摘  要：
选择了青海湖防沙治沙措施区,通过野外调查、采样和室内实验分析,对该措施区及流动沙区的土壤微生物数量及垂直分布特征进行研究。结果表明:(1)微生物总数量为沙岛半固定沙丘>克土丘间地>克土灌丛>沙岛灌丛>湖东种羊场草方格区>流动沙丘>克土沙棘草方格>克土青杨草方格>示范区近年设置的草方格区。(2)早期治理区,植被覆盖较高,微生物数量垂直分布表现为上层的高于下层,微生物含量也较其他点高。(3)流动沙丘及草方格治理的沙丘,微生物数量非常少,而且下层的稍高于上层,这是因为流动沙丘下层土壤水分状况较好。

摘  要：
The desertification combating areas around Qinghai Lake were selected in the study.The number and characteristics of soil microbe were examined through field survey and sampling and laboratory test.(1)The areas,in order of decreasing soil microbe gross,were semi-fixed dune in sand island,the lowland between sandy dunes in Ketu,shrubs in Ketu,shrubs in sand island,straw checkerboard barriers zone in Hudong sheep stud,mobile dune,straw checkerboard barriers zone planted with Hippophae thibetana Schlechtend.in Ketu,straw checkerboard barriers zone planted with Populus cathayana Rehd.in Ketu and straw checkerboard barriers zone recently set in the demonstration area.(2)In early combating areas,the vegetable coverage was high,the vertical distribution of soil microbe showed that the amount in topsoil(0— 10cm)was much more than subsoil layer(10—30cm),and the content of soil microbe was richer than other sample plots.(3)In the mobile dunes and straw checkerboard barriers combating areas,soil microbe was very few,and its number in lower layer was a little higher than the upper layer,due to the better situation of soil water content in the lower layer of mobile dunes.
