基于时间序列遥感数据的植被覆盖度反演研究

Study on Retrieval of Vegetation Coverage Based on Time Series Remote Sensing Data

基于案例分析,阐述时间序列遥感数据的植被覆盖度反演,结合GIS和RS技术,采用像元二分模型提取估算植被覆盖度,通过数理统计方法得到植被覆盖率的变化规律,从而为研究城市生态环境变化状况提供参考,并对城郊地表环境的改善及建设提供参考依据。

Based on the case analysis, this paper expounds the vegetation coverage inversion of time series remote sensing data. Combined with GIS and RS technology, the pixel dichotomy model is used to extract and estimate the vegetation coverage, and the change law of vegetation coverage is obtained through mathematical statistics, so as to provide a reference for the study of the change of urban ecological environment and the improvement and construction of suburban surface environment.
