Investigating, exploring and utilizing epikarst water is a hot issues for scholars in recent years. The epikarst spring in the Longhe rocky desertification area in SW China was selected for this study. Continuous auto-monitoring of the spring's discharge and rainfall had been done from 2003 to 2005. The results indicated that Flux of epikarst springs is small and will stop flow in a long time and has a sensitive response to rainfall, at the same time,epikarst springs Water resource in epikarst area distribute unequably in different season. The storage and derivation technique, which is a economice, effective and universal way, distribute widely in karst mountain area in SW china. At the same time, adding forest coverge in catchment area, developing water conservation forest, enhancing the regulation and storage ability of epikarst zone to water cycle, increasing water resources of epikarst springs and extending its flow time are the basic way of advancing the effective utilization of epikarst water resources.","PeriodicalId":6425,"journal":{"name":"2011 International Symposium on Water Resource and Environmental Protection","volume":"11 1","pages":"528-531"},"PeriodicalIF":0.0,"publicationDate":"2011-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90005667","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}

Moreover, the correlation between the runoff and the concentrations of COD and NH3-N at the main hydrological stations in the Wei River reach was discussed. The conclusions can be drawn from the results. (1)The middle and lower stream of the Wei River reach in Shaanxi province has already been polluted. The concentrations of COD, NH3-N BOD5 and DO exceed the national surface water quality standards from the Xingping control section to the Tongguan control section. (2) The average runoff of the Wei River amounts to 51.91×108 m3, which equals to 70 percent of the average annual runoff volume of the Wei River over the period from 1959 to 2008. The available water resource descends in terms of the runoff volume of the Wei River reach. The scarcity of water resource resulting from the water quality problems has been more and more severe in the region. (3) The concentrations of COD, NH3-N correlates to the runoff weakly in the upstream of the Wei River, while the average negative correlation between the pollutant concentrations and runoff is shown in middle and lower stream of the Wei River. Compared to COD, NH3-N correlates to the runoff the Wei River more apparently.","PeriodicalId":6425,"journal":{"name":"2011 International Symposium on Water Resource and Environmental Protection","volume":"1996 1","pages":"863-866"},"PeriodicalIF":0.0,"publicationDate":"2011-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90417854","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}

At the same time, human disturbance had improved soil structure, and increased vegetation litter, leading to the enhancement of soil respiration and increase in CO2 discharge flux. However, due to the increment rate of vegetation carbon fixation amount was much higher than the increment rate of soil CO2 discharge flux, the implementation of ecological restoration techniques enhanced carbon “sink” function of saline-alkali grassland, and with the increasing intensity of human disturbance in ecological restoration techniques, this increasing trend was even more evident.","PeriodicalId":6425,"journal":{"name":"2011 International Symposium on Water Resource and Environmental Protection","volume":"36 1","pages":"2243-2247"},"PeriodicalIF":0.0,"publicationDate":"2011-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76609562","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}
