概括
安宁河流域的土地利用变化显著影响生态系统服务价值 (ESV),生态生产 (E-P) 土地扩张减少了整体ESV. 可持续发展需要综合土地管理,考虑到生态和社会经济因素.
科学领域:
- 生态经济学生态经济学
- 环境科学环境科学
- 地理信息科学 地理信息科学
背景情况:
- 安宁河流盆地是板西经济区的战略枢纽,表现出脆弱的生态,面临着巨大的土地治理挑战.
- 了解土地利用转型对生态系统服务的影响,对于生态敏感地区的可持续发展至关重要.
研究的目的:
- 评估土地利用转型对安宁河流域生态系统服务价值 (ESV) 和可持续发展的影响,使用"生产-生活-生态空间" (PLES) 理论.
- 确定与土地使用动态相关的ESV变化的关键驱动因素和敏感性.
主要方法:
- 利用了1985-2023年的土地使用数据和统计年鉴.
- 应用了修改后的等价系数方法和地理信息图库 (TuPu) 来进行ESV评估.
- 采用了改进的交叉敏感性分析 (CICS) 和最佳参数地理探测器来分析土地使用影响和驱动因素.
主要成果:
- 生态生产 (E-P) 土地经历了显著的扩张 (255,893.21公, 29.05%的动态度).
- 电力土地占ESV总量的90%以上,其中监管服务占主导地位 (67%). 自2005年以来,ESV总体下降了3.26亿元,EP土地贡献了7.66亿元的下降.
- 生态系统服务对E-P土地转型表现出最高的敏感性;人口密度是影响ESV的重要因素,特别是在双变体相互作用中.
结论:
- 土地利用转型,特别是EP土地的扩张,对安宁河流域的ESV产生了负面影响.
- 高海拔地区显示ESV热点,而平原则是冷点,表明生态系统服务提供中的空间异质性.
- 综合土地管理战略,考虑到土地利用,生态系统服务和社会经济因素之间的复杂相互作用,对于生态保护和可持续发展至关重要.

The Soil Ecosystem
21.8K
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:

Threats to Biodiversity
22.9K
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...

Design Example: Analyzing Capacity Contours for Flood Risk Assessment
101
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...

Symbiosis
30.7K
Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Bioremediation
20.1K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
