In order to get the more accurate data of atmospheric capacity about this type of area, such as Yueyang, this paper analyzed the characteristics of Yueyang meteorology, gathered the features of atmospheric pollution sources, worked out the main problems in environmental protection. In addition, we analyzed the rule of atmospheric transport and diffusion, and took the Frequency of lake and breeze to modify the data of atmospheric capacity of Yueyang, which was achieved by A-P index, and compares the modified data of atmospheric capacity with the data of atmospheric capacity achieved by multi-source. The results indicated that according to the fact of lake and breeze, taking the frequency of lake and breeze to modify the data of atmospheric capacity of the field with stable lake and breeze, which is achieved by A-P index, made the atmospheric capacity more accurate. Accordingly, the result could be more reliable if the modified data is taken to calculate the atmospheric capacity when we assess the impact on the environment of the field with stable lake and land breeze.

Influenced by tectonic movement, there were no sediments in the area from Oligocene to Miocene. Appearance of marlite in the Pliocene, especially in Yaqueling region, proved localized depositing environment forming, for which there had only few amount of terrigenous matters to supply. Sedimentary facies association of alluvial fan, fan delta and inland lake appeared at the early and middle stage of lower Pleistocene, and association of fan delta and inland lake appeared at the later stage of lower Pleistocene and the early stage of middle Pleistocene. Net-veined laterite appeared at the top of lacustrine deposit, which reflected pedogenesis taking place after the end of deposition. Such evolution history proves that there had no lager river system traversing this area before the early stage of middle Pleistocene.
对于江汉盆地西缘宜昌地区来说,其沉积及古地理演化表现为:早白垩世为受天阳坪断裂控制的内陆湖泊沉积环境,沉积中心在天阳坪断裂的北侧,此时几乎不存在来自黄陵地区的水系;晚白垩世同样为受断裂控制的内陆湖盆环境,但湖盆面积扩大、断裂活动减弱,且后期出现成化湖相沉积;第三纪早期盆地由断陷盆地转变为坳陷盆地,同时石膏的出现代表了局限咸化湖盆的存在;渐新世—中新世,受构造影响,缺失该时期的沉积;上新世时在鸦鹊岭一带出现的泥灰岩沉积反映了陆源物质供应不足的局限沉积环境的存在;早更新世早中期为冲积扇—扇三角洲—内陆湖泊沉积,早更新世晚期—中更新世早期为扇三角洲—湖相沉积,后期出现沉积结束以后的网纹红土化作用。

Bennett.That was my commission,and I set out to Africa intending tocomplete Livingstone's explorations,also to settlethe Nile problem,as to where the headwaters ofthe Nile were,as to whether Lake Victoria consist- ed of one lake,one body of water,or a number ofshallow lakes; to throw some light on Sir SamuelBaker's Albert Nyanza,and also to discover theoutlet of Lake Tanganyika,and then to find outwhat strange,mysterious river this was which hadlured Livingstone on to his death—whether it wasthe Nile,the Niger,or the Congo.
贝内特。那就是我的使命,我动身去非洲意欲完成利文斯通的探险任务,还要解开尼罗河之谜,弄清尼罗河的源头在哪里,维多利亚湖仅由一个湖泊、一个水体构成还是由若干浅湖组成;弄清塞缪尔·贝克爵士发现的阿伯特湖;还要找到坦噶尼喀湖的出口,然后找出那条诱使利文斯通走上死亡之路的奇怪、神秘的河流是尼罗河,尼日尔河,还是刚果河?

Some innovative results are listed below:1、According to the lithologic characters,lithofacies,genetic classification and the geomorphy,the Quaternary system is divided into piedmont-gully\'s and plain\'s. The piedmont-gully\'s Quaternary sediment,which is about 3~20 meters in thick,is in the western hills of the study area.The plain\'s Quaternary sediment is widely distributed in the study area,which is about 30~60meters thick and become thicker from southwest to northeast.2、The Quaternary sediments of plain can be divided into five sedimentary cycles.The Late Pleistocene series Quantan group,at the bottom of the Quaternary System,is constituted by a fluvial facies-river and lake facies sedimentary cycle. The Late Pleistocene series Jiashan group,at the middle of the Quaternary sediment, is constituted by two fluvial facies-neritic facies-river and lake facies sedimentary cycles.The Holocene series Binhai group,at the upper of the Quaternary sediment, is divided into three parts,the under layer and middle layer are constituted by two littoral facies-river and lake facies sedimentary cycles,the upper layer is constituted by paludal facies,which was deposited at the lower-lying land like West Lake, Jiangcun-Gu dang,Xianghu lake,and coastal-estuary facies in other area.3、Folding and fault activities were weak in Quaternary and the tectonic activity had little influence on the Quaternary sedimentation.The ancient landforms,the evolvement of the river system and transgression were the main elements which controlled the Quaternary sedimentation in Hangzhou.The ancient landforms formed the basis of the Quaternary sedimentation.The evolvement of the river system and transgression individually or jointly controlled the Quaternary sedimentation of this area.4、The alternation of the climate was the main reason for the evolvement of the river systems and transgression,and it\'s also the reason why the Quaternary system of Hangzhou has the special sedimentary structure which is called soft interbed with hard layers.
通过研究取得了以下成果:1、根据岩性、岩相、成因类型和地貌特点,将本区第四系划分为山麓沟谷区沉积和平原区沉积:山麓沟谷区第四系主要分布于西部丘陵地区,厚度较薄且变幅大,一般厚3~20m;平原区第四系广布分区,由南西向北东逐渐增厚,一般厚30~60m.2、平原区第四系自下而上大体由五个完整或不完整的沉积旋回构成:底部上更新统全塘组,由河流相—河湖相的沉积旋回构成;中部上更新统嘉善组,由河流相—浅海相—河湖相两个沉积旋回构成;上部全新统滨海组,其下中两段由滨海海湾相—河湖相的两个沉积旋回构成,上段由西湖、蒋村—古荡、湘湖等低洼处沉积的湖沼相和其他地区沉积的滨海河口相构成。3、第四纪以来,研究区内褶皱、断裂活动微弱,构造运动对第四系沉积的影响不大,古地形、古水系的发育、变迁和海侵是杭州市第四系沉积的主要控制因素:古地形构成了第四系沉积的基底,水系与海侵在其后的不同阶段或分别或联合的主导了区内的第四系沉积。4、水系的发育、变迁和海侵的共同原因是天气变化,正是由于第四纪以来"冷热交替"的天气特点形成了杭州市第四系"软硬互层"的特殊沉积结构。

Brought forward and reasoned the forming mechanism of Maowusu sandy land. Based on the analysis of the development of Holocene rivers and related loess and windsandy geomorphology, the paper put forward the forming mechanism of Maowusu sandy land as follows: while the climate became dry, the exterior channels extended backwardly and cut through the remained lake system of ancient Hetao lake. This resulted in the rapid discharge of underground water. The vegetation living on this water resource was destroyed completely. Then the sand began to form.
