In application, the first coarse seismic facies classification effectively identified the channel, erevasse-splay, natural levee, alluvial flat and other subfacies etc, and the second fine reclassification aimed to the classified channel further identified the lateral bar, mid-channel bar, main channel sand body and other microfacies of a fluvial channel.

通过实际应用指出，初次的相对较粗的地震相分类研究可以有效地区分出了河道、决口扇、天然堤、河漫滩等沉积亚相，而针对刻画出的河道的再次地震相分类研究则可以有效地区分出了边滩、心滩和主河道砂体等沉积微相，并初步证实了地震相再分类研究在客观刻画地质体细节方面的优势。

Using maximum flooding surface and local explosure erosion surface as the correlation framework surface in the 4-th hierarchical base-level cycles, sand-body in the 3-th hierarchical base-level cycles formed in the 4-th hierarchical base-level cycles may be correlated layer by layer. The law of the sand-body and the characters of reservoir heterogeneity formed in the 4-th hierarchical base-level cycles are discussed. The study shows:①During early period of the 4-th hierarchical base-level cycle rising, subaqueous distributary channel formed, continuously stacked vertically, and migrated in limit range laterally, and channel sand-body stretches farther longitudinally, and lacks interbeds of mud rock and siltsand in sand rock, reservoir heterogeneity is relatively weak.②During mid-period of the 4-th hierarchical base-level cycle rising, subsaqueous distributary channel migrated actively, channel divided and converged strongly to form netted sand-body and sand sheet mainly, but interbeds of mud rock and siltsand increases gradually in sand-body, reservoir heterogeneity increased.③During later period of the 4-th hierarchical base-level rising and early period of the 4-th hierarchical base-level falling, reservoir sand-body was poor, and only form thin sand-body of subsaqueous distributary channel, subsaqeuous creveas and distal mouth bar, sand-bodys are surrounded by mud and silt rock.

进一步采用以第4层次基准面旋回中相当最大湖泛面的相转换面和具有区域性暴露侵蚀作用的层序边界面为等时地层对比框架的边界，对发育于MSC2—MSC4三个第4层次基准面旋回的第3层次基准面旋回内砂体进行了逐层等时对比，探讨第4层次等时地层对比格架内储集砂体发育分布规律，及储集砂体的非均质性特点，研究发现：①第4层次基准面上升初期发育的水下分流河道，砂体呈连续叠置、侧向迁移受限，纵向上呈长距离延伸的带状产出，砂体间泥、粉砂岩夹层少，储层非均质性相对较弱；②在第4层次基准面上升中期发育的水下分流河道侧向迁移活跃，纵向延伸过程中分流汇合作用强烈，以形成网状或席状连片砂体为主，但砂体间泥、粉砂岩夹层逐渐增多，储层非均质性增强；③第4层次基准面上升晚期和下降早期，不利于储集砂体发育，仅出现少量薄的水下分流河道、水下决口扇、远—河口砂坝砂体。

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。
