摘　　要：基于遥感与GIS技术,运用景观生态学的原理与方法,选取景观特征指数,通过历史回顾和类比分析,从景观自然性和景观破碎化两个方面,分析了兴化湾围填海工程对湿地景观生态造成的影响及其生态效应.历史上兴化湾围填海工程造成滩涂湿地景观萎缩、景观自然性急剧下降,斑块面积缩小、斑块隔离程度增大、景观破碎化程度加剧;兴化湾围填海规划的实施,将使得兴化湾湿地景观生态人工化与破碎化的趋势进一步加剧,其最终后果将可能导致兴化湾生物多样性下降、生态服务功能严重衰退.With landscape ecology theory and methodology, landscape indices were selected to described the landscape change in Xinghua Bay using RS and GIS-tech. Impact of reclamation on wetland landscape and its ecological effects in Xinghua Bay were analyzed in terms of landscape naturalness and landscape fragmentation. Historical reclamation in Xinghua Bay had seriously modified the wetland landscape where tidal fiat wetland diminished, landscape naturalness declined ,patch area reduced, increasing patch isolation, landscape fragmented are common phenomenal. The implementation of reclamation planning will bring more artificial fragment in Xinghua Bay. As results, bio-diversity and ecological service functions deteriorate.
