Enhancing Ecological Network Connectivity Through Urban–Rural Gradient Zoning Optimization of Ecological Process Flow

Land, Journal Year: 2025, Volume and Issue: 14(4), P. 668 - 668

Published: March 21, 2025

Urbanization has significantly impacted ecological connectivity, making the optimization of networks (ENs) crucial. However, many existing strategies focus on overall network structure and overlook spatial concentration local processes flow (EPF), limiting effectiveness planning. This study proposes a novel EN framework based urban–rural gradient zoning to enhance connectivity from perspective EPF. The divides areas outside core urban zone (CUZ) into fringe (UFZ), interface (UIZ), natural rural (NRZ), applying tailored in each zone. These include increasing corridor redundancy, reducing resistance, expanding width alleviate EPF concentration. Using Jinan, mega-city China’s Yellow River Basin, as case study, this simulated changes over 20 years validated framework’s effectiveness. Optimization validation showed that land low-flow corridors 65% UIZ NRZ 5 km improved by 6.3%, addressing seven pinch points three barrier points. highlights importance optimizing ENs via support sustainable development protection policies.

Spatio-Temporal Dynamics and Drivers of Ecosystem Service Bundles in the Altay Region: Implications for Sustainable Land Management

Land, Journal Year: 2024, Volume and Issue: 13(6), P. 805 - 805

Published: June 6, 2024

Understanding the dynamics of ecosystem services (ESs) in arid landscapes and socio-ecological systems is crucial for sustainable development human well-being. This study uses Invest model to quantify spatio-temporal changes four key ecosystems Altay from 1990 2020: water yield (water yield), carbon stock (carbon stock), soil retention (soil retention), habitat quality (habitat quality). The trade-offs/synergies between different ESs were investigated via Spearman’s correlation analysis. Ecosystem service bundles (ESBs) mapped using self-organizing mapping (SOM), drivers ES relationships ESBs revealed through redundancy results showed that increased by 33.7% 1.2%, while decreased 3.5% 1.24%, respectively. spatial distribution pattern had a clear zonal pattern, with northern mountainous areas higher than southern desert areas. six pairs ESs, general, mainly low trade-off high synergistic relationships, trade-offs stock, quality, decreasing trend over time. Four types distinguished, compositional differences within each ESB determined interactions landscape types. There are complex non-linear years. Before 2010, ecological factors influencing ESBs, whereas social environmental combined drive allocations after 2010. Additionally, this found implementation conservation measures, such as reforestation land management practices, positively influenced provision region. These findings underscore importance integrating efforts into use planning decision-making processes ensure delivery landscapes.

Construction of a Symbiotic Traffic Network of Traditional Villages in the Western Hunan Region of China Based on Circuit Theory

Sustainability, Journal Year: 2024, Volume and Issue: 16(13), P. 5468 - 5468

Published: June 27, 2024

The concentrated and contiguous development of traditional Chinese villages is imminent, the realization their symbiotic coordinated has become both a priority challenge. Taking 370 in Western Hunan as research object, GIS spatial analysis method was used to identify extract sources Hunan, construct traffic resistance surfaces, corridors nodes based on circuit theory, optimize network Hunan. results show that composed 47 village sources, 77 corridors, 68 key nodes, which are northwest southeast showing spider-like structure. distribution shows characteristics high north low middle, surface being south. Four corridor optimization principles five node restoration strategies proposed. This study provides new concept underlying, for, planning construction transport promoting centralized protection utilization regions assisting implementation rural revitalization strategy.

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

Published: Oct. 25, 2024

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.
