摘要

本研究的目的是研究土耳其东地中海地区两种不同母质(砾岩和泥灰岩)上生长的白角松(Fabaceae)和松果松(Pinus pinea)土壤的C和N矿化。碳(C)矿化用CO2呼吸法在28°C下测量30天。在控制条件(42 d, 28°C, 80%田间容量)下，测定了杉木和松木两种母质土壤的体外氮矿化。除2012年7月外，Ceratonia和Pinus两种母材的碳矿化率(%)在所有采样期均存在显著差异。这些结果可能与不同母本材料和植物的影响有关。培养时间与培养时间×株之间的交互作用显著(P= 0.007和P= 0.001)。所有土壤NO3-N含量均高于NH4- N。由此可以解释，两种土壤中环境因子对NO3-N的释放都非常适合于两种松木，尤其是角松木的微生物活动。

Influence of Two Different Parent Materials and Plants on Soil Carbon and Nitrogen Mineralization in a Mediterranean Climate

The aim of this study is to investigate C and N mineralization of soils with Ceratonia siliqua (Fabaceae) and Pinus pinea (Pinaceae) growing on two different parent materials derived from conglomerate and marl in the Eastern Mediterranean Region of Turkey. Carbon (C) mineralization was measured with the CO2 respiration method at 28°C over 30 days. The nitrogen (N) mineralization was also measured in vitro both in the soils with the two parent materials of Ceratonia and Pinus under controlled conditions (42 days, 28°C and 80% of field capacity). There were significant differences between the two parent materials for both Ceratonia and Pinus in terms of the carbon mineralization ratio (%) in all sampling periods except for July 2012 for Ceratonia. These results might be clarified with the effects of different parent materials and plants. Interactions between incubation time, incubation time × plant were significant (P= 0.007 and P= 0.001 levels), respectively for the microbial respiration. The contents of NO3-N were higher than those of NH4- N in all soils. With these results it might be explained that environmental factors in both soils for NO3-N are quite suitable for the microbial activities of both Pinus and especially Ceratonia.

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.
