The variations of Baltic Dry Index (BDI) and Shanghai Stock Exchange Composite Index (SSE Composite Index) over the last three years reflected the historical features of the world economy in financial crisis. In order to test the correlation of BDI and SSE Composite Index, the weekly average data of BDI and SSE Composite Index from 2007 to 2009 are taken as empirical sample data by statistical analyzing...
Haloxylon ammodendron is constructive species, which had degeneration in large areas in the western part of Gurbantonggut Desert, the second largest desert of China. Therefore, we investigated the spatial distribution of dead plants, the age structure of both live and dead plants in the population, the depth of groundwater and soil quality. The results showed that: (1) the dead plants of H. ammodendron...
Topography is one of major factors influencing soil properties at the landscape scale, especially in hilly areas. Derived terrain attributes based on digital elevation models (DEMs) may be used for soil spatial distribution prediction. Accurate estimate of spatial variability of soil organic matter (SOM) is critical to evaluate soil quality as well as assess the C sequestration potential. However,...
