| 摘 要： | 本文针对不同环境特征参数的空间和时间变化特征,利用2006年不同空间分辨率和时间分辨率的多源遥感数据和产品,对31个奥运场馆、公路自行车赛场和奥林匹克公园的建筑指数、水体指数、白天/夜间陆表温度以及植被指数特征进行了GIS系统分析,其结果:(1)31个奥运场馆的建筑时间、地理位置以及露天情况对其环境特征有着重要的影响,建筑指数、水体指数、白天/夜间的陆表温度以及植被指数均表现出不同的变化特征,故奥运场馆的绿化和赛事安排应对这些因素进行综合考虑。(2)公路自行车赛场和奥林匹克公园均表现出建筑指数较高,水体指数为负值的特征,而且夏季和秋季白天/夜间陆表温度较高。建议在奥林匹克公园适当增加一些水体以提高其环境质量。

| Abstract: | 31 Olympic venues,the road cycling field and the Olympic park of Beijing Olympic Games changed the urban land surface.In order to study the environmental characteristics and the influence of these buildings,several indexes,such as,normalized difference building index(NDBI),normalized difference water index(NDWI),seasonal day and night land surface temperature(LST)and normalized difference vegetation index(NDVI)were analyzed with different spatial and temporal resolution multi-source remote sensing data and GIS,which is helpful to achieve the goal of Green Olympic Games.LANDSAT TM5 remote sensing data with 30m spatial resolution and 16 days temporal resolution was used to extract the information about the NDBI and NDWI,which are not sensitive to time.EOS MODIS remote sensing products with 250m/1km spatial resolution were used to extract the information about the day/night LST and NDVI,which are sensitive to time.The study area for each venue was defined from its center to 1 km outside with the buffer zone analysis of GIS.By classing the Olympic venues into different types based on the building time,the geographical location and the open air states,the indexes of different kinds of venues were analyzed with their mean values and the standard variance.The results lead to the following conclusions:(1)The environmental characteristics of the 31 Olympic venues are different with the difference of their building time,geographical locations and the open air states.It is necessary to take all these factors into consideration in landscaping and the programming of the activities in these venues.(2)The environment characteristics of the road cycling field are close to that of the Olympic park of Beijing Olympic Games.They both present high building index,negative water index and high day/night land surface temperature in summer and autumn.And it is better to add some water body around them to increase the environment quality. |
