- Abstract:
-
Large-scale development of urban land use has led to change of a variety of natural processes and ecological processes,resulting in complex eco-environmental consequences.The change information of urban land use was extracted and analyzed based on RS (remote sensing) and GIS.The data on environmental impacts of urban land use were extracted and analyzed by overlaying layers of urban land use and the chroma resulted in sampling point data of nitrogen dioxide and total suspended particulate matter concerning to the air quality of the environment in Chengdu based on GIS spatial analysis method.The result showed that the main feature of land use change was a substantial reduction of arable land and construction of land and woodland increased significantly within the study area from 1992 to 2008.The temporal-spatial change was notable in study period.Impact of land use on urban air environment was significant,nitrogen dioxide chroma change resulted from woodland was obvious,the area occupied by different nitrogen dioxide chroma was the largest.The impact on the highest class chroma of total suspended particulate matter from the urban land use was notable and its area was maximum.The result also showed that the spatial chroma distribution of nitrogen dioxide and total suspended particulate matter in study area from Qingbaijiang district-Xindu district-downtown to both sides following reduction.The spatial distribution of urban land use and mining and transportation land use are basically the same spatial chroma distribution.Therefore,the results of this study provide a scientific basis for improvement air environment quality,the urban sustainable development and a scientific response for decisions from the municipal governments.
