Management Implications to Water Resources Constraint Force on Socio-Economic System in Rapid Urbanization: a Case Study of the Hexi Corridor, NW China
Water Resour Manage (2007) 21:1613–1633 DOI 10.1007/s11269-006-9117-0 Management Implications to Water Resources Constraint Force on Socio-economic System in Rapid Urbanization: A Case Study of the Hexi Corridor, NW China Chuang-lin Fang & Chao Bao & Jin-chuan Huang Received: 11 January 2006 /Accepted: 30 October 2006 / Published online: 6 December 2006 # Springer Science + Business Media B.V. 2006 Abstract As water has become the shortest resources in arid, semi-arid and rapid urbanization areas when the water resources utilization has approached or exceeded its threshold, water resources system slows down the socio-economic growth rate and destroys the projected targets to eradicate poverty and realize sustainable development. We put forward the concept of Water Resources Constraint Force (WRCF) and constructed a conceptual framework on it. Conceptual models on the interactions and feedbacks between water resources and socio-economic systems in water scarce regions or river basins indicate that, if the socio-economic system always aims at sustainable development, WRCF will vary with a normal distribution curve. Rational water resources management plays an important role on this optimistic variation law. Specifically, Water Demand Management (WDM) and Integrated Water Resources Management (IWRM) are considered as an important perspective and approach to alleviate WRCF. A case study in the Hexi Corridor of NW China indicates that, water resources management has great impact on WRCF both in Zhangye and Wuwei Region, and also the river basins where they are located. The drastic transformation of water resources management pattern and the experimental project – Building Water-saving Society in Zhangye Region alleviated the WRCF to some extent. -

Abstract The nodulation and nitrogen fixation of major cultivated and wild legumes dispersed over 36 genera, 98 species have been studied in some region of Gansu province and Ningxia Hui Autonomous Region. 360 strains of root nodules bacterial have been isolated from about 400 samples, among them of 44 strains were from 30 species that have not been reported yet in Allen`s “The Leguminoaes” and other literatures. The most of which were tested infecting in 22 model species that belong to 20 genera as host, 81.2% strains of tested rhizobia can nodule with host plants. Above 85% of those nodule samples were effective for nitrogen fixation. The result showed that the activities of nitrogen fixation in nodules of various species varied greatly and all of them were low. 46.6% of them are under 1 µmolC2H4/gFWh and more than 10 µmolC2H4/gFWh is only 6.8%.The nitrogenase activity was closely related to the growth period of plants. 2.

Interactive comment Interactive comment on “Climate-driven desertification triggered the end of the Ancient Silk Road” by Guanghui Dong et al. Guanghui Dong et al. [email protected] Received and published: 19 November 2020 Reviewer #3: The general argument of the paper is that cold and dry climate pre- vailing during the Ming dynasty in the region of Dunhuang around 1450 CE was the chief cause for the closure of the Silk Road (meaning by it the system of communi- cation between the Chinese capital and Central Asia) – Evidence for this hypothesis is presented in the form of climate proxies from the site of Xishawo (XSW), consist- ing of paleosols and sediments, dated on the basis of 14C analysis of charcoal and Printer-friendly version wood samples from the same section of the site. The laboratory analysis showed a increase in desertification, attributed to especially dry and cold climate, between 1450 Discussion paper and 1530. – The authors also consulted historical sources and compared their results with written records. The main thesis of the study is that the closure of the trade route C1 and abandonment of Dunhuang in the early 16th century was due to climatic change rather than two other causes considered here, namely, the “alternative” maritime route CPD and warfare. In their analysis the authors argue against these two possibilities, and exclude them in favor of a climate change as the single cause for the closure of the Silk Road.
