The water resources consumption grows continually in Chinese urban areas, and urban water resources crisis is becoming more conspicuous. This situation causes arange of resources and environmental problems. It is urgent to solve the urban water crisis for China sustainable development. Seawater desalination, reclaimed water reuse and storm water utilization are three possible ways to alleviate the urban water resource (resources)crisis. The operating costs comparison shows that storm water utilization is the most economical way than the other two. Qingdao, one of the absolute water shortage Chinese cities, is taken as an example to determine the storm water utilization potential based on the monthly precipitation data from 1986 to 2005. According to Qingdao medium and long-term development planning, the water shortage volume in different periods is forecasted. Comparing the storm water utilization potential with the water shortage volume in the same period, it infers that storm water utilization is effective to alleviate water crises in most Chinese cities and boost the socio-economic in a healthy and sustainable way.","PeriodicalId":6328,"journal":{"name":"2011 International Conference on Computer Distributed Control and Intelligent Environmental Monitoring","volume":"4 1","pages":"1722-1725"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87850064","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}

The soil samples were recollected according to the sampling points of Second National Soil Survey. Based on application of geographical information system (GIS) and SPSS software, the content, distribution and its influence factors of available Cu in cultivated soils were analyzed. The results showed that: the average available copper content in soil depth of 0-40cm of cultivated land in Zhuhai is 3.13mg¡¤kg-1, variation range is 0.02-99.96mg¡¤kg-1. When the soil depth of cultivated land increased, available copper content ranges rapid decreased. The rank of content range, average, standard deviation, variance, skewness and peakness of different land use types in decreasing order is vegetable soil > paddy field > dry land. Regression analysis using line equation, power function and exponential function between available copper content and affecting factors shows that: a positive correlation exits between pH and the available copper content in some soil depth. There is a remarkable positive correlation exit between the available copper content and organic matte. The available copper content and clay content also has a remarkable positive correlation. In soil depth of 12-27cm, the correlation coefficient of line equitation between pH and the available copper content is the biggest. In soil depth of 27-40cm, the correlation coefficient of exponential function between clay content and the available copper content is the biggest. In other soil depth, the correlation coefficient of power function between the available copper content and its affecting factors are the biggest. There are significant differences among nature affecting factors of available copper content in different depth of cultivated land. When pH ¡Ü 7.0 and pH £¾ 7.0, affecting factors of available copper content in soil depth of 0-12cm in decreasing order is organic matter > pH > clay content and clay content > organic matter > pH, while affecting factors of available copper content in soil depth of 12-27cm¡¢27-40 cm in decreasing order is clay content > organic matter > pH and organic matter > clay content > pH.","PeriodicalId":6328,"journal":{"name":"2011 International Conference on Computer Distributed Control and Intelligent Environmental Monitoring","volume":"9 1","pages":"1350-1353"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74200804","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}

The analysis shows, in addition to cadmium and lead, other elements fit relatively well, which reflects a good spatial structure of the heavy metals content of soil in Dexing. The relatively poor fitting effect of cadmium and lead indicates poor spatial structure and complex control factors. Various factors interaction result in the element content distribution going to complexity. Most elements show some directional features, which are consistent with the same feature in the distribution maps. The distribution maps show that high contents of heavy metal are focus on the Dexing mining area and some small mining areas. The mine exploration is the main reason for the rise of the content of heavy metals and even pollution in Dexing area.","PeriodicalId":6328,"journal":{"name":"2011 International Conference on Computer Distributed Control and Intelligent Environmental Monitoring","volume":"34 1","pages":"1785-1788"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79770085","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}
