Research Progress of China's Urban Growth Boundary from Perspective of Ecological Security Pattern

【Purpose】China’s new urbanization continues to accelerate and the land resources oc?cupied by cities are expanding rapidly.The problems such as the destruction of the structure and function of the ecosystem and the disorderly expansion of cities arise in the traditional extensive urban growth pro?cess.Reasonably controlling the scale of cities and optimizing the urban ecological security pattern have become one of the key tasks of land and resources management in China.【Method】Through the literature research method and the inductive deduction method,the current urban spatial growth boundary is optimized and regulated from the perspective of maintaining urban ecological security.【Result】Under the background of China's large-scale urbanization,the implementation of urban growth control policies is an inevitable choice.The urban growth boundary has diversified connotations and is an important con?trol method for regulating land resources in the context of urban expansion.It is of great significance to improve urban spatial governance,protect urban ecological security and promote urban sustainable devel?opment.China has achieved certain results in the delineation of urban growth boundaries.The academic community has formed different delineation technical paths based on different value orientations.When delimiting urban growth boundaries,the complex attributes of cities should be taken into consideration and the law of urban growth in China should be discussed in depth.The direct contradiction between the ecological security pattern and urban growth under the delineation of urban boundaries should be coordi?nated with diversified means.【Conclusion】The urban growth boundary is the dynamic expansion bound?ary line of urban land defined under different development backgrounds.The urban land expansion boundary in different periods is adjusted according to economic,social,natural and other factors.The“flexible”and“rigid”growth boundaries delineate the adjustable area and permanently prohibited strate?gic development space.Adhering to the ecological priority thinking,coordinated with differentiated con?trol,boundary adjustment and other supporting measures,it guides a new urban growth model oriented by ecological security pattern.
