中文摘要	于2018年选取克里雅河下游为研究靶区布置监测断面,设置2条监测带,纵向沿河方向1条样带(共11个监测断面),横向选取3个典型断面,距河道不同距离布点(共8个监测点),获取乔灌草植被长势及每个断面地下水埋深数据。通过对研究区植物生长状况、群落分布情况的分析,讨论了植被长势与地下水埋深的关系,得出:①沿河道方向,地下水位影响植物群落的分布,监测断面1 ~ 6地下水埋深较浅,主要为芦苇(Phragmites australis)群落;断面7 ~ 11地下水埋深不断下降,则以胡杨(Populus euphratica)群落为主。②在垂直于河道500 m范围内,越往荒漠方向植被盖度越小,地下水埋深越深,各长势指标分别在距离河道150 m、200 m、300 m、400 m、500 m处差异显著(P <0.01);③不同植物的生长对于地下水埋深的要求不同,骆驼刺(Alhagi sparsifolia)、甘草(Glycyrrhiza uralensis)等浅根植物更容易在浅水位下生长,胡杨、柽柳等深根植物在深水位更占优势。在地下水位较深断面(7 ~ 11)与较浅断面(1 ~ 6)植物平均高度分别为100.50 cm和149.38 cm,后者较前者高出48.64%。
英文摘要	In 2018,the lower part of the Keriya River was selected as the monitoring section for the research target area.Two monitoring belts were set up,and a sample belt along the longitudinal direction of the river was selected,with a total of 11 monitoring stations.Three typical sections of riverine vegetation were selected at different distances from the river,making a total of eight monitoring points,to obtain information on the growth of the arborshrub vegetation community and the groundwater depth of each section.Through the analysis of the status of vegetation growth and community distribution in the study area and discussion of the relationship between vegetation growth and groundwater depth,it is found that in the direction of the river,the groundwater level affects the distribution of plant communities.The groundwater depth of the monitoring sections 1-6 is shallow,and the vegetation is dominated by Phragmites australis.The depth of groundwater in sections 7-11 is decreasing,and the vegetation is dominated by Populus euphratica.Within 500 m of the river channel,the vegetation coverage in the desert direction is sparser,and the depth of the groundwater is deeper.In addition,the growth indicators are significantly different at 150,200,300,400,and 500 m (P <0.01).We found that different plants have different requirements for groundwater depth:Algagi sparsifolia,Glycyrrhiza uralensis,and other shallow-rooted plants were more likely to grow where there is a shallow water table,and deep-rooted plants,such as Populus euphratica and Tamarix spp.,were more dominant where there was a deep water table.In the deeper (7-11) and shallower (1-6) sections of the water table,the average height of the plants was 100.50 and 149.38 cm,respectively,and the latter was 48.64% higher than the former.
