城市绿地生态技术适宜性评估与集成应用

The Suitability Evaluation and Integrated Application of Ecological Technology in Urban Green Space

随着中国城镇化的快速发展,原有场地及周边区域的固有特征被改变,土地利用方式的转变直接影响了区域环境和生态系统,城镇化过程导致"城市病"问题的出现。如何运用城市绿地生态技术提高城市环境和生态服务功能,逐渐成了风景园林学科的研究热点。从城市绿地生态技术需求的问题导向分析入手,初步确立涉及景观生态空间结构、植物与群落配置、土壤资源保护与利用、水域空间与暴雨径流、废弃物循环利用与填埋场绿化四大类26个问题,形成了保护、修复改善和资源利用3个层次的场地背景本底要素调查和技术要求,在综合权衡城市绿地生态技术优选原则的基础上,建立包含八大类50项的城市绿地生态技术分类技术库,总结提出了城市绿地生态技术集成的六大原则和应用优化基本流程,为城市绿地生态技术应用提供借鉴。

As urbanization has developed rapidly in China, the inherent characteristics of the original land and the surrounding areas havebeen altered. This transition in land use has caused a number of changes directly to the local environment and has had significant implicationsto the local ecosystems. These impacts that relate to environmental quality are seriously polluted by urban development. Urban green spaceplays an important role in improving urban living environment and maintaining ecological balance. Currently, the studies of using ecologicaltechnologies in urban green space, focused on improving the quality of urban environment and service, is gradually becoming the hotspotin landscape architecture discipline. Firstly, this paper used the problem-oriented analysis of increasing demands for ecological technologyin urban green space. Preliminary investigations established 4 categories of 26 questions, which involved the spatial structure of landscapeeco systems, plant community arrangement, protection and rational using of soil resource, aquatic ecosystem health and solid waste circularutilization. Secondly, 3 levels of background elements investigation and technical requirements are established, including ecological spaceprotection, restoration and improvement of resources utilization. Based on the comprehensive analysis of the application principles ofurban green space ecological technology, a database of ecological technology which contained 8 major categories of 50 technologies wasestablished, could be applied in urban green space. Finally, this article summarized and put forward 6 principles and basic process forintegrated application of ecological technology, which could provide reference for the application of ecological technology in urban greenspace.
