摘    要:在野外调查的基础上,分析了民勤不同立地条件下的人工梭梭林分布情况和生长状况。民勤人工梭梭林主要分布在绿洲边缘的流动沙丘、半固定沙丘和固定沙丘上,这3种立地条件下的人工梭梭林占民勤人工梭梭林的97.56%;在丘间平滩地、风蚀残积山坡、山前洪积扇和平缓假戈壁也有人工梭梭林分布,但是面积很少。3种主要立地条件下的人工梭梭林保存密度接近,在330株/hm2左右,保存率为26%左右,这主要是梭梭林初植时和生长的前期,立地条件接近的缘故。随着生境条件的变化,梭梭的生长状况明显不同,其中流动沙丘上的梭梭生长最好,主要体现在树体较高大、冠幅大、枝条数量多、新枝生长旺盛。

关 键 词:民勤  立地条件  人工梭梭林  生长状况

Abstract:Based on field survey,distribution and growth condition of artificial Haloxylon ammodendron forest in Minqin were analyzed under the different site.The artificial Haloxylon ammodendron forest were mainly distributed in the mobile dunes of oasis edge,semi-fixed dunes and fixed sand dune in Minqin.Under three site conditions,the artifi-cial Haloxylon ammodendron forest accounted for 97.56% of artificial Haloxylon ammodendron forest of Minqin;the distribution of artificial Haloxylon ammodendron forest were als...
Keywords:Minqin  site condition  artificial Haloxylon ammodendron forest  growth condition
