“…This illustrated that the soil can store water for dry periods even under the variable rainfall, which were supported by previous studies (Wang, Cresswell, Xu, & Jiang, 2009; Wong & Asseng, 2006). Moreover, our results upheld Zhang and Li (2014)’s finding in the Jing‐Jin‐Ji Plain, where the need of large amounts of irrigation for winter wheat in our simulation study, coincided with the majority of cones of ground water depression in the NCP in their study.…”

Improving winter wheat (Triticum aestivum L.) productivity and water use efficiency (WUE) in the North China Plain (NCP) is critical to maintain grain security and ease the water shortage in this region. This study was conducted to examine the optimal irrigation amount (OI) for winter wheat across the NCP and analyze its responses to the climate, soil, and cultivar. We applied a novel approach with the Agricultural Production Systems sIMulator (APSIM) during 1961-2010 to estimate the OI by considering the trade-off between yield and WUE. Our results suggested that the optimum irrigation amount determined by climate (OI c ) ranged from 3-342 mm for simulation experiments considering climate impacts alone. When soil conditions were additionally considered, the optimal irrigation amount (OI cs ) showed an average decrease of 45 mm across 19 sites in the northern NCP but an average increase of 42 mm across 29 sites in the southern NCP. When all three factors were included, the estimated optimal irrigation amount (OI csc ) fell within the range of 3-286 mm across the NCP, lower than OI c and OI cs . Climate, soil, and cultivar explained 54, 27, and 19% of the spatial variation in the optimal irrigation amount, respectively. Further analysis indicated relatively higher optimal irrigation amounts for late-maturing cultivars, but their inter-annual variations and decadal changing rates were lower relative to the early-and medium-maturing cultivars. Our study demonstrated the incorporation of the genotypes and environmental factors, and recommended the optimal irrigation amount of 3-286 mm for winter wheat in the NCP.Abbreviations: APSIM, Agricultural Production Systems sIMulator; ET, evapotranspiration; NCP, North China Plain; OI, optimal irrigation amount; OI c , optimal irrigation amount determined by climate; OI cs , optimal irrigation amount considering climate and soil conditions; OI csc , optimal irrigation amount influenced by climate, soil, and cultivar; OI cse , estimated optimal irrigation amount of early-maturing variety Zhengmai 9023; OI csl , estimated optimal irrigation amount of late-maturing variety Lumai 21; OI csm , estimated optimal irrigation amount of medium-maturing variety Gaoyou 503; PAWC, plant available water content; PCA, principal component analysis; WUE, water use efficiency.

“…Moreover, groundwater extraction-related factors can aggravate the manifestation of modern ground fissures. The over-exploitation of groundwater in North China has led to the formation of large-scale groundwater funnels (Zhang and Li 2014). The compression of groundwaterholding strata undoubtedly accelerated this bending cracking and intensified the disaster risks of the ground fissure.…”

The Anping fissure is one typical and particular ground fissure in the North China Plain. This study was carried out in Anping area with geological means, such as surveying, mapping, trenching and drilling. The geological structure and disasters were analyzed by both qualitative and quantitative methods. The main conclusions are as follows: (1) Anping ground fissure is the local manifestation of regional tectonic stress field and is basically folding directional, hidden and intermittent. (2) Under the control of Shen-rao fault, Anping ground fissure was exposed and expanded by water-related human activities, and then was cracked by small-and medium-sized earthquakes. (3) The forming process followed the bending-cracking rules. The uplifting force from deep in the earth bent the entire overlying strata. The tangential stress below the ground surface counterbalanced the horizontal stress of soils, even breaking through their tensile strength and inducing cracks. The fissure was periodic and wavery, because the cracking force was proportional to the uplifting force but inversely proportional to the stratigraphic depth.

“…The first phase of the project will be completed after the flood season in 2014, supplying the NCP with 5.7 billion m 3 /a of water [57]. This approach should remediate the groundwater cone to some extent; however, considerable time will be required to recover the groundwater environment [58].…”

Abstract:The North China Plain (NCP) is facing a water crisis under the dual impact of natural and anthropogenic factors. Groundwater levels have declined continuously since 1960, causing a series of environmental problems that have restricted sustainable development in the region. In the present study, we first utilized a previously developed 3D groundwater model to determine changes in groundwater level in the region over the past 50 years . We then applied grey relational analysis (GRA) to identify and ordinate major factors that have contributed to these changes. The results show an overall decreasing trend in groundwater levels in this region over the past 50 years and an increase in the water table depth at a rate of approximately 0.36 m/a. Groundwater exploitation showed the most significant correlation with the groundwater table decline, when compared with other factors including precipitation and river leakage. Therefore, human activities should be considered the primary force driving the groundwater level down. The results of this study have implications for developing criteria that consider changes in both climate and socio-economics. Furthermore, since the NCP is one of the most water-scarce OPEN ACCESSWater 2014, 6 1582 and densely populated regions in the world, the analytical approach used in and the insights gained from this study are of international interest.
