“…Single dynamic degree of LULC reflects the changing rate of some kind of LULCC in a certain time in a study area and plays an important role in comparing regional differences and forecasting the trends of LULCC and is calculated as follows (Sun, Zhang, Liu, & Zhang, ):

K = ((), U_{b} - U_{a}) / U_{a} \times T^{- italic1} \times italic100 %

where K indicates the single dynamic degree of LULC in a certain time, U a and U b indicate the total area of LULC at the beginning and end of study period, respectively. T indicates the length of study period.…”

The agricultural pastoral ecotone of Northern China (APENC), as a fragile ecological zone, has experienced dramatic land use/land cover changes (LULCC) owing to intensive human disturbances. The understanding of the impacts of LULCC on climate, especially the diurnal temperature range (DTR), is not sufficient in this region. The spatio-temporal processes of LULCC and its impacts on DTR were quantitatively analyzed, using the Terra/Aqua MODIS data (MYD11A2 and MCD12Q1, 2003-2013), on the premise of eliminating or weakening the effects of background climate. Results showed that the areas of croplands, forests, and waterbody increased with the annual rate of 2.84%, 0.95%, and 8.2%, respectively, whereas grasslands and bare land decreased with the annual rate of 0.69% and 7.32%, and built-up remained quite stable during the period of 2003-2013. The annual changing rate of LULC for 2008-2013 was nearly 2.84 times the value for 2003-2008. In general, LULC contributed to a decline of DTR over the whole APENC both at monthly/seasonal timescale. Croplands, forests, and mutual transformation between croplands and grasslands tended to decrease daytime maximum temperature (T max ), resulting in a decline of DTR. The grasslands could reduce the DTR by decreasing T max and increasing nighttime minimum temperature (T min ). By contrast, the conversion of grasslands into forests tended to increase T max and decrease T min , thus a rise of DTR for winter, summer, and autumn had observed. These results can assist land resource development and relevant policies making in APENC. KEYWORDS APENC, different timescales, diurnal temperature range, land use/land cover change, MODIS

“…In the current process of urbanization and urban expansion, the structure of land use in urban areas is a growing concern for urban planners [5]. Based on different theoretical perspectives such as economics, sociology, and geography, many scholars have conducted studies on the concept [6], spatiotemporal evolution [7][8][9], driving factors [10][11][12][13][14], projection [15][16][17][18],…”

Shrinking cities are a class of cities that show different trajectories in the urbanization process. Although many studies have examined shrinking cities from multi-dimensional perspectives, the spatiotemporal evolution of land use structure is still poorly understood. This study constructed an analysis framework for spatiotemporal evolution characteristics of land use structure over two 10-year periods based on 334 county-level administrative units in the context of northeast China, a region undergoing substantial population loss and urban shrinkage. This study analyses quantitatively measured population loss and land use conversion and investigated the rationality of the expansion mode of newly added construction land in research units. The results demonstrated that, first, the total population in northeast China continued to decline, but the total construction area continued to grow, and the various types of construction land in most shrinking units did not decline with the loss of population. Second, 67.09% of new construction land came from cropland, and compared with 2000–2010, the growth of new construction land in 2010–2020 slowed down. Third, during the study period, more than half of the expansion area for newly added construction land came from sprawling expansion, and areas in a state of shrinking were no exception.
