Policy-Driven Scenarios for Sustainable Peri-Urban Land Use: Production–Living–Ecological Space in Yubei District, Chongqing

Land, Journal Year: 2025, Volume and Issue: 14(5), P. 1074 - 1074

Sustainable land-use planning in peri-urban areas relies on informed decision-making guided by the examination of various development strategies. This study demonstrates a policy-based multi-scenario simulation which can serve as an aid to decision-making. Using transformation production–living–ecological (PLE) spaces Yubei District, district Chongqing (2005 2020), baseline, projections, simulated for 2035 under four scenarios, highlight impacts varying policies: reference scenario (RS), allowing unrestricted transformations, risks agricultural productivity and ecological integrity; economic (S1) reveals costs associated with economics-driven urban expansion; contrast, green (S2) land protection (S3) scenarios prioritize balanced growth agricultural-land preservation so that resilience food security be effectively maintained. Overall, significant changes may occur, characterized substantial increase living space, decrease production stable areas. scenario-based analysis provides comprehensive overview potential policy-driven outcomes. aids identification policy options would best harmonize ecological, economic, social objectives, offering essential insights sustainable urbanization management developing such District.

Evolution of the ecological security pattern of the Yellow River Basin based on ecosystem services: a case study of the Shanxi section, China

Frontiers in Environmental Science, Journal Year: 2024, Volume and Issue: 12

Identifying and evaluating the ecological security pattern (ESP) of region can provide a solid foundation for optimizing regional ecosystem elements improving security. The PLUS model, InVEST circuit theory were used to analyze services ESP Shanxi section Yellow River Basin (SYRB) between 2005 2035. findings revealed that 1) total area land use shift across categories 2020 was 6,080.99 km 2 , or 5.22% SYRB’s area. Under natural development scenario, transfer from 2035 predicted be 4,605.10 . Among these, tendency construction forest expanding, while cultivated land, grassland, water area, unused shrinking; 2) From 2035, yield soil conservation all decreased, habitat quality carbon storage showed declining tendency; 3) source increased 35,767.00 in 39,931.00 2035; length corridors expanded 2,792.24 3,553.18 pinch points 27 40 barrier 21 28 which show remained unstable; 4) According service characteristics SYRB 2020, an “one axis, two zones, four corridors, multiple points” constructed. This study could useful guidance spatial maintaining services.
