城市生态系统服务对于提高城市韧性、维护城市健康、保育生物多样性起决定性作用。进行生态系统服务定量评价,可以探索生态系统服务的内涵机制和影响因子,从而更好地维持和发挥生态系统服务功能,促进城市的可持续发展。本文以德国北威州盖尔森基辛市沙尔克协会(Schalker Verein)地区为例,从风景园林的视角出发重新构建了生态系统服务评价模型,引入生态系统服务评价矩阵(ES Matrix)将专家评分和城市土地覆盖/利用(LULC)变化相联系,结合德国生境制图法(Biotope Mapping),对场地进行定量化生态系统服务评价,最后以评价结果为指标通过GIS进行可视化制图,划定了城市生态系统的提供、受益、连接区域,成为了景观规划、城市土地利用开发的参考和依据。
Urban ecosystem services play a decisive role in improving urban resilience, maintaining urban health and conserving biodiversity. The quantitative evaluation of ecosystem services can explore the connotation mechanism and impact factor of ecosystem services so as to better maintain and play the ecosystem service function and promote the sustainable development of cities. Taking the Schalker Verein region of Gelsenkirchen, North Rhine-Westphalia, as an example, this paper reconstructs the ecosystem service evaluation model from the perspective of landscape architecture and introduces ESM (Ecosystem Service Evaluation Matrix) Expert scoring is linked to changes in urban land cover / utilization (LULC), combined with the German Biotope Mapping, to evaluate the quantitative ecosystem services of the site. Finally, visualization of the site is performed using GIS as the indicator of evaluation results. The provision, benefit and connecting area of urban ecosystem have become the reference and basis of landscape planning and urban land utilization development.
