基于ArcGIS的艾比湖周边灌丛沙堆三维形态特征的提取与分析

艾比湖周边广泛分布着湖滨沙地化生物与风力作用下形成的灌丛沙堆。灌丛沙堆的退化演替过程通常是自然因素和人为活动对生态系统的压力综合作用的结果,是反映生态变化和气候演变的重要标志之一,因此,灌丛沙堆的产生和衰亡与土地荒漠化正逆过程关系密切。研究灌丛沙滩的空间分布格局现状,对荒漠化防治以及区域生态保护具有重要作用。本文尝试以...

The Spatial Pattern Analysis of Nebkhas in the Ebinur Lake Periphery Base on ArcGIS

There are many nebkhas around the Ebinur Lake which occur by the effect of sand biology and the wind action forms.The nebkhas are the arid area desert,half arid half moist sand and the sandy coastal zone common eolian deposit biology landform type,because the wind sand flow meets the brush to stop,the sand material and periphery piles up in the brush forms.Usually the nebkhas's degenerated succession process is result of the combination of natural factor and the artificial activity to the ecosystem pressure...
