Summary
Urban green space (UGS) connectivity has declined over time, particularly in Ardabil city
Area of Science:
- Urban planning and landscape ecology.
- Geographic Information Systems (GIS) and spatial analysis.
- Sustainable urban development and environmental management.
Background:
- Urban green spaces (UGS) are crucial for managing public access, stormwater, urban quality of life, and aesthetics.
- Integrating UGS into urban planning is vital for sustainable development and resident well-being.
- Assessing UGS connectivity is essential for effective urban ecological management.
Purpose of the Study:
- To calculate Urban Green Space (UGS) connectivity in Ardabil city using graph-based metrics across different time periods and population growth rates.
- To compare UGS connectivity across four municipal zones and analyze changes at various distance thresholds.
- To evaluate the trends and spatial variations in UGS connectivity.
Main Methods:
- Utilized graph-based metrics to quantify UGS connectivity.
- Analyzed changes in connectivity indices over consecutive periods and across different municipal zones.
- Evaluated connectivity at various distance thresholds for UGS patches.
Main Results:
- UGS patch sizes have decreased over time, with a general decline in connectivity (dNL) across various distances.
- UGS connectivity decreased in municipal zones 1, 2, and 3, but showed an increase in recent years after a decline until 2012.
- Zone 4 exhibited the highest UGS connectivity due to new urban development and effective UGS allocation.
Conclusions:
- Declining UGS connectivity necessitates strategic urban planning to balance conservation, public health, and social equity.
- Future urban development must prioritize sufficient land allocation and accessibility for UGS and parks.
- Sustainable urban development policies should focus on the strategic allocation and maintenance of UGS to enhance ecological and social benefits.

01:29Levels of Use of a GIS
46
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...

01:21Manipulation and Analysis
23
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...

01:17Design Example: Alignment of a Road Line Using GIS
47
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

01:25Selected Data About Geographic Locations
27
Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

01:30Thematic Layering in GIS
35
In the past, planning projects such as schools or public facilities required extensive manual effort to gather and compile data. Information such as property boundaries, soil characteristics, road networks, zoning regulations, and flood zones had to be sourced individually from courthouses, utility providers, and registry offices. Assembling these datasets into a coherent format often took several months, delaying project timelines.The introduction of Geographic Information Systems (GIS)...

01:28Introduction to GIS
60
Geographic Information Systems (GIS) are tools for storing, analyzing, and displaying spatial data alongside related attributes. Unlike traditional information systems that address general queries, GIS incorporates spatial components, enabling users to answer "where" and "how far." For example, GIS can process housing data linked to geographic locations like zip codes, allowing insights into population density or housing distribution through thematic maps.GIS integrates technologies such as...
