应用RS和GIS技术监测石漠化的研究

在介绍石漠化及其危害的基础上,阐述了基于RS和G IS技术监测石漠化的意义、应用RS和G IS技术监测石漠化的研究现状和监测方法,提出目前存在的主要问题:①石漠化调查资料缺乏;②应用RS和G IS技术监测石漠化还没有形成较合理、完善的研究方法,也谈不上信息共享和实际应用;③还没有建立基于RS和G IS技术的石漠化预警预报模型和运行系统。建议加大采用RS和G IS技术对石漠化的研究工作力度,探索石漠化遥感调查监测的实用技术,建立石漠化预警预报模型和运行系统,同时采用新机制,增强石漠化调查与评价的服务意识。

Study on Monitoring Rock Desertification by Applying RS and GIS Technology

The paper elaborates the significance of rock desertification monitoring of RS and GIS-based techniques and the present study and monitoring methods for rock desertification monitoring by utilizing RS and GIS techniques and puts forward the main existing problems at present based on the introduction of rock desertification and its harmfulness: a) the survey data on rock desertification is insufficient;b) monitoring rock desertification by applying RS and GIS techniques has not yet formed as a rational and perfect study method to say nothing of information sharing and practical application and;c) rock desertification forecasting and warning model and an operational system of RS and GIS-based techniques have not been established.It suggests to strengthen the momentum on rock desertification study by using RS and GIS techniques,explore the practical technique of survey and monitoring rock desertification by remote sensing,establish a rock desertification forecasting and warning model and an operational system and increase the sense of service for investigation and evaluation by using a new mechanism.
