国产HJ-1B卫星数据的地表温度及湿度反演方法——以呼伦贝尔草原伊敏露天煤矿区为例
Retrieving land surface temperature and soil moisture from HJ-1B data: A case study of Yimin open-cast coal mine region in Hulunbeier grassland
摘要
Abstract
The soil moisture can be considered as an appropriate indicator to investigate the level of ecological environment disturbance resulting from mining activities in semi-arid grassland.The main objective of this research is to explore the applicability of Chinese HJ-1B data for LST and soil moisture monitoring around mining-affected areas on the local scale.The JM&S, Qin and Artis methods for temperature retrieval were comparatively analyzed.The relationship space of NDVI-LST was used to generate temperature vegetation dryness index(TVDI).Furthermore, the reference data including in situ soil moisture and MODIS LST products were used for "dry edge" correcting of TVDI.Some conclusions have been reached: The Qin's mono-window algorithm performs best in LST retrieval from HJ-1B data;there is a highest correlation between corrected TVDI value with C=0.3 and in situ soil moisture value;the feature of NDVI-LST space indicates that there is a linear relationship for "wet edge", while the relationship for "dry edge" is conic;the TVDI imagery and LST imagery show different drought conditions of different features.The obvious geographical heterogeneity has been found from the TVDI and LST imagery in this area as well.关键词
