| 摘 要： | 本研究以分形理论为基础,并借助GIS、RS技术,利用1986年和2002年两期TM遥感影像,提取获得了1986年和2002年闽江河口湿地资源的空间信息,根据分形理论中分形维数和稳定性指数的物理意义,揭示了闽江河口湿地资源动态变化情况。研究表明:闽江河口的湿地类型具有分形结构.并且由于受到较强的人类活动的干预,湿地斑块的形状较为复杂,且稳定性较差。

| Abstract: | Based on fractal theory,spatial information on wetland resources of 1986 and 2002 in the estuary of Mingjiang River was obtained from TM images of 2 respective years by means of GIS and RS technologies. The fractal dimension and stability index were analyzed to reveal the dynamic changes of wetland resources in the estuary of Mingjiang River. The study indicated that many wetland areas changed into non-wetland. On the whole,the patches of various wetland types were complicated in shape and poor in stability.It was believed that the decreased wetland resources and poor stability were mainly due to ignorance of wetland protection during the urban development in Fuzhou. |
