[Carbon balance in an interplanting stand in subtropical eroded red soil region, China].

We measured the annual net biomass growth, carbon content of each component and soil heterotrophic respiration in four low-efficiency interplanting patterns, ., stands interplanting , , and in Changting County, Fujian Province, with the aim to analyze the effects of interplanting patterns on carbon storage pattern and carbon balance of low-efficiency stand. The ranges of carbon content in different organs of , , , and were 41.

[Dynamic evaluation and driving forces of ecosystem services in Quanzhou bay estuary wetland, China].

Ecosystem service value (ESV) in 1997, 2005, 2013 and 2015 of Quanzhou Bay estuary wetland was evaluated dynamicly by market value, alternative value and opportunity cost methods, combined with classification of service indicators and deduplicate computing. The main driving forces for the changes of ESV and the pathway and intensity of their actions were identified using stepwise regression and path analysis methods. The results showed that the main ecosystem services of Quanzhou Bay estuary wetland were flood regulation, climate regulation, and food supply, which were directly driven by water supply, mariculture carrying capacity, and gross value of the regional production.

[Adaptability of mangrove Kandelia obovata seedlings to salinity-waterlogging].

A laboratory test on the effects of 12 salinity-waterlogging stresses on the growth of Kandelia obovata seedlings was conducted. Nine growth indexes including seedling height, stem height, basal diameter, node number, leaf number, root biomass, stem biomass, leaf biomass and total biomass were measured. The results showed that salinity and salinity-waterlogging stresses had significant effects on the growth of K.
