[目的]进行国产高分1号遥感数据在草地长势监测方面的应用研究,为维持草地畜牧业可持续发展、维护草原生态平衡提供科学依据。[方法]以新疆典型草原区—玛纳斯河流域为研究靶区,在“3S”技术支持下,利用高分一号卫星数据的优越性及野外调查数据,进行国产高分一号遥感数据在草地长势监测方面的应用研究。[结果]研究区2014年草地长势比2013年差一些,2014年长势比2013年差的草地面积为209 074.7hm2,占研究区草地总面积的13.21%。研究区2013—2014年各类草地类型长势情况的结果显示,比2013年长势差的面积最大的草地类型是温性荒漠草原,面积为109 224.6hm2,占温性荒漠草原面积的36.8%,研究区草地总面积的6.9%。[结论]研究区草地长势监测精度比较高,即,88.6%以上,高分1号卫星数据是一个草地长势监测的有效数据。
[Objective] The research aimed to study the application of the domestic highscore No.1 remote sensing data in the monitoring of grassland growth and provide a scientific basis for maintaining the sustainable development of grassland husbandry and maintaining the ecological balance of grassland. [Method] With the typical grassland area of Xinjiang - Manas River Basin as the research target, under the support of “3S ” technology, using the superiority and field survey data of high score I satellite data, Application of Remote Sensing Data in Grassland Growth Monitoring. [Result] The grassland growth in 2014 was worse than that in 2013, and the area of grassland growing worse than that in 2013 was 209 074.7hm2 in 2014, accounting for 13.21% of the total area of grassland in the study area. The results showed that the grassland types with the largest area worse than 2013 were temperate desert steppe, with an area of 109 224.6hm2, accounting for 36.8% of the area of temperate desert steppe. The total area of grassland 6.9%. [Conclusion] The monitoring precision of grassland growth was relatively high in the study area, that is, above 88.6%. The data of high score 1 satellite was a valid data for grass growth monitoring.
