The park landscape as the Oases in the city played an important role to the overall and partial urban eco鄄 environment. Based on the thermal infrared remote sensing data, this paper analyzed the relationship between the land surface temperature of seven parks in Xian and the surrounding areas by using the technology of Mono鄄window algorithm and the spatial analysis based on RS and GIS. The results showed that: the temperature differences between the surrounding areas and boundaries of park rise with the distances further away from the park boundaries and growth mode for nonlinear. The parks with the different parameters have different effect on surrounding area of the thermal environment, and park area were decisive factor to the average temperature of parks. The average temperature decreasing range around parks has a positive relationship with the park area of green and water. Specially, when the water proportion over 30% in park, the average temperature decreasing range and the distance far away from the parks were higher than the park with the water proportion less than 30% in the Xi忆an city. Therefore, we should not only consider the shape of the parks, but also should make the water proportion over 30% for the new park construction. In this study we got the features of the parks to the surrounding areas based on the thermal inferred data, which provides a reference and theory basis for the new parks design and construction.
