Overview

Case study demonstrates spatial mismatches of ecosystem services in urban areas, highlighting ecological planning needs.

Key Points

  • The central aim is to assess ecosystem services and their spatial distribution in the Guangdong-Hong Kong-Macao Greater Bay Area.
  • Developed a dynamic assessment framework for ecosystem services from 2000 to 2015.
  • Utilized Getis-Ord Gi* spatial statistic to identify ecosystem services hotspots and coldspots.
  • Mapped five key ecosystem services: water conservation, soil retention, stormwater regulation, grain production, and carbon sequestration.
  • Delineated functional zones based on service importance.
  • Identified a spatial mismatch between ecosystem service supply and administrative boundaries.
  • Found high-value ecosystem service clusters in northern and peripheral regions.
  • Central urban basin exhibited low ecosystem service values.
  • Highlighted multi-service co-protection zones in Zhaoqing and eastern Huizhou for ecological protection redlines.
