This study established a multifunctional decision-making framework for evaluating the suitability of green infrastructure (GI) based on regional pollution load intensity, slope, available space, and constructible area. The framework considers the environmental and ecological functions of GI and can be extended to other cities to assess GI preference.
The effectiveness of runoff control infrastructure depends on infrastructure arrangement and the severity of the problem in the study area. Green infrastructure (GI) has been widely demonstrated as a practical approach to runoff reduction and ecological improvement. However, decision-makers usually consider the cost-efficacy of the GI layout scheme as a primary factor, leading to less consideration of GI's environmental and ecological functions. Thus, a multifunctional decision-making framework for evaluating the suitability of GI infrastructure was established. First, the study area was described by regional pollution load intensity, slope, available space, and constructible area. Then, to assess the multifunctional performance of GI, a hierarchical evaluation framework comprising three objectives, seven indices, and sixteen sub-indices was established. Weights were assigned to different indices according to stakeholders' preferences, including government managers, researchers, and residents. The proposed framework can be extended to other cities to detect GI preference.
