不同干扰方式对塔克拉玛干沙漠南缘荒漠植物的防风固沙效果的影响
Effects of different disturbance methods on wind-proof and sand-fixing of desert plants in the southern margin of Taklimakan Desert
摘要
Abstract
In the transitional zone between desert and oasis,addressing wind prevention and sand fixation is crucial for combating desertification.Alhagi sparsifolia,a prevalent deep-rooted species in desert,plays a vital role in this process.Unfortunately,due to improper local usage,vegetation suffered extensive damage.To examine the impact of various interference methods on the growth of A.sparsifolia and soil wind erosion,five treatments were implemen-ted:control(CK),cutting in spring(CS),burning in spring(BS),cutting in fall(CF),and flood water irriga-tion(FI).Over 13 years(2010-2023),the control group exhibited significantly greater plant height and crown width compared to other disturbance methods,and the diversity index,evenness index and species richness after FI were significantly higher than those of other interference methods.There were no differences for soil pH,electrical conductivity,total nitrogen,total phosphorus,total potassium,and available phosphorus among the various disturb-ance modes.However,FI demonstrated a significantly lower soil available nitrogen content compared to CK,while soil organic carbon and available potassium contents were notably lower than those in CS.BS exhibited a significant-ly lower soil erosion height than other disturbance methods.Additionally,soil erosion height was positively correla-ted with plant height and crown width.These findings offer a scientific foundation for better protection and rational utilization of A.sparsifolia and other desert vegetation resources.关键词
