摘要
Abstract
The research progress of carbon sinks and carbon sources in the turfgrass ecosystem both at home and abroad was reviewed in this paper. In the first part, the paper reviewed three aspects： 1） turf- grass biomass, leaf area index and net primary productivity; 2） dynamic changes of soil organic carbon ac- cumulation in the turfgrass ecosystem; 3） soil respiratory intensity. In the second part, it discussed the main research methods of carbon sinks and carbon sources in the ecosystem. There are two main methods, which are eddy correlation and chamber measurements. Furthermore, in the third part, we summarized different factors affected the dynamics of carbon sinks and carbon sources. The factors could be summed as two aspects, which on the one hand was natural environmental factors, such as photosynthetic active radi- ation, atmospheric temperature, soil moisture content and soil temperature; on the other hand was human factors, including mowing, fertilization and irrigation, etc. In the last part of the paper, it also indicated problems of the present researches and the sides to be improved. This paper thus provides reference information for relevant researches in the future.关键词
