Diversity and species composition of carabid beetles were investigated at Quzhou county in the North China Plain. The study area was originally affected by high salinity and desalinized in three stages in 1973, 1978 and 1982. At sites desalinized in 1982, carabids were sampled at field margins as well as inside fields to investigate the role of field margins as refuge habitats. Furthermore, sam...

Soil salinization is an important factor contributing to the deterioration of soil environment and low crop yield in arable land. In this study, effects five fulvic acid applications (0 (CK), 150 (T1), 300 (T2), 450 (T3), 600 (T4) kg·ha−1) on physicochemical properties, humus content each component, cotton (Xinluzao No. 82) growth were investigated. It was confirmed that improved water-stable m...

With the increasing shortage of water resources, current management saline–alkali lands in semi-arid and arid areas has gradually transformed from “flooding irrigation with drainage” past to combination controlling regional salt balance, phytoremediation, comprehensive utilization halophyte resources. However, soil salinization caused by natural anthropogenic factors still been a major global e...

Saltwater intrusion and upconing phenomena affect coastal aquifers worldwide. Over-exploitation leads to high salinity levels which threaten sustainable use of these freshwater resources. There is an increasing need to accurately, and practically, model the physics of these coastal pumping systems while also incorporating the relevant economics. We formalize a decision model able to define the ...
