Northeast China is one of the most important regions for food production in China, with its cropping system being significantly affected by the climate change and vulnerable with water and heat stress. For annual harvest in Northeast China, agricultural precipitation and thermal resources were the primary environmental factors for crops growth from May to September. Therefore, its temporal and spatial change, distribution and use efficiency become important to the crops growth. We choose annual mean precipitation (AP) and annual accumulated temperature 10°C (AAT10) in the growing season to represent the water and thermal resources. And we use Agricultural Precipitation Resources Use Efficiency (APUE) and Agricultural Thermal Resources Use Efficiency (ATUE) to reflect the water and heat utilization. The results showed that 1) AAT10 increased slightly from 1971 to 2006 with distribution of decreased from southwest to northeast, AP trends was decreased and with regional variation that concentrated on the southeast of Northeast China, 2) APUE was 6.6-6.8 kg/mm · hm2 higher than the national level (5.25 kg/mm · hm2) and lower than the world level (7-7.8 kg/mm · hm2). ATUE was 1.13-1.72 kg/hm2 · d · °C, which was higher than the national level, 3) Annual mean precipitation and thermal resources use efficiency in growing season was not distribute as the natural resources distributed which meant the potential of water and heat use was not insufficient. We propose the potential resources measures as follows: 1) Prevented chilling damage and be fit for the temperature increased and make water conservation, 2) Choosing systematic irrigation management measures according to water spatial and temporal allocated changed, 3) Improving the multiply cold and arid tolerance varieties technology and adjusting crops planting structure and varieties distribution to adapt climate change impacts.

Biogeochemistry characteristics of an unsaturated zone in Jinghuiqu irrigation district of China was studied to analyze the predominant interacting factors of nitrogen concentration and transformation in the vadose zone under long term flood irrigation using river water and groundwater sources alternatively. The site was instrumented for soil sampling at various depths above the groundwater table at 4 meters below the soil surface. The measured concentrations of the biogeochemicals (TN, N-NO3-, N-NH4+, and several microorganisms) showed that there exist “active” and “inactive” layers in the profile, which were distinguished by the combined amount of clay and silt particles in the soil. Most parameter values increase sharply in the “active” layers and decrease sharply in the “inactive” layers. In the active zone, the N-NO3- was concentrated and more transformed by microorganisms. All the N concentrations, in NNO3-, N-NH4+ and TN, were mainly affected by the amounts of organic matter and microorganisms.

Artificial aquifer recharge is an important measure to raise the groundwater level, prevent and remedy the environmental and geological problems caused by the over extraction. Because of the physical and chemical clogging, the performance of recharge decreased gradually and the hydraulic conductivity reduced during the recharging process. In order to reveal the changing of recharging performance, the paper took the single injection well recharge as an example to research the changing law of hydraulic conductivity. The recharge test with pressure was done in confined aquifer depth of 100 to 300m at the south suburbs of Xi'an. The results show that hydraulic conductivity of artificial aquifer recharge attenuated with time power function and was smaller than the hydraulic conductivity of pumping. When the quantity of water recharge per unit time was smaller, the attenuation of hydraulic conductivity was slower. The performance of small quantity of water recharge per unit time was better than the large.

Since the late of 20th Century, economy and society have rapidly developed in Jinfo Mt. region, which led to serious nitrite pollution of groundwater in this region. In recent years, some environmental policy measures have been implemented. These environmental policy measures made the use of chemical fertilizer in agriculture in the region reduce much. Since 2004 to d2009 the nitrate pollution of groundwater in Jinfo Mt. region had been reduced significantly. The environmental policy measures implemented in this region were very successful, the effects of which to environmental protection is positive.

The iron and steel industry, as the largest energy consuming industry in China, is as well as one of the most important sources of CO2 emissions and other pollutants. To improve the emission reduction and energy saving for Chinese iron and steel industries, an integrated steel plant combined with a series of advanced energy saving technologies was proposed in this study. The economic and emission reduction potential assessment was carried out for each technology. After calculations and analysis, the proposed technologies were then evaluated from the technical, environmental, and economic aspects, respectively and significant results were obtained.

This paper collects and summaries the existing materials, taking the field obersavations. The evapotranspiration in Ge'ermu area is estimated by combining hydrologic data and the remote sensing data, and the law of evapotranspiration distribution variation in study area was obtained statistically. So as to analyse the factors of influencing evapotranspiration. The result showed that many crucial physical factors, such as the energy supplying condition, the vapor transportation condition, and the ability of evaporation media to supply water influenced evapotranspiration in the process. Solar radiation may be the main energy supplying, saturation deficit and wind velocity will also decide the vapor transportation condition, moreover, the ability of evaporation media to supply water is depended on groundwater, the soil constitution and surface vegetation. The main factors influenced evapotranspiration in arid areas Climate conditions were the depth of groundwater table, the lithology of vadose zone, the rate of vegetation covering and so on.

This paper identifies the determinants which affect the environmental disclosure of company in China from a comprehensive perspective of public pressure and stakeholder management. Environmental disclosure data are collected from the annual reports of year 2008 which includes 200 firms from 21 industries. Both quantity assessment and quality assessment are employed to measure the level of environmental disclosure. Results show that there are significantly positive associations between the level of environmental disclosure industry types, firm size and state blockholder. The findings suggest that company characteristics such as size and industry are the antecedents of public pressure which drives the company to respond to rather than by impetus of profitability.

Absence of soil phosphorus constrained the crop yield, the use of limited water resource and nitrogen nutrient in dryland on the loess plateau. Reasonable phosphorus fertilization was also crucial to increase crop yield and improve water and nitrogen use efficiency. It was conducted that the effect of phosphorus application rate on crop yield, water consumption, nitrogen absorption, water use efficiency, and nitrogen use efficiency at long term fertilization experiment station in dryland on the loess plateau during different precipitation year. The results showed that during different type of year most of the indexes had similar trend of rising with phosphorus rate increasing in a lower range and dropping down in a higher range except for water consumption and harvesting index (HI). More higher phosphorus rates were unfavorable to crop yield, water and nitrogen use efficiency in both types of years but phosphorus application in all rates decreased HI and water consumption more than non phosphorus application treatment in dry year. So moderate phosphorus application was the favorable selection for higher crop productivity, water and nitrogen use efficiency in dryland on loess plateau, simultaneously may be helpful for improving utilization effect of phosphorus fertilizer.
