摘　　要：对黄河源区黑土滩上建植的垂穗披碱草人工草地利用太阳能提灌系统进行喷灌试验,通过50d的灌溉试验后,对人工草地的物种多样性和土壤水分进行了研究。结果表明:灌溉区和对照区植物群落多样性指数、物种丰富度指数、均匀度指数、生态优势度指数均为对照区>灌溉区;灌溉区每个土层土壤含水量均显著高于对照区(P﹤0.05)。Elymus nutans growing in cutivated grassland in Black -soil beach in Yellow Klver source area were studied by solar energy spray irrigation during 50d irrigation. Biodiversity and soil moisture were studied. The results showed that the shannon - wienner index, abundance index, evenness index and simpson index in smaller than that of controll group. The soil moisture in every different soil layers in irrigated irrigated aveR are area was significant greater than in control group （ P 〈 0.05 ）.
