摘要:
利用2000年冬季和2001年夏季两个时相的卫星遥感TM影像数据,结合详细的野外实地考察与验证,估计了北京平原地区主要裸露土地类型的空间分布和面积.结果表明,冬季裸地的总面积是夏季的5.5倍.在各类裸地中,以裸露农田的面积最大,成为导致北京冬、春季节沙尘污染最重要的本地沙源.此外,沙荒地、建筑工地和其他裸地是引起局部地区沙尘污染的本地沙源.为了控制北京地区的沙尘污染,需要建立城市森林体系和调整耕作方式.
Abstract:
On the basis of the Landsat TM Images of the winter 2000 and summer 2001,and detailed field investigation and validation,the spatial distribution and the area of main bare land types in the plain areas of Beijing were estimated.The results show that the total area of bare land in winter was about 5.5 times of that in summer.Among all kinds of bare land types,the area of bare farmland is the largest.Therefore,the bare farmland becomes the most important local sand source that induces the sandy dust pollution during winter and spring in Beijing.In addition,sandy badlands,construction building sites,and other bare land are local sand sources that cause the sandy dust pollution of partial areas.In order to control the sandy dust pollution in Beijing,an urban forest system should be established and the cultivated manner should be adjusted.
