基于劈窗算法暨马尔科夫模型的岩溶区地表温度混合反演剖析
Hybrid inversion method of karst area based on LST split window algorithm & Markov model
摘要
Abstract
Remote sensing method can predict the ground temperature quickly and its change regulation.But there are shortcomings in many methods for their regional specificity.In order to explore the remote sensing prediction model for ground temperature change in typical karst cities,this paper takes the typical karst landforms of Yanshan area in Guilin as an example.With the help of four Landsat data and some historical meteorological data,the window temperature is extracted and iterated by remote sensing image.The ground temperature data are normalized and combined with Markov prediction model to study the change of urban ground temperature.The results show that the change of the overall heat island effect in the study area is not obvious,indicating that the ground temperature effect by artificial development in the karst area is not significant.In the eastern part of Lijiang River,which is bounded by the Lijiang River,the change is slowed down.The results show that the split window algorithm combined with the Markov prediction model is an optimal combination of the urban heat island effect in karst landform area,and can reveal the temporal and spatial variation of urban heat island effect.关键词
