The new index FINE, a multimetric, fuzzy-based index for the evaluation of environmental quality for Mediterranean transitional waters, was calculated using biotic data gathered between 2000 and 2006 at 15 stations in 4 Tyrrhenian transitional water ecosystems (Orbetello Lagoon, Padrongiano Delta, Stagno di S. Teodoro, and Stagno di Tortolì), i.e. in a different biogeographic sub-province respect to the one in which the index was developed and validated. The rationale of FINE is that certain attributes, selected on the basis of established principles of benthic ecology, are fundamental for lagoon ecosystem function. A set of other indices (Simpson's 1-lambda', the W-statistics, AMBI, and BOPA) was also calculated and compared to FINE outputs. FINE, 1-lambda', and the W-statistics were significantly correlated with sedimentary organic matter content. Some stations were unequivocally assigned to the same ecological status, independently from the index used; for others, some discrepancies were evident. Mediterranean transitional waters probably share ecosystem complexities which are not yet fully captured by indices developed and validated elsewhere.
新的FINE指数是一种基于多指标、模糊算法的地中海过渡水域环境质量评估指数,它是利用2000年至2006年间在第勒尼安海4个过渡水生态系统(奥尔贝泰洛泻湖、帕德龙贾诺三角洲、圣特奥多罗湖和托尔托利湖)的15个站点收集的生物数据计算得出的,也就是说,该指数是在一个与指数开发和验证所在生物地理子区域不同的区域计算得出的。FINE指数的基本原理是,根据底栖生态学既定原则选择的某些属性对泻湖生态系统功能至关重要。还计算了一组其他指数(辛普森多样性指数的1-λ'、W统计量、AMBI和BOPA)并与FINE指数的输出结果进行了比较。FINE指数、1-λ'和W统计量与沉积有机物含量显著相关。一些站点被明确归为相同的生态状态,与所使用的指数无关;而对于其他站点,明显存在一些差异。地中海过渡水域可能具有一些生态系统复杂性,而其他地方开发和验证的指数尚未完全捕捉到这些复杂性。
