Afforestation plays an important role in soil protection and ecological restoration. The objective of this study is to understand the effect of afforestation on soil carbon and soil microbial communities in the Loess Plateau of China. We measured two chemically-separated carbon fractions (i.e., humic acid, HA, and fulvic acid, FA) and soil microbial communities within shrublands (18-year-old Ca...
Afforestation is a mitigation option to reduce the increased atmospheric carbon dioxide levels as well as the predicted high possibility of climate change. In this paper, vegetation survey data, statistical database, National Forest Resource Inventory database, and allometric equations were used to estimate carbon density (carbon mass per hectare) and carbon storage, and identify the size and s...
Afforestation is an approach for ecological restoration. Soil total phosphorus one of the important and evolutionary elements carbon cycles plant growth following afforestation. However, studies on soil afforestation abandoned ponds with different slopes are still lacking. other properties from sites were investigated. phosphorus, nitrogen, bulk density, water contents pH poplar ( Populus spp.)...
Afforestation of marginal land has been recommended by the Intergovernmental Panel on Climate Change (IPCC) as a means enhancing capacity soil to act carbon (C) sink. However, success this practice is variable and depends many factors, including type management used. In study, we quantified compared C stocks in two highly productive agricultural soils afforested with poplar 10 years before stud...
Afforestation is an important and effective way to curb wind-sand hazards in the Alxa Desert. However, over-afforestation makes soil drying occur frequently. The formation of a layer seriously restricting effectiveness vegetation construction regional ecological stability. To clarify process desiccation Haloxylon ammodendron plantations determine suitable planting years, typical H. plantation t...
