摘要 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,提取获得了这两期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,1986~2002年间,闽
江河口区有大量湿地转变为非湿地,总体上看,各湿地类型斑块的形状较为复杂,稳定性差,并且未来有加快演变的趋势。福州市在
实施“东扩南进”的城市发展战略的过程中对湿地资源的直接占用,是导致闽江口湿地减少,稳定性差的主要原因。今后在闽江南、
北港的开发过程中,需要在积极发展经济的同时,加强湿地生态保护。

Abstract :Based on the fractal theory and using GIS and RS technologies, this paper interpreted the TM images of
1986 and 2002 and obtained the spatial information of the Minjiang River weltand resources in different time
intervals. The fractal dimensions and stability indices reveal that the Minjiang River wetland resources have
changed dynamically and that a lot of wetalnds have become non-wetlands in the Minjiang River estuary. On the
whole, the patches of various wetland types are complicated in shape, lack stability, and tend to become
increasingly worse. It is believed that the instability of the Minjiang River estuary wetlands is mainly attributed
to the neglect of wetland resource protection during the urban development in Fuzhou. In future, much more
importance should be attached to the protection of wetland ecology and sustainable development in the exploitation
of the Minjiang River harbors.
