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....

Two types of samples were prepared by electrodeposition and a subsequent annealing procedure. The common softening after annealing was observed for the sample without laminated structure in the two sides. However, as for the other sample that possesses laminated structure in the same area at two...

We developed a versatile solvothermal method to synthesize HP–Cu–BTCs series (HP–Cu–BTC(CTAB), HP–Cu–BTC(N,N), HP–Cu–BTC(SDBS)), by using a cationic surfactant (cetyltrimethylammonium bromide, neutral organic amine and an anionic surfactant as the template, respectively, with...

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...

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...
