Yarkand River Basin Of Xinjiang Plain Area, Sanshui And Transformation Of Research

Inversion pattern research of atmospheric water-surface water-groundwater is always an arousing popular interest task in water resources research, but for technique and measures, research fruits are not ideal. In dry areas, groundwater completely originate inversion, water cycle and evolution pattern research of groundwater is becoming inversion research of three water ,only when we master inversion pattern of water resources, we can evaluate water resources exactly; ignorance of inversion relationship and unilaterally evaluating water resources must lead to wrong evaluation result.In this dissertation we research the inversion pattern of three water through environment isotope information analysis , evaporation pattern analysis and inversion analysis of groundwater; quantitatively analyse inversion amount through rule computational method and numeric value imitation, supplying scientific foundation for evaluation of water resources and rightful development and use.Main achievements as follows:(1) Information of isotope make you know that groundwater is not directly infiltrating of rainfall, but seepage provision of surface water. There are two water cycle systems that are mutual independence and interaction, receiving provision from yeerqiang river and tizinapu river.(2) Evaporation capacity is related with evaporation capability ..soil texture,embedded depth of groundwater. Evaporation varies from evaporation capability , embedded depth of groundwater is more easy, the effect is more obvious; Evaporation capacity decreases if embedded depth of groundwater become deeply, and close to zero under the some depth; Evaporation capacity of different soil texture is different .at ordinary situation , if embedded depth of groundwater is easy, Evaporation capacity of the wide and grit soil is powerful; if embedded depth of groundwater is deep, Evaporation capacity of the slender and viscosity soil is powerful.(3) Dynamic state of groundwater in riverside displays:At middle and supreme areas of yeerqiang , no matter abundant water season or low water season, river water always recharge groundwater. At downsteam, in abundant water season , river water recharge groundwater; in low water season groundwater recharge the river. Cut plane datum only illustrate recharge and drainage relationship of part areas of the river, even though we conclude qualitative conclusion through cut plane datum, but we must make further research from qualitative conclusion to quantum .(4) Evaluate inversion quantity of water resources through general computational method and numeric value imitation, -and adopt numeric value imitation(Visual MODFLOW) to establish containing water system model, simulate the input and output changes of present year and planning year, and then valuate inversion quantity of water resources.
