چکیده
One quarter of the world’s population uses karst groundwater. Due to complex hydrological conditions in areas, they are vulnerable pollution. The study hydrochemical characteristics and environmental quality evaluations groundwater is great significance for rational development utilization area located Mengzi Yunnan Province, which a typical area. was analyzed evaluated by statistical analysis, hydrogeochemical ion ratio Nemerow’s index method (PN). results show that types mainly Ca–HCO3 Ca–Mg–HCO3 types. main compositions were controlled carbonate dissolution. water evaluation pollutants Mn, COD NO3−. Compared with groundwater, concentration exceeding rate surface much higher than those There possibility pollution infiltration. reveal areas provide theoretical basis

Risk Assessment of Drought, Based on IDM-VFS in the Nanpan River Basin, Yunnan Province, China
A new model for risk assessment of agricultural drought based on information diffusion method and variable fuzzy sets (IDM-VFS) was proposed. In addition, an integrated index system of agricultural drought risk was established. In the proposed model, IDM was employed to calculate the agricultural drought risk level classification standards, and then the VFS was adopted to assess the dangerousne...

Based on analysis of groundwater hydrochemical and isotopic indicators, this article aims to identify the groundwater flow systems in the Yangwu River alluvial fan, in the Xinzhou Basin, China. Groundwater delta(2)H and delta(18)O values indicate that the origin of groundwater is mainly from precipitation, with local evaporative influence. d-excess values lower than 10% in most groundwaters sug...
