Summary
Comprehensive human settlement suitability in the Yangtze River Delta (YRD) was evaluated using multi-source data. Shanghai and Zhoushan exhibit the highest suitability, indicating optimized land use for population and economy.
Area of Science:
- Human Geography
- Environmental Science
- Regional Planning
Background:
- Assessing human settlement suitability is crucial for quality of life and regional development.
- Existing research lacks comprehensive evaluations of human settlement suitability, particularly in key economic zones.
- The Yangtze River Delta (YRD) is a vital region requiring detailed suitability analysis for sustainable development.
Purpose of the Study:
- To conduct a comprehensive evaluation of human settlement suitability in the Yangtze River Delta (YRD).
- To analyze the spatial differentiation of natural and human environmental factors influencing settlement suitability.
- To develop and apply human settlement suitability indexes using multi-source data.
Main Methods:
- Integration of multi-source data, including digital elevation models, Landsat imagery, and meteorological data.
- Construction of human settlement suitability indexes incorporating natural and human environmental elements.
- Spatial analysis to identify patterns and variations in settlement suitability across the YRD.
Main Results:
- Natural environment suitability is influenced by topography and proximity to the sea, with spatial variation from southwest to northeast.
- Human environment suitability is higher in urban areas and decreases from south to north.
- Shanghai and Zhoushan show the highest comprehensive human settlement suitability, while Huaibei and Xuzhou rank lowest.
Conclusions:
- Comprehensive human settlement suitability in the YRD is a result of combined natural and human environmental factors.
- Areas with high suitability indexes are significantly utilized, with a strong correlation between suitability, population, and economic activity.
- Findings provide critical insights for optimizing land use and regional planning in the Yangtze River Delta.

87
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.

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...

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...

Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...
