| 中文摘要 | 西北内陆干旱区的水资源不仅是当地经济发展的重要制约因素，而且是脆弱生态系统赖以存在的基础。基于全球气候变化对降水过程、蒸散发、土壤含水量、径流量、冰川积雪和洪水干旱等极端水文气候事件等方面造成直接影响，开展干旱、半干旱地区内陆河流域水资源的变化与成因分析，对合理开发、利用干旱地区的内陆河流域水资源具有重要意义。内陆干旱区河川径流量、湖泊水量与矿化度、流域降水量、蒸发量等水文气象要素以及地面植被对气候变化具有敏感的响应，是认识流域水文过程响应于气候变化尺度和强度的重要参照系。本论文根据多年实测数据，通过趋势显著性检验、相关性分析、多元线性回归等方法对开都河流域水文气象要素(如流域降水量、径流量、气温、湖泊水位、矿化度等)变化规律进行分析探讨，探讨了流域气候变化与径流变化的关系；并通过遥感图像处理建立巴音布鲁克草原1982-2000年的NDVI时间序列与植被覆盖的空间格局变化图，分析了开都河流域源流区巴音布鲁克草原植被覆盖的年际变化，从植被的角度反映了开都河流域源区气候增暖增湿的趋势变化。\n通过以上研究，旨在通过分析开都河流域的气候变化及其水资源响应，揭示受全球气候变化影响的开都河流域水文水资源系统在运动过程中的变化机制，预测未来气候变化对水资源带来的影响，为流域水资源管理者进行合理配置和科学管理提供决策参考。 |
| 英文摘要 | Water resource is not only an determinant to the development of local economy, but also the exist foundation of the fragile eco-system in Northwest China.Based on the present condition of water circle that influenced by Global Climate Change through the influence on precipitation, streamflow, glacial, snow and extreme events about hydrology and meteorology, carry on the analysis of variation and it’s reasons of water resource of inland River Basin is important to exploit and utilize the water resourse in inland River Basin rationally.Hydrological and metrological factor such as streaflow,Lake water and it’s degree of mineralization ,precipitation,evaporation and etc.are sensitive to Climate Change in inland River Basin,those are important reference index to understand the water process that response to climate change intensity and scale.Based on years hydrology and meteorology data,this paper probe into the variation law of various hydrological and meteorological factor by Relative Analysis, Multi-variables Analysis and so on. meanwhile,the time serial of NDVI and the spatial distribution changes of 3-year mean NDVI in the early 1980s, the early 1990s, and the late 1990s in Bayinbuluke grassland are builted from 1982-2000 by remote sensing technology,and reflected the trend of climate change from the viewpoint of vegetation coverage. \nThe above mentioned research is for the purpose of analysis the climate change and response of water resource in Kaidu River Basin and Promulgates the change mechanism of hydrology &water resource system of Kaidu River Basin under the global climate change, forecast the ifluence of climate change on water resource in Kaidu River Basin in the following future,provide policy-making reference for the water resource manager to reasonable disposition and Scientific management on water resource. |
