Construction of green infrastructure in coal-resource based city： a case study in Xuzhou urban area

引用

International Journal of Coal Science & Technology 2018年第1期5卷 92-104页

作者： Jiang Chang Tinghao Hu Xiangxu Liu Xiaogeng Ren School of Architecture and Design China University of Mining and Technology Xuzhou China School of Mechanics and Civil Engineering China University of Mining and Technology Xuzhou China School of Architecture Southeast University Nanjing China

As an important coal-resource based city in eastern China, coal mining activities have greatly promoted economic development to Xuzhou while resulted in kinds of blocks for sustainable development. Subsidence areas caused by coal mining activities and rapid urbanization process led to the losing of ecological function and decreasing of landscape connectivity in the city. As the important life-support system, urban green infrastructure (GI as short) has great significance in improving human well-beings. Taking Xuzhou urban area as the study object, this paper proposed a green infrastructure construction method based on the principle of ecological priority. Firstly, key ecological patches were identified by GIS and RS methods. Secondly, we established corridors by minimum cost path model. Then, we built GI network and evaluated the ecological importance of different patches. Finally, by comparing the status of patches and coal mining subsidence areas, we proposed a framework for constructing GI network in Xuzhou urban area.

Hallmark of a Resilient City: Adoption of green infrastructure in African Cities

引用

Open Journal of Forestry 2021年第1期11卷 61-72页

作者： Elias K. Maranga Department of Natural Resources and Dean Faculty of Environment and Resources Development Egerton University Njoro Nakuru Kenya

Dynamic urbanization of African cities has created development trajectories that face systemic challenges in the provision of sustainable and ecologically resilient urban environments. The specific challenges include extensive unregulated growth with informal settlements reflecting poor service levels and high poverty indices, inadequacy in provision of basic services in health, water, housing, transport and communication infrastructure, high reliance on biomass fuels, exposure to environmental stress and implausible climate change coping and mitigation mechanisms among others. Review of extensive literature and synthesis of existing bodies of knowledge on the ecological and management perspectives of urban environments revealed many gaps and understanding of urban transformation processes. The purpose of this review was to contextualize credible pathways for optimization of both ecosystem goods and services from green urban landscapes (Green infrastructure) and non-green infrastructure to ensure sustainable and ecologically resilient urban environments. Attempts were made to rationalize and validate through discussions the benefits of managed urban ecosystems for African cities. On the basis of the evidence from the literature, it is concluded that urban development trajectories that do not embrace multifaceted approaches that deliberately retain and maintain green infrastructure in the urban environment may not be cost-effective. It is recommended that systematic i

作者： WU Xiaomin Faculty of Architectural Engineering Yunnan Agricultural University

Currently, urban green Space Systems in China show fragile ecological conditions, the overseas green infrastructure is a new idea to construct urban green ecological spaces. Typical green infrastructure construction cases in the U. K., such as London greenbelt, park system, green corridor, green chain and green Grid were studied to analyze problems of China urban green Space System planning, construction, and management, so as to propose suggestions for improving ecological functions of the urban green Space System.
