摘要
Ecopath model is an important evaluation model in the field of ecological research.At present,Ecopath model is mainly applied in the structure of food web,material circulation and energy flow,environmental capacity and so on.The Ecopath models in ocean,lake and reservoir ecosystems were reviewed,including the ecological nutrient conversion efficiency(EE),ecosystem characteristic index(CI),Niche Overlap and energy flow characteristics of trophic level.The practical significance of Ecopath model in marine ecosystem evaluation and application is expounded by comparing and analyzing the literature data,which provides the technical support for the scientific management of inland ecosystem in the future.
Ecopath模型是生态研究领域一个重要的评价模型,目前主要在不同水域生态系统中食物网结构、物质循环与能量流动、环境容量等方面的应用研究。笔者综述了海洋、湖泊、水库等生态系统中Ecopath模型的相关评价指标,包括生态营养转化效率(EE)、生态系统特征指数、生态位重叠和营养级能流特征等;并归纳总结了该模型的应用范围,通过比较分析文献数据,阐述Ecopath模型在海洋生态系统中评价与应用的现实意义,为今后开展内陆生态系统的科学管理提供技术支撑。
