Ecological Benefit Evaluation Of Artificial Forest In Desert Area In MoYu County

In this paper,the eco-industrial demonstration area of Bostanykule in Moyu County was selected as the experimental site.The ecological benefit evaluation system of the plantation in the desert area of Moyu County was constructed according to the ecological characteristics of the experimental area.Forest ecosystem productivity,forest canopy density,total coverage,carbon sequestration and oxygen release rate of the forest ecosystem,the ecological stability of the plantation,forest ecological stability,carbon fixation and oxygen release,soil improvement,soil conservation water,soil organic matter and total nitrogen,total phosphorus,total potassium,soil bulk density,soil water content and water holding capacity of litter were taken as the index layers.Six typical forest plantations of the desertification zone of Mo Yu County Elaeagnus angustifolia(Elaeagnus angustifolia L.)forest,Tamarix(Tamarix ramosissima Leded.)forest,Xinjiang popular(Populus alba var.pyramidalis Bunge)forest,Elaeagnus angustifolia × Xinjiang popular mixed forest,Elaeagnus angustifolia × Tamarix forest,Elaeagnus angustifolia × Xinjiang popular × Mulberry(Morus alba L.)mixed forest were analyzed.The evaluation results show that according to the ecological benefit evaluation,Xinjiang poplar forest in the desert area of Moyu county is the best among the six typical forest stands in the desert area of Moyu county,which shows that this stand structure to adapt to the local environment in all aspects of the benefits that are the ecological stability,carbon fixation and oxygen release,soil improvement and conservation of water sources,ecological benefits play a significant role.When focusing on the benefits of specific individual,artificial forest should be based on stand.That is concerned about the ecological stability of the forest,the focus should be mainly in Xinjiang popular afforestation.When we concern in carbon fixation and oxygen release,we should focus on Xinjiang poplar forest.The main afforestation in the attention to soil improvement,we should focus on mixed forest of Elaeagnus angustifolia and Tamarix hybrid forest.Tamarix afforestation should be focused on,as soil water conservation in the concerned aspects.
