Assessment and Spatial Planning of Landscape Ecological Connectivity for Biodiversity Management (Case Study: Qazvin Province)
Habitat and ecosystem fragmentation and, consequently, the loss of landscape connectivity are major causes of biodiversity destruction, leading to disruption of material, energy, and information flow at the landscape scale. Given the importance of this issue, the current study aimed to evaluate the ecological connectivity and spatial planning of Qazvin Province, in order to re-establish and pro...
متن کاملHabitat fragmentation and amphibian conservation: building a tool for assessing landscape matrix connectivity.
We have attempted modelling biological connectivity for a toad population in a floodplain in the combined framework of population dynamics and landscape ecology. We took advantage of the GIS package for establishing friction maps for the focal species by attributing to each habitat type a resistance index. This approach made it possible to draw migration zones around each pond the area and the ...
متن کاملMeasuring Connectivity – a New Approach for the Geometrization of the Landscape and for the Enhancement of Cost-effectiveness in Landuse Planning
The study aims to introduce a new method and approach for measuring the diversity of connectivity with the help of the landscape geometrization, in order to create a new variable useful in landscape metrics and to decrease the costs of landscape planning if its main goal is the enhancement of connectivity. Using induction we identify the landscape elements with geometric elements, calculating t...
متن کاملEccentric Connectivity Index: Extremal Graphs and Values
Eccentric connectivity index has been found to have a low degeneracy and hence a significant potential of predicting biological activity of certain classes of chemical compounds. We present here explicit formulas for eccentric connectivity index of various families of graphs. We also show that the eccentric connectivity index grows at most polynomially with the number of vertices and determine ...
متن کاملlanduse planning, using simple capability zoning method
land and resource developoment suitability is usually achieved by landscape capability analysis. but using land capability analysis in planning process is often restricted by budget and time limitations. a simple yet effective capability analysis method is hence required, that can furnish 'planners reliable land zonning with the least data and time requirement. the optimum integration meth...
