| 摘 要： | 以长江南京段向南北延伸3 km的缓冲带作为研究区域,通过对19861、9962、000年Landsat TM影像进行监督分类,得到3个时期湿地资源变化数据。结果表明,湿地总面积由90.218 hm2减少到79.366 hm2,年均减少0.775 hm2。经过驱动因子分析得出,造成沿江湿地面积锐减主要是人口数量增长以及工程建设的影响,此外还包括沿江各乡镇对湿地资源的不合理利用。最后得出结论:湿地保护要与城镇化发展和谐共存,制定合理的湿地保护规划,对现有湿地资源进行分级分区保护与利用。

| Abstract: | The study is based on the buffer zone of the Yangtze River in Nanjing extension 3 km in the direction of south-north.The change result during three periods of wetland resource was gained through the classification the image of Landsat TM in 1986,1996,2000.The total area of wetland has decreased from 90.218 hm2 to 79.366 hm2.What was the main reason of the reduction by driver factor was analyzed,which was the increment of population and the effect of construction,and the nonsensible utilization of wetland resource along the Yangtze River.The conclusion was that wetland protection and civilization need to be harmonic coexistence,constitute sensible wetland protection planning and do protect and utilize against existing wetland resource. |
