The national ecological security barrier holds a pivotal position within the framework of strategy for conservation and restoration. Concurrently, border areas, as focal point homeland strategy, have garnered considerable attention. These two concepts collectively present profound implication upholding security. To this end, monitoring changes barriers, exploring driving mechanisms such constitutes foremost imperative in comprehending advancing theory. However, current research has yet to extend application theory scale.This paper integrates with China's land cities belt, constructing Ecological Security Barrier Land Borders (ESBCLB). Then, produces Remote Sensing Index (RSEI) products early 21st century (2000–2021, 21 periods) by using Google Earth Engine (GEE). Based on pixel scale calculations classifications, spatial-temporal evolution characteristics patterns ESBCLB are objectively obtained. Finally, employs Geographically Temporally Weighted Regression (GTWR) model explore six primary indicators, namely, economy, human activity, transportation, topography, hydrography climate, which may impacts environment ESBCLB. Through analysis, concludes that (1) On whole, not substantial, regions where remains unchanged accounting 73.78%. Among occurred, those north Aksu Prefecture Kizilsu Kirgiz Autonomous exhibit predominantly improved trend, while south show degraded trend. (2) ten identified based characteristics, pattern no significant change persistence well counter persistence. Apart from these, very better dominate majority cases; (3) Overall, hydrography, climate spatial heterogeneity RSEI. them, positive correlations RSEI While economy transportation negative correlations. significance lies it provides scientific basis theoretical support specific study regional environment.

Spatiotemporal variations and driving forces analysis of ecosystem water conservation in coastal areas of China

Ecological Indicators, Год журнала: 2024, Номер 162, С. 112019 - 112019

China's coastal zones, characterized by their ecological vulnerability and significant economic growth, demand effective water conservation management. Such management is pivotal not only for safeguarding resources but also ensuring stability promoting sustainable socio-economic development. In this study, based on the balance model, spatiotemporal dynamics of in ecosystems areas from 2001 to 2021 were three dimensions: overall, zonal, raster. The results show that: ① distribution pattern ecosystem "high south low north", with a total amount 117.726 billion m3/a, Pearl River Delta Southwest Coastal Areas as main high-value areas, overall its capacity " decreasing-rising-decreasing" pattern. fluctuating trend "falling-rising-falling". Additionally, varied significantly among different vegetation types across marine-terrestrial gradients, highest recorded evergreen coniferous forests situated 140 km coastline. ②From 2021, exhibited temporal patterns spatial differentiation along gradient. research suggests that these change are intricately linked stages regional development strategies construction within zones. ③In mere 11.63 % rasters showed changes conservation, dominated highly increases, mainly Southeast Area, Areas, Bohai Bay Area. This included such Yangtze silty plain area, sandy silt hilly terrace area western Guangdong Guinan, other China protection forest system projects. ④ Water function demonstrates profound interconnection both natural determinants. Natural elements elevation, slope, precipitation positively correlate metrics.

Spatial non-stationarity of water conservation services and landscape patterns in Erhai Lake Basin, China

Ecological Indicators, Год журнала: 2023, Номер 146, С. 109894 - 109894

Опубликована: Янв. 17, 2023

Understanding the relationship between water conservation service (WCS) and landscape patterns is important for ecosystem management resources regulation. However, existing studies on services pattern mainly focus impact of composition WCS, but ignore spatial effects configuration. Taking Erhai Lake Basin as an example, this study quantified temporal distribution WCS analyzed changes in configuration from 1990 to 2020. Subsequently, non-stationarity was discussed by using a geographically weighted regression model. The results showed that urban forest landscapes increased 3189.96% 18.34%, while grassland, shrub, cropland decreased 21.30%, 20.65%, 16.23%, respectively, fragmentation degree increased, other decreased. heterogeneity overall decreased, aggregation increased. 15.82% 2020, it derived landscape, which contributes more than 91% WCS. were spatially heterogeneous. mean patch density largest index positively affected 66.80%–82.88% 64.35%–72.42% regions, whereas area negatively impacted 66.64%–82.41% regions.

The construction of marine ecological security barriers (MESBs) is fundamental for the sustainable development environment and economy, an important component strategy land-sea integration. It difficult to build effective MESB simply by relying on power government; therefore, this respect, it urgent encourage multiple participating subjects work together. This study takes Bohai Sea as research object, uses evolutionary game theory construct a model decision-making behavior among enterprises, local governments, public in process Sea, so explore strategic stability equilibrium point through analysis interests three decision makers, lay foundation promoting process. results are follows: (1) Local government regulation key promote transformation from policy documents goal practice; moreover, directly influences whether main sources land-based pollution, i.e., will abandon traditional approach production actively MESB. (2) supervision reporting can be used synergistic, auxiliary means. Thanks government’s publicity education, develop social awareness security, which turn ensure better governments and, thus, active participation enterprises Sea. (3) Participation costs, benefits, corporate image, fines, other factors considered choice with different having marginal effects at stages. Finally, proposes measures further clarify roles functions stakeholders balance subjects, provide implementation path realization “Ocean Power”.

The Qinghai–Tibet Plateau is a proven essential water conservation region in Asia. However, various factors, such as anthropogenic activities, climate, and vegetation significantly affect its conservation. Along these lines, deep understanding of the spatiotemporal patterns for this plateau relevant influencing elements considered great importance. This paper calculates on based InVEST model, given that evapotranspiration data are an important parameter study selects mainstream to compare accuracy simulated yield, also most accurate remote sensing examined carry out Plateau. Due large area types climate ecological zones, analyzes spatial temporal variations each zone division detects factors affecting by using geo-detector method. From our analysis, following outcomes proven: Plateau, (1) overall decreased from southeast northwest; (2) studied 1990, 2000, 2010, 2020 was 656.56, 590.85, 597.4, 651.85 mm, respectively; (3) precipitation, evapotranspiration, NDVI exhibited positive relationship with conservation; (4) precipitation factor had biggest impact distinctions resource governance; (5) above combined slope interaction improve Our work provides valuable insights further implementation projects view enhancing management methods.
