This study uses a so-called R/S Analysis method to predict three major factors that affect the groundwater resources change in Minqin Oasis i.e. population, grain yield and the quantity of the upstream inflow. The results show that the Hurt index of the time series about the population in the Oasis is 0.733, which indicates that the future general changing trend of population in the Oasis is an increasing trend as the same as that in the period from 1960 to 2010. The Hurt index of the time series about grain yield in this Oasis is 0.901, which states that its future changing trend has a stronger long-term positive correlation with the increasing trend in the period from 1960 to 2010. In other words, its' future general changing trend is also increasing. The Hurt index of the quantity of upstream inflow in the Oasis is 0.916, which shows that its future general changing trend has a very strong long-term positive correlation with the decreasing trend in the period from 1960 to 2010, presenting a decreasing trend.","PeriodicalId":6394,"journal":{"name":"2012 International Symposium on Geomatics for Integrated Water Resource Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82243017","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 variation processes of the land use structure in the Upper Reaches of the Heihe River have an important effect on water resources and ecosystem of the whole watershed. The methods of remote sensing image analysis, transfer matrix and principal component analysis were employed in this paper to analyze quantitatively the course of spatial and temporal variations of three main types that woodland, grassland and cultivated land in mountain area of the Upper Reaches of the Heihe River Basin. The artificial motivation of land use changes in the study area had been indicated. The results showed: (1) the variation stages of land use demonstrated clearly in the study area, in which three kinds of land use types as cultivated land, grassland and forest land had transformed obviously in two stages of 1987-1999 and 1999-2010, that is, the area of forest decreased continuously, the area of grassland decreased at the first stage and then increased at the second stage, the cultivated land increased sharply; (2) spatial variation of single land of three types was remarkable, the distribution of forest land presented acreage in the eastern part more large than western and southern less than northern part; the area of grassland were the largest, and distribution patterns of it display more in eastern and more in south; the area of cultivated land were the least, they mainly distributed along the valleys of the Heihe River, and (3) the forest and grassland degraded seriously. The main causes of land degradation in the area under study led by population increase with excessive use of land.","PeriodicalId":6394,"journal":{"name":"2012 International Symposium on Geomatics for Integrated Water Resource Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86102150","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 ability to address jointly the environmental, economic, and social aspects of water policy is central to Integrated Water Resources Management (IWRM). SEEAW has a unique contribution to make to IWRM because it is the only approach that integrates economic accounts with accounts for water use and supply in a framework that supports quantitative analysis. Based on SEEAW framework, this paper tries to start the implementation of SEEAW at regional level in China. According to the standardized information system which harmonizes information from different sources, various relevant departments, a physical water supply and use table (SUT) in Zhangye City, an arid area in Northwest China, is compiled. The results show that the characteristics of water use in Zhangye: the high proportion of farming water use, water distribution and flows within the economic system results in the few of water quantity. It seems that, in order to improve integrated water resources management in Zhangye City, it is necessary to promote the industrialization and urbanization level. For the future of water accounting practice in China, the author concludes that although there are considerable differences on water environment statistics between China and international standards currently, under the framework of international standards, effectively achieving data integration is the future direction. The SUT compilation in China has more feasibility in practice compared with other accounts in SEEAW.","PeriodicalId":6394,"journal":{"name":"2012 International Symposium on Geomatics for Integrated Water Resource Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80428123","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}

Water resources are the primary limiting factor for the sustainable development of economy and society in the Basin. The water requirement of vegetation is the link of the relationship between the status of natural vegetation and the groundwater level in the study area. With the decrease of water resource, the scientific estimation on ecological water requirement becomes the attention-getting focus and important premise of ecosystem protected. So, The ecological water requirement of vegetation was estimated in the study based on the remote sensing and evapotranspiration process. First, this study simulated the surface flux and the evapotranspiration using the technology of remote sensing and GIS, combining the basic data such as meteorological data, Landsat TM images, current land use maps and the data from field investigate. And then the quantity of ecological water requirement was estimated based on the simulated evapotranspiration and the distributional area of vegetation. By estimation, the quantity of water requirement of dominant species, such as Populus euphratica, Tamarix ramosissima and grassland is 11.37×107m3, 0.45×107m3 and 3.24×107m3, respectively. The total ecological water requirement of vegetation is 1.506×108m3. This method afforded the effectual method for the study of regional ecological water requirement. And this study provide scientific support to banlance the water requirement from human being and natural ecosystem, and confirming the target, measure and project of ecosystem protected.","PeriodicalId":6394,"journal":{"name":"2012 International Symposium on Geomatics for Integrated Water Resource Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74348170","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}
