And NaNO3 was used as nitrogen salt, KCL as potassium salt, and CuSO4 · 5H2O provided Cu2+. Different concentrations of nitrogen and potassium salt were prepared to carry adsorption reaction with certain concentration of Cu2+ in aqueous solution. Through these experiments, study that whether a competitive adsorption occurs between nitrogen, potassium nutrients and Cu2+ or not, as well as the variation of adsorption rate of Cu2+ in different concentrations of nitrogen and potassium nutrients. The study results show that: (1) NO3- affects the adsorption rate of Cu2+. As the concentration of NO3- increases, the adsorption rate of Cu2+ decreases. When the concentration of NO3- is larger than a certain value, the adsorption rate of Cu2+ will increase gradually. (2) There is competitive adsorption between K+ and Cu2+, with the increase of concentration of K+, the adsorption rate of Cu2+ decreases gradually.","PeriodicalId":6425,"journal":{"name":"2011 International Symposium on Water Resource and Environmental Protection","volume":"8 1","pages":"3150-3152"},"PeriodicalIF":0.0,"publicationDate":"2011-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84732693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the AGNSP characteristic, the AGNSP model was divided into “Sources” module and “Sinks” module. Thereinto, “Sources” Module is further divided into farmland irrigation drainage sub-module and contaminants concentrations in farmland drainage estimating sub-module, in which, irrigation drainage was calculated by DRAINMOD model based on the principle of water balance on farmland. Meanwhile, the synthesis of fertilization and irrigation is used as an impulse input to the farmland, the pollutant concentration change in agricultural drainage is looked as the response process corresponding to the impulse input, the complex migration and transformation process of pollutant in soil is expressed impliedly by Inverse Gaussian Probability Density Function. The one-dimensional transport model of AGNSP pollutants in drainage ditch system was constructed on the basis of the equation of continuity of flow and pollutants migration and transformation. Integrating two modules, the complete AGNSP load model was constructed.","PeriodicalId":6425,"journal":{"name":"2011 International Symposium on Water Resource and Environmental Protection","volume":"2 1","pages":"1636-1639"},"PeriodicalIF":0.0,"publicationDate":"2011-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79577579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the Geographic Information System (GIS) technology and the Integrated Valuation of Ecosystem Services and Tradeoffs Tool (InVEST) model were applied to estimate the amount of soil loss and assess the soil conservation capacity by the main ecological system in the Upper Yangtze River Basin (UYRB). The results show: (1) the annual potential soil erosion is 92.92×108 t year-1. The area of average annual soil loss bellow 500 km-2 year-1 occupies 35.08% and above 5000 km-2 year-1 occupies 36.8%.

Based on the principle of pair-copula decomposition, An example of applying the copula to multivariate hydrological drought frequency was given. Monthly average flow data from Zhuang tou gauging station in Weihe Basin, China, was used to illustrate these methods. Chi-square test, Kolmogorov-Smirnov test, Cramer-von Mises statistic, Anderson-Darling statistic, modified weighted Watson statistic, and Liao and Shimokawa statistic were employed to test goodness-of-fit for these univariate distribution. Pearson's classical correlation coefficient rn, Spearman's ρn, Kendall's τ, Chi-Plots, and K-Plots were used to assess the dependence of drought variables. According to three different permuting ways of drought variables, twelve copulas were used to model the joint probability distributions. A three dimensional probability distribution formula was derived. Based on the Root Mean Square Error (RMSE), the Akaike Information Criterion (AIC) and Bayesian Information Criterial (BIC), the best fitting copula was selected. A bootstrap version based on Rosenblatt's transformation was employed to test the goodness-of-fit of the copula. Comparing with 12 copulas, the Frank copula under D-V-P structure has the best fitting for joint probability distribution of hydrological drought distribution. The results indicated pair-copula decomposition is a feasible way to model multivariate frequency analysis.","PeriodicalId":6425,"journal":{"name":"2011 International Symposium on Water Resource and Environmental Protection","volume":"67 1","pages":"2635-2638"},"PeriodicalIF":0.0,"publicationDate":"2011-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90733808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
