“…This was a satisfactory result, attributed to the maximum possible calibration (Table 3). The result confirmed the results obtained by Mitchel et al (1993), Perrone andMadrammooto (1997), andBhuyan et al (2003) in Illinois, Quebec, and Kansas watersheds, respectively, that AGNPS simulates runoff with reasonable accuracy. The model prediction for runoff was much better than obtained by Nigussie and Fekadu (2003), Hassen et al (2004), andLen et al (2004) in the Augucho catchment, Kori watershed, and a southern Ontario watershed, respectively.…”

“…The increases in nutrient losses and riverine nutrient loads have caused the eutrophication of many coastal and freshwater ecosystems (Nixon et al, 1995;Vitousek et al, 1997;Carpenter et al, 1998). A watershed protection approach is an important strategy to effectively protect a watershed and thereby restore aquatic ecosystems and protect human health (Bhuyan et al, 2003).…”

“…As a very practical tool, it has been proved to be very effective in many regions including southeastern China (Cao et al, 2002;Hassen et al, 2004;León et al, 2004). This model was also suitable for interfacing with GIS (Geographical Information System) to expedite data input and display/interpret model results (Bhuyan et al, 2003;He, 2003). AGNPS was intended to provide watershed managers with a tool that would enable them to design and target BMPs effective in improving water quality conditions in rural watersheds (León et al, 2004).…”

This study tested and evaluated the agricultural non-point source (AGNPS) model for the Wuchuan catchment, a typical agricultural area in the Jiulong River watershed, Fujian Province, China. The AGNPS model was calibrated and validated for the study area with observed data on ten storms. The data on eight storms in 2002 were used for calibration while data on two storms were used for validation of the model. Considering the lack of water quality data over a long-term series, a novel method, comparing an internal nested catchment with its surrounding catchment, was used to supplement the less long-term series data. Dual calibration and validation of the AGNPS model was obtained by this comparison. The results indicate that the correlation coefficients were 0.99 and 0.98 for runoff, 0.94 and 0.95 for the peak runoff rate of the large catchment and the small catchment, respectively, and 0.76 for the sediment of the small catchment only. Each pair of correlation coefficients is homogeneous for the same event for the two catchments. With the exception of the sediment yield and particulate phosphorus, the peak runoff rate and other nutrients were well predicted. Sensitivity analysis showed that the Soil Conservation Service curve number and rainfall quantity were the most sensitive parameters, which resulted in high output variations. Erosivity and other parameters had little influence on the hydrological and quality outputs.

Agricultural decision-making to control nonpoint source (NPS) water pollution may not be efficiently implemented, if there is no appropriate cost-benefit analysis on agricultural management practices. This paper presents an interval-fuzzy linear programming (IFLP) model to deal with the trade-off between agricultural revenue, NPS pollution control, and alternative practices through land adjustment for Wuchuan catchment, a typical agricultural area in Jiulong River watershed, Fujian Province of China. From the results, the lower combination of practice 1, practice 2, practice 3, and practice 7 with the land area of 12.6, 5.2, 145.2, and 85.3 hm 2 , respectively, could reduce NPS pollution load by 10 %. The combination yields an income of 98,580 Chinese Yuan/a. If the pollution reduction is 15 %, the higher combination need practice 1, practice 2, practice 3, practice 5, and practice 7 with the land area of 54.4, 23.6, 18.0, 6.3, and 85.3 hm 2 , respectively. The income of this combination is 915,170 Chinese Yuan/a. The sensitivity analysis of IFLP indicates that the cost-effective practices are ranked as follows: practice 7 > practice 2 > practice 1 > practice 5 > practice 3 > practice 6 > practice 4. In addition, the uncertainties in the agriculture NPS pollution control system could be effectively quantified by the IFLP model. Furthermore, to accomplish a reasonable and applicable project of land-use adjustment, decisionmakers could also integrate above solutions with their own experience and other information.

“…This paper seeks to determine the severity of the level of air pollutants from Fuxin colliery and the extent of temporal and spatial variations of all individual pollutants over a 1-year period. For air quality assessment, index assessment is the method used by most researchers (Rossbach et al 1999;Bhuyan et al 2003). one simple and well known method developed by the environmental Protection Agency includes the air quality index (AQi) (onkal-engin et al 2004).…”

An extension of the matter-element method was applied to estimate ambient air quality in Haizhou opencast colliery in Fuxin coal mine. Air pollutants data such as sulphur dioxide, carbon monoxide, nitrogen oxides, total suspended particulates, particulate matter and dustfall were collected at four different air-quality monitoring stations located in four districts around the Fuxin colliery. Results show that total suspended particulates, particulate matter <10 µm, dustfall and sulphur dioxide were the predominant pollutants. Other pollutants such as carbon monoxide and nitrogen oxides were also detected at the Fuxin colliery. Air pollution came mainly from industrial emissions, mining activities and abandoned gangue stockpiles (mine tailings).Compared to those applied to other mathematical assessment methods, it was demonstrated that the extension of the matter-element model was quite appropriate for air quality assessment.
