生态区域养分标准被广泛使用，但其有效性很少得到验证，与特定地点的标准竞争。在这项研究中，我们介绍了生态谬误，这描述了现象，特定地点的压力-反应关系不能从生态区域的关系，反之亦然，探索养分标准的空间尺度。利用全国范围内的湖泊和水库的长期水质数据，确定是否存在生态谬误。分别采用贝叶斯线性模型和层次模型建立了生态区域和特定地点营养盐与叶绿素a的关系。通过比较生态区域和特定地点的关系，我们发现，生态谬误存在于每个生态区域。生态区域关系可能会误判限制养分或误判养分效应的方向和大小。我们发现，从区域和特定地点的关系条件下的平均TN或TP浓度推断出的估计Chlorophyllaconcentrations之间存在巨大差异。基于这些结果，我们确定湖泊营养标准应该是特定地点的，主要是为了避免生态谬误，而不是提高其准确性。这些发现可以指导未来营养标准的制定。我们进一步建议部分汇集数据，以发展面对密集的环境和生态数据的压力源-反应关系。
Ecoregional nutrient criteria are widely used but their validity has rarely been verified competed with site-specific criteria. In this study, we introduced ecological fallacy, which describes phenomenon that site-specific stressor-response relationships cannot be deducted from ecoregional relationship and vice versa, to explore the spatial scale of nutrient criteria. A long-term and nationwide water quality dataset of lakes and reservoirs was used to determine if ecological fallacy existed or not. Ecoregional and site-specific nutrient-Chlorophyllarelationships were built employing Bayesian linear model and hierarchical model, respectively. By comparing ecoregional and site-specific relationships, we found that ecological fallacy existed in each ecoregion. Ecoregional relationship may misidentify limiting nutrient or miscalculate the nutrient effect direction or magnitude. We found huge differences between estimated Chlorophyllaconcentrations deduced from regional and site-specific relationships conditioning average TN or TP concentrations. Based on these results, we determined that lake nutrient criteria should be site-specific, primarily to avoid ecological fallacy rather than to improve their accuracy. These findings could guide the future nutrient criteria development. We further recommended partial pooling of data to develop stressor-response relationship facing with intensive environmental and ecological data.
