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。

The area of Nantong in Jiangsu Province is a fluvial plain by Yangtze River. To the north of the mouth of river to the sea is a beach plain, which was once the boundless ocean in history, through the development of history, form the wide seabeach finally. The two plains, which are in the different location, have the different ways to utilize the soil. The Yangtze Fluvial Plain, whose soil is fertile, grew to be the well-known area of producing cotton, with people outnumbering the farmland, while the beach plain became a famous salt field. With the development of the coastline, Huainan saltern declined day by day and at the beginning of 20th century, under the advocate of local government and the call of modern industrialist, Mr. Zhang Jian, the salt field in the North of Jiangsu province underwent a great reclaim-plain movement, which brought a tide of spontaneous immigration to the area. During the movement, the key problem is the contest for the ground. As the ownership of the land of salt fields is complex, the unification of the ownerhship of land was not easy. Zhang creatively took advantage of the form of modern joint-stock company to solve the problem.

江苏省长江口北岸现南通地区为长江冲积平原，沿江口向北为海岸淤涨地区，历史上这里曾是汪洋大海，经过多年历史演变，终于形成广阔的海滩，两个不同的淤涨地区，对土地的利用截然不同，沿江地区土地肥沃，逐渐成为著名的棉产地，人多地少；沿海则成为我国历史上著名的两淮盐产地，随着海岸线的演变，淮南盐场日益没落，20世纪初，在政府的提倡和近代实业家张謇的发动号召下，苏北盐垦地区发起了一场波澜壮阔的垦殖运动，与此相适应的则是一场自发的移民大潮，在这两大潮流中，最核心的是对地权的争夺，由于两淮盐场地权复杂，统一地权实属不易，张謇等人创造性地运用近代股份公司的形式解决了这一难题。
