Quantifying the Rate of Environmental Factors Effect on Astragalus verus and Agropyron trichophorum Using Decision Support System and Multivariate Analysis of PCA

Vegetation cover over time and space is the result of interactions between vegetation cover and environmental factors. Changes occurred in range covers are caused by matrix dominance, one of the most important environmental factors. Decision support system (DSS) could be used for determining the rate and importance of each factor. Actually, in methods based on […]

Changes in Soil Organic Carbon, Nitrogen and Phosphorus in Modified and Native Rangeland Communities (Case study: Sisab Rangelands, Bojnord)

Converting the native rangelands to simplified agronomic communities causes some changes in soil carbon, nitrogen and phosphorus. Establishing of perennial plant communities on formerly cultivated rangelands is expected to stabilize soil properties and increase the amount of C, N, P stored in rangeland soils, but there is little information on what plant communities are the […]

Multi-Criteria Evaluation Model for Desertification Hazard Zonation mapping Using GIS (Study Area: Trouti Watershed, Golestan, Iran)

Desertification is one of the major issues threatening human communities. Many methods have been developed for assessment and mapping of desertification hazards. In this research, multi-criteria evaluation method was used to investigate desertification process in Trouti watershed, Golestan Province, Iran. At the first step, major desertification factors were determined by doing field surveys. They were […]

Biological Models for Protecting Different Land Use in Arid Areas China

There are more than 750 counties in 13 provinces and autonomous regions constituting 30% of China lands which are facing serious problem of desertification. These areas are mainly distributed in arid, semi-arid and dry sub-humid areas in the western part of Northeast China, North central china and most of northwest china. Biological methods are the […]

Assessment of Relationships among Yield and Quality Traits in Alfalfa (Medicago sativa) under Dryland Farming System, Hamadan, Iran

Seeds of 200 accessions of alfalfa (Medicago sativa L.) were provided from Iranian natural resource gene bank and were sown as drilled plot using alpha designs/unreplicated with 2 repeated entries within all of 10 blocks under dry land farming system in agricultural research center of Hamadan, Iran during 2009 to 2010. The data were collected […]

Effects of Enclosure, Rest-delayed and Continuous Grazing Treatments on Production Rate and Vegetation Cover of SadrAbad Nodoushan of Yazd Pastures A.

In this investigation, the effects of enclosure, restal delayed grazing and continued grazing treatments on the production rate and vegetation cover were studied. Study area was SadrAbad pasture. After selecting three bands (1+1+1=3 hectare area) as three treatments in the restricted and non restricted area, they were transected to three transects. Then plots (1×2m2 ) […]

A Multi-Criteria Evaluation approach to Delineation of Suitable Areas for Planting Trees (Case Study: Juglans regia in Gharnaveh Watershed of Golestan Province)

For the successful tree establishment, an evaluation of land suitability is necessary. In this paper, we demonstrate how to implement fuzzy classification of land suitability in a GIS environment for afforestation with Juglans regia in Gharnaveh Watershed of Golestan Province in Iran. Juglans regia is one of the most important agro-forestry species in many rural […]

Simulation Model for a Nomadic Animal Production System in Southern Iran

The first motive for the determination and evaluation of an energy production system is the need to change. Such system is dynamic in nature and is influenced by many factors such as age and physiological status of individual sheep or goat, quantity and quality of available feed and environment including the management systems. Traditional pastoral […]

Relationships Among Forage and Litter Production in Three Grazing Intensities in Nodooshan Rangeland (Yazd, Iran)

Grazing management plays an important role in the continuous and economic utilization of pastures. Proper grazing management is a main factor for the accumulation of plant litter which reduces soil erosion and increase the soil permeability to keep more moisture in the soil. In current study, the effect of three different grazing intensities (low, moderate […]

Assessing Temporal and Spatial Variations of Groundwater Quality (A case study: Kohpayeh-Segzi)

Assessing the quality of groundwater is important to ensure the sustainable safe use of these resources. However, describing the overall water quality condition is difficult due to the spatial variability of multiple contaminants and the wide range of indicators (chemical, physical and biological) that could be measured. Therefore, in this case study, some water quality […]
