To explore the impact of urbanization on meteorological observation and its environment, taking the national climate stations of Shouxian (SX) as an example to investigate the influence of urbanization on land use/land cover (LULC), the thermal environment of the station and the temperature/wind and their relationships are studied by using the Landsat data along with GIS and meteorological data. Results show: (1) The urbanizationinduced LULC change is the main cause of influencing the representativeness of meteorological stations. (2) The urban construction land was the main factor affecting the spatial distribution of the thermal environment around these stations, and along with the propulsion of urbanization, the contribution to these stations of the urban construction land were constantly enlarged. While in low and sublow temperature zones, vegetation and water are the main contributors. (3) Take the new site as the reference station, the higher air temperature and lower wind speed are found at the old site than those at the new site, and the match rate for wind direction is only about 15%, influenced by the rapid urbanization of Shouxian. The effects of urban expansion on meteorological factors present significant diurnal and seasonal variations. Consequently, controlling the scale and layout of the urban construction land around the stations is an effective way to improve stations’ thermal environment and enhance region representativeness.
