黑河流域是我国第二大内陆河流域，从流域上游到下游，以水为纽带形成了“冰雪/冻土－森林－草原－河流－湖泊－绿洲－沙漠－戈壁”的多元自然景观，流域内寒区和干旱区并存，山区冰冻圈和极端干旱的河流尾闾地区形成了鲜明对比。与此同时，黑河开发历史悠久，人类活动显著地影响了流域的水文环境，2000多年来，这一地区的农业开发，屯田垦殖，多种文化的碰撞交流、此消彼长，无不与水深刻地联系在一起。自然和人文过程交汇在一起，使黑河流域成为开展流域综合研究的一个十分理想的试验流域。无论从黑河流域独特的自然地理环境，还是从几千年的人类活动影响，黑河流域都是我国内陆河研究的重要基地（Cheng et al., 2014）。目前，大量科学研究与实验积累下来的丰富和宝贵的资料，为流域生态水文研究奠定了很好的科学数据基础。...
