摘 要:玛曲草原在自然因素、人为因素双重影响下,沙化草原面积达5.53×10^(4) hm^(2),草原沙化导致的危害逐渐显露,植被盖度降低,天然草原草产量下降,水源涵养能力减弱,湿地面积减少,水土流失加剧,生物多样性锐减,生态平衡打破,经济发展受阻。为此,本文提出“草灌结合”模式治理沙化草原,通过鼠荒地治理、灭鼠、整地、施肥、补播和封育等生态措施修复沙化草原;设置草方格模式治理流动沙丘,通过沙丘整理、栽植适生灌木、在灌木防风带、草方格内混播搭配草种以及封育禁牧等措施,修复流动沙丘。两种治理模式的成功试点,为黄河上游草原生态修复提供依据和参考。Under the dual influence of natural and human factors,the area of desertified grassland in Maqu has reached 5.53×104 hm 2.The hazards caused by grassland desertification gradually have emerged,including decreased vegetation coverage,decreased natural grassland and grass output,weakened water conservation capacity,reduced wetland area,decreased soil erosion intensified,sharp decline in biodiversity,disrupted ecological balance,and hindered economic development.Therefore,this paper proposes a“grass irrigation combination”model to treat desertified grasslands,involving measures such as rodent control,rodent extermination,land preparation,fertilization,re-planting,and enclosure to restore desertified grasslands.Set up a grass grid model to control mobile sand dunes,and restore them through measures such as sand dune sorting,planting suitable shrubs,mixing and planting grass seeds in shrub windbreak zones,grass grid planting,sealing and grazing prohibition.The successful experimental units of two management models provide a basis and reference for the ecological restoration of grasslands in the upper reaches of the Yellow River.
