Jin Rui, Li Xin, Yan Baoping, Luo Wanming, Li Xiuhong, Guo Jianwen, et al. Introduction of Eco-hydrological Wireless Sensor Network in the Heihe River Basin[J]. Advances in Earth Science, 2012, 27(9): 993-1005.

This paper gives an introduction about the ecohydrological wireless sensor network in the Heihe River Basin, including its background, observation objective, node type definition, data transfer mode, and the optimal spatial sampling strategy. All kinds of meteorological, hydrological and ecological observation sites distributed in both the Babaohe River Basin in the upstream and the Daman/Yingke irrigation districts in the middle stream of the Heihe River basin are integrated and communicated to the data center through the wireless transferring technique. An automatic, intelligent, and remotecontrollable ecohydrological wireless sensor network is established. Meanwhile, relevant researches about optimal spatial sampling strategy of the wireless sensor network nodes have been carried out to capture the spatialtemporal dynamics and spatial variations of the key ecohydrological parameters in the heterogeneity land or at remote sensing pixel scale. As a result, it is anticipated to improve the integrated, standardized and automated observation capability for the hydrological and ecological processes research at the basin scale.
