Summary
This summary is machine-generated.Ecosystem services in Baicheng City improved from 2000-2020, showing primarily synergistic relationships. Spatial analysis revealed ecological function zoning based on these services, aiding land planning in fragile regions.
Area Of Science
- Ecology
- Environmental Science
- Spatial Planning
Background
- Understanding trade-offs and synergies in ecosystem services is vital for effective ecological zoning and land management.
- Baicheng City, a case study in western Jilin Province, faces ecological fragility, necessitating targeted environmental strategies.
Purpose Of The Study
- To evaluate the spatial and temporal evolution of key ecosystem services (windbreak/sand fixation, water conservation, carbon storage, soil conservation) in Baicheng City from 2000 to 2020.
- To analyze the trade-offs and synergistic relationships among these ecosystem services and identify influencing factors.
- To propose ecological function zoning based on identified ecosystem service bundles for informed policy-making.
Main Methods
- Employed the InVEST and RWEQ models for ecosystem service assessment.
- Utilized Spearman correlation analysis and Geographically Weighted Regression (GWR) to explore inter-service relationships.
- Applied Geo-detector to identify influencing factors and Self-Organizing Maps (SOM) for ecosystem service bundle identification and zoning.
Main Results
- All four assessed ecosystem services showed improvement between 2000 and 2020, with a spatial pattern of higher values in the west and lower in the east.
- Spearman correlation and GWR analyses confirmed predominantly synergistic relationships among ecosystem services, with synergy areas exceeding trade-off areas.
- Fractional Vegetation Cover (FVC) and Normalized Difference Vegetation Index (NDVI) were significant drivers, with factor interactions having greater explanatory power than single factors.
- Four distinct ecosystem service bundles were identified: windbreak/sand fixation, ecological conservation, grain production, and ecological potential, leading to proposed ecological zoning.
Conclusions
- Ecosystem services in Baicheng City exhibit synergistic trends and have improved over two decades, influenced significantly by vegetation cover and its interactions.
- The identified ecosystem service bundles provide a robust framework for ecological function zoning, enabling tailored management strategies for ecologically fragile areas.
- The study offers crucial data for environmental protection, land use planning, and policy formulation in similar ecologically vulnerable urban environments.

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.
Multiple species cannot occupy the exact same niche within their habitat. If the niches of two or more species overlap to a large extent, the competitive exclusion principle dictates that one species will outcompete the...
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.
Ecological disturbances can be caused by an event as small as the trampling of underbrush to an incident as wide-ranging as a...
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:
Inorganic mineral matter, which constitutes about 40 to 45 percent of the soil volume.
Organic matter, also known as humus, which makes up about 5 percent of the soil volume.
Water and air, covering about 50...
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
Overview
An ecosystem is the interaction between all abiotic and biotic factors in an environment and can be classified as terrestrial or aquatic. Terrestrial ecosystems are categorized based on the climate, including annual temperature, rainfall, and seasonality. Aquatic ecosystems are separated further into freshwater and marine, and then by depth, which influences water temperature and the amount of sunlight that penetrates the water.
Terrestrial Ecosystems
Terrestrial ecosystems are...
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.
Perforation and dissection often occur during the initial stages of...
