The aim of this research was to investigate changes in the plant species diversity and richness along a soil salinity gradient in the margin rangelands of Petregan Playa. After vegetation zoning in relation to soil salinity, random-systematic sampling within each zone was taken. Within each zone, three stands were selected, then, within each stand, plant vegetation cover, density and species diversity indices were measured. For ordination vegetation along the soil salinity gradient, Detrended Correspondence Analysis (DCA) method was used. The results showed that there were significant differences in the plant total cover, annuals and perennials plant cover between different soil salinity zones. Also, the soil salinity gradient has a significant effect on the species richness and diversity, as the first zone (high salinity) has the lowest species richness and diversity. It can be concluded that, in general, only high salinity level has a significant effect on the plant species diversity.

Soil and vegetation were sampled in three sampling areas (Control, Curved pits, Catchment ponds) using randomly-systematic method and in each site (50 hectares), 98 plots were sampled with intervals of 70 m within plots of 1*2 m and in total, 294 plots were used. Yearly growth of the vegetation was cut within 25% of the total plots (294) and was dried and its weight was considered as vegetation production. Twenty percent of total plots related to vegetation cover in each site were selected and two soil samples were sampled in each plot to evaluate soil moisture variation in two depths. The results revealed that the cover percentage as well as vegetation production increased at about 2 times in catchment ponds site and 1.5 times in curved pits site in comparison to the control site. According to the results, it seems that catchment pond method has better performance in comparison to the curved pit for increasing soil moisture and vegetation production and therefore priority of these systems can be advised for rangeland improvement and reclamation in arid lands.

The aim of the present study was to investigate the effects of fire on some chemical properties and nutrients availability in a rangeland soil. To perform this research, a fired area with a five-month history and a homogenized area close to it without fire were selected. Thirty samples of surface soil were collected by establishment of 15 plots in each area. Soil properties were analyzed using SPSS software via independent t-test. The results revealed that the rate of organic matter (2.15 folds), cation exchange capacity (21.65%) and electrical conductivity (3 folds) of fired soil were increased and the content of calcium carbonate equivalent (27.2%) and pH (4.5%) were decreased significantly. Also, the amount of total nitrogen (2.2 folds), available phosphorous (100%), potassium (66.5%), manganese (17 folds) and zinc (2.92 folds) were significantly increased in fired soil. The magnitude of available copper and iron didn’t change as influenced by fire significantly. In general, the results showed that the fertility of soil was promoted as affected by short-term fire; however, long-term effects of fire must be evaluated and compared.

In order to investigate the effects of lattice brick patterns in protection of the windbreak on the back, an experimental study was carried out in a wind tunnel. For this purpose, five lattice brick patterns with different densities, with density of 100% for the control in a randomized complete block design with four replications were studied. The results revealed that with increasing porosity in the windbreaks, while reducing wind speed and keeping the area protected; flow lines become parallel and vortex currents are not observed. While with reduced porosity, the wind streamlines the flow and becomes turbulent and reduces protection in the desired area. Also, results showed that the construction of windbreaks with a height less than the height of the protection structures (like a greenhouse), especially in high-density windbreaks, not only protect against winds not retained, but also with the formation of more rapid and vortex flows behind the windbreaks, the damage increases. Thus, attention to create optimum density with the use of appropriate lattice patterns is important in establishing abiotic brick windbreaks.

This study aims to identify the physicochemical characteristics of nebka sediments and compare its results with adjacent lands. Hence, the grain size distribution and morphometric characteristics of particles were determined for 30 samples in Sufikam plain in the Eastern border of Caspian Sea. Then, the relationships between the physicochemical properties were compared using Wilcoxon and T-test at 95%. Results showed that the prevailing wind direction is west to east which in our case is from sea to land. Analysis of sand rose graph indicates that the winds in spring and summer blowed the sediments from soil surface. Results showed that there were no significant differences between sorting of particles, fraction of very fine sand, silt, clay, EC, pH and organic carbon of nebka's head samples and its adjacent land. However, results of skewness index, mean diameter of fine sand, medium sand, coarse and very coarse sand, SAR and ESP proved to be statistically significant. Therefore, it can be concluded that the source of sediments is local.

In this study, the geomorphological units of Yazd-Meybod road margin were distinguished, and the samples were taken from these facies as origin area while roads sediment as the transition area of sediments. The samples were analyzed using morphometric indices and microscopic mineralogy; then, its results were compared using cluster analysis method. The results showed that the median and mean of road sediment grain is 208 and 224 µm, respectively which according to the relationship between transportation distance and diameter of grains in deposition area prove that the origin area could be close to sedimentation area. The skewness index of grain size distribution tend to show coarser grains and poor sorting for road sediments which revealed the local transportation area of sediment particles. The results of mineralogy between road sediments and geomorphological facies around the road showed that the aeolian sediments crossing the road were more similar to sand sheets and sand dunes which can be introduced as the source area of aeolian sediments on the Yazd- Meybod road.
