Simulating macroinvertebrate responses to multiple environmental stressors is an important tool for water quality management, by predicting ecological effects of both stressors and restoration practices. Currently, existing modelling approaches fall short in simulating the responses of macroinvertebrate assemblages to environmental constraints, lacking incorporation of the multiple spatial and temporal scales on which stressors act, including their mutual interactions and uncertainties associated with input data. In answer to these shortcomings, this study aimed to design a conceptual multiscale model for simulating responses of macroinvertebrate assemblages to multiple environmental stressors. To this purpose, we drew up model requirements, selected model building blocks and assembled these into a conceptual model, also documenting the challenges that remain to be solved. This conceptual model offers a direction for simulating responses of macroinvertebrate assemblages to multiple stressors, which in turn can be used to better focus management resources and restoration practices.

通过预测应激源和恢复实践的生态影响，模拟无脊椎动物对多种环境应激源的响应是水质管理的重要工具。当前，现有的建模方法在模拟大型无脊椎动物集合对环境约束的响应方面尚不完善，缺乏整合压力源作用的多个时空尺度，包括它们之间的相互作用和与输入数据相关的不确定性。为了解决这些缺点，本研究旨在设计一个概念性的多尺度模型，以模拟大型无脊椎动物组合对多种环境胁迫的响应。为此，我们草拟了模型需求，选择了模型构建块并将其组装成概念模型，还记录了仍有待解决的挑战。该概念模型为模拟大型无脊椎动物组合对多个压力源的响应提供了方向，进而可用于更好地集中管理资源和恢复实践。
