目的黄河三角洲作为典型生态脆弱区,其景观生态风险受多重因素影响,表现尤为突出。系统认知景观风险不仅是优化景观格局的基础,更是有效应对生态风险的关键。方法以黄河三角洲典型城市东营市为研究区,构建生态系统服务价值和“胁迫度-脆弱度-韧性”的景观生态受损概率评估框架。采用ESDA和地理探测器模型,从网格尺度探究城市景观生态风险的空间异质性及影响因素。结果1) 东营市景观生态风险平均值为0.15,呈北部东部高、中偏西南低的空间格局。生态系统服务价值约为3 175.99亿元,低于当年GDP ...

目的为揭示呼伦贝尔草原风蚀坑4个典型部位的土壤质地差异和持水能力变化特征。方法将风蚀坑分为边缘区(A区)、沙坑区(B区)、重度积沙区(C区)、轻度覆沙区(D区)4个部位,以天然草地为对照(CK区),对各样地0~200 cm土层土壤粒径、土壤体积质量、田间持水量等指标进行相关性分析和PCA分析。结果1)呼伦贝尔草原风蚀坑0~200 cm土层土壤以中砂为主,不含砾石,平均粒径大小为B区(1.41Φ)>A区(1.48Φ)>C区(1.52Φ)>D区(1.98Φ)>CK区(2.45Φ)。2)

[目的] 为探究干涸湖盆典型地表风蚀过程及盐碱尘暴形成的机理。[方法] 以锡林郭勒盟阿巴嘎旗查干淖尔干涸盐湖为研究对象,从湖心到湖岸根据盐湖地表的动态演化过程选择4种典型地表(结皮地表、破碎地表、活化地表和沙化地表),分析从湖心到湖岸近地表土壤粒度分布特征、风速廓线及输沙规律等。[结果] (1)从湖心向湖岸延伸,地表0—2 cm沉积物颗粒粒配整体呈逐渐变粗的趋势,且以黏粒和粉粒为主;(2)干涸盐湖从湖心到湖岸风速整体呈降低趋势,不同地表的风速廓线基本符合Karman的速度对数分布规律,且拟合效果较好 ...
