The changes in land cover types will affect the amount of solar radiant energy absorbed by the land surface and then influence the radiative equilibrium of the surface ecosystem. Under the background of dramatic changes in land cover, the patterns and changes of the solar radiation absorptivity of land exert significant influence on the thermal equilibrium of the land surface. Based on the MODIS MCD12Q1 land cover data, the MCD43A3 surface albedo data, and the MCD43A2 solar zenith angle data from 2001 to 2020, along with two adjacent phases of spatiotemporal changes in the surface cover types and the solar radiant energy absorbed by land surface across northwestern China, this study analyzed and explored the impacts of the changes in land cover types on solar radiation absorption. The results indicate that the changes in land cover types in the study area are primarily characterized by reduced bare land area and the expansion of other land cover types, with the largest areal change occurring in the shift from bare land to grassland. Different types of land cover display varying solar radiation absorptivities. Water bodies exhibit the greatest solar radiation absorptivity, followed by woodland, cultivated land, grassland, and construction land, with bare land and permanent ice and snow presenting the poorest solar radiation absorptivities. The conversion of land cover types will lead to different radiation absorptivities. Specifically, the transfer from grassland, cultivated land, bare land, and permanent ice and snow primarily exhibits an increasing trend in solar radiation absorptivity, while that of water bodies and forest land largely displays a decreasing trend. The same land cover type differs in the time series of solar radiation absorption, which primarily increases for construction land, grassland, cultivated land, bare land, and water bodies but decreases for woodland and permanent ice and snow. The results of this study will provide a scientific basis and reference for research on climatic change, ecological construction, and sustainable development in northwestern China.
