摘要

城市蓝绿空间景观生态是支撑城市景观生态系统的重要组成部分。本研究采用灰色系统理论(GST)、层次分析法(AHP)和理想解相似度排序技术(TOPSIS)相结合的模型,从绿地植被覆盖率、生态系统多样性、空气和水质量、社会参与度和健康度四个方面构建标准层。采用 GST 方法筛选评价指标,采用 AHP 方法计算各指标权重,最后采用 TOPSIS 方法进行加权排序,以验证评价体系的科学性和合理性。结果表明(1) 在 36 个指标因子中,有 10 个未通过 GST 法筛选;(2) 标准层的权重排序由高到低如下:D2 生态系统多样性 0.4816 > D1 绿地植被覆盖率 0.2608 > D3 空气和水质 0.1864 > D4 社会参与和健康 0.0713;(3) 济南市不同区域的相对亲近程度和排名如下:大明湖地区>山大路地区>古城地区>商埠地区。本研究有助于避免主观因素造成的决策失误,为城市蓝绿空间景观生态健康评价提供新的方法。

Assessment of Urban Blue-Green Space Landscape Ecological Health Based on the GST-AHP-TOPSIS Composite Model

The urban blue-green space landscape ecology is an important component that supports the urban landscape ecosystem. In this study, a combination model of the grey system theory (GST), analytic hierarchy process (AHP), and technique for order of preference by similarity to ideal solution (TOPSIS) was used to construct criteria layers from the following four aspects: green space vegetation coverage, ecosystem diversity, air and water quality, social participation, and health. The GST method was employed to screen evaluation indicators, the AHP method was used to calculate the weight of each indicator, and finally, TOPSIS was applied for weighted ranking to verify the scientific and rationality of the evaluation system. The results indicated the following: (1) out of 36 indicator factors, 10 were not selected through the GST method; (2) the weight ranking of the criteria layer was as follows, from highest to lowest: D2 ecosystem diversity 0.4816 > D1 green space vegetation coverage 0.2608 > D3 air and water quality 0.1864 > D4 social participation and health 0.0713; and (3) the relative closeness and ranking of different regions in Jinan city were as follows: Da Ming Hu area > Shan Da Lu area > Gu Cheng area > Shang Bu area. This study can help avoid decision-making errors caused by subjective factors and provide new approaches for the assessment of the ecological health of urban blue-green space landscapes.
