野生动物学报, 1998 新疆古尔班通古特沙漠是地表温度达40～70℃,相对湿度只有10％～30％的干旱地区,但沙漠上却发现需要水湿环境生活的绿蟾蜍.经观察,绿蟾蜍进入和生活在沙漠主要是依赖于大沙鼠的洞穴潮湿,并捕食洞中的各种蝇虫.

古尔班通古特沙漠南缘固定沙丘上土壤水分与地形-植被因子的关系
Shuitu Baochi Xuebao, 2023 土壤水分是干旱和半干旱生态系统格局和过程的主要驱动力,地形-植被因子是小尺度上影响土壤水分的主要因子。以古尔班通古特沙漠南缘北沙窝附近固定沙丘上不同深度的土壤水分(表层0-40 cm、中层40-200 cm、深层200-300 cm和整体0-300 cm)作为研究对象,利用广义线性模型(GLM)、广义加性模型(GAM)和随机森林(RF)模型研究了土壤水分与地形-植被因子之间的关系和变化规律。结果表明:(1)不同深度的土壤水分均呈现一致的单峰分布,不同深度土壤水分的大小顺序为深层>中层>表层 ...
