概括

过度的出口威胁着生态系统和人类健康. 本研究量化了东湖盆地中的出口和留,包括河流运输,以确定生态恢复的优先区域.

科学领域:

环境科学环境科学
生态系统服务生态系统服务
水质管理水质管理

背景情况:

过度向水体出口气会破坏生态系统平衡,并对健康构成风险.
量化净水服务至关重要,但河流运输在出口中的作用仍然不清楚.
了解流域气动态对于有效的环境管理至关重要.

研究的目的:

评估东湖流域的出口和水净化服务,包括分流域出口和河流运输.
分析每月留量的变化,并确定生态恢复的优先领域 (将耕地恢复为森林土地).
提出一个综合方法,更准确地评估流域出口风险.

主要方法:

利用生态系统服务和权衡的综合估值 (InVEST) 模型来模拟出口.
在评估中纳入子盆地出口流程和河流运输动态.
分析了每月的变化,并确定了基于净水服务改进的生态项目的优先领域.

主要成果:

在东廷湖以外的总负荷为11.34 × 10^8公斤/年−1,子盆地保持9.02 × 10^8公斤/年−1 (79.57%).
河流运输占总留量的1.83 × 10^8公斤年-1 (16.87%) .
净水服务在冬季/晚秋达到峰值,夏季/早秋最低. 东亭湖周围的优先区域在净水服务方面有58.15%的改善.

结论:

该研究通过整合河流运输和季节性动态,为净水服务评估提供了一种新的方法.
通过这种综合方法,可以准确评估流域出口风险.
这些发现强调了考虑河流过程和时间变化的重要性,以有效地管理和生态恢复.

The Nitrogen Cycle

The Nitrogen Cycle

Nitrogen atoms, present in all proteins and DNA, are recycled between abiotic and biotic components of the ecosystem. However, the primary form of nitrogen on Earth is nitrogen gas, which cannot be used by most animals and plants. Thus, nitrogen gas must first be converted into a usable form by nitrogen-fixing bacteria before it can be cycled through other living organisms. The use of nitrogen-containing fertilizers and animal waste products in human agriculture has greatly influenced the...

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

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...
