摘要
遥感在草地监测中的应用,改变了仅靠样方调查的传统模式,使动态、客观、及时的草地监测成为可能.在介绍了草地遥感监测中常用数据来源及其特点的基础上,分析了遥感在草地资源调查、退化动态监测、土壤侵蚀研究和灾害监测方面的应用原理和研究进展,并对未来的发展方向进行展望,以期在总结已有研究成果的同时,汲取经验,发现问题,对今后的研究起到一定的参考作用.
Application of remote sensing （RS） in the monitoring grassland changes the traditional pattern which only relies on quadrat method and makes grassland monitory become dynamic, objective and timely. Firstly, frequently-used RS data and its characteristic were introduced. Then, the principle and research progress on surveying grassland resource, monitoring grassland degradation dynamically, studying soil erosion and monitoring grassland disaster by RS were analyzed. Finally, the future developing direction was mentioned. The aims of this paper are summarization of existing research results, learning from experiences, finding problems and guiding the future research to a certain degree.
