常规的信息收集渠道难以获取国际河流研究所需的有效信息,探索新的信息收集方式对资料稀缺区开展水文水资源研究十分必要且关键。在Internet海量信息中,Google Earth(GE)平台的出现,为资源环境、交通规划等诸多领域提供了"身临其境"的远距离信息检索模式。通过基于GE平台的资料稀缺区水资源开发利用状况评价的应用框架和评价方法,并以巴尔喀什湖流域中下游为例开展了应用研究。结果表明:GE平台可成为资料稀缺区水资源开发利用研究的有效信息收集手段,文中所提出的框架、应用流程和评价方法具有较好的可操作性;研究区在1990年初就形成了以伊犁河中下游为主体、准噶尔区与巴尔喀什湖北部诸小河为重要用水区的基本格局;随着研究区经济社会发展的剧烈波动,其用水量经历了"增长-顶峰-剧减-恢复性增长"的演变格局,目前其用水量预计已恢复至20世纪80年代中期的水平,即65×108m3左右。
It is difficult for the general information gathering channels to get effective information required for research on international rivers,it is necessary and critical to explore new method of information collection in order to investigate hydrological water resources in some places where the data lack.In the million information of Internet,emergence of the platform-Google Earth(GE) provides a "scene" mode of remote information retrieval for environmental resources,traffic planning and many other fields.This article probed into the application framework and assessment method used for water resources development and utilization in the area with lack of needful data based on the GE platform,such research was applied to the middle-lower reaches of Balkhash Lake basin,the results show that the GE platform can be used as effective information gathering means for water resources development and utilization in area with lack of needful data.The proposed framework,application flow chart and assessment method have preferable maneuverability in this disquisition;the basic pattern of investigation area that was formed in early 1990,namely the middle-lower reaches of Ili River were regarded as main body,Junggar region and northern small rivers of Balkhash Lake were considered as important water system area;with the dramatic fluctuation in economic and social development of the investigation area,his water consumption has undergone the evolvement pattern of "growth-peak-acute reduction-restorative growth".Now it is expected to have resumed its water consumption to the level in the mid 1980's,which is around 6.5 billion m3.
