摘  要：
本文通过对昌黎监控区11个生态监控指标的分析,利用ArcGIS10.0对昌黎生态监控区各水体因子进行Kriging插值处理,运用景观格局指数方法分析昌黎生态监控区水体环境,分析昌黎生态监控区景观格局的改变以及由此产生的生态环境效应、讨论其海洋景观与生态过程之间的关系。研究表明:10年间人类活动对昌黎县水域生态环境影响显著,昌黎海域水体富营养化严重,水环境遭到严重破坏。水体中N、P含量高、富营养化严重;生物多样性下降;适合文昌鱼生存的砂质底所占百分比逐年退化,国家二级保护动物文昌鱼生物量呈退化趋势。海水养殖、采砂和旅游开发等活动均对该海域生态环境造成影响。应明确海水养殖环境容量、对昌黎生态监控区内挖沙船进行管理,加强渔业资源保护,合理进行海洋开发活动,维持海洋生态系统的多样性。

摘  要：
Based on the analysis of the 11 ecological monitoring indexes in Changli ecological monitoring area,the water body factors of Changli were subjected to Kriging interpolation by using ArcGIS10.0.The landscape environment,biological environment and environment in Changli area were analyzed by landscape pattern index method.The changes in landscape pattern in Changli ecological monitoring area and the ecological environment effect are analyzed.The relationship between the marine landscape and the ecological process are discussed.The study shows that the human activities have a significant effect on the ecological environment of Changli County in 10 years.The content of N,P in water was high,the eutrophication of water in Changli sea area is serious and the water environment has been seriously damaged.The biodiversity was decreased.The percentages of sandy bottom suitable for the survival of amphioxus were degraded year by year.The biomass of amphioxus was degraded.Mariculture,sand mining and tourism development activities have affected the ecological environment of the sea.It is clear that the management should be strengthened for the environmental capacity of marine aquaculture,the dredging vessels,the protection of fishery resources and the reasonable marine development activities in order to maintain the diversity of marine ecosystems.
