| 摘 要： | 宏观水土保持监测是水土保持监测两大重要分支之一 ,在水土流失严重威胁区域生态环境的中国具有重要意义。它在监测目的、对象、方法和手段等方面与微观监测都有显著区别。关于宏观水土保持监测的理论问题可以分为关于理论的研究和区域水土保持动态及其环境影响研究 ,而且都体现出其研究尺度的明显影响。目前在我国其研究和实践发展很快 ,多数研究都应用了遥感和 GIS方法 ,但基本理论研究还很缺乏。随着我国水土保持监测网络的建成和地球信息技术的进步 ,宏观水土保持监测研究的地位和作用将继续得到加强

| Abstract: | As an essential branch of the soil and water conservation monitoring, the macroscopic monitoring for soil conservation is the critical data source in China, which is undertaking the threaten of serious soil erosion. The macroscopic monitoring has significant difference with the microscopic monitoring in their aims, monitoring objects, methods, and technologies. The related research work include 2 fields: research about theory, and regional dynamic and relevant environmental impacts of soil erosion. Research on these theories develops fast in China, and RS GIS methods have been applied by most research work. However, the study on basic theories still is almost absent. With the national monitoring net for soil and water conservation constructing, and the Geomatics technologies developing, its booming perspective will be displayed. |
