In order to realize the sustainable utilization of wetland resources,conservation management and wetland restoration,the landscape pattern change of mangrove forest wetland in Qi'ao Island was analyzed.With ERDAS software,three temporal remote sensing imageries (in 1988,1995,2002)were processed by expert classification method.The landscape metrics/indexes,such as total number of patches,mean patch size,average patch perimeter/area ratio,total edge density,mean patch fractal dimension,mean shape index,largest patch index,total area,total edge,were calculated by Fragstats301 software.The results showed as follows: 1) The area of mangrove forest presented rise trend,the area was 2016 hm~2 in 1988,2808 hm~2 in 1995,5796 hm~2 in 2002,which was mainly induced by the reforestation engineering since 1999.2) Disturbed by human activities,total number of patches increased from 1 in 1988 to 18 in 2002,total patch edge density increased from 23613 in 1988 to 178079 in 2002,average patch perimeter/area ratio increased from 3106796 in 1988 to 8733572 in 2002.This showed the fragmentation of mangrove forest landscape enhanced by human-induced activities.3) Mean patch fractal dimension decreased from 11505 in 1988 to 10578 in 2002,mean shape index decreased from 22857 in 1988 to 15050 in 2002,which showed the complexity of patches decreasing by human disturbance.In the future,some regulating and controlling countermeasures should be put forward for mangrove forest wetland multi-function landscape pattern.

该文分析近20a来淇澳岛红树林湿地景观格局演变,采用遥感和GIS相结合的方法,利用遥感图像处理软件ERDAS对3个时相(1988年、1995年、2002年)的LandsatTM遥感图像应用专家系统方法分类;结合ARCGIS8 1,辅助FRAGSTATS3 01景观软件计算斑块和类型水平上的景观格局指数。淇澳岛红树林面积呈上升趋势,1988年、1995年和2002年分别为20 16hm2、28 08hm2、57 96hm2;斑块数目从1988年的1个增加到2002年的18个,总斑块密度、平均斑块周长面积比呈上升趋势;平均斑块大小、平均斑块分维数、平均斑块形状指数呈下降趋势。近20a来淇澳岛红树林湿地景观受人为干扰,景观破碎化程度不断扩大,需对湿地多功能景观进行科学调控。

The evolution in the mangrove forest wetland landscape and its drive forces within Qi’Ao island where is in the Pearl River Estuary were analyzed. The integrative methods including literatures researching, three temporal phrases (1988, 1995,2002) remote sensing images data were analyzed and field survey were adopted in this paper. By literatures researches, three main evolution stages, including silt tidal flats, mangrove forest tidal flats, mangrove forest plain, were undergone. By remote sensing data in 1988, 1995 and 2002 to be as basic information resource and with the support of GIS, the dynamic development of mangrove forest wetland landscape pattern was analyzed. Currently, about 200 hm 2 of mangroves are present in Qi’Ao island in 2004. These mangroves are important ecosystems, but are subject to disturbance from a number of sources. In recent 25 years, there has been a loss of more than 77 hm 2, as a result of natural losses and mangrove clearing (e.g. for urban and industrial development, agriculture and aquaculture). However, areas of new mangroves have been established by mangrove introduction and afforestation especially since 1999. These new mangroves have mainly appeared in the Dawei bay of Qi’Ao islands. The results showed that the spatial patterns and species composition of mangrove patches have been changed. The biodiversity of mangrove forest species has obviously been declined, the dominant mangrove species is Sonneratia apetala . In addition, mangrove forest wetland vegetation biomass was calculated by field survey. Based on the synthesis analysis, according to the view of ecosystem management, four countermeasures for regulating and controlling, which aim to construct mangrove forest ecological sequence and the biodiversit of mangrove forest wetland vegetation, were put forward: 1) to construct the typical succession model by dealing with the relations between the vegetation biodiversity and competition; 2) to strengthen the environmental policy research for Qi’Ao islands mangrove forest wetland; 3) to build up an early warning system for considering ecosystem vulnerability of mangroves; 4) to develop ecotourism by planning Qi’ao islands mangrove forest wetland park scientifically.

对珠江口内伶仃洋淇澳岛红树林湿地的变化及其驱动力进行了分析。采用的方法包括收集部分历史资料、三个时相段红树林的遥感图像监测和实地样方调查。根据 2 0 0 4年最新遥感测算 ,大约有 2 0 0hm2 红树林生长在该岛 ,这些红树林是珠江口重要的生态系统 ,但已受到强烈人为干扰。在过去近 2 0年里 ,约 77hm2 的天然红树林被毁掉 ,用于水产养殖、城镇基础设施建设。近些年来研究区红树林面积不断增加 ,尤其是自 1999年实行红树林人工恢复工程以来 ,新引种的红树林 (无瓣海桑Sonneratiaapetala)得以重建。但是淇澳岛红树林斑块的空间格局和种的构成发生了变化 ,红树林群落植物多样性明显减弱。在综合分析基础上 ,根据生态系统管理的思想 ,提出了以构建典型的红树林生态序列和红树林湿地植被多样性为目标的淇澳岛红树林湿地生态系统恢复和建设的建议。
