遥感在生态环境质量监测与评价中的应用现状研究

Review and Research Progress of the Application of Remote Sensing in Ecological Environment Quality Monitoring and Evaluation

  • 摘要: 遥感具有快速、实时、监测范围广等特点,在生态环境质量监测与评估方面发挥了重要作用。对国内外1993—2020年间该领域相关文献进行研究。结果表明:在指数方面,能表征植被状况的植被指数(如NDVI等)、能表征城市化状况的建筑指数(如NDBSI等),以及能表征区域人类活动的地表温度(LST)被广泛应用于生态环境质量监测与评价;在模型方面,更能综合反映生态环境质量的综合指数模型(如RSEI等)是当前生态环境质量监测与评价中常用的模型;在评价方法方面,以主成分分析法为代表的客观赋权法是当前生态环境质量评价的主流方法。结合多源遥感数据和综合指数模型多视角定量评估区域生态环境质量和利用长时间序列数据动态监测生态环境质量变化是当前研究的热点。

     

    Abstract: Remote Sensing(RS), with its advantages of rapid, real-time, and large-scale monitoring, has been widely used in the monitoring and evaluation of Ecological environment quality(EEQ). The domestic and international literature about the application of RS in EEQ monitoring and evaluation from 1993 to 2020 were analyzed. The research shows that vegetation index such as the Normalized Difference Vegetation Index(NDVI), building index such as Normalized Difference Built-up and Soil Index(NDBSI), and Land Surface Temperature(LST), which can respectively represent vegetation condition, the status of urbanization, and regional human activities, are widely used in EEQ. Comprehensive index models such as the Remote Sensing Ecological Index(RSEI) are commonly used in EEQ monitoring and evaluation. The objective weighting method represented by principal component analysis(PCA) is the mainstream method of EEQ at present. Additionally, combining multi-source remote sensing data and comprehensive index models to quantitatively assess the regional ecological environment quality from multiple perspectives and dynamically monitor the ecological environment quality changes using long time series data are hot topics of current research.
