山地丘陵区土壤侵蚀动态监测技术

Soil erosion dynamic monitoring system in highlands and mountainous areas

山地丘陵地区土壤侵蚀严重,需要采取有效的措施进行土壤监测;采用“3S”集成技术,建立山地丘陵区土壤侵蚀动态监测系统;利用RS和GPS技术进行数据采集与更新,以GIS为组织手段对空间数据进行动态的分析和处理,对土壤侵蚀严重及危险区进行预警;以重庆市土壤侵蚀动态监测为例,详细介绍了土壤侵蚀动态监测系统的属性与功能。

In this article, 'RS', 'GIS' and 'GPS' are introduced to integrate the '3S' technology, which are applied in the construction of the soil erosion dynamic monitoring system. This system is used to monitor the soil erosion in watershed and pre-warn the problems hidden in the land utility, so that measures can be taken to solve these problems. Also, with the example of Chongqing`s dynamic monitoring of soil erosion, functions and attribute of the system are explicitly explained.
