摘要利用美国陆军土地清查和监测项目的实地数据，研究了利用卫星图像估算大型复杂牧场植被覆盖量的实用性。用于本次调查的研究区域是位于华盛顿中部的美国陆军亚基马训练中心。亚基马培训中心的土地状况-趋势分析（LCTA）计划有202个永久地块，以随机分层的方式分布在整个设施中。沿着样带采取的主要措施是冠层覆盖和地面覆盖。分析中使用了1992年5月和8月收集的陆地卫星专题制图仪图像。卫星数据与实地数据收集期的开始和结束时间相吻合，并用于推导各种植被指数，包括Ratio、TVI、SAVI和MSAVI。分析了牧场覆盖措施和卫星图像得出的植被指数的相关性。植物之间的相关性
Abstract Using field data from the U.S. Army's land inventory and monitoring program, a study was conducted to examine the utility in estimating the quantity of vegetation cover with satellite imagery across a large and complex rangeland. The study area used for this investigation was the U.S. Army's Yakima Training Center in central Washington. The Land Condition‐Trend Analysis (LCTA) program at Yakima Training Center has 202 permanent plots located in a randomly stratified manner across the installation. The principle measures taken along the transects were canopy cover and ground cover. Landsat Thematic Mapper imagery collected in May and August of 1992 was used in the analyses. The satellite data coincided with the beginning and end of the field data collection period and were used to derive various vegetation indices including Ratio, TVI, SAVI, and MSAVI. Analysis of correlation of rangeland cover measures and satellite imagery derived vegetation indices were performed. Correlation between the vegeta...
