The Northeast shelterbelt project is a part of the Shelter Forest System Program in Three-North Regions of China. By far, the third phase project has been completed, and the fourth phase project is on the point of completion. This paper chose the Yushu, Nong'an, Dehui and Fuyu in midwestern Jilin province as the research areas, selected three phase shelterbelt data and land use data at Sep. 25, 1988,...
Spatial variations of pH value in three horizontal soils in Guangdong, China, were surveyed and analyzed using geostatisitic and GIS. A total of 260 soil profiles data followed an approximately lognormal distribution. The pH value geometric mean of 5.12 in surface soils is lower than that in global soils with higher acidity. From A- to C-horizon pH value geometric mean had an increasing tendency of...
A wide range of numerical models and tools have been developed over the last decades to support the decision making process in environmental applications, ranging from physical models to a variety of statistically-based methods. In this study, a landslide susceptibility map of a part of Three Gorges Reservoir region of China was produced, employing binary logistic regression analyses. The available...
