基于MODIS影像数据的红原县退牧还草工程效益监测与评价

Benefit Assessment of Project of Returning Grazing to Grass on MODIS Data

为保护日益退化的草原,国家启动了天然草原退牧还草工程。本文以"3S"技术为支撑,利用2005年和2011年的MODIS影像数据,对红原县2005年度实施的退牧还草工程实施效果进行遥感监测,对工程实施进展情况、工程建设效益进行评价,为进一步开展草原资源与生态动态监测和草原生态建设工程效益评价与监测等工作提供科技支持。

In order to protect grassland, the project of returning grazing to grass was carried out. Based on ＂3S＂ （GIS,RS,GPS） technology and land investigation, the benefit assessment of returning grazing to grass was monitored on base of the MODIS data collected in 2005 and 2011. At the same time, the implement of project and the benefit of project was also analyzed and estimated in this paper. It offered a technical model to further process grassland resource dynamic monitor and ecological engineering monitor.
