摘要
欧洲标准 EN 16039:2011 为评估《水框架指令》中的湖泊水文形态提供了指南,其中包括基于应用于地形图数据的统计模型来估算水量、平均深度和最大深度的方法。我们使用独立收集的 35 个瑞典湖泊的测深数据测试了这些模型的预测准确性。这些模型没有预测能力,最大深度预测值与观测值成反比。体积和平均深度的平均绝对百分误差为 46%,最大深度为 85%。这些模型存在缺陷,不应使用。
The Methods for Estimating Lake Volume, Mean Depth, and Maximum Depth in European Standard EN 16039:2011 Are Flawed and Should Not Be Used
The European Standard EN 16039:2011 provides guidelines for assessing lake hydromorphology within the Water Framework Directive and includes methods for estimating volume, mean depth, and maximum depth based on statistical models applied to data from topographic maps. We tested the predictive accuracy of these models using independently collected bathymetric data from 35 Swedish lakes. The models had no predictive power, and the maximum depth predictions were inversely correlated with the observed values. The mean absolute percent error was 46% for volume and mean depth, and 85% for maximum depth. The models are flawed and should not be used.
期刊介绍:
Aquatic Conservation: Marine and Freshwater Ecosystems is an international journal dedicated to publishing original papers that relate specifically to freshwater, brackish or marine habitats and encouraging work that spans these ecosystems. This journal provides a forum in which all aspects of the conservation of aquatic biological resources can be presented and discussed, enabling greater cooperation and efficiency in solving problems in aquatic resource conservation.
