摘要:
数字化管理是21世纪信息管理的主要方式，构建数字流域将成为黄土高原土壤侵蚀研究、土地利用/土地覆被变化、流域生态环境动态监测等重要的分析和信息管理平台。我们应用GPS技术在黄土高原固原、安塞、长武三个不同地貌与生态区，在复杂地形条件下进行了三维空间定位的试验研究。以固原试区为例，对GPS定位精度、工作效率及在黄土高原数字流域建设中的作用、意义进行了研究和探讨。
Abstract:
Digitalized management is the main management way in the 21st century. Building digital watershed will be the key of improving precision and effciency on dynamic inspection and analysis to soil erosion and land-use change and land planning etc. A successful experiment to build digital watershed in Guyuan, Ansai and Changwu experiment and demonstration section is conducted, in which GPS has made important role. The key methods of 3-dimension positioning with GPS are presented, and its roles and significance in construction of digital watershed are analyzed and discussed.
