Spatiotemporal variability of soil nitrous oxide emission and its study methods: A review
摘要
Abstract
Nitrous oxide (N2O) is one of the greenhouse gases with great potential of increasing temperature, and its concentration in atmosphere continues to rise steadily. Terrestrial ecosys-tems, especially agro-ecosystem, are one of the important sources of N2O emission. The soil N2O emission of terrestrial ecosystems not only shows great temporal variability, but also has strong spatial variability. To investigate the spatial variability of soil N2O emission under different land uses is of significance to accurately estimate the soil total N2O emission at regional scale. Based on the comprehensive analysis on the spatial variability of soil N2O emission, this paper expatia-ted the main driving factors of soil N2O emission, such as climate, topography, soil properties, and human activities, and summarized the characteristics of the spatial variability of soil N2O emission of different terrestrial ecosystems and related study methods. It would be necessary to unceasingly improve and develop related methods, and use innovative methods such as wavelets method for studying the spatial variability of soil N2O emission, integrating the temporal dimen-sion. In addition, more attention should be paid to the spatiotemporal variability of soil N2O emission of different land use types, and to the accuracy of the estimation of soil total N2O emission.关键词
