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, Год журнала: 2023, Номер 15(24), С. 5728 - 5728

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.

Three Decades of Oasis Transition and Its Driving Factors in Turpan–Hami Basin in Xinjiang, China: A Complex Network Approach

Remote Sensing, Год журнала: 2024, Номер 16(3), С. 465 - 465

Опубликована: Янв. 25, 2024

As a predominant ecosystem-providing area and distinctive landscape in arid regions, an oasis plays important role maintaining land stability, human production, daily activities. Studying the dynamics of its driving factors is vital to supporting regions’ sustainable development. typical mountain–desert–oasis landscape, Turpan–Hami (Tuha) Basin, located Xinjiang, China, includes complex interactions among different types. For this study, we revealed spatio-temporal patterns transition processes using network method between 1990 2020 Tuha Basin. In network, degree value, betweenness centrality, average path length were calculated express relationship, key type, structural respectively. Six related climate change actives selected investigate forces behind transitions, including temperature precipitation growing season, total power agricultural machinery (TAMP), production raw coal (PRC), output value plantation industry (TPI), population (Pop). Our results show that natural artificial oasis, all grew from 2020, with expanding more than oasis. The transitions types became frequent as increased throughout study period. Grassland acted most type highest but importance declined due increasing complexity 2020. simpler, stability decreased. Through force analysis, changes showed positive correlation (p-value < 0.05, r = 0.88), urbanization industrialization prompted built-up areas cropland grassland shrubland. summary, our suggest create harmonious symbiotic relationship environment dryland activities, preventing degradation excessive reclamation cover available way. Meanwhile, protection shrubland water resources also important. This provided reference theory support for promoting development oases.

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

Опубликована: Янв. 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, Год журнала: 2025, Номер 13

Опубликована: Фев. 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.
