The Resilience of Chinese Vineyards to Land Degradation Using a Societal and Biophysical Approach
land Review Analyzing Regional Geographic Challenges: The Resilience of Chinese Vineyards to Land Degradation Using a Societal and Biophysical Approach Yang Yu 1,2 and Jesús Rodrigo-Comino 3,4,* 1 School of Soil and Water Conservation, Beijing Forestry University, Qinghua East Road 35, Beijing 100083, China; [email protected] 2 Jixian National Forest Ecosystem Research Network Station, CNERN, Beijing Forestry University, Beijing 100083, China 3 Soil Erosion and Degradation Research Group, Department of Geography, Valencia University, 46010 Valencia, Spain 4 Department of Physical Geography, Trier University, D-54286 Trier, Germany * Correspondence: [email protected] Abstract: Land degradation, especially soil erosion, is a societal issue that affects vineyards world- wide, but there are no current investigations that inform specifically about soil erosion rates in Chinese vineyards. In this review, we analyze this problem and the need to avoid irreversible damage to soil and their use from a regional point of view. Information about soil erosion in vineyards has often failed to reach farmers, and we can affirm that to this time, soil erosion in Chinese vineyards has been more of a scientific hypothesis than an agronomic or environmental concern. Two hypotheses can be presented to justify this review: (i) there are no official and scientific investigations on vineyard soil erosion in China as the main topic, and it may be understood that stakeholders do not care about this or (ii) there is a significant lack of information and motivation among farmers, policymakers Citation: Yu, Y.; Rodrigo-Comino, J.

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. -

For this paper, we took the desert on the eastern shore of Qinghai Lake as the study area. We analyzed a variety of aged Hippophae rhamnoides communities and aeolian activities, and we discuss the relationship between them. The main conclusions are as follows: (1) With an increasing number of binding years, the species composition became more abundant, natural vegetation began to recover, and biodiversity increased year by year. At the same time, plant height, canopy width, and community coverage increased, but H. rhamnoides coverage was reduced to 36.70% as coverage of Artemisia desertorum increased to 25.67% after 10 years of fixing. -

Water Use Strategy of Four Desert Shrubs in Gonghe Basin, Qinghai-Tibetan Plateau
Chapter 5 Water Use Strategy of Four Desert Shrubs in Gonghe Basin, Qinghai-Tibetan Plateau Yajuan Zhu Additional information is available at the end of the chapter http://dx.doi.org/10.5772/63195 Abstract Gonghe basin is located in the ecotone from the semi-arid to arid zone on the northeastern Qinghai-Tibetan Plateau. Caragana intermedia and Caragana korshinskii are dominant on sand dunes. Salix psammophila and Salix cheilophila are mainly distributed on interdune. Water source of four desert shrubs was examined by δD and δ18O, and their long-term water use efficiency (WUE) was compared by leaf δ13C. Four desert shrubs used different depths of soil water depending on their availabili‐ ty in different seasons, including shallow soil water recharged by rain in spring or summer and deep soil water recharged by ground water. The reliability on ground water of two Salix shrubs on interdune was more significant than two Caragana shrubs on sand dunes. Moreover, the WUE of four shrubs decreased in drought spring. Two shrubs in Caragana had similar WUE in the growing season. However, the WUE of S. psammophila was always higher than that of S. cheilophila, which might have more adaptability in Gonghe Basin. Keywords: water source, water use efficiency (WUE), stable isotope, soil water, ground water 1. Introduction In desert ecosystems, water is a restrictive factor for plant survival and growth because of low and unpredictable precipitation and high evaporation [1, 2].

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. Introduction The area of Gansu province and Ningxia autonomous region in the northwest China is approximately 450,000 Km2, there are small Mt. Longshan and west Qinling with semi-humid, semi-arid and deciduous broad-leaved forest warm temperate zone and wood-grass climate, Bailong River drainage area with semi-tropical continent humid climate, and Allah friendly plateau with middle Asia continent arid hungriness climate. -
