Investigation of Cover/Land Use Structure of Sefidrod Watershed by Landscape Ecology Metrics

Awareness of the types of land cover and human activities as a data base of planning is important, which for optimum use of natural resources in sustainable development way to aware of ecological resources in limited time and minimum cost needed. The aim of this study has been Investigation of Cover/Land Use Structure of Sefidrood Watershed by Landscape Ecology Metrics. In this study cover/land use maps of watershed with the goal Sefidrood paper using Arc GIS 9.2 software maps the desired category and eventually became relevant measures using software Fragstat 3.3 were extracted. Measures used in the grade level (the user) in this study measures grade level, percentage area, the number of spots, total margin, shape, Land, the largest spots, the average level of spot, average spot shape index and mean nearest neighbor distances were Euclidean. Index numbers to measure tear stains classes used in this study, the largest number of spots and tear, ie the most agriculture-related classes (691) and the lowest dissociation related to the forest class (30), respectively. The highest rating land to grassland class (39/56) had the spots are more dispersed than classes and the lowest to the forest class (10/78) and in the forest of stain less dispersion of have. The highest mean Euclidean nearest neighbor distance of the amount of disruption pieces spots shows a class related to the agricultural class (6747/32 m) and the lowest value was to the forest class (908/32). User disruption in agriculture is the highest amount of fragmentation can therefore be concluded their relationship with their collection has been discontinued and the notion that this is agricultural land have less integrity (fragmented more disruption) than other classes. The use of renewable resources should be a way that do not cause disturbs the balance of the environment, becuse the change in resources due to changes in ecological structure and function of Landscape is impressive in the area. However, applying principles of landscape ecology gives an initial assessment in the landcape ecological scale that on the way for rapid assessment and scientific use and emphasized services of the nature, The prioritization each of the pathes is based on their quality. So suggested utilization princpel of landscape ecology to provide structural information to design and landuse planning.
