Planting vegetation to restore the soil environment is one of the most important methods for combating desertification. Reasonable vegetation type and vegetation coverage has an important role in sand control and the regional ecological security. The objective of this study is to clarify the appropriate type and coverage of sand-fixing vegetation in the Mu Us Desert. We identified changes in t ...

The Chinese Government wants to develop mixed stands with complex structures, particularly in monoculture forest areas. However, despite the enthusiasm for planting trees, is sufficient thought being given to the development of forestry objectives? A logical alternative would seem to describe the structure of such mixed stands through the use of specific-model management tools. This paper conc ...

The impact of the soil and water conservation measures in the process of river runoff and sediment discharge has caused wide attention. The Wei River, which has a serious water shortage and a high sediment concentration, was selected as the research watershed. Based on the measured data of rainfall, runoff and sediment, the statistical methods of wavelet analysis, Mann-Kendall test, and double ...

Natural regeneration of Korean pine (Pinus koraiensis Siebold & Zucc.) in northeastern China has often been problematic in mixed broad-leaved Korean pine forests (primary forest), but not in deciduous broad-leaved forests (secondary forest). Light transmittance, soil temperature, leaf area index (LAI), height and diameter of Korean pines were estimated in order to examine the contribution of c ...

Regional logistics with a large quantity of energy consumption and carbon emissions has great important impacts on the regional ecological environment. Therefore, constructing the regional logistics ecosystem has become a crucial way to minimize the environmental impacts. This paper aims to accurately obtain the characteristics and causes of carbon dioxide (CO2) emissions of regional logistics ...

It has been observed that water in the reservoirs has a trend towards eutrophication even under natural environment, while human activity makes the situation worse. Studies on eutrophication are mainly focused on nutritive salt control. It is an effective method to remove the nutrient substance by using attached algae

Variations in different characters of the pigeonpea were studied using 122 accessions under rainfed condition during 2013. The characters considered viz., days to 50 per cent flowering, plant height (cm), days to physiological maturity, pods per plant, pod bearing length (cm), seeds per pod, 100 seed weight (g) and seed yield per plant (g) were used for the analysis. K-means cluster analysis w ...

Parametric data from anaerobic digestion processes are normally collected once every couple of days and not daily. As a result, only a small amount of data could be collected and this is not sufficient for the neural network analysis. In this research, interpolations were used during the modelling process to increase the sample data used for Elman neural network (Elman NN) modelling. Laborator ...
