摘  要：
[目的]研究新疆卡拉贝利工程区植物防风固沙效果,为该地区的风沙治理措施提供理论依据,[方法]对该地区的植被进行了防风蚀效果的调查研究,主要收集了植被的盖度、冠幅、高度等植被特征和植被积沙特征的数据,采用SPSS等统计软件进行数据的统计分析,并利用曲线估计的方法建立植物形态与积沙量的回归模型,量化分析植物形态特征与植物积沙的关系。[结果]该地区植被以盐爪爪为主,并伴有少量骆驼刺、假木贼等植物;不同砾石覆盖度对植被的密度和盖度影响较大,对植物的高度、冠幅影响较小,且砾石覆盖度越高植被密度和盖度越低;植物积沙量、植物积沙丘的厚度与宽度均随着植物高度和冠幅的增加而呈指数增加;植物形态对积沙量增加的影响程度表现为:植物高度>纵向冠幅>横向冠幅。[结论]该地区植被具有一定的防风蚀能力,其防风蚀效果的大小与植被的形态以及地表砾石含量存在很大的关系。

摘  要：
[Objective]The objective of this study is to analyze the anti-erosion effect of vegetation and provide the theoretical basis for sand control measures in Kara Bailey project area of Xinjiang Wei Autonomous Region.[Methods]Plants in the study area were investigated,and the data of vegetation cover,crown width,height and characteristics of sand accumulated by pants were collected.The SPSS software was employed for statistical analysis,and regression curves were used to establish the model to quantitatively analyze the relationship between plant morphological characteristics and sand accumulation.[Results]The study area was dominated by Kalidium foliatum,and there were some other plants such as Alhagi sparsifolia,Anabasis elatior.(2)The effect of gravel cover on vegetation density and coverage was more significant than that on plant height and crown width,and vegetation density and coverage decreased with the increase of the gravel coverage.(3)With the increase of plant height and width,the sand accumulation increased exponentially.(4)The influence of sand accumulation on plant morphology showed as:plant height>longitudinal crown >lateral crown.[Conclusion]Vegetation in the study area has an anti-erosion effect,and this effect is influenced by vegetation morphology and surface gravel cover.
