Land surface temperature fluctuation characteristics and key influencing factors in estuarine wetland
Translated Abstract
We analyzed land surface temperature (LST) fluctuation characteristics in urbanization based on retrieval of LST, profile analysis and model construction in the wetland distribution area of Minjiang River. The results showed that: (1) Dramatic changes in land use/land cover had occurred from 1993 to 2016 in this area. The area of water, forest, grassland, cropland, and wetland decreased, while the built-up land increased. Especially, the area of wetland decreased from 37.00 km2 to 29.15 km2. (2) The LST varied with different land use types. For instance, built-up land and bare land had positive contribution on LST rise, while waters, forest, grassland, and wetland had opposite effects. The LST increased during wetland deterioration, which had a negative impact on cooling effect. (3) The urban expansion transformed wetland to built-up land, which played a key role in the fluctuation of LST. (4) There was a negative correlation between LST and normalized difference vegetation index (NDVI) and normalized difference moisture index (NDMI), and a positive correlation between LST and normalized difference impervious surface index (NDISI). (5) The NDMI and NDISI played a greater role in LST than did NDVI. The results would be helpful in estuarine wetland conservation in the future.
