概括

本研究引入了一种新的模糊方法来评估低影响发展 (LID) 的好处,将环境,经济和社会因素整合起来,以便在社区层面进行强有力的规划. 结果突出了具体的LID策略,以有效地减轻洪水和减少排水.

科学领域:

环境工程环境工程
城市规划城市规划
决策科学决策科学决策科学

背景情况:

使用传统的多标准决策方法来评估低影响发展 (LID) 的好处,由于混合数据源的不确定性而受到挑战.
这可能导致不准确的结果,并影响不同LID策略的排名.
需要一个强大的框架来全面评估LID在社区层面的好处.

研究的目的:

开发和提出一个多指标模糊的综合效益评估方法,用于选择有效的LID措施.
提供一个强大的和整体的框架来评估LID在社区层面的好处,解决决策中的不确定性.
为地方决策者确定实际的LID实施优先事项.

主要方法:

综合数量 (环境,经济) 和质量 (社会) 指标.
使用风暴水管理模型 (SWMM) 和ArcGIS进行基于场景的分析.
利用犹不决的模糊语言集和以类似于理想解决方案的优先顺序 (TOPSIS) 技术在不确定性下进行决策.
整合了犹不决的模糊加权平均算法和多回报期情景 (5,10,20,50,100年) 以提高稳定性.

主要成果:

在各种降雨情景下,评估了成龙路分区的26个LID配置.
确定LID措施,特别是沉没的绿地和透性铺路,显著减少排水和峰值流量.
在多个回归期内,选定的LID策略的洪水缓解能力得到了改进.
结果显示了当地决策者的实际实施优先事项.

结论:

提出的犹不决的模糊综合性评估方法为选择LID措施提供了一个强大的框架.
集成SWMM,ArcGIS和模糊决策方法有效地处理好处评估中的不确定性.
选定的LID配置,特别是绿色空间和透性铺路,对于城市洪水减缓和流水管理有效.

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...

Manipulation and Analysis

Manipulation and Analysis

GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance

Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the...

Sustainable Development

Sustainable Development

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.

Frustration and Conflict: Approach-Approach, Approach-Avoidance

Frustration and Conflict: Approach-Approach, Approach-Avoidance

Frustration occurs when people are obstructed or prevented from achieving a desired goal or fulfilling a perceived need. For example, when someone's input is ignored in a discussion, it can lead to feelings of frustration. Conflict, however, arises from opposing interests, goals, or actions. Conflicts can take various forms based on the nature of these opposing desires or goals.
One common type of conflict is the Approach–Approach Conflict. In this case, a person faces two desirable...

Factorial Design

Factorial Design

Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...
