چکیده
identification of rapid degradation of ecological resources requires effective environmental monitoring including ecological integrity assessment .our first aim is to analyze ecological integrity in a landscape context while developing a method to assess integrity in spite of a dearth of historical data. we used a spatial-temporal reference framework for land cover maps for assessing ecological integrity change, emphasizing changes in patch types and configuration. land cover is used as a surrogate for habitat. habitat condition is the main point of this research in assessing ecological integrity. our second aim is to recognize, through a case study of the above, the ecological integrity of the miankale peninsula of miankale biosphere reserve on iran’s caspian sea coast in the east latitude of 53 ،24 ،50ً and north altitude of 36 ،56 ،45ً . land cover data were obtained from landsat tm5 of 1985 and compared with current condition images from landsat tm5 of 2010. landscape metrics show that minakale’s natural semi-dense shrub lands are fragmented; with the number of patches increasing and average patch area decreasing. this implies a fall in habitat available to its dependent bird species. in conclusion, considering birds’ habitat and its aggregation as a measure of integrity, landscape metrics show ecological integrity of miankale has decreased and signals of habitat loss have appeared in study area. more detailed analysis in ecosystem scale is suggested as the complementary research to find the best indicator for assessing the integrity of the ecosystem.
