A STUDY OF SOIL CONSERVATION MONITORING INFORMATION SYSTEM BASED ON REMOTELY SENSED DATA FOR A CATCHMENT ON THE LOESS PLATEAU

The Soil Conservation Monitorins Information System (SCMIS) presented in this paper is oriented to soil erosion control, resources exploitation, utilization, planning and management for a small watershed (about 10 sq. km.) on the Loess Plateau. It sums up Remote sensing (RS), Geographical Information System (GIS) and Expert System (ES) and consists of a integrated system. As a basic level information system of Loess Plateau, its perfection and psreading will bring about a great advance in resources exploitation and management of Loess Plateau.

大型土遗址保护数据库系统建设研究

大型土遗址是我国文化遗产的重要组成部分，随着我国经济社会的迅猛发展，大型土遗址的保护工作有了更高的目标和更深层次的需求。为了实现大型土遗址的动态监测、管理、保护和研究，以交河故城为例，利用激光扫描建立了交河故城三维模型，采用地理信息系统平台ArcGIS。根据交河故城保护需求，以ArcSDE数据引擎为接口，基于Oracle数据库，建立了交河故城数据库管理系统，实现了交河故城保护数据的有效组织与管理。为遗址的考古、保护科学决策提供了可靠的数据源，为大型土遗址的信息化建设提供了一定参考。
