With the worsening of global and local environmental problems, ecological security has a vital role to play in sustainable development, become worldwide topic concern 21st century. This study used bibliometric analysis comprehensively review progress research from 2000 2020 provide an overview for future directions. We analyzed 761 publications related this period, covering 34 countries, 370 journals, 631 institutions, 585 funding agencies, 2680 authors. The results showed that majority (71.75%) appeared 2014 2020, with conducted mostly China, followed by USA Russia. top 10 active institutions were all Chinese; Chinese Academy Sciences was most productive institution, also had highest number citations. China at center international cooperation network, collaboration USA, Australia, Canada.

Evaluating the ecological security of ecotourism in protected area based on the DPSIR model

Ecological Indicators, Journal Year: 2023, Volume and Issue: 155, P. 110957 - 110957

Published: Sept. 19, 2023

Evaluating the ecological security of ecotourism (EES) in protected areas is critical because these play a vital role protecting biodiversity and natural resources. This study evaluated EES status Central Alborz Protected Area (Northern Iran), based on Driver, Pressure, State, Impact, Response (DPSIR) model. We developed comprehensive list 59 indicators for DPSIR model employed an Analytical Network Process (ANP) to determine indicator weights harnessing opinion experts which are most influential. approach facilitated identification regions with highest vulnerability, notably northern western sectors our area along boundary between Tehran Mazandaran provinces. Here, mechanisms that drive change include activities, livestock overgrazing, uncontrolled physical economic extensive road highway development, land use cover changes. Indicators effective determining status, activities. conclude by discussing respond increasing threat Areas such as involvement government strategic integrated management.

Evaluation of land ecological security and driving factors in the Lower Yellow River Flood Plain based on quality, structure and function

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 21, 2025

Land ecological security (LES) is crucial for human well-being and sustainable development, especially in areas like the Lower Yellow River Flood Plain (LYRFP), which faces flood threats, economic challenges, fragility. This study introduces a "Quality-Structure-Function" framework evaluating LYRFP's LES, incorporating baselines impacts of land use changes on comprehensive assessment. Using Optimal Parameter Geographic Detector (OPGD) model, we analyzed agricultural, industrial, socio-economic factors as potential LES drivers. The findings indicate gradual improvement over past two decades, with spatial variations—higher upstream estuarine lower middle. Significant enhancements post-2010 were observed Shandong Province, unlike modest gains Henan. Spatial heterogeneity was evident across floodplain segments, Jitai Beach witnessing most decline, Dongying improvement, Zhengkai largest internal disparities. Economic growth reduced agricultural activities positively impacted while population growth-related contributed to its decline. suggested safety improvements LYRFP by considering spatiotemporal influencing regional protection development.

Analysis on the ecosystem service protection effect of national nature reserve in Qinghai-Tibetan Plateau from weight perspective

Ecological Indicators, Journal Year: 2022, Volume and Issue: 142, P. 109225 - 109225

Published: July 31, 2022

The analysis of the protection effect from perspective ecosystem service function (ESF) is an important basis for proposing optimal management strategies in nature reserves. Aiming at internal, external, and different types reserves National Nature Reserve Qinghai-Tibetan Plateau 1992 to 2015, this study used InVEST model analyze dynamic changes four key ESFs, including carbon storage, water conservation, soil retention, habitat quality. Based on this, protective was evaluated. main conclusions were as follows: (1) From spatial distribution pattern quality inside outside "high east decreasing low west". On time scale, stability reserve higher than that outside. (2) Among all reserves, ESF forest always ranked highest, desert lowest. (3) During 23-year period, services between 1.0821 1.0870, which areas. (4) comprehensive highest with a value 1.3169. Although ecosystems relatively weak, it has continuously increased 0.8836 0.8955 over period. ecological processes exploring their effectiveness will help strengthen understanding conservation research. development effective policies measures had positive adaptive adjustment trade-offs.

Temporal and spatial variations of ecological security on the northeastern Tibetan Plateau integrating ecosystem health-risk-services framework

Ecological Indicators, Journal Year: 2023, Volume and Issue: 158, P. 111365 - 111365

Published: Dec. 6, 2023

Ecological security is a critical guarantor of human and indeed survival closely associated with sustainable development. Yet exploration ecological assessment in alpine pastoral regions lacking, many studies have failed to perform validation analyses on results, weakening the reliability their results. In this study, an ecosystem health-risk-services framework developed assess Gannan region (GAPR) northeastern Tibetan Plateau from 2000 2020. Then, remote sensing index (RSEI) high-resolution images are then introduced verify compare results’ reliability. Our study results indicate: (1) The can better reflect actual state GAPR, correlation coefficient (R2) comprehensive (CESI) RSEI between 0.426 0.555 (p < 0.001). (2) CESI value GAPR shows fluctuating increasing trend 2020, spatial distribution pattern high values south low north. levels dominated by medium, medium-high levels. (3) centers gravity medium-low show northward movement trend, while that southward movement. provides new perspective for methods, which be extended other regions, contribute useful references decision-makers socioeconomic development eco-environmental protection GAPR.
