Cluster Sampling Method01:20

Cluster Sampling Method

Appropriate sampling methods ensure that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. All the members from these clusters are in the cluster sample. For example, if you randomly sample four departments from your...
Sampling Plans01:23

Sampling Plans

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...
Scatter Plot01:15

Scatter Plot

The most common and easiest way to display the relationship between two variables, x and y, is a scatter plot. A scatter plot shows the direction of a relationship between the variables. A clear direction happens when there is either:
Thematic Layering in GIS01:30

Thematic Layering in GIS

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)...
Distribution and Dispersion00:54

Distribution and Dispersion

Ecology is the study of how organisms interact with their environment and with one another. An important aspect of ecology is understanding where species are found and how individuals are distributed within those areas. The geographic range of a species refers to the total area where its members are located, while dispersion describes the pattern of spacing of individuals within that range.Geographic Range and Dispersion PatternsWithin a species’ geographic range, individuals may be distributed...
Manipulation and Analysis01:21

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...

Area of Science:

  • Spatial analysis
  • Geographic Information Systems (GIS)
  • Landscape ecology

Background:

  • Regionalization organizes multivariate spatial data for better visualization and synthesis.
  • Landscape pattern indices quantify land cover composition and configuration.
  • Forest patterns are influenced by harvesting, human activities, and topography.

Purpose of the Study:

  • Develop an approach to investigate forest pattern distribution.
  • Identify regions influenced by anthropogenic activities and topography.
  • Utilize regionalization for landscape pattern analysis.

Main Methods:

  • Generated spatial pattern regions (SPR) using a regionalization approach.
  • Employed multivariate cluster analysis (CLARA algorithm) on land cover data.
  • Analyzed data from Prince George and Quesnel Forest Districts, British Columbia.

Main Results:

  • Six SPR were generated, with SPR2 being the most prevalent (22% of study area).
  • SPR2 landscapes averaged 55.5% forest cover.
  • SPR2 exhibited high fragmentation with numerous patches and forest/non-forest joins.

Conclusions:

  • Regionalization of landscape pattern metrics is effective for examining forest pattern distribution.
  • SPR can identify areas for conservation and management based on environmental conditions.
  • The approach aids in understanding the spatial impact of various factors on forest landscapes.
