Accurately and timely quantifying the dynamics of urban sprawl is essential for improving land use efficiency planning. However, existing research mainly focused on a single city or agglomerations in China, while national scale studies used short-term remote sensing data to quantify sprawl. Therefore, we still lack long term most up-to-date understanding especially different regions, cities sizes. Here, quantified spatiotemporal using index (USI) based latest population census, analyzed its driving force China during 2000 ~ 2020 optimal parameters-based geographical detector. The results showed that past two decades, Chinese were experiencing sprawl, with an average USI 3.04, indicating annual growth rate lands was 3.04% higher than population. Overall, slowdown, dropping from 3.55 2010 2.53 2020. Among more severe western region, where 5.33 89.3% exceeded speed. Recently, transportation substantially increased. In future, Territorial Spatial Planning should pay attention confining excessive small- medium-sized region China.

Understanding the complex interactions between urbanization and ecosystem services (ESs) is crucial for optimizing planning policies achieving sustainable urban management. While previous research has largely focused on highly urbanized areas, little attention been given to phased effect of progressive ES networks. This study proposes a conceptual framework that utilizes network method space-time replacement examine relationships among ESs at different stages, with particular emphasis evolution process. We apply this Horqin area, typical eco-fragile area in China. Results demonstrate connectivity synergy exhibits non-stationary characteristic, initially increasing, then decreasing, subsequently strengthening, while its modularity shows rising trend during periods accelerated urbanization. The performance trade-off displays opposite pattern. Additionally, we observe gradual provisioning regulation by cultural terms dominance as advances. By providing guidance identifying key initiatives implementing ecological protection stages development, contributes pathway can inform development strategies other regions undergoing

To integrate the sponge city concept into urban development, we propose an analytical approach for runoff volume control, considering expansion. Using Changchun City as a case study and historical land-use data, simulated prediction of City’s structure 2035 change with GeoSOS-FLUS platform. We calculated storage volumes Low Impact Development (LID) designs using 2019 land surface data. The objective is 80% control rate by 2035. Through Monte Carlo simulation sensitivity analysis, assessed impact various types on LID calculations. Findings show that industrial significantly influences volumes. This highlights need precise surveys properties composition in planning more accurate analysis City. results indicate based current data may not meet long-term goals due to increased impervious surfaces coefficients during urbanization.

Riyadh is the most populous city in Saudi Arabia, with a population of over five million people. The governmental and economic centers Arabia are located city. Due to fact that metropolitan region surrounds continuously growing expanding, appropriate planning essential. To be able formulate efficient plans, one needs access trustworthy facts information. Failing have clear picture future renders inefficient. Along hybrid time-series prediction expansion wider area, an urban growth forecasting model was constructed for as part this study. This used make projections about city's population. conducted application Linear Regression (LR), Seasonal Auto-Regressive Integrated Moving Average (SARIMAX), (ARIMA). dataset study consisted satellite images surrounding were acquired between 1992 2022. Mean Absolute Percentage Error (MAPE) applied measure performance proposed models. calculated MAPE vales 2.0% SARIMAX, 12% LR, 22% ARIMA.
