Characteristics Of Temporal And Spatial Variation Of Ndvi In Beijing And The Relationship With Urban Heat Island Effect, Wenye Liang

Sustainability and Social Justice

Vegetation is an important part of ecosystems, and the use of vegetation coverage as an indicator to study the spatio-temporal dynamics of regional vegetation is necessary for ecosystem health evaluation. The urban heat island effect can change the structure and functions of urban ecosystems, and affect the climate, hydrology, atmospheric environment, and energy metabolism of cities, as well as the health of residents. Using Beijing as a case study, this research generates vegetation coverage maps using remote sensing imagery from 1998, 2003, 2008, 2013 and 2018. This study indirectly analyzes the urban heat island effect through spatio-temporal changes in vegetation …
