Relationships between carbon (C) production and nitrogen (N) mineralization were investigated in two alpine wetland soils of the Tibetan Plateau using laboratory incubation under different temperatures (5, 15, 2., and 35 ℃) and water saturation (noninundation and inundation). A significant positive relationship was found between CO2.production and N mineralization under increasing temperatures from 5 to 35 ℃ with the same water saturation condition in the marsh soil (r2.> 0.49, P 2.> 0.38, P 2., and a negative relationship with water saturation increasing at the same temperature, especially 2. and 35 ℃, in the marsh soil (r2.> 0.70, P 2.> 0.61, P 3). In conclusion, temperatures and water saturation could regulate the relationship between CO2.production and net N mineralization in the Tibetan alpine marsh and peat soils.

The paper chose two counties (Qis) in Inner Mongolia as the research areas to study the policies of conversion of farmland to forest and grazing prohibition and indoor raising implemented in there, which are closely related to the interests of farmers and herdsmen. Based on the investigation and interview among farmer households, the paper analyzed the consistency between land degradation prevention and control policy and the needs of farmers and herdsmen, and finally presented the countermeasures and suggestions which are conducive to improving the effectiveness of land degradation prevention and control policy.

This article emphatically reviews the difference of soil biological activities, biochemical activities and soil chemical properties between the rhizosphere and non-rhizosphere soil of first rotation of chinese fir (Cunninghamia lanceolata (Lamb) Hook) plantation. It also reviews their dynamic patterns during chinese fir plantation development. The results show that the contents of organic and inorganic nutrients in the rhizosphere soil of young, half-mature and near-mature chinese fir of first-rotation ...

Using the molecular dynamics method,we have constructed two kink models corresponding to the 〈100〉{010} and 〈100〉{011} edge dislocations (EDs) in body centred cubic (bcc) Fe. It is found that the geometric structure of a kink depends on the type of edge dislocation and the structural energies of the atoms sites in the dislocation core region. The formation energies,migration energies and widths of the kinks in different types of EDs are calculated. The results show that formation and migration of the kink in the 〈100〉{010} edge dislocation are difficult. The 〈100〉{011} edge dislocation moves primarily through kink nucleation,rather than kink migration.

As a country seriously afflicted with desertification, China suffers a large area of desert land. Although desertification has been brought under control in certain areas, the whole situation is still deteriorating, which constitutes a great impediment to the harmonious development of population, resources and environment in the desertification afflicted regions, which play a crucial role in the nation’s social economic development and environmental protection. desertification control is of great importance to narrowing the gap between the east and the west, eradicating poverty and boosting the economic development of the desertification affected regions and the whole country.

To improve and diversify the use of tropical plantation timbers in Southern China, with support from International Tropical Timber Organizations (ITTO), a research project was started in 2.02.focusing on development of processing and manufacturing technologies to promote production of value-added wood products from eucalypts plantations. This project will also facilitate the formulation of forest management strategy in China to supplement the diminishing supply of timber from the natural forests. The sp...
