| Study on the Evolution of Green Space in Gobi Oasis City: Taking Zhangye as an Example |

| Abstract: |
| Zhangye is located at the intersection of the ancient “Silk Road” and “Juyan
Ancient Road”. Since its establishment in the Western Han Dynasty, it has a history of
more than 2,100 years. The Heihe River system is the mother river in Zhangye City and
even the Hexi region. It nurtures large oasis and agricultural irrigation areas in the Hexi
Corridor. As a typical Gobi oasis city, Zhangye is particularly rich in water resources. It
is known as “Secret Jiangnan”, and there are beautiful landscapes of “four sides of reeds
and three sides of water, one city of willows and half city of lakes” in the Ming and Qing
dynasties. Since ancient times, the rulers of all generations have attached great importance
to water development and urban construction in Zhangye. The sensitive and unique
natural environment has always been the main factor affecting the location, evolution and
development of Zhangye City.
As the urbanization process continues to accelerate, Zhangye is currently facing problems
such as blocked rivers, shrinking water systems, and inadequate water environment ecology. In
recent years, the overall protection of the natural environment in Zhangye has been ongoing,
but its ecological historical cultural value has not been fully utilized and excavated. The thesis
is based on the research of historical data, with time as the axis, and adopts the diachronic
method to carry out specific research work to observe the development and evolution of
Zhangye’s modern urban spatial form. From phenomena to essence, we propose strategies for
protection and sustainable development in view of the current problems. Implementation has
important value and practical significance.
With the blind expansion of urban construction in modern times, the urban green
space is increasingly affected by human factors. The urban green space is attached
to the urban spatial structure to dominate the direction of urban development, from
passive to close, which shows the twists and turns of Zhangye’s ecological environment
construction, and the connotation of urban green space is more abundant. With the rapid
development of today’s society and economy, ecological safety and ecological restoration
have become issues that need to be solved urgently for the urban environmental
protection and development of Zhangye. Since the early days of the founding of
the People’s Republic of China, the urban ecological construction of Zhangye has
experienced historical twists and turns, but it has been improving. The natural landscape
pattern is the cornerstone of urban planning and development. In the course of more than a thousand years of history in Zhangye, a pattern of organic integration of mountains, water and cities has gradually formed. The
development of urban green space is based on the natural environment and is affected by many factors such as government decision-
making, urban planning, history and culture, and economic development. With the transformation of the urban development mode, it
has changed from functional to systemic, from singular to complex and diversified. Overall, urban green space patches are increasing,
and urban green coverage has increased year by year. Urban green space transitions from a “fragmented” decentralized layout to a
“systemized” centralized layout, and from the development of attachment to the urban layout to the combination of urban structure
development. From the urban development process from 1949 to 2012, it can be seen that urban green space construction is proceeding
with the direction of urban expansion. Urban green space is unevenly distributed, weakly correlated, and urban water way blockages are
more prominent.
Zhangye is an important ecological safety barrier and transportation hub in the Hexi region. The establishment of the Heihe Wetland National
Nature Reserve is an important milestone in the development of environmental protection in Zhangye, marking the transformation of the urban
water environment from the initial material needs to spiritual needs, from functional needs transforming into ecological needs. In the future, the
urban construction of Zhangye should follow the laws of urban development, coordinate the functional layout, protect the style of the ancient city,
and establish relevant local laws and regulations to promote the overall construction of the urban water environment, ensure urban ecological
safety, and maintain the characteristics of the urban water environment.
In this paper, Zhangye, the Gobi oasis city, is selected as the research object. Because of its unique natural environment, long history and
culture, and sensitive and fragile urban ecosystem, the study of urban green space is of special significance. Through four different time periods,
the characteristics of Zhangye urban green space development and analysis are analyzed, and it is concluded that the natural environment is
the foundation of green space development, the social economy is the fundamental driving force of green space development, and government
behavior and planning ideas are the main driving force of evolution of green space development. It also discusses the construction of Zhangye
ecological security barrier and the improvement of human settlement environment in the future. |
