摘要
以环青海湖地区为例,详细介绍了该地区主要草地类型完整生育期波谱试验的总过程,并对试验选取的高寒干草原、山地干草原、沼泽化草甸、高山草甸4种天然草地及人工草地生育期内的反射波谱特性进行了分析,为同类目的试验提供了参考和建议。
There are obvious differences between plant types which can be exploited by time series spectral experiments in order to provide information which can play an important role in plant investigation. This paper introduces the overall process of spectral retrieval using as an example an experiment conducted over the growth period of the main grassland types found in the region around the Qinghai Lake. The paper gives an analysis on the spectral characteristics of natural and artificial grasslands in the region, in which mountainous pasture, alpine pasture, sub--alpine meadow and paludification meadow together constitute the natural grasslands. Finaly the paper provides both references and proposals for experiments with the same goal.
