摘　　要：[目的]科学评价小微湿地景观美学与碳减排效益,旨在提升小微湿地综合效益。[方法]选取安徽建筑大学南校区小微湿地野外长期观测试验样地作为研究场地,于夏、秋季逐月拍摄,基于AHP、熵权的TOPSIS和雷达图法,以主观打分为美学主观评价指标,以分形与生理测量数据为美学客观评价指标,以CO_(2)和CH_(4)排放当量为碳减排指标,评价夏秋季小微湿地景观美学和碳减排综合效益,并验证不同方法的一致性。[结果]1)AHP和熵权指标权重排序均为碳减排效益>主观评价>客观生理。2)AHP和熵权两种权重结果下的TOPSIS均表明夏季美学效益高于冬季(AHP,夏季0.35>冬季0.33;熵权,夏季0.32>冬季0.28),但碳减排效益低于冬季(AHP,夏季0.15<冬季0.16;熵权,夏季0.23<冬季0.24)。3)TOPSIS两种权重与雷达图法均表明小微湿地夏季综合效益高于冬季。[结论]TOPSIS与雷达图法结果一致,可用于小微湿地综合效益评价。冬季种植常绿植物可提高景观美学价值,夏季选取高固碳植物可提高碳减排效益。夏季的碳减排效益和冬季的美学效益是未来研究设计优化的方向。[Objective]This study is to make a scientific assessment of landscape aesthetics and emission reduction benefits of micro-wetlands so as to optimize their comprehensive benefits.[Method]The field-based long-term monitoring experimental plot of micro-wetlands in the South Campus of Anhui Jianzhu University is selected to take pictures each month in summer and autumn.Both Analytic Hierarchy Process(AHP),entropy-weighted TOPSIS methods and radar chart analysis are adopted to assess the comprehensive benefits of landscape aesthetic and emission reduction benefits of micro-wetlands in summer and autumn based on the indexes consisting of the subjective aesthetic evaluation indicators based on questionnaire scores,objective aesthetic evaluation indicators derived from fractal analysis and physiological measurements,and emission reduction benefit indicators represented by CO_(2) and CH4 emission equivalents.The consistency and reliability of these methodologies are validated.[Result]1)The weight of indexes of both AHP and entropy weighting are ranked as emission reduction benefits>subjective evaluation>objective physiological measurements;2)Regardless of weighting method,the TOPSIS analysis reveals that the aesthetic benefits of micro-wetlands are higher in summer than in winter(AHP:summer 0.35>winter 0.33;entropy weighting:summer 0.32>winter 0.28),while carbon emission reduction benefits are lower in summer than in winter(AHP:summer 0.15<winter 0.16;entropy weighting:summer 0.23<winter 0.24);and 3)Both TOPSIS results under different weights and radar chart analysis consistently indicate that the comprehensive benefits of micro-wetlands are higher in summer than in winter.[Conclusion]The consistent results between TOPSIS and radar chart method demonstrate their applicability in evaluating the comprehensive benefits of micro-wetlands.Winter planting of evergreen species could enhance landscape aesthetics,while selecting the plants with high carbon storage in summer could improve carbon emission reduction benefits.Enhancin
