RS与GIS在东北黑土区土壤侵蚀研究中的应用

Application of RS and GIS on Soil Erosion Research in Black Soil Region of Northeast China

东北黑土区是现代土壤侵蚀严重的地区之一。通过对该区域土壤侵蚀的遥感调查监测,基于经验模型的水土流失遥感定量研究等方面的回顾总结,分析了东北黑土区土壤侵蚀研究中存在的问题。提出黑土区应用RS与GIS技术进行土壤侵蚀研究的工作思路:应用现代信息技术开展土壤侵蚀调查评价,研究建立黑土区土壤侵蚀信息图谱,研制东北黑土区土壤侵蚀信息系统,密切土壤侵蚀研究与生态环境建设管理工作的结合。

Black soil region of northeast China is one of areas that modern soil erosion is severest. Remote sensing investigation and monitoring of soil erosion, as well as quantitative remote sensing monitoring of soil erosion based on empirical model were reviewed and summarized. Problems existed in the research of soil erosion were analyzed. Some considerations on the application of RS and GIS technology in black soil region of northeast China were put forward： applying modern information technology to carry out the investigation and evaluation of soil erosion, studying the construction of soil erosion informatic spectrum, developing soil erosion information system, enhancing the combination of soil erosion research and ecological environment construction management.
