Ecological Drought Monitoring of Middle Zagros Based on Landsat 7 Satellite Data and Climate Data (Case Study: Lorestan Province)

Hamid Reza Matinfar; Aliakbar Shamsipor; Hadis Sadeghi

Volume 15, Issue 3 , September 2023, , Pages 125-142


  Vegetation plays an important role in protecting water and soil resources, stabilizing carbon and improving air quality. In Middle Zagros, forest and pasture vegetation is very important in terms of protecting soil and water resources and sustaining economic activities. In this research, using the Google ...  Read More

Evaluation of Soil Organic Carbon Storage in Different Land Uses Using Partial Least Squares, Geostatistics, M5 Tree Model and Landsat 8 Statistical Methods

Alireza Zahirnia; Hamid Reza Matinfar; Hossianali Bahrami

Volume 14, Issue 2 , July 2022, , Pages 1-18


  Organic carbon plays a activate role in environmental sustainability, soil quality and health index, so identifying the spatial distribution of carbon sequestration is a requirement of environmental planning and soil management. The purpose of this study is to investigate the amount of carbon sequestration ...  Read More

Evaluation of the Efficiency of Spectral Data and Indices Derived from OLI and TIRS Sensors in Estimating Soil Salinity in Arid Regions of Southern Ilam Province

Hamidreza Matinfar; foziyeh kohani; Ali Akbar Asilian mahabadi

Volume 13, Issue 4 , February 2022, , Pages 51-66


  Soil salinity is one of the most important environmental problems, and the identification and zoningof saline soils is difficult due to the need for sampling and laboratory analysis, as well as havingtemporal and spatial variability. In recent years, the use of satellite imagery has always been ofinterest ...  Read More

Comparing Different Statistical Models and Pre-processing Techniques for Estimation several chemical properties of the soil Using VNIR/SWIR Spectrum

Elham Mehrabi Gohari; Hamid Reza Matinfar; Azam Jafari; Ruhollah Taghizadeh-Mehrjardi; F khayamim

Volume 11, Issue 4 , February 2020, , Pages 47-60


  Visible and Near-Infrared (VNIR) and Short-Wave Infrared (SWIR) reflectance spectroscopy (400-2450nm), which are at least as costly and time-consuming, are widely used in the estimation of physical and chemical properties of the soil. The purpose of this study was to investigate the ability of this method ...  Read More
