“…This paper analyzed the UER-CDB in different development directions in Beijing using the transect gradient method, and showed that the UER-CDB varies significantly in different development directions and that the "source" and "sink" resiliencies do not strictly follow the urban gradient pattern in some directions. Qiu et al [70] analyzed the landscape pattern changes in eight directions in Beijing using the transect gradient method, and found that each landscape pattern index did not change in different directions according to the urban gradient pattern, but fluctuated, and pointed out that this phenomenon was related to the transect step size, and the shorter the transect step size the greater the fluctuation. After several experiments, we found that the fluctuations in the "source" and "sink" ductility curves stabilize in most directions for a transect step size of 5 km.…”

A reasonable assessment of urban ecological resilience (UER), as well as quantitative identification of critical thresholds of UER, is an important theoretical basis for the formulation of scientific urban development planning. The existing UER assessment methods ignore the dynamic relationship between protection factors and disturbance factors in urban systems and do not address the question of where UER starts to become unstable. Therefore, based on the “source-sink” landscape theory, we constructed a UER assessment model and a method to quantitatively identify the UER’s critical distance belt (UER-CDB) using the transect gradient analysis. Additionally, we combined scenario simulation to analyze the change characteristics of UER and its critical distance belt in different urban development directions over past and future periods. The results show that: (1) Based on the “source-sink” theory and transect gradient method, the UER can be effectively assessed and the UER-CDB can be quantitatively identified. (2) The UER in Beijing shows a distribution pattern of high in the northwest and low in the southeast, and the High resilience area accounts for more than 40%. (3) The changes in UER-CDB in Beijing in different development directions have obvious variability, which is mainly influenced by topography and policy planning. (4) Compared with the natural development scenario (NDS), the ecological protection scenario (EPS) is more consistent with Beijing’s future urban development plan and more conducive to achieving sustainable development. The methodology of this paper provides a fresh perspective for the study of urban ecological resilience and the critical threshold of ecosystems.

“…The increase in urban landscape fragmentation has a significant negative effect on urbanization economic output. Most of the existing studies focus on the impact of economic development level on urban landscape fragmentation (Su et al, 2007;Qiu et al, 2012;, and are less concerned with the impact of urban landscape fragmentation on urban economic development. Local governments in China have relied on land sales to support public finance, resulting in excessive land urbanization (Li et al, 2014;, with built-up areas sprawling outward causing high levels of landscape fragmentation (Qiu et al, 2012;Wang et al, 2018).…”

This study analyzes cities in China at the prefecture level and above to calculate indices for "urban economic efficiency" (the relationship between input factors and output) and "urbanization economic efficiency" (the relationship between newly increased output and increased economic input), based on the Stochastic Frontier Analysis (SFA) method. We compare and analyze the factors influencing change and their spatial distributions. The results show that capital and labor rather than urban land could effectively improve urban and urbanization economic efficiency. And, although the proportion of wages to GDP has a significant negative impact on urban economic efficiency, for social equity and stability, the proportion should be increased; if appropriate, it would not significantly reduce urbanization economic efficiency. Additionally, population density, population urbanization rate, and government fiscal expenditure significantly positively impact urban and urbanization economic efficiency. However, we also found that increases in the degree of industrial structure deviation and urban landscape fragmentation are harmful to urbanization economic efficiency. In terms of spatial distribution, the urbanization economic efficiency of most of China's northeastern and eastern coastal areas is significantly lower than that of other regions; at the same time, the urban economic efficiency of most of these cities has been decreasing, especially in the northeast, which warrants greater policy attention.
