在沙漠人工植被区，影响土壤呼吸的主要因子是水分，其次是温度与植物群落类型和发育阶段。

Soil water plays the dominant role on soil respiration in re-vegetated desert area , while temperature and the type and phrase of plant community are secondary .

流动沙地表现为强风蚀、强堆积，而高盖度天然灌丛植被区表现弱风蚀、弱堆积特点。

Mobile sandy land characterizes as strong wind erosion , strong deposition while natural shrub vegetation area with high coverage characterizes as weak wind erosion and weak deposition .

而景观驱动作用只发生于斑块较小且呈镶嵌分布的退化植被区，对于面积很大且连片分布的流沙裸地其作用微弱；
