开发和应用一个利用区域特征的空间生态系统健康指数 (SEHI).

主要方法:

使用了压力状态响应 (PSR) 框架.
使用分析层次过程 (AHP) 进行指标权重和主要组件分析 (PCA) 进行指标选择.
通过整合压力,状态和响应在多个时代 (1990,2003,2013,2021) 的子指数,制定了SEHI.

主要成果:

空间生态系统压力增加,而生态系统状态最初有所改善,然后在2013年恶化,显示出响应的变化.
空间生态系统健康指数 (SEHI) 的得分从1990年到2013年大幅下降,但在以后的时代有所改善.
在2021年,SEHI得分显示,Langfang的行政单位的情况中等至相对健康,尽管尚未达到1990年的水平.

结论:

自2003年以来,兰的空间生态系统健康状况有所改善,但需要进一步努力,以最大限度地降低压力并稳定生态系统状态.
开发的SEHI是政策制定者分析区域健康,指导发展战略和推动环境恢复的宝贵工具.

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Responses to Salt Stress

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Applications of GIS: Disaster Management and Emergency Response

Applications of GIS: Disaster Management and Emergency Response

Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

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...
