One of the ordinary methods to protect, rehabilitate, and enhance an ecosystemfunction in arid and semi-arid areas of the world is sand dune stabilization using biologicalpractices. Plantation of species on the soil plays a great role in sustainable management ofthe ecosystem. This research studies the effects of cultivation of Haloxylon ammodendronand Atriplex canescens on physical-chemical ch...

بررسی ارزش غذایی تاغ و عمل آوری آن با سود و آهک در مراحل مختلف رشدبا استفاده از روش کیسه های نایلونی
abstract this study is carried out to determine the chemical composition in the three vegetative stages of the haloxylon sp., degradation parameters, with adding naoh and ca(oh2 ). for this purpose, in may and october and january 2010 enough some haloxylon sp. of the ammary area was prepared. crude protein and ash percentage are decrease, neutral detergent fiber percentage with pragress stage ...
The Haloxylon genus belongs to the Amaranthaceae (formerly Chenopodiaceae) family. The small trees or shrubs in this genus are referred to as the King of psammophytic plants, and perform important functions in environmental protection, including wind control and sand fixation in deserts. To better understand these beneficial plants, we sequenced the chloroplast (cp) genomes of Haloxylon ammoden...
well as providing forest products. This study refers to the identification of the land reclamation areas and potential plantation areas on the Bagmati river-basin in the Terai region of Nepal, and recommends appropriate species for plantation in order to rehabilitate such areas. Multi-temporal Landsat Satellite Images (Landsat 7 and Landsat 8) were acquired for 2002 and 2014. Object-based Image...
Desert vegetation plays significant roles in securing the ecological integrity of oasis ecosystems in western China. Timely monitoring of photosynthetic/non-photosynthetic desert vegetation cover is necessary to guide management practices on land desertification and research into the mechanisms driving vegetation recession. In this study, nonlinear spectral mixture effects for photosynthetic/no...
The arid regions are fragile and sensitive ecological environment and are vulnerable to desertification. This critical area around arid region where desertification occurs determines the ecological stability of the deserts. In order to combat desertification and decreasing its risks, the restoration projects using varieties of plant species were applied that could change the soil properties and...
Afforestation is an important and effective way to curb wind-sand hazards in the Alxa Desert. However, over-afforestation makes soil drying occur frequently. The formation of a layer seriously restricting effectiveness vegetation construction regional ecological stability. To clarify process desiccation Haloxylon ammodendron plantations determine suitable planting years, typical H. plantation t...
Haloxylon ammodendron (C.A.Mey.) Bge. is crucially important for stabilizing sand dunes in the desert area of Junggar Basin and has thus been widely planted oasis–desert ecotone windbreak fixation purposes since 1980s. The spatial distribution structural characteristics plantations three different ages—planted 1983 (36a), 1997 (22a), 2004 (15a)—on southwestern edge Gurbantünggüt Desert were stu...
In recent years, deferent methods for determination of optimal pattern of using water and soil resources have been applied. Due to importance of natural resources, watershed management through land use modification and correct application of land is necessary. However, single objective linear programming is not an efficient method in this matter. In this study, multi objective method of goal p...
