Human activities and the demand for biomass and biobased energy can lead to changes in land use. Songyuan City is a typical farming-pastoral ecotone in northeast China, to investigate the land use change in this area, the Landsat TM/OLI remote sensing images in 2000, 2010 and 2019 were analyzed. The land use in the ecotone in 2030 was predicted, as well as the changing characteristic of its ecosystem services value (ESV). The results showed that paddy field has had the highest annual growth rate and the ESV has increased by 338.6 million Chinese Yuan (CNY) in the past 19 years. The areas of dry field, paddy field, water bodies, wetland, and building land showed an upward trend with the dry field having the most growth of 49,596 hm2, whereas the areas of forestland, meadowland, and unused land showed a downward trend; and ESV increases from 3.5714 billion CNY in 2010 to 3.6236 billion CNY in 2030. Accuracy check and sensitivity analysis indicated a reliable result, which could provide reference to the ecologically sustainable development.

We replaced the outdated land-use of the Weather Research and Forecasting-Chemistry (WRF-Chem) model with a refined dataset, the Global Land Cover 2009 (GLC2009) dataset, to investigate the impact of land-use change on the regional atmospheric environment in the Pearl River Delta (PRD) region. Simulations of two months in 2014 (January and July) showed that land-use change increased the monthly averaged 2 m temperature by 0.24°C and 0.27°C in January and July, respectively. The relative humidity decreased by 2.02% and 2.23% in January and July, respectively. Due to the increase in ground roughness, the monthly averaged wind speed in January and July decreased by 0.19 m/s and 0.16 m/s. The planetary boundary layer height increased throughout the day and with larger relative increase during the nighttime. These subtle changes caused by land-use resulted in discernable changes in pollutant concentrations. Monthly averaged surface O3 concentration increased by 0.93 µg/m3 and 1.61 µg/m3 in January and July, while PM2.5 concentration decreased by 1.58 µg/m3 and 3.76 µg/m3, and the changes in pollutant concentrations were more noticeable during the nighttime. Overall, the impacts of land-use change on the atmospheric environment are obvious throughout the PRD region, especially in the urbanized areas.
