Drought Impacts on vegetation cover an emphasis on Remote Sensing (Case Study: Salafchegan – Neizar Watershed)

Vahid Veisi; Mansoureh Ghavam; Omolbanin bazrafshan

Volume 26, Issue 3 , September 2019, , Pages 704-716

Abstract
       Rangeland vegetation is one of the most important components of arid ecosystems and it is necessary to determine changes in rangeland vegetation under drought and wet years. The present study aimed to investigate the relationship between satellite indices and SPI index in Qom ...  Read More

Evaluating the vegetation changes upon vegetation index by using remote sensing

Saiedeh Nateghi; Ahmad Nohegar; Amir Houshang Ehsani; Omolbanin Bazrafshan

Volume 24, Issue 4 , January 2018, , Pages 778-790

Abstract
  The monitoring of vegetation changes has a fundamental role in planning and management of environment. There are various methods to determine the changes in a region using satellite images that each has advantages and limitations. The use of vegetation indices is one of the methods to detect the changes. ...  Read More

ardavan ghorbani; ardashir pournemati; mohsen panahande

Volume 24, Issue 1 , May 2017, , Pages 165-180

Abstract
  The aim of this study was to estimate and map the plant group and total aboveground phytomass using Landsat 8 images in the rangelands of Sabalan Mountain. Images were selected on the 19th of July 2013 and field data were collected in April and July based on maximum matching with the phenology of the ...  Read More

Coastal desert land use monitoring using change vector analysis technique during 2001 to 2014(Case study: Qeshm Island)

Saeedeh Nateghi; ahmad Nohegar; Amir Houshang Ehsani; Omolbanin Bazrafshan

Volume 23, Issue 2 , September 2016, , Pages 416-404

Abstract
  Monitoring the land use and land cover change detection is one of the most important issues in the field of planning and management. Change Vector Analysis technique is one of the common methods to detect the changes. This method is based on radiometric changes between two time series satellite data ...  Read More

Application of digital data in mapping vegetation changes in desert area of West Karkheh

Akbar Fakhireh; Ahmad Pahlevanravi; Mahmoud Najafi zilaee; Mohsen Moradzadeh; Soheila Nouri

Volume 19, Issue 3 , December 2012, , Pages 457-468

Abstract
  Detailed studies of vegetation in desert areas are almost difficult due to the limitations and conditions of these areas. Remote sensing technology with numerous capabilities can be used as an efficient method in these areas. This study was aimed to determine an appropriate vegetation index to assess ...  Read More

Land cover and rangeland classification map using Land sat satellite image (TM) (Case study) Namrood watershed

Mahmood Goudarzi; Mahdi Farahpour; Alireza Mosav

Volume 13, Issue 3 , February 2006, , Pages 265-277

Abstract
  In Iran, like many other developing countries, high population growth rate causes unfairly uses of natural resources and consequently land cover change. Therefore, detection of land cover (rangelands, irrigated and rainfed agricultural lands, urban areas…) changes can influence local planning ...  Read More
