Furthermore, in order to improve the interpretation of the deltaic sedimentary record, e.g., to identify climate and environmental changes using the record, the various parameters derived from analyses of the cores should be standardized by evaluating the temporal changes caused by early diagenesis and decay, and by determining the rate of deltaic shoreline changes which control the relative position of the record within the deltaic sedimentary system.

此外，在长江三角洲沉积记录的分析方面，为了更好地提取气候、环境演化信息，应充分考虑沉积记录形成后所经历的自身变化（如成岩作用变化、分解和衰变等）和相对于岸线迁移的空间位置变化。
