The development of distributed generation (DG) has brought new challenges to power networks. One of them that catches extensive attention is the voltage regulation problem of distribution networks caused by DG. Optimal allocation of DG in distribution networks is another well-known problem being...

The Gaussian geostatistical model has been widely used in modeling of spatial data. However, it is challenging to computationally implement this method because it requires the inversion of a large covariance matrix, particularly when there is a large number of observations. This article proposes...

Depending on artificial freezing method applied in subway tunnel construction, a series of stress-controlled cyclic triaxial tests were conducted on freezing–thawing mucky clay to investigate their resilient and plastic strain behavior. In terms of practical engineering, this study focuses on...

Karst is widely distributed in the southwest of China, especially in Guizhou Province. The phenomenon of desertification in these areas is very serious. And soil erosion is the key link in the process of desertification. Through field monitoring, underground soil leakage is derived to the main...

Based on the analysis of the status, characteristics and technological functions of high-efficiency ecological agricultural development in the Yellow river delta, the paper pointed out technological bottlenecks of the high-efficiency ecological agricultural development in the Yellow river delta....

Karst rocky desertification is one of the major ecological and environmental problems that threaten the sustainable development of southwestern China. This study focuses on a case study of the small watershed in Chenqi where karst rocky desertification is particularly severe. This paper...

The authors select six indices of resource endowment, supply scale and structure of agricultural products in assessment area of China, and then use Factor Analysis Method and Geographic Information System (GIS) technology to classify the supply capacity of agricultural products in 140 counties...
