摘要/Abstract

摘要： 地理分析模型是对现实世界中地理过程的抽象与表达，是虚拟地理环境能够反映真实世界的重要工具。随着地理学的发展，跨领域、多学科合作式地理建模逐渐成为地理学的研究趋势，地理分析模型共享与重用也已经成为研究热点之一。然而，地理分析模型运行平台的差异性导致了其在共享与重用上存在困难，表现在用户难以直接透明共享不同平台下的模型。目前，地理分析模型运行平台主要包含Windows与Linux，Linux平台上存在大量模型，但相关模型服务共享与重用研究相对较少。本文面向Linux平台不同操作系统，分析其差异性及安全性，设计模型服务化的安全策略；面向Linux平台下地理分析模型的异构特征，设计了模型基本信息描述接口、行为接口及部署接口，实现Linux系统下地理分析模型的服务共享与重用。本文以system for automated geoscientific analyses（SAGA GIS）中的网格分析模型为例，对所设计的Linux平台下地理分析模型服务化封装方法进行了验证，显示了所设计封装策略的可行性，为Linux平台下地理分析模型的共享与重用提供了理论与方法基础。

Abstract: Geo-analysis models are the abstraction and expression of real-world geographic phenomena and processes.Multidisciplinary and collaborative geographic modeling is currently becoming a main research trend in the field of geography.The service-oriented sharing and reuse of geo-analysis models have become a research direction.However,the heterogeneities in operating platforms lead to difficulties with the sharing and reuse of geo-analysis models.At present,the operating platforms for geo-analysis models mainly include Windows and Linux.A large number of geo-analysis models are developed depending on Linux,but there is less research related to the service-oriented sharing and reuse of these models.This article aims to analyze its differences and security and design a service-oriented security strategy for geo-analysis models on different Linux operating systems.Given the heterogeneities of geo-analysis models for Linux,the basic information description interface,behavior interface,and deployment interface were designed for the service-oriented sharing and reuse of geo-analysis models.The grid analysis model in the system for automated geoscientific analyses (SAGA GIS) was used as an example to demonstrate a service-oriented encapsulation method for geo-analysis models for Linux and validated.In summary,the proposed study can contribute to the theory and methods for the sharing and reuse of geo-analysis models on Linux.
