Land use and cover changes have substantially altered surface landscape patterns, resulting in ecological risk (LER) jeopardizing the continued supply of ecosystem services (ES). Although ES LER are positive negative aspects security representation, respectively, spatiotemporal mechanism their interaction still needs to be further clarified. This study focused on Wuling Mountain Area (WMA), a critical functional zone. First, multi-source data multi-models were used evaluate analyze characteristics. Subsequently, geographically temporally weighted regression model was applied uncover heterogeneity impacts various ES. Finally, zones delineated based LER-ES quadrant, driving force analysis conducted, management strategies proposed. The main results as follows: (1) showed overall decreasing increasing trends, respectively. (2) Except for water yield, impact clear non-stationarity, with significant impact, which most pronounced habitat quality. (3) WMA divided into four zones: prevention zone, conservation enhancement reshaping Elevation, normalized difference vegetation index, human footprint identified drivers zoning. research lays solid foundation in-depth understanding proposed zoning scheme provides strong support ecologically sustainable development WMA.

Rapid developments associated with large-scale transport infrastructure have exacerbated ecological risks, posing major threats to biodiversity and ecosystem services. Construction of security patterns (ESPs) can effectively mitigate this threat, but existing construction ESPs lacks consideration the risk landscape connectivity resilience, as well zoning optimization at a finer resolution. This study focused on region along China-Laos Railway evaluate (LER) based potential-connectedness-resilience framework extracted ESP elements according LER evaluation. Clustering quality index was introduced facilitate more targeted management ESP. We found that regional most likely elevated because proportion medium level above close 50 %. Moreover, segmentation penetration high-risk areas into low-risk prominent. The distribution low notably shaped by while road expansion would create many higher areas, development industrial parks generate high risks in urban peripheries. 2,615.88 km corridors enabled 17,362.08 km2 sources be connected. 33 nodes 115 stepping stones were valid complements key weak connectivity. Priority treatment specific (4.88 %) (29.93 enhances resilience Our provides method for integrating assessment arising from future ESPs, which promoted conservation planning developing countries driven parks.

Published: March 28, 2024

In China’s pursuit of modernization, the government has introduced rural revitalization strategy to combat decline, foster balanced urban–rural development, and reduce gap. Rural human settlements, as key components this strategy, play a vital role. This paper examines types characteristics human–earth relationships within emphasizing their significance. Using national land use population census data, we analyze spatiotemporal evolution settlements at county level, investigating landscape pattern changes, assessing degree coupling coordination between categorizing relationship features, estimating potential for remediation. Our findings reveal growing trend in scale particularly sourced from arable land, with significant expansions observed North China Plain Northeast Plain, indicating farmland reclamation village consolidation. Landscape patterns exhibit increased fragmentation, complex shapes, aggregation. We categorize utilization into two types, each four distinct features: human–land is regions characterized by either higher larger settlement areas, or lower smaller areas. Human–land trade-offs are evident areas where there provides valuable insights Chinese government’s context-specific implementation strategy. It also serves an experiential reference governance other developing countries.
