Abstract
Wildfires cause an increase in runoff and erosion due to the destruction of vegetative cover and alteration of soil characteristics. This study was carried out to determine the impacts of the forest fire, the runoff and erosion, which occurred on 18 August 2011 in the Village of Doganci, a village of the city of Bayramic located southeast of Canakkale. A total of 12 rainfall simulations were performed on the adjacent burned and unburned lands. Simulations were carried out during the initial month after the fire under very low soil moisture conditions. The parameters: time to runoff, mean runoff, maximum runoff rate, runoff percentage, sediment concentration, peak of sediment, and total soil loss were measured for each simulation. The data was compared using an independent t-test. The difference in time to runoff values between the burned and unburned cases was found to be significant at p<0.01 level. The runoff and maximum runoff values of the burned plots were found to be respectively 15 and 16 times higher than the unburned plots. While the runoff percentage was 7.66% for the burned plots, it was determined as 0.51% for the unburned plots. Sediment concentration and the peak of sediment for burned plots were found to be 7.70 g L-1 and 14.67 g L-1, respectively, and the values for the unburned plots were observed as
由于植被覆盖的破坏和土壤特征的改变，野火造成径流和侵蚀的增加。开展这项研究是为了确定2011年8月18日发生在恰纳卡莱东南部Bayramic市的一个村庄Doganci村的森林火灾、径流和侵蚀的影响。在相邻的烧地和未烧地共进行了12次降雨模拟。模拟是在火灾后的第一个月，在非常低的土壤湿度条件下进行的。每次模拟均测量了径流时间、平均径流量、最大径流量、径流量百分比、含沙量、含沙量峰值和土壤总流失量。数据比较采用独立t检验。在p<0.01的水平上，燃烧和未燃烧情况下的时间与径流值差异显著。燃烧样地径流量和最大径流量分别是未燃烧样地的15倍和16倍。燃烧样地径流量为7.66%，未燃烧样地径流量为0.51%。燃烧样地的含沙量为7.70 g L-1，沉积物峰值为14.67 g L-1，未燃烧样地的含沙量为
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.
