Accelerated urbanization has caused encroachment on urban water ecological land in China's Yellow River basin, resulting a strong disturbance of ecosystem service functions and increasingly serious environmental problems. In this study, two entities—water value (WESV) the system—are identified, to investigate interactions between WESV systems their subsystems six basin cities (Lanzhou, Yinchuan, Hohhot, Xi'an, Zhengzhou, Jinan) from 2005 2020. First, integrated level system each city is calculated using modified developed method equivalence factor per unit area entropy method, respectively. Then, coupling coordination relationship are revealed by degree model (CCDM) Geographically Temporally Weighted Regression (GTWR). The results show that: 1) both basically shows an increasing trend, hydrological regulation function dominates functions, comprehensive evaluation environment generally higher than that other system's subsystems. 2) gradually rose extreme incoordination coordination, (CCD) resources also obvious upward but CCD safety developing more slowly. 3) where have greater positive impacts primarily focused Lanzhou while negative mainly located Yinchuan Zhengzhou. summary, planning decision-making or cities, it critical promote protection ecology high-quality development clearly understanding interaction services system, coordinating balancing systems.

Promoting positive emotional experiences for tourists is crucial sustaining development in rural areas. However, existing research has limited focus on the built environment, particularly developing a framework to evaluate environmental sentiment small medium scale with detailed indicators. This study addresses this gap by examining impact of environment tourists' emotions. Natural Language Processing (NLP) technologies are employed analyze web text data and determine average index traditional villages Fuzhou, China. Additionally, were acquired through HRnet segmentation model Matlab. To assess association between indicators index, we used eXtreme Gradient Boosting (XGBoost), SHapley Additive exPlanation (SHAP) model, ArcMap software. The demonstrated that (1) spatial distribution was significant. Houfu Village (9.91), Qianhu (9.88), Ximen (9.75) had highest scores, while Doukui (−0.85), Jiji (0.2), Qiaodong (0.55) lowest. (2) have most significant Openness, Greenness, Color Complexity, contribution value above 0.7—followed Enclosure, Visual Entropy, Ground Exposure, 0.5 0.7. Furthermore, analyzing interaction mechanism showed non-linear relationship. characteristics associated high scores openness range 0.2 0.5, greenness 0.4 0.6, color complexity 0.3 0.5. provides observations pertinent sustainable village environments. findings contribute an understanding how these elements might be effectively designed improve settings.

The study of ecosystem service value (ESV) response to landscape pattern evolution has become a research hotspot in the fields geography and ecology, however, multi-scale mechanism ESV change Karst region is still unclear, which some extent restricts precise regulation regional ecosystems multi-level human-land coupling coordination. This focuses on Nanming River Basin (NMRB) Guizhou Province, representative karst basin southern China. Using various methods such as an equivalent factor, index, optimal parameter geo-detector(OPGD), we calculated ESVs, explored spatial temporal from 2000 2020, scientifically analyzed ESVs at sub-watershed scale (27 124 sub-watersheds) grid (2.4 km × 2.4 1.2 grids), respectively. results revealed that synergies have been dominant relationship between NMRB since beginning 21st century. At sub-basin scale, shape index (LSI) (21–43%) coefficient variation (SHAPE_CV) (20–35%) were main drivers geographical differentiation trade-offs/synergies among with few attenuation effect types weakened geographic differentiation. However, two-factor enhancement nonlinear exception. patch cohesion (COHESION) (4–49%) contiguity (CONTIG_MN) (15–39%) divergence trade-offs/synergies, factor interactions divergence. COHESION (3%–21%) LSI (4%–13%) became primary influences divergence, no independence or type interactions. are crucial for optimising services formulating appropriate strategies coordinating ecological-economic development regions China around world.

Ecological security patterns of Chinese lakes based on ecosystem service values assessment and human threat factors evaluation

Ecological Informatics, Год журнала: 2024, Номер 82, С. 102754 - 102754

Опубликована: Авг. 3, 2024

Sustainable provision of lake ecosystem services is essential for maintaining regional, national, and even global ecological security patterns. Scholars have been conducting in-depth research on the concept, assessment models, impact mechanisms, trade-offs, optimization services. Integrating management decisions policy design still presents significant challenges in various aspects. It necessary to a spatial pattern develop hierarchical classified control protection system. This study establishes an system service values Chinese lakes using meta-analysis evaluates distribution We propose method build patterns based value degree human threats establish framework evaluating levels ecosystems. Based dominant functions, this further determines low, medium, high-level each region. Lakes within low-level mean that higher are needed. In different patterns, proposes determine indicators monitoring intensity function types pressure threat region, promote improvement healthy development assesses as entry point level ecosystems considering their levels. The evaluation helps system, which positive significance scientific, quantitative assessment, standardization territorial planning processes.

Rapid urbanization in the Jiangnan Water Network region has resulted degradation of ecosystems and interruption ecological functions. The security pattern (ESP) is crucial for balancing economic development protection within an area. In this study, we focused on a representative Gaochun water network area devised comprehensive ESP methodology. This study combined importance ecosystem services (ESI), landscape connectivity (Con), sensitivity (ESS), starting with analysis sources. Furthermore, both natural human factors are emphasized when constructing resilience surface. Nighttime lighting data (NTL), risk index (ERI), land intensity factor (CI) were used to calibrate resistance values. Finally, circuit theory was applied determine optimal path, width, strategy points corridors. results indicate We identified 39 source areas, 74 corridors, 33 pinch points, 45 barriers. Based this, overall spatial optimization plan “five cores, three patches, belts, multiple points” obtained. aimed explore optimize approach regional characteristics, providing new pathways decision support future construction patterns region.
