Differential Responses of Net Ecosystem Exchange of Carbon Dioxide to Light and Temperature between Spring and Neap Tides in Subtropical Mangrove Forests

Table 1

Parameters and values using the Landsberg model (see (2) in the text) fitted to the daytime net ecosystem change of CO2 (NEE) based on photosynthetic active radiation (PAR) in 10 months of the year 2010 for the mangrove forest of Zhangjiangkou, Yunxiao, Fujian (FJZZ).
