Ecosystem Services (ES) and Urban Services (US) influence place liveability in a comparable manner so that assessing landscape liveability considering both types of services can result effective for landscape planning and policy-making purposes. Considering that liveability is strongly dependent also on landscape perception by local population, stakeholder involvement results essential for a mo...
Implementing watershed management without considering all aspects may lead to instability, exacerbating unfavorable conditions. Adopting an integrated management approach is necessary for any watershed system. An important consideration in decision making and planning process is to quantify ecological impacts of management using landscape ecology framework. In this regard, uncertainty quantific...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Rangeland health assessment provides qualitative information on ecosystemattributes. We examined changes in rangeland health in the Zagros semi-arid rangelands ofIran at fixed sites between 2001 and 2011, over the 10-year period. The rangelandfragments significantly declines in the quality of the vegetation, and changes in plantspecies were driven largely by seasonality, and to a lesser extent,...
Often landscape metrics are not thoroughly evaluated with respect to remote sensing data characteristics, such as their behavior in relation to variation in spatial and temporal resolution, number of land cover classes or dominant land cover categories. In such circumstances, it may be difficult to ascertain whether a change in a metric is due to landscape pattern change or due to the inherent ...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
gel sefid village is in mashayekh village in central part of ardal city of chahar mahal and bakhtiari province. in the research, quickbird satellite image in google earth software was used to introduce the landscape of this village and to recognize the whole human uses and natural spots in the study area. then the resulting map was transferred to arcgis 3.1 software and the area land use map wa...
Interrupting the processes which control ecosystem resources has dramatic impacts on the rangeland conditions. To protect ecosystems and landscape, it needs to understand the ecosystem processes which regulate the ecosystem resources. As main components of ecosystems, patches and inter-patches play important roles in energy and materials cascade. Ecologically, functional parameters such as stab...
