation sequence, which could be used to interprete. The origin of the halite and gypsum interlayered in black colored mud located in the basin center. We is believe that the black colored mud is formed during high-level stage and that the halite and gypsum are deposited during low-level stage caused by evaporation. The paleowater depth is estimated from the data such as the character of sediments distribution, the species and diversity of Ostracode. According to the calculation and estimation, the maximum depth of lake water is 30 m. In addition, some evidences indicating frequently fluctuating of the lake level during the sedimentation of the 3 rd member of Shahejie Formatoin have been found, which are: (1) the frequent alternation of black colored mud and gypsum and halite; (2) 'rubble-made sand' in the sandstone, which indicates that the sand deposited during the highstand time was eroded into sand rubble and was transported, deposited with sand during the lowstand time; (3) In the sandstone interbeded with black mud of deep water environment, sandstong with cross bedding that was deposited in shallow water environment and current flow was found. The data of lithology, well log and seismic reflection character and the estimated paleowater depth were used to study the lake level fluctuation during the sedimentation of 3 rd member of Shaheje Formation. It is believed that in Dongpu Depression, during the sedimentation of 3 rd member of Shaheje Formatoin, the lake 1evel fluctuated frequently with large scale cycle and small scale cycle. According to the data of well log, response of resistivity and core, cycles of 6 scales were recognized, and the frequency of 6 th scale cycle is 1000/Ma. The minimum extent of lake level fluctuation is calculated according to the thickness of single halite bed or single gypsum bed. Combined with the palaeotopography character, the prossess of large transference of lakeshore line in landscape orientation has been explained. Basied on this study, a dynamic sedimentary modle was eastablished. As revealed in this modle, delta and bech sandbody were deposited along the shoreline and black mud with thin layer carbonate rock was deposited in the deposition center during the highstand time. During the lowstand time, the sandbody previously deposited along the shoreline was eroded and was prograded toward the sedimentation center of the basin, and during the weathering time, salt and gypsum rock was deposited in the center of deposition of the basin.

东濮凹陷沙三段沉积时期 ,湖平面变化频繁 ,有长周期 ,也有短周期 ,根据录井及岩芯等资料识别出的湖平面变化的 6级周期 ,其变化频率约为 10 0 0次 /Ma。根据计算 ,东濮凹陷沙三段沉积时期湖水最大深度为 30m。在高位期 ,盆地沉积中心发育暗色泥岩夹薄层碳酸盐岩 ;在水位下降期 ,边缘相砂体不断向盆地中心进积 ;在低水位期 ,盆地沉积中心发育盐膏岩沉积 ,因此在垂向上常发育深水相暗色泥岩与砂岩频繁互层 ,以及深水相暗色泥岩与盐膏岩频繁互层 .这种砂体多为低水位期三角洲成因 ,是东濮凹陷很重要的含油气储层

Qinghai Lake is the largest one of inland lakes in China. Some issues about water level drop, lake area shrinking and lake separateies have brought to broad attentions in recent years. Remote sensing researches for these issues were discussed in this paper. Landsat MSS, TM, ETM+ images and Chinese FY-1C, FY-1D, HY-1A satellitic data from 1975 to 2002 were applied to this study. Furthermore, we collected some useful data including relief map, water depth map and hydrological data. Those satellitic data, combined...

Qinghai Lake is the largest one of inland lakes in China. Some issues about water level drop, lake area shrinking and lake separateies have brought to broad attentions in recent years. Remote sensing researches for these issues were discussed in this paper. Landsat MSS, TM, ETM+ images and Chinese FY-1C, FY-1D, HY-1A satellitic data from 1975 to 2002 were applied to this study. Furthermore, we collected some useful data including relief map, water depth map and hydrological data. Those satellitic data, combined with useful data, were processed and analyzed, some results revealed that the lakeshore physiognomy have greatly changed from 1975 to 2000. The region changed mostly located in the west shore near the Bird Island and Buha River, in the north shoreShaliu River and the east shoreSha Island and Haiyan Bay. Due to rich land-carriage materials from Buha River and lake currents action, the west shore of lake is progressing towards lake. The famous Bird Island and Haisepi Island become the part of land; Also, the east shore was accumulated eroded by the removal of sand dune. Shadao Lake and Haiyanwan Lake were gradually separated from Qinghai Lake. On basis of lakeshore line change, we estimated that lake water level dropped about 2 m from 1975 to 2000, by the approach to matching two images and contrasting water depth data. This numeric value estimated was close to hydrological observation value 1.71 m. Also, this study estimated that the area of Qinghai Lake was 4405.64 km2 in 1975, and was 4256.04 km2 in 2000. FY-1D image on June, 2002 and field investigating results revealed that Haiyanwan Lake with an area or 100 km2 has been separated from Qinghai Lake. Water level drop and lake variation were the main cause of lake shrinking. In addition, we carried through field investigating and lake water depth measuring in the south-easters lakeshore of Qinghai Lake in Sep., 2002. The study indicated that the relativity of the grey scale of TM1 band image and water depth was very high in this lake. As a result, the water depth retrieval model was established.

青海湖是我国最大的内陆水体,它及其流域的生态环境近来一直倍受广泛关注. 其水位下降、湖水面积缩小、湖体分离等更是研究的热点问题. 本文针对这些问题展开遥感调查与研究,收集了多时相、多种信息源的影像数据;分析了1975年至2000年25年以来湖泊的变迁及成因,湖岸变化及湖体分离状况;用遥感方法反推25年以来湖水位的变化;计算了1975、2000年两个年份的湖水面积,并遥感分析了湖水面积萎缩的原因. 此外,对青海湖进行了实地调查与水深测量,建立了该湖泊水深反演模型.

In the prehistoric time,there was a large uniform terminal lake named Zhuyeze in the lower reaches of Shiyang River.Along with the climate change and human activities,Zhuyeze began become separated and dry gradually.Lots of small lakes vestiges were left behind in this area.Among them,Baijianhu Lake is the largest.This article take TM image as the data source,after image enhancement,a group of alternate-color stripes which exist on the north bank of Baijianhu Lake were highlighted.After interpretation,analyses and investigation,8 of them were confirmed as the once lakeshore lines.Using(1∶50 000)DEM,the modern altitudes of these lines were obtained and the corresponding areas were calculated in GIS environment.The results show that the highest elevation of Baijianhu Lake was once(1 320 m) with the area 1 600 km~2.After that,Baijianhu Lake began shrink until dried completely in last century.

史前时期,在石羊河下游存在着一个面积广大的统一终端湖——猪野泽,随着气候的变化和人类活动的加剧,猪野泽逐渐分裂、瓦解并最后完全干涸,遗留下众多的终端湖残迹,白碱湖为其中规模最大、干涸最晚者。以TM遥感影像为数据源,通过影像增强,突出了白碱湖北岸岸坡上呈水平平行状分布的一组色调相间变化的条带。经过判读、对比分析和在GPS导航下的实地考察,其中的8条被确认为曾经的湖岸线。利用该地区1∶5万DEM,读取这些湖岸线现代条件下的高程,并在G IS中对各湖岸线相应的湖面面积和水量进行了计算。结果表明,白碱湖湖面的最高高程约1 320 m,相应的最大湖面面积为1 600 km2,其后经历过多次规模不等的退缩,直至上个世纪完全干涸。
