Dynamic processes were monitored freely available Landsat time series. classified into five categories: forest, grassland, cropland, urban (buildings) wetland (water). Using Morphological Spatial Pattern Analysis, connectivity elements forest determined. Despite relatively high rates provision population with green infrastructure large forested area, forests have an insular (fragmentary) nature low connectivity. This does not contribute creation cohesive network ecological framework town. It established that there no significant changes town, however, some emerged, which should be taken account future planning.

Introduction Machine learning techniques, renowned for their ability to process complex datasets and uncover key ecological patterns, have become increasingly instrumental in assessing ecosystem services. Methods This study quantitatively evaluates individual services—such as water yield, carbon storage, habitat quality, soil conservation—on the Yunnan-Guizhou Plateau years 2000, 2010, 2020. A comprehensive service index is employed assess overall capacity, revealing spatiotemporal variations services exploring trade-offs synergies among them. Additionally, machine models identify drivers influencing services, informing design of future scenarios. The PLUS model used project land use changes by 2035 under three scenarios—natural development, planning-oriented, priority. Based on simulation results these scenarios, InVEST applied evaluate various Results During 2000-2020, exhibited significant fluctuations, driven synergies. Land vegetation cover were primary factors affecting with priority scenario demonstrating best performance across all Discussion research integrates model, providing more efficient data interpretation precise design, offering new insights methodologies managing optimizing Plateau.

Constructing ecological security patterns (ESPs) is the basis for achieving sustainable regional development. This study explored a framework of spatially balanced ESPs suitable rapidly urbanizing areas to address issues overreliance on land and subjective parameter settings in traditional ESP construction methods. Three ecosystem service bundles (product supply, water conservation, habitat maintenance) were identified Guangzhou using self-organizing feature map method. These then used identify multifunctional sources. The minimum size source was determined be 10 km2 through "structure-pattern-function" framework, total 19 sources from three functions extracted. In these scenarios, 102 corridors classified into five categories based their connected Ecological node parameters set local planning dominant species characteristics, enhancing explanatory power circuit theory. multi-scenario proposed this achieved distribution entire region at point, line, surface levels, as confirmed by network assessment results. Future should value non-conventional land, such cropland urban green spaces, while considering impact human activities environment promptly modifying crucial areas.
