Towards Sustainable Management of Urban Ecological Space: A Zoning Approach Hybridized by Ecosystem Service Value and Ecological Risk Assessment

Massive growth is posing threat to the ecological security and sustainability of cities. Ecosystem service value (ESV) risk index (ERI) assessment can be conducted enhance urban ecosystem management through enhanced recognition these values risks in decision-making. This paper aimed measure spatiotemporal ESV ERI for Shizuishan City located central China, and, based on this, how zone space using land cover data (for years 2010, 2015, 2020). The options different zones were suggested mitigate manage any potential negative impacts security. Results show that: (1) spatial distribution characteristic “high south low north”. total exhibited an upward tendency from 2010 2020. (2) high-ERI areas distributed peripheral region, while low-ERI concentrated region. water was decline continuously, whereas wetland maintained a high level. (3) zoning approach integrating truly reflect status environment better clarify direction development areas. Among four zones, high-ESV (I) have abundant resources, they are set as “Priority Development Areas”. low-ESV (II) “Ecological Improvement Areas” because area lands confined. (III) fragile environment, “Exploitation-Prohibited (IV) mainly near wetland, “Research-focused
