Abstract

The aim of this study was to determine the effect of different sized aggregates on runoff, sediment by runoff, and by splash with simulated rainfall. A soil sample which is known and well aggregated, was taken from the Agriculture Faculty’s Research Field of Ege University, and passed through different sieves (25-20 mm, 20-16 mm, 16-10 mm, 10-5 mm, 5-2 mm, 2-1 mm, and 1-0.2 mm) to establish 7 grouping. The sieved soil samples were placed in the erosion trays (30x30 cm), and simulated rainfall (65 mm h-1) was applied to the trays for 1 hour. According to the results of the simulated rainfall experiments, the aggregate sizes were found very effective on runoff (p= 0.0001; r= -0.420**), sediment by runoff (p= 0.0001; r= -0.980**), water resistance aggregate stability (p = 0.0001; r= 0.840**), mean weight diameter (p= 0.041; r= 0.550*), and aggregate index (p= 0.0001; r= 0.867**), significantly. No correlation was found between the aggregate sizes and sediment by splash linearly but polynomial relationships were found between the aggregate sizes and sediment by splash in the study.

模拟降雨条件下骨料粒径对径流和飞溅侵蚀影响的研究。

本研究的目的是确定不同大小的团聚体对径流、径流泥沙和模拟降雨的影响。从埃格大学农业学院研究领域采集了已知且聚集良好的土壤样本，并通过不同的筛子(25-20 mm, 20-16 mm, 16-10 mm, 10-5 mm, 5-2 mm, 2-1 mm和1-0.2 mm)建立7组。将筛过的土壤样品置于侵蚀盘(30x30 cm)中，模拟降雨(65 mm h-1) 1小时。根据模拟降雨实验的结果，发现团聚体对径流非常有效(p= 0.0001;R = -0.420**)，径流泥沙(p= 0.0001;R = -0.980**)，耐水骨料稳定性(p = 0.0001;R = 0.840**)，平均体重直径(p= 0.041;R = 0.550*)，综合指数(p= 0.0001;R = 0.867**)，差异有统计学意义。研究发现，泥沙粒径与水溅泥沙之间不存在线性相关关系，但二者之间存在多项式关系。

期刊介绍： Cessation. Ekoloji is an international journal that focuses on papers that report results from original research on all disciplines engaged in the field of environmental research. We welcome articles that cover the entire spectrum of environmental problems and environmental pollutants, whether chemical, biological or physical. Its coverage extends to all environmentally related issues: air and water pollution, solid waste, noise, recycling, natural resources, ecology and environmental protection. It includes articles on basic and applied environmental pollution research, including environmental engineering and environmental health. All types of pollution are covered, including atmospheric pollutants, detergents, fertilizers, industrial effluents, metals, mining wastes, oil, pesticides, plastics, radioactive materials and sewage. It also includes research papers on ecological and environmental issues such as climate change, biodiversity. The primary criteria for publication are scientific quality and ecological/environmental significance. The journal will be read and contributed to by biologists, applied ecologists, environmental scientists, natural resource specialists, environmental engineers, environmental health specialists, agro-ecologists, veterinaries, agricultural engineers, landscape planners and designers. The journal welcomes full "research papers" and short "research notes", only in the English language.
