【摘要】 本文主要介绍了喀斯特石漠化动态监测与驱动诊断信息系统(KRD.DMDM.IS)的研制。文章论述了该系统应用的ArcObjects技术及其二次开发层次、一般开发步骤和应用的部分接口,采用了Geodatabase数据模型建立数据库,并将支持C/S体系结构的空间数据库管理器(ArcSDE)集成于系统中来,较好地解决了对空间和非空间数据进行高效率操作的数据库接口;构建了马尔柯夫模型和驱动诊断模型,对广西都安瑶族自治县的石漠化动态变化、演变趋势和形成机制进行了深入分析,从而为该地区的喀斯特石漠化综合治理工作提供有益的帮助。更多还原

【Abstract】 This paper mainly introduces the research of karst rocky desertification dynamic monitoring and mechanism diagnoses information system. It illuminates the technology of ArcObjects, the secondary development level, the general development steps and partial applied interfaces in the system. It adopts Geodatabase model to build the database of the system. The Spatial Data Engine (ArcSDE) which supports the systematic configuration of C/S mode is integrated in the system. Therefore, we can resolve preferably the issues of database interface, manipulating effectively with spatial and non-spatial data. With constructing the Markov model and motive diagnoses model, the paper has tried to make an analysis on the karst rocky dynamic change, inducing causation and evolvement trend in Du’an Yao Autonomous County of Guangxi. It provides a feasible supplementary assist for comprehensive control of karst rocky desertification area.更多还原
