“…In sum, this study attempts to quantify the transition of urban land use in China using the nonlinear function fitting method. We focus on urban residential land in this study because it is a good indicator reflecting urbanization and is closely related to human habitation and life [19,20]. This paper is organized as follows.…”

“…In addition, the rapid expansion of urban land may cause a series of problems such as traffic congestion, environmental degradation, and cultivated land occupation [26,27], leading to diseconomies of scale. Nonetheless, land use efficiency can be enhanced if the potential of stock land is harnessed systematically and the growth of highly land-intensive industries is encouraged [20,28]. At this stage, the pace of land area expansion may shift from increasing to decreasing.…”

“…As a result of tighter regulation of land use and reduced population size, the size of urban residential land may settle, and its growth rate may continue to decline or even stagnate. The overall amount of urban residential land in some cities may fall at first and later remain stable if inefficient idle land is re-zoned into other land use types [20], such as ecological land. The process of urban development also reflects the process of urban land use change.…”

It is common to see urban land expansion worldwide, and its characteristics, mechanisms, and effects are widely known. As socio-economic transition and the change of land use policies may reverse the trend of urban expansion, in-depth research on the process of urban land use change is required. Through a process perspective, this paper reveals the change paths, development stages, and spatial patterns of urban residential land use with data from 323 cities in China from 2009 to 2016. The results show that: (1) theoretically, urban residential land use change can be divided into four development stages: an initial stage (Ⅰ), a rapid development stage (Ⅱ), a transition stage (Ⅲ), and a later stage of transition (Ⅳ). The rate of land use change is low—increase—decrease—approaching zero. (2) In about 68.7% of China’s cities, urban residential land is experiencing a transition, shifting from accelerating growth to decelerating growth. Given the distinctive transition process, it has been suggested that urban planning and land use policies should give timely responses to the new trends and spatial differences.

“…In China, metropolises such as Beijing, Shanghai, and Guangzhou City are beyond radical urbanization [8] and are pursuing high-quality development and smart urban growth [9]. Therefore, new urban land will become a scarce resource for urban development in the coming decades, and optimizing new urban land allocation has become a core issue for governments [10]. The allocation of new urban land has always been the focus of government and academia, particularly quota and space allocations [11].…”

Previous allocations of new urban land were ineffective because they lacked synergy between quota and space, challenging the government planning authority. This study proposes a new and more reasonable urban land allocation method to guide the smart growth of cities. We used a logistic regression model and multisource data to explore the laws of urban growth and employed a cellular automata (CA) model to simulate this under inertial and constrained scenarios. In addition, the disparities between both scenarios concerning allocation were analyzed. We realized the synergy of quota and space allocations of new urban land through urban growth simulation. Further, the allocation of new urban land was more consistent with the development strategy of Guangzhou under a constrained scenario. The allocation of space was more regular and concentrated under a constrained scenario, which aligns with the requirements of the Government Land Space Planning. Additionally, in the constrained scenario, the bottom lines of cultivated land protection, ecological service, and geological safety were better controlled. This study compensated for the shortcomings of the disjoined quota and space allocations of new urban land and proved that a constrained scenario can more effectively promote reasonable urban growth.

Geometric Accuracy Evaluation Method for Subway Stations Based on 3D Laser Scanning

et al. 2022

The rapid development of three-dimensional (3D) laser scanning technology has provided a new technical means for the geometric accuracy evaluation of subway stations. With high precision and high efficiency, laser scanning technology can present the construction site condition in a panoramic way, which is essential for achieving high precision and all-round geometric accuracy evaluation. However, when the survey coordinate system of the design building information modeling (BIM) predefined in the design stage is not applied during the laser scanning data acquisition or the BIM loses the survey coordinate system during the interaction, the objects will have different coordinate positions in the point cloud and BIM, which will limit the accuracy comparison between the two data sources. Meanwhile, the existing methods mainly focus on the above overground buildings, and the accuracy evaluation of underground structures mainly focuses on the overall deformation monitoring. So far, the existing methods do not constitute a hierarchical index system to assess the geometric accuracy of various objects in the subway station. This study proposes a method to evaluate the geometric accuracy of subway stations based on laser scanning technology. A coarse-to-fine coordinate registration from point cloud to the design BIM is used to unify coordinates in different reference systems; and geometric accuracy evaluation of different structures in subway stations is achieved by developing geometric accuracy evaluation indexes and technical systems. The method is applied to the geometric accuracy monitoring of the Hongqi Road subway station, and the experimental results verify the reliability of the method.
