碳中和背景下的棕地滨水景观设计——以成都绣川河为例
Landscape Design of Brownfield Waterfront under the Background of Carbon Neutrality—A Case Study of Xiuchuan River in Chengdu

在全球气候变化和碳中和目标的大背景下，棕地(即废弃或受污染的土地)的再生利用与滨水景观的绿色设计成为城市可持续发展的重要方向。本文以成都市的绣川河为例，深入探讨了碳中和理念在棕地滨水景观设计中的应用与实践。首先，分析了绣川河棕地的现状特征，包括其历史背景、环境污染状况以及土地利用潜力。在此基础上，提出了基于碳中和原则的棕地再生策略，旨在通过生态修复、绿色能源利用和低碳材料应用等手段，实现棕地环境的整体改善。接着，详细阐述了绣川河滨水景观设计的具体方案。该方案注重保留场地的自然生态特征，通过恢复水生植物群落和设置生态驳岸等措施，增强滨水区域的生物多样性和生态服务功能。最后，该设计不仅有效改善了棕地的生态环境质量，还显著降低了区域的碳排放强度，为实现碳中和目标做出了积极贡献。本文的研究为其他类似棕地的再生利用和滨水景观设计提供了有益的参考和借鉴。
In the context of global climate change and carbon neutrality goals, the regeneration and utilization of brownfields (i.e. abandoned or polluted land) and the green design of waterfront landscapes have become important directions for urban sustainable development. This article takes the Xiuchuan River in Chengdu as an example to deeply explore the application and practice of carbon neutrality concept in brownfield waterfront landscape design. Firstly, the current characteristics of the Xiuchuan River brownfield were analyzed, including its historical background, environmental pollution status, and land use potential. On this basis, a brownfield regeneration strategy based on carbon neutrality principles was proposed, aiming to achieve overall improvement of brownfield environment through ecological restoration, green energy utilization, and low-carbon material application. Then, the specific plan for the landscape design of Xiuchuan Riverside was elaborated in detail. This plan focuses on preserving the natural ecological characteristics of the site, enhancing the biodiversity and ecological service functions of the waterfront area through measures such as restoring aquatic plant communities and setting up ecological embankments. Finally, this design not only effectively improves the ecological environment quality of brownfield, but also significantly reduces the carbon emission intensity of the region, making a positive contribution to achieving carbon neutrality goals. This study provides useful reference and inspiration for the regeneration and utilization of similar brownfields and waterfront landscape design.
