摘　　要：本文设计了基于GIS的具有"自适应"功能的三维古海面-地面演变模型。该模型可以动态演绎沿海地区"沧海桑田"的变化景象,并且可以运用历史资料及专家知识,对海面-地面变化模拟结果进行检验,根据检验结果来对模型的一系列控制参数进行自动半自动的修订,然后重新进行海面-地面演变的动态模拟,直到更趋近于真实的历史演变过程,从而实现模型的"自适应"调整。与其他模型相比,该模型具有计算控制相对准确,能够方便的进行反复模拟、验证计算,模型能自动、半自动地控制调整计算参数等的特点。运用该模型对长江三角洲地区一万年来的海面-地面系统的变化进行了反演模拟,取得了较好的模拟结果。The expression and recognition of geographical environment,the recovery and reappearance of ancient geographical environment have been the focus in some research fields such as geography,cartography,cognitive science and artificial intelligence.As well,virtual geographical environment and the expression of multidimensional spatio-temporal information have become important research directions with the development of GIS.The reconstruction of sea surface change has long been a focus of geography,and in the past years the prediction of sea surface change has also received considerable interest.The recent development of GIS provides the opportunity for the dynamical simulations of sea surface change as well as for its visualizations.It is also an important research direction in the development situation to build the model with functions of forecast,influence and countermeasure,based on the research of the sea level historical change.This model can provide an effective method for sea level change research.In this paper we present an adaptive 3D Old Sea Level-Land Surface Change Simulation Model based on GIS for the above purpose.This model can be used to simulate the old sea level-land surface evolution over coastal regions.With historical records and expertise knowledge,this model automatically verifies the simulation results and adjusts the parameters which controls the simulation;and then iteratively repeats the simulations until the results become close to the recorded history of old sea level-land surface evolution.Compared with other models,this model has the following features： relatively accurately controlling calculation,easily repeating simulations,automatically verifying the calculation results and automatically/semi-automatically adjusting the parameters.We used this model to simulate the old sea level-land surface change of the Yangtze River delta in the past ten thousand years,and it demonstrated pretty good performance.
