Classification of Ecological Species Groups (ESG) in plant community analysis is one method to describe vegetation and relating them to environmental factors. This study was conducted to recognize ESG and their relationships with some environmental factors in Chamanbid-Jozak protected area from 2014 to 2016. This area is located in the eastern part of North Khorasan province, Iran. The study ar...

satellite imagery was used as a rapid and spatially explicit method to delineate crop residue cover and to estimate the use and intensity of conservation tillage. the potential of multispectral high-spatial resolution of worldview-2 local data was evaluated using 11 satellite spectral indices and linear spectral unmixing analysis (lsua). experimental plots were examined; residue cover was measu...

The vegetation of Eshtehard salt marshes in Karaj was studied, using the Braun-Blanquet method. Sixty five relevés recorded in different salt habitats were analyzed by Analyse Factorielle des Correspondances (AFC) and Classification Ascendant Hierarchique (CAH) methods, using the Anaphyto software. In general, 11 plant associations determined in the area: Aeluropodetum littoralis, Artemisietum ...

in many studies, topographic factors have been considered as an important factor in establishing the vegetation in different ecosystems. so, it affects vegetation composition and diversity by influencing soil moisture, fertility and soil depth. the aim of this research was to investigate the effects of slope, elevation and geographical aspects on species growth, forage production and vegetation...

the preparation of vegetation cover maps by used the land inventory and a traditional method has a lot of cost and time. but today, remote sensing is one of the main sources of data collection and information production for study and monitoring land resources, and was efficient tools for providing quickly and timely data and information needs for program planning in the natural resource filed. ...
