概括
中国成都-重庆经济圈的城市化正在迅速增加生态和环境问题. 这项研究使用了夜间灯光和遥感数据来分析城市化和生态环境 (UE) 的合协调,发现大多数城市需要进一步的城市化,以实现可持续发展.
科学领域:
- 环境科学 环境科学
- 城市规划 城市规划
- 遥感 遥感 遥感 遥感
背景情况:
- 在西方发展战略下,中国成都-重庆经济圈 (CCEC) 的快速城市化带来了生态和环境挑战.
- 了解城市化和生态环境 (UE) 之间的相互作用对于该地区的可持续发展和保护工作至关重要.
研究的目的:
- 客观地评估CCEC的城市化水平和生态环境质量.
- 使用修改模型量化城市化与生态环境 (UE) 之间的合协调程度.
- 为了确定欧盟合协调针对性政策干预的空间模式和趋势.
主要方法:
- 利用全面的夜间光线指数 (CNLI) 来评估城市化水平.
- 使用遥感生态指数 (RSEI) 来评估生态环境质量.
- 应用了修改后的合协调度模型来量化CNLI和RSEI之间的关系.
主要成果:
- 城市化水平在CCEC显示了与去年相比的一致的增长,形成了一个以双胞胎城市为中心的循环模式.
- 生态环境质量表现出波动的上升趋势,周边地区的质量更高,中心地区的质量更低.
- 总体而言,欧盟的合协调正在改善,特别是在最近几年,空间模式从"双核"向外减少;然而,5个城市实现了协调发展,而大多数其他城市由于城市化不足而滞后.
结论:

01:17Design Example: Analyzing Capacity Contours for Flood Risk Assessment
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...

01:29Environmental Influences on Intelligence

Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children...

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

00:57Population Growth
25.3K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...
