| 摘 要： | 采用样方法,调查了盐池沙地主要植物群落,并测定了4-10月各主要植物群落样地的土壤含水量,研究了不同植物群落土壤含水量的季节动态.结果表明.在根层以下为不透水层的平沙地,各样地平均土壤含水量由小到大依次为:赖草(Leymus secalinus)群落(4.91%)<猫头刺(Oxytropis aciphylla)群落(7.42%)<柠条(Caragana korshinskii)群落(10.36%)<黑沙蒿(Artemisia ordosica)群落(12.55%)<裸地(16.27%);同一植物群落(包括裸地)的土壤含水量在各个季节也不相同.在进行沙地植被建设时,适宜采用柠条和黑沙蒿,并注意控制其合理密度及配置比例,以期达到长期稳定的治理效果.

| Abstract: | Investigation was carried out on the main plant communities in Yanchi sandy land by sampling method and soil water content was measured on each sample plot,as well as the seasonal change of soil water content in the different plant communities.Results show that plant communities on the flat sandy land with impermeable stratum below root layer,in terms of average soil water content in different plots,ranke in the ascendant order of Leymus secalinus community (4.91%),Oxytropis aciphylla community(7.42%),Carag... |
