| Summary: | Haloxylonplanting and developing artificial forests in arid lands is one of the important actions to combat desertification. In this research, tree planting (by Haloxylon aphyllum Iljin) in Dosangi Meybod in different methods including repairing, runoff control, pitting and planting in owed have been compared with control area. For this purpose, in each area, four 300 m transects were considered randomly - systematically, and 15 plots (10 m2) were randomly collected on each transect. In each plot, vegetation characteristics including total vegetation percentage, density, canopy cover, freshness and depth of root and soil characteristics including moisture, permeability and soil carbon storage were measured. The Shapiro-Wilk test were used to test of normality of the collected data, and were analyzed using one-way analysis of variance and Duncan's test. According to the results of analysis of variance, the effect of planting with different methods on crown cover, density, freshness and deep rooting of Haloxylon shrubs and the percentage of vegetation is significant at 1% level. However, its effect on permeability and soil moisture in May is significant at 1% level and on carbon storage is significant at 5% level. Increase of vegetation cover by 5.1%, density of 249.7 number per hectare, Haloxylon cover of 3.7%, freshness class 1.5, soil moisture in spring 38.1% rooting more than 3 m and permeability 8.03 cm/h was related to the planting in dry river, which had a relative success in vegetation development in this region. |
