High precision topographic data on Lop Nor basin's Lake "Great Ear" ? and the timing of its becoming a dry salt lake

High precision elevation measurements using DGPS were carried out along three representative tran- sects for the "Great Ear" area, a dry salt lake within the Lop Nor basin. Results indicate that the Lop Nor basin is only 5.2 m deep and its lowest point occurs at the center of the "Great Ear". In addition, the basin is asymmetric - steeper in the southwest (0.19‰) and gentler in the northeast (0.09‰). Points along the same "Great Ear" ring were found to have an identical elevation value, but different when from different ones (lower towards the center). The spacing of the "Great Ear" rings was found to be closely related with the surface steepness. The closer the "Great Ear" rings are spaced, the steeper the ground surface, and vice versa. These findings support the argument that the "Great Ear" rings are the former shoreline trails left behind by Lop Nor water during the last few episodes of recession towards its total dry up. A comprehensive analysis of the high precision elevation data, historical accounts, aerial and satellite photographs and imagery, and official topographic maps of the study area suggests that the "Great Ear" area in the Lop Nor basin was incorrectly mapped as being covered by a great body of water on the 1963 topographic maps. A re-interpretation of the 1958 aerial photographs and newer remote sensing imagery indicated that the "Great Ear" ring structure was already in place in 1958 and it continued to appear on the subsequent remote sensing data without any major changes. It is estimated that lake water in the "Great Ear" area of the Lop Nor basin disappeared between the late 1930s and early 1940s.     

"太一"考

从史料学、民俗学、文字学等角度对“太一”进行考证 ,确认其出现乃原始母性崇拜的遗留 ,先秦诸子借用之作为解释万物起源的宇宙本原 ,秦汉时期受燕齐方士的鼓吹 ,才由万物之化育者变为万物之统治者 ,汉武帝始立为最高神。“太一”的原形“太乙” ,在齐鲁俗语中为媒神。东皇在古人观念中为伏羲 ,与之相配的“太一”为女娲 ,《九歌》实为迎高媒神女娲的一组祭歌。     

试述泰山碧霞元君演进的三个阶段

按照历史与逻辑相统一的方法，可将泰山碧霞元君的演化进程划分为三个阶段。最初，由曹操的名篇《气出唱》创造出泰山云霞仙境中的天仙玉女这一审芙意象，曹植、李白等诗人又不断加以描写、渲染，从而使泰山玉女在中固古代社会享有很高的知名度。然后，宋真宗为这位神女易玉像、砻石龛。引导泰山玉女从诗人的作品中走出，走进了香火缭绕的宫祠。最后。明宪宗修宫祠、赐颠名，其影响所度，使得明清时期的碧霞元君在京城及全国各地建庙，香火大盛，碧霞元君一名也沿用至今。与此同时，道士们一方面凭着斋醮科仪、住持焚修和承办庙套、营造节庆的狂欢气氛，对泰山玉女进行了卓有成效的炒作；另一方面凭着一片赤诚，兢兢业业，惨淡经营。博得了几代朝廷及地方官员对各种奉祭碧霞元君活动的赞赏和支持，这就使泰山碧霞元君成为中国道教的一大主神。     

杨庄煤矿塌陷湖水资源勘查计算

通过对塌陷湖的实地勘查,运用水均衡原理,计算出该湖可供开采的水资源,认为该塌陷湖可作为淮北市供水后备水源地之一。     

南四湖流域环境地质问题及其治理对策

南四湖流域的各种环境地质问题较突出，如水体污染、矿山环境地质灾害、地下水环境异常、南四湖淤积、地方病等。对流域环境地质问题的治理应综合考虑各种影响因素，建立完善的环境管理体制，增大环境治理投资比例，加强环境治理力度。     

Holocene lake deposits of Bosten Lake, southern Xinjiang, China

A 9.25-m-long sediment core from Bosten Lake,Xinjiang, provides detailed information about changes in the water budget and biological acticity over the last 8400 cal-endar years. The chronology is constructed from six AMS radiocarbon dates on the terrestrial plant remains. Based onanalyses of TOC, CO3, detrital compounds and biogenic SiO2,lake level fluctuations and periods of remarkably-negative water budget appeared at 8.4-8.2 cal ka, 7.38-7.25 cal ka,5.7-5.5 cal ka, 3.7-3.4 cal ka and 3.3-2.9 cal ka, respec-tively. As they are in-phase with low lake levels at Sumxl Co and Bangong Co in western Tibet Plateau and with paleo-lakes in Inner Mongolia, a climate-induced change to some-what drier and warmer conditions is inferred. A further drop in lake level after 1320 AD of about 200 yr duration may heattributed to a negative water balance prior to the main phase of the Little Ice Age. Deep and stable lake phases of 1500 yr and 1800 yr duration at 7.2-5.7 cal ka and 5.5-3.7cal ka coincide with maximum moisture during the Holocene Megathermai in China. The long term trend towards aridity since about 4.3 cal ka can dearly be recognised. The reduced water budget of Bosten Lake from 640-1200 AD may be attributed to local effects.

A method of quantitatively calculating amount of allochthonous organic carbon in lake sediments

Conclusion The lake sediments have registered the information of palaeoclimate and palaeoenvironment in the lake itself and the regional scale. This also leads to a complexity in study of the palaeolimnology by all kinds of proxies. How to purify these proxies to indicate the palaeoclimate has become a problem to be solved. Most of the proxies can qualitively identify the percentage of allochthonous and autochthonous organic components, e.g. δ¹³c_org CD/TC. The model introduced in this note has provided a method of quantitatively calculating the amount of allochthonous organic carbon. As for determination of regulating parameters, i.e. A1 and As, further work is still in need.     

应用主成份分析法评判湖泊营养类别

采用主成份分析法对１８个湖泊的是总磷、总氮、耗氧量、生物量、透明度进行了分析，并对湖泊营养类别进行了评判。分析结果表明，湖泊营养状态是总磷、总氮，耗氧量、生物量、透明度综合作用的结果，其中总磷的作用最大，其次是总氮。
