Abstract:: In order to analyze the influence of land use change on surface runoff in the main urban area of Chongqing, based on the SCS hydrology model, the related data such as land use, rainfall, and soil type were selected to simulate the surface runoff during dry, normal, and wet periods under normal soil moisture(AMC Ⅱ)in the early stage. The impact of land use change on surface runoff was analyzed according to the runoff yield capacity, runoff coefficient, and landscape pattern of various land use types. The results showed that:(1)from 2000 to 2015, the land use types in the main urban area of Chongqing City were mainly cultivated land and forestland, and the proportion of these types continued to decline; the cultivated land was mainly transformed into construction land, forestland, and water area, and the construction land area increased by 304.90% and reached 932.55 km² in 2015;(2)the runoff depths in the main urban area of Chongqing City were increasing during the dry, normal, and wet period in which the runoff depths were 0～14.58 mm, 12.70～93.74 mm, 62.45～184.85 mm, respectively;(3)the runoff generation capacity of various land use types in the main urban area of Chongqing City increased in the order:woodland< grassland< cultivated land< unused land< construction land< water area; the areas with increased runoff coefficient mainly distributed in the relatively flat areas between the‘two rivers and four mountains', showing a north-south extension trend; surface runoff had a very significant positive correlation with PLAND, LPI, COHESION, AI of construction land, and a very significant negative correlation with DIVISION and NP, indicating that in the process of rapid urbanization, land use landscape pattern could be rationally planned, and land use structure and spatial distribution could be optimized to control surface runoff.
