    Abstract:

    Based on the observation data of climate and air quality, satellite remote sensing and geographic information data, and relevant urban planning data, the wind environment, the thermal/cold environment and atmospheric environment in Chengdu are comprehensively analyzed. The results of study have been applied to the Chengdu 2049 Urban Strategic Planning. The results show that: (1) The dominant wind direction in Chengdu is northeast, and the wind speed in winter is the smallest. In the urban area, the wind speed is decreasing from northeastern to southwest. The estuaries of the Minjiang River and Jianjiang River in the western Longmen pediment region are two main vents in Chengdu. The wind speed of the centralized urban construction area decreased in the 2000s significantly relative to the speed in the 1980s and 1990s, decreased by 0.5 m/s in the northeast and northwest. (2) The strong heat island and the relative strong heat island area increased from 53.6 km2 in 1992 to 798 km2 in 2014, and the center of heat island presented multipolarization. The highgrade ecocold sources were concentrated in the Longmen Mountain and Longquan Mountain. Highintensity urban construction and slope farmland development are the main reasons for the deterioration of the thermal environment. (3) The atmospheric environment in Chengdu is not good and the spatial distribution of air pollution shows a decreasing trend from the central urban area, the inner suburbs, to the outer suburbs. During the period of 2007 to 2014, the annual mean concentrations of PM10 and NO2 in the urban areas exceeded the Grade II national standards for air quality. (4) The urban climatic analysis map of Chengdu is drawn up, and the urban climatic recommendation map is presented by combining with field investigation, land use status quo and development demands. Finally, the proposals for the 2049 Urban Strategic Planning in Chengdu are put forward.
