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。

Article 15 A local government at or above the county level shall compile the draft budget and draft final accounts at the corresponding level, makes report on the draft general budget at the corresponding level to the people's congress at the corresponding level, submit for the record the totalized general budget submitted by the next lower level to the standing committee of the people's congress at the corresponding level for the record, organize the implementation of the general budget at the corresponding level, make decisions to draw on reserve funds of the budget at the corresponding level, work out the adjustment plan for the budget at the corresponding level, supervise the budget implementation by the departments at the corresponding level and by the government at the next lower level, alter or annul inappropriate decisions and orders made by the departments at the corresponding level and the government at the next lower level on budget or final accounts, and submit report to the people's congress at the corresponding level or its standing committee on the implementation of the general budget at the corresponding level.

第十五条县级以上地方各级政府编制本级预算、决算草案；向本级人民代表大会作关于本级总预算草案的报告；将下一级政府报送备案的预算汇总后报本级人民代表大会常务委员会备案；组织本级总预算的执行；决定本级预算预备费的动用；编制本级预算的调整方案；监督本级各部门和下级政府的预算执行；改变或者撤销本级各部门和下级政府关于预算、决算的不适当的决定、命令；向本级人民代表大会、本级人民代表大会常务委员会报告本级总预算的执行情况。

Based on the theory of Sequence Stratigraphy and the systematically analysis of strata which was closely focused on Lithostratigraphy, Biostratigraphy, Paleoecology Event Stratigraphy and Sequence Stratigraphy, four long-term base-level cycles can be recognized in the Mesozoic, each long-term base-level cycles can be further divided into intermediate-term to short-term base-level cycle. Eight intermediate-term base-level cycles are recognized in Mesozoic; Cenozoic can be divided into two structural base-level cycles, and can be further divided into seven long-term baselevel cycles.

应用层序地层学理论，在详细的岩石地层、生物地层、生态地层、事件地层和层序地层为核心的综合地层研究基础上，将中生界划分为四个长期基准面旋回，每个长期基准面旋回内部又可进一步识别出更次一级的旋回，侏罗系内部共可识别出8个次级旋回；根据钻井层序地层与地震地层划分结果，将北缘地区新生界划分为两个构造基准面旋回，其内部又可进一步划分为7个长期基准面旋回。
