Numeric criteria are crucial for controlling cultural eutrophication and for protecting current and future water quality. Anthropogenic climate change and the modification of land use have the potential to influence the development of nutrient criteria. In this study, stressor-response models, land use-nutrient regression models, and terrestrial ecosystem health states were used to determine the criterion...
A modified GM (1,2) model is proposed to simulate the runoff. Zhoukou and Tanghe station was taken as an example. The results show that the modified model was a means to better understand the significance of runoff variability upon climate change. The influence of the future climate change on hydrological processes was discussed. The runoff in this valley is projected on this basis according to the...
