【摘要】 提出了以归一化植被指数NDVI作为变量,通过比较短期内的植被指数变化,来实现植被的动态监测,同时借助强大的时态GIS性来探讨适合短时间内进行植被动态监测的时空索引模型方法,解决动态监测过程中的时间和空间的对应关系问题,同时对植被动态监测结果进行模拟显示。更多还原

【Abstract】 NDVI(Normalized Difference Vegetation Index)was taken as a factor to monitor the vegetation by compared with the difference of NDVI in short time.At the same time,the dynamic evolvement model was built to adopt the short time vegetation monitoring supported by the mighty temporal GIS,so the model can resolve the corresponding relation of time and spatial and can simulate the results of vegetation monitoring.更多还原
