A WRF based numerical weather prediction model is set up to forecast the local meteorological parameters and estimate cloud base heights information. The cloud base height estimation is adopted to derive real locations and sizes of clouds, and eventually obtain very-short term forecast of the local global horizontal irradiance. The validation of the proposed method is carried out by comparing predicted and measured irradiance of a test site. The results show that the method has high prediction accuracy, and has ability to predict the radiation fluctuation caused by the cloud sheltering process.

Beijing is now facing the intense water shortage problem. Evaluation of regional water resources capacity provides a scientific basis for further water resources utilization and social economic sustainable development. This study mainly focused on assessing the water resource carrying capacity in Beijing during the period from 1980 to 2011. The results indicated that the domestic and environmental water resource ecological footprint showed increasing trend, whereas agricultural and industrial water resource ecological footprint showed decreasing trend. The total water resource ecological footprint increased from 6.5×106 hm2 in 2011 to 6.8×106 hm2 in 2015 and 9.1×106 hm2 in 2020, respectively. Even taking the South-to North water transfer project, the water supply still not meet the serious water demand in Beijing with 10×108 hm3 of water shortage in 2020. Moreover, policies for reducing the water resource ecological footprint and increasing the water resource carrying capacity were put forward.

Through the current situation survey of geological environmental disasters caused by limestone mining in Chongqing and combined with the principles of establishing evaluation index system and industry experts’ advices, we get the geological environmental impact assessment system of open-pit limestone mining which is consist of 7 dimensions and 25 indexes. Using analytic hierarchy process (AHP) to assign the weight of 25 indexes and based on membership functions of trapezoidal distribution to establish evaluation standard, the fuzzy comprehensive evaluation model is constructed. According to the principle of maximum membership degree, we get the influence degree of the geological environmental system affected by the open-pit limestone mining in Chongqing. This model makes the impact on geological environment of limestone mining quantitative and plays a certain guiding role in the local environmental protection strategy formulation and geological disaster prevention.

The Cu2O/TiO2heterostructure nanocomposites photocatalysts with different molar ratios of Cu2+/Ti4+were successfully synthesized by a simple hydrothermal procedure. The obtained samples were characterized by XRD, SEM, UV-vis DRS in order to detect the composition, the shape and the property. The photocatalytic activity of Cu2O/TiO2nanocomposites was evaluated by the degradation of methyl orange (MO) as a model compound. The experimental results showed that the prepared Cu2O/TiO2nanocomposites exhibited higher photocatalytic activity for the degradation of MO than the pure Cu2O and the commercial anatase TiO2under visible light irradiation.

Single factor water quality identification index (SFWQII) and Comprehensive water quality identification index (CWQII) were applied to the data of 6 parameters for water quality of West Lake at 10 different sites and 4 main inflows in the West Lake basin, generated during March 2012 to February 2013. This study evaluated and elucidated the temporal and spatial variation of each parameter on water quality and the main pollution factor of West Lake by SFQII. CWQII based on the SFQII was applied to evaluate the eutrophication level of West Lake and substantiated mesotrophic waters. Stable isotopes of nitrate were used to identify the nitrate sources of West Lake. The δ15NNO3 values in samples from the West Lake and inflows had a range of 2.6‰ to 12.0‰, while the δ15NNO3 values in Qiantang River was 5.3‰, in rainfall was 5.2‰ and in runoff was 3.6‰, respectively. Animal wastes, commercial fertilizer and domestic sewage were the main nitrate sources. The groundwater and denitrification might increase the levels of NO3- in West Lake.

Published: December 2014

The climatic characteristics of haze and pollutants were analyzed based on surface observations obtained from Meteorological Observation Station and Environmental Monitoring Center Station from January, 2013 to March, 2014 in Wuhan. The high frequency of haze in Wuhan was from September to December, with following trend “winter>autumn>spring>summer”. According to the manual observation, haze occurrence at 11:00 was highest. The value of Air Quality Index (AQI) was highest in January and December. The primary pollutant in Wuhan was PM2.5, secondly O3. Horizontal diffusion played an important role in concentration of pollutants. The highest concentration of PM2.5 converged around wind from north or east.
