Effects of Tree Shading on Carbon Fluxes in Artificial Grassland Ecosystems
摘要
Abstract
Two grassland ecosystems,one with tree shading and the other without,in the Qishan Campus of Fujian Normal University were selected as the research objects,and the carbon flux components and related influencing factors of the two ecosystems were measured.The results showed that tree shading significantly increased the net ecosystem exchange and gross primary productivity of the artificial grassland ecosystem(P<0.05),and significantly reduced the ecosystem respiration and soil respiration of the artificial grassland ecosystem(P<0.05).The most important factor affecting the carbon flux of the artificial grassland ecosystem was soil pH,followed by soil volumetric water content and underground biomass.In conclusion,appropriate tree shading can enhance the car-bon exchange and ecosystem productivity of the artificial green space ecosystem in this area,and soil pH regulation can help enhance the sustainable development and carbon sink benefits of the grassland ecosystem.The research results can provide a reference for the sustainable development and management of artificial grassland ecosystems.关键词
