在全球气候变化和城市化对森林生态系统构成的复杂挑战中，将城市化控制措施纳入一个以气候为重点的框架可能会提供一个取得突破的途径。本研究深入探讨了气候，特别是水热条件的影响，在中国黄河流域（YRB）的城市化（Urb）和森林生态功能（Eco）之间的复杂的相互作用。我们的研究结果显示：（1）耦合协调模型的应用揭示了长江中下游暖湿地区城市化与森林生态功能之间存在较强的协调性。(2)通过横截面阈值回归模型，我们阐明了不同的气候梯度的城市对生态的不同反应。其中，年降水量在532.34 mm和694.18 mm处表现出双阈值效应，随着降水量的增加，城市化对生态环境的影响由负向正转变。在降水量小于532.34 mm和大于694.18 mm的地区，生态系统对城市化的响应系数绝对值增大。年平均气温在10.11 °C处表现出单阈值效应，导致随着温度的升高从负面影响转变为正面影响。本研究建立了基于气候的阈值系统，管理城市化-森林生态功能的关系。
Amidst the compounded challenges posed by global climate change and urbanization on forest ecosystems, the integration of urbanization control measures within a climate-focused framework may offer an avenue for breakthroughs. This study delves into the impact of climate, specifically hydrothermal conditions, on the complex interplay between urbanization (Urb) and forest ecological function (Eco) in the Yellow River Basin (YRB) in China. Our findings reveal: (1) The application of a coupled coordination model reveals a stronger alignment between urbanization and forest ecological function in the warm and humid regions in the YRB. (2) Through the cross-sectional threshold regression model, we elucidate the diverse responses of Urb to Eco across varying climate gradients. Among them, annual precipitation shows a double-threshold effect at 532.34 mm and 694.18 mm. As precipitation increases, the impact of Urb shifts from negative to positive on Eco. Moreover, in regions with precipitation below 532.34 mm and above 694.18 mm, the absolute value of response coefficients of Eco to Urb is amplified. Annual average temperature displays a single-threshold effect at 10.11 °C, leading to a transition from negative to positive impact as temperature rises. This study establishes the climate-based threshold system that governs the urbanization–forest ecological function relationship.
