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。

General layout: General idea should focus on protecting urban water sources, restoring riverways, wetlands and groundwater, improving the water body function, strengthening water resources allocation and water function regions management. Based on existing water project structures, the generallayout follows as that urban water sources conservation on the upriver, wetland and groundwater restoration on mid-river and coastal wetland and estuarine eco-area restoration on the downriver, achieve the target that rivers and lakes 'connection, green bank, clean water, flowing river', then form aquaticecosystem protection and guarantee system.

以保护城市水源地为重点，以修复河道湿地、地下水和改善水体功能为核心，以强化水资源配置和水功能区管理为关键，基于现有的水利工程体系，在流域上游建立以城市饮用水水源地为主体的生态保护屏障，在流域中游建设以湖泊为点、河道为线、地下水为面的水生态修复系统，在流域下游构建以滨海湿地和入海河口为中心的生态恢复区，遏制水土流失，增强水源涵养，保护水功能区，实现河、湖&连通、绿岸、清水、流水&，进而形成防控结合的水生态环境保护与修复保障体系。

As far as the two groups of middle Triassic series turbidite, lower sections of them act as aquifer because they composed of sandstone and siltstone with high sand content, and upper mudstone sections act as aquitard.

中三叠统的两个组百蓬组和河口组的下部为含砂率较高、粒度较粗的砂岩透水层，上部为泥岩弱透水层。

Based on the modeling, spatial variations of the north passage thalweg from 1965 to 2003 are analyzed, and the evolving process of islands in both sides of the passage is discussed thoroughly. On the base of modeling, we design and develop the virtual explore system of the Yangtze Estuary.

文中详细介绍了三维地形虚拟表达过程中的数据格式转换、地形建模、纹理粘贴和模型优化等相关技术细节，为数字河口海岸研究提供了一种新的思路。

The amount and range of sedimentation in the estuary are reduced and the position of maximum sediment thickness point is extended to seawards about 230m.

研究结果认为设置导堤后泥沙在口门附近的淤积范围和数量减少，淤积厚度最大点的位置向外海推进了230m，有利于把河口泥沙输送到深海，效果明显。

The tidal flat along Bohai Gulf extends from Haihe River Mouth to Dakou River. According to the results of field survey, the inter-tidal flat has obvious zonation. From the shore seawards, 4 zones can be identified, and they are depression polygon, inner depositional, erosional and outer depositional zones, and the associated sediment types are mud and clayey mud, mud, alternating laminae of silt and mud, and coarse silt, respectively.

渤海湾潮滩海岸从海河口以南到黄河三角洲北缘的大口河以北，据野外调查发现，这里的潮间浅滩具有明显的分带性，从岸向海可以分为四带，即龟裂带、内淤积带、滩面冲刷带、外淤积带，相应各带的沉积物为：淤泥与粘土质淤泥、淤泥、粉砂与淤泥互层、粗粉砂。
