中文摘要：
样带研究是研究全球变化与陆地生态系统关系最有效的途径之一。通过在黑河流域上、中、下游分别确定具有代表性的流域样带和空间网格，系统调查植被、土壤、水文、地貌和气候特征及人类活动和社会经济特征，建立相应的数据库。完善流域整体概念的野外观测试验研究网络，形成以流域为单元、科学问题为导向的生态一水文过程的数据一模拟研究平台，使我国流域生态水文研究进入国际先进行列。
英文摘要：
The terrestrial transect approach was one of most valuable tools to study the response of vegetation dynamics of terrestrial ecosystems to global changes in climate, land use and atmospheric composition. By identif- ying the typical transect and spatial grid in the upper, middle and low reaches in the Heihe River Basin, the re- searchers of project will systematically investigate the characteristics of vegetation, soil, hydrology, geomorphology, meteorology, human activity and socio-economy. In addition, the corresponding database will be created. The ob- jective of this study is to consummate the field-observation networks and form a research platform subjected to the basic eco-hydrological processes at the basin scale. It is expected that the implementation of this project will make the eeohydrological study at basin scale of our country to stride up to advanced levels in the world.
