The carbon sequestration dynamics can be used to assess the ecological effects of an ecological restoration project. Here, we conducted vegetation and soil study to assess the carbon sequestration in the plantations with 10 years old stands in Beijing-Tianjin sand source areas. The results at the site scales indicated that the average net increase of plantation ecosystem carbon stock was 33.8 Mg C ha^(-1), with an annual increase rate of 3.38 Mg C ha^(-1) yr^(-1). The average net increase of carbon varied among regions, vegetation types, and forest management activities. Soil bulk density in the top soil decreased slightly after 10-year implementation of the project. Coniferous forests and shrubs are suitable plant species for sand source areas.Natural restoration in the plantations is a practical and feasible and promising approach for enhancing ecosystem carbon sequestration potential.展开更多

Examples of ecosystems include the tropical rainforest ecology, marine ecology of the coastal forests, and the estuary type ecology of mangrove forests. The Jhong-Dou Wetland Park is situated in the Jhong-Dou Redevelopment Zone, 2.5km from the Lover River Estuary. This area is defined by brackish aquatic environments--a mixture of fresh and salt water, and fulfills the criteria for mangrove restoration. It is expected that the current restoration project will recreate an epitome of the once-diverse, co-existing mangrove species of Kaohsiung＇s past, and improves upon the functions of environmental education. The initial mangrove species planned for restoration are the existing Kandelia obovata, Rhizophora stylosa, Avicennia marina and the Lumnitzera racemosa populations of the Kaohsiung area. These plants will be placed in experimental habitats that correspond to the unique micro-climates required for the growth of each species, and the mangrove-associated plants will also be restored concurrently in the terrestrial environments behind the mangrove forests. The process of restoration will be monitored by academia, as well as providing reference for subsequent mangrove environment restoration efforts. The main purpose of this research in these four mangrove species of this wetland park is to understand their adaptation to the rehabilitating environment, and be able to feedback these information to the design and maintenance team of the park. The research method is to observe and record their growing status, also execute a survey on the nearby mangrove habitation. The observation has started on December 1 st of 2010, and still has been continued carry on since then. From the research result, it shows that the A vicennia marina （Forsk.） Vierh. and Lumnitzera racemosa Willd. are the two species that had been well adapted to this wetland park. It was recommended to the Kaohsiung City Government that the restoration of the extinct Ceriops tagal and Bruguiera gymnorrhiza can be achieved through foreign species exchanges （the species must be identified before introduction）, and that plans for monitoring the flora and fauna in the park should be drafted to record the ecological alterations of the Jhong-Dou Wetlands. This will pronounce the ecological importance of Kaohsiung on a global, geographical scale. Lastly, the Government should draw up plans of mangrove forest maintenance in order to sustain the ecological and landscape recreational functions of the Jhong-Dou Wetland Park.展开更多
