地球表层建模研究进展
摘要:

本文在讨论地球表层概念和地球表层建模定义的基础上,总结分析了地球表面形态表达、地球气候系统模拟、生态系统空间模拟分析和地球表层模拟系统等主要研究进展。分析结果表明,误差问题、多尺度问题、地球表层模拟速度问题和三维实时可视化问题是地球表层建模面临的主要挑战。为了解决这些问题,必须发展和采用诸如以遥感数据为初始场、以地面实测数据为优化控制条件的高精度高速度曲面建模新方法和新思路。

Progress in earth surface modeling?
Abstract:

A defi nition of earth surface modeling is proposed on the basis of discussing the concept of earth surface. Studies on earth's surface topography modeling and climate system modeling are reviewed, which indicates that it is eagerly necessary to develop simulation methods with high speed, high accuracy and low memory requirement. Introduction of methods for high accuracy and high speed surface modeling (HASM), developed by means of the fundamental theorem of surfaces, might be an effi cient way to characterize the states of earth-surface and changes in those states.
