Linking endangered species protection to construct and optimize ecological security patterns in the National ecological Civilization construction Demonstration Zone: A case study of Yichang, China

Ecological Indicators, Journal Year: 2024, Volume and Issue: 158, P. 111579 - 111579

Published: Jan. 1, 2024

Constructing an ecological security pattern (ESP) is effective measure to ensure environmental safety and urban development. With the establishment of national civilization construction demonstration zone in China, higher requirements are put forward for biodiversity conservation. Previous studies have focused on identification ESPs, while few optimized ESPs based endangered species protection. This study took Yichang as research object, used geospatial data construct optimize ESPs. We identified sources through sensitivity assessment extracted corridors minimum cumulative resistance model. On this basis, innovatively introduced information, ESP discussed function zones order play a greater role The results showed that: (1) includes 12 with total area 2,186.34 km2, 30 length 1120.44 km 15 nodes. (2) optimization connects important nature reserves scenic tourist areas, bringing into corridor network. importance evaluation delineated 8 Level I focusing biological protection 22 II landscape construction. (3) divided conservation zone, control restoration spatial principles each clearly defined. can provide reference species-rich cities.

Construction of an Ecological Security Pattern in Rapidly Urbanizing Areas Based on Ecosystem Sustainability, Stability, and Integrity

Remote Sensing, Journal Year: 2023, Volume and Issue: 15(24), P. 5728 - 5728

Published: Dec. 14, 2023

The escalating pace of urbanization and human activities presents formidable challenges to landuse patterns ecological environments. Achieving a harmonious coexistence between humans nature high quality has emerged as global imperative. Constructing an security pattern become essential approach mitigating the adverse impacts urban sprawl, safeguarding well-being, promoting healthy development ecosystems. Focusing on ecosystem sustainability, stability, integrity, this study constructed in rapidly urbanizing areas, emphasizing achieving well-balanced integration expansion preservation. Ecological sources were identified by evaluation system “ecosystem service function–ecological sensitivity–landscape connectivity”. Resistance surfaces integrating natural factors. corridors nodes extracted methods such minimum cumulative resistance gravity models. Taking Nanchang City example, results show that there 15 sources, primarily woodland, displaying distinct “island” phenomenon. Additionally, 41 with combined length 2170.54 km, exhibiting dense distribution southwest sparse northeast. city was found encompass 122 nodes, predominantly situated along near indicating strong spatial aggregation pattern. An optimized “one ring, two belts, three zones, multiple nodes” proposed for synergizing protection, restoration, rapid urbanizing.

Influence of Climate and Hydrological Factors on the Phenological Characteristics of Populus Euphratica in the Oasis of the Central Taklamakan Desert

Published: Jan. 1, 2025

The phenological characteristics of plants can reflect both their responses to environmental changes as well an ecosystem's sensitivity climate change. Although there have been several studies plant species worldwide, is minimal research on the phenology vegetation found in extremely arid environments within context To address this gap, study investigated effects climate-hydrological factors, including temperature, precipitation, surface and humidity, (start growing season [SOS] end [EOS]) Populus euphratica Tarim Desert Oasis. Using Landsat 7/8 satellite imagery field data, we analyzed spatial temporal variations SOS EOS from 2004 2023. availability water, particularly groundwater depth directly determined distribution P. impact increasing temperatures varied under different moisture conditions;: high-moisture environments, increased promoted earlier delayed EOS, with opposite conditions occurring low-moisture environments. highlights profound influence change, especially extreme regions. accurately predict response future ecological models should incorporate hydrological soil moisture, cold dry These findings provide important insights for developing effective protection management strategies.

Measuring coordination between land ecological security and high-quality economic development: a case of the Beijing-Tianjin-Hebei region

Frontiers in Environmental Science, Journal Year: 2025, Volume and Issue: 13

Published: Feb. 5, 2025

The interplay between land ecological security (LES) and high-quality economic development (HED) is intricately linked to the sustainable of regions, with their combined influence at county level being pivotal for harmonious growth urban agglomerations. In this study, we employ entropy-weighted technique order preference by similarity ideal solution (EW-TOPSIS), coupling coordination degree (CCD), deviation degree, relative methodologies assess developmental status LES HED, as well these two systems, introduce a novel approach delineating functional regions. Our findings reveal pronounced polarization HED within Beijing-Tianjin-Hebei (BTH) region, majority areas exhibiting high but moderate imbalance. Spatial analysis highlights distinct characteristics, allowing segmentation region into seven zones. Recommendations include establishment collaborative framework BTH enhancing innovation, openness, focusing on advancement in leading, key, stable areas. Furthermore, it essential elevate visibility responsiveness LES, strategically implement engineering key These strategic initiatives aim improve standards thereby synergy systems.
