Guirang Zhang, the founder and CEO of Henan Shunxiang Construction, is at the forefront of transforming urban landscapes through the innovative concept of sponge cities. With nearly three decades of career, Zhang has moved from traditional construction to championing urban designs that integrate with natural water cycles. His work addresses the dual challenges of urbanization and climate resilience.
Zhang’s approach is rooted in his belief that sustainable urban environments can coexist with nature. “Cities need to be designed with the ability to absorb, store, and reuse rainwater, much like a sponge,” Zhang says.
This philosophy has guided his projects, turning urban areas into models of sustainability and resilience. His work involves using permeable materials and creating green spaces that enhance biodiversity while managing rainwater efficiently.
Transformative Projects and Technologies
Under the leadership of Guirang Zhang, Henan Shunxiang Construction has championed significant projects that are exemplary of the six sponge city principles—Absorption, Retention, Storage, Purification, Use, and Drainage. These principles have been meticulously applied to transform urban landscapes into sustainable and resilient environments.
The Nanyang Twelve Li River Restoration project, completed between 2017 and 2020, stands as a prime example of these principles in action. This project not only employed eco-friendly techniques for river restoration, such as slope protection to prevent erosion, but also advanced the principles of Absorption and Purification by developing integrated water management systems. These systems combine pollution interception with ecological wetlands, enhancing the river’s natural ability to cleanse water and support biodiversity. Zhang’s team created permeable landscapes along the riverbanks, enhancing rainwater absorption and reducing runoff—key Retention principle aspects.
Another landmark project, the Nanyang World Rosa Chinensis Garden, showcases sponge city design’s Storage, Use, and Drainage principles. Zhang’s team implemented advanced rainwater harvesting and storage systems, ensuring that water collected during rainfalls is used efficiently throughout the garden. As Zhang notes, “Our design for the Nanyang Rose Garden was not only about beautification but making the garden a self-sustaining ecosystem.” This approach mitigates flood risks and supports the garden’s irrigation needs, enhancing the urban heat island mitigation—improving air quality and urban aesthetics.
Under Zhang’s guidance, each project adheres to the specific technical aspects of sponge city development and contributes to a broader vision for sustainable urban living spaces that effectively integrate natural water cycles into their design. These initiatives exemplify how urban areas can function like natural landscapes, which absorb, filter, store, and reuse water, all while providing aesthetic and ecological benefits to the community.
Economic and Social Impact
Zhang’s projects have significant economic benefits. The Nanyang World Rosa Chinensis Garden, for example, attracted over 5.66 million visitors in May 2019 alone, generating substantial economic activity and boosting local tourism. Zhang’s projects have also shown that sustainable practices can lead to profitable outcomes, a vital consideration for cities looking to invest in green infrastructure.
Moreover, Zhang’s initiatives have created numerous jobs and contributed to local economies, demonstrating that environmental projects can be economically viable. “These projects present environmental benefits while also providing economic opportunities and enhancing urban residents’ quality of life,” Zhang asserts.
Global Outreach and Future Aspirations
Recognizing the global relevance of his work, Zhang is keen to expand his innovative approaches beyond China. His techniques are applicable worldwide, especially in regions like Australia, where urban water management is crucial due to frequent droughts and floods. Zhang’s experience with sponge cities offers valuable lessons in enhancing urban resilience and sustainability.
The principles of sponge city technology can transform urban planning globally. Zhang is actively involved in international forums and collaborations to promote the adoption of these practices. “Sharing knowledge and experiences across borders is key to developing cities that are not only livable but also resilient to environmental challenges,” Zhang says.
Continuing Innovation and Education
Zhang’s focus on innovation and education matches his devotion to sustainability. His company invests in research and development to refine existing technologies and discover new ones. He also emphasizes the importance of education and training for his staff, ensuring they are well-equipped to implement complex ecological projects.
As cities grow, Zhang’s insights and methodologies will likely play an increasingly important role in urban development. His dedication to integrating ecological balance with urban growth has set a benchmark in the construction industry, proving that sustainable development can be practical, beneficial, and revolutionary.
