Summary
This summary is machine-generated.Ecological networks in the Taihang Mountains expanded from 2000-2020, increasing source areas and corridors. This study analyzed ecosystem services to guide ecological protection and economic development.
Area Of Science
- Ecological network construction and spatial analysis.
- Ecosystem service assessment and land use change.
- Regional ecological security and sustainable development.
Background
- Balancing ecological protection and economic development is crucial.
- Ecological networks are vital for regional environmental security.
- Understanding ecological network evolution aids conservation strategies.
Purpose Of The Study
- To construct and analyze the spatiotemporal evolution of the ecological network in the Taihang Mountains.
- To identify ecological source areas and corridors using ecosystem service functions and spatial patterns.
- To provide scientific insights for regional ecological security and sustainable development.
Main Methods
- Calculating four key ecosystem service functions (water conservation, carbon storage, soil conservation, habitat quality).
- Employing Morphological Spatial Pattern Analysis (MSPA) to identify ecological source areas.
- Utilizing circuit theory to extract ecological corridors and analyze network evolution.
Main Results
- Ecological source areas in the Taihang Mountains increased from 13,168.76 km² to 15,007.17 km² between 2000 and 2020.
- The number of ecological corridors increased from 101 to 105, with important corridors rising from 84 to 86.
- Ecological pinch points and barrier restoration areas showed dynamic changes, with pinch points exceeding 20,000 km².
Conclusions
- The ecological network in the Taihang Mountains has expanded, enhancing connectivity.
- Spatial patterns of ecological corridors and critical areas require targeted management.
- Findings support evidence-based strategies for integrating ecological protection with economic development.

In population modeling, integration provides a systematic way to determine accumulated quantities from known rates of change. One such application arises in ecology, where the total weight of a fish population in a body of water is referred to as its biomass. When the rate of growth of this biomass is known as a function of time, calculus can be used to determine the total biomass at a future date.Growth Rate and Biomass FunctionLet the growth rate of the fish population be represented by a...
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...
Population dynamics can be described mathematically by considering the population size P(t) as a function of time. The rate of change of the population is then represented by the derivative of P(t). A simple assumption is that the rate of growth is proportional to the size of the population itself. This leads to an exponential growth model, where the population increases rapidly without bound. While this is a useful first approximation, it does not reflect realistic long-term...
