Along with the urban construction land expanded in recent years, Urban ecological environment has been becoming an outstanding problem. Therefore, the study on the construction land expansion effects on surface characteristic parameter is very important. This paper took the main urban district of Chongqing as research site. By using 1988, 2000, 1988 LandsatTM 1∶50 000 DEM data and remote sensing data, and based on the method of man-machine interactive interpretation and the technology of quantitative remote sense, the data of land use status and three surface characteristic parameters—land surface temperature, NDVI, soil moisture were obtained, and the influence of the urban construction land expansion characteristic parameters on the surface was analyzed.The results show that: from the 1988—2011, the construction land of the main urban district of Chongqing was mainly expand to the west and north, the high surface temperature has mainly migrated towards to north, NDVI and soil moisture in the area of construction land expansion declined; correlation bwtween the urban construction land expansion and the change trend of surface characteristic parameters was obvious, the positive correlation between thermal environment was significant, and the expansion of construction land was highly consistent with the extension direction, and the relationship between NDVI, soil moisture and the expansion of construction land was negatively correlated. The results can provide the scientific basis and reference for improving urban surface thermal environment effect, optimize the urban ecological environment.
