项目摘要
I measured respiration and gross primary productivity in the water during summer and winter period using conventional carbon dioxide system(CO_2 system) parameters and dissolved oxygen(DO) measurements as well as triple oxygen isotope technique in a coral reef, seagrass meadow, and mangrove forest which characterize subtropical and tropical coastal zones. From the results obtained, I revealed that the respiration rate was higher by tens of percent to two-hold in the light compared with in the dark. This indicates that the gross primary production and gross respiration calculated based on CO_2 system and/or DO methods give underestimations on these parameters. The respiration was also higher during summer than winter. But it was revealed that the'' photosynthetic anomaly'' which is used as a basis for calculating gross primary productivity can be incorrect or variable, and that we should further investigate this parameter to be able to calculate the respiration and gross primary production more accurately.
我测量呼吸和总初级生产力在夏季和冬季期间使用常规的二氧化碳系统(CO_2系统)参数和溶解氧(DO)的测量以及三重氧同位素技术在珊瑚礁,海草草甸,和红树林森林的特点,亚热带和热带海岸带。从所获得的结果,我揭示了呼吸速率在光下比在黑暗中高百分之几十到两个保持。这表明,根据CO_2体系和/或DO方法计算的总初级生产力和总呼吸量低估了这些参数。呼吸作用在夏季也高于冬季。但是,据透露,“光合异常”,这是用来作为计算总初级生产力的基础,可以是不正确的或可变的,我们应该进一步研究这个参数,以便能够更准确地计算呼吸和总初级生产力。
