“…Li et al (2009) found that crop rotations increased SOC and TN densities by 30-65% and 61-64%, respectively, in the 0-30 cm soil during the 10 years of cultivation after the desert was transformed into irrigated cropland. The SOC and TN contents in the topsoil of sand-fixing shrubs, irrigated cropland and shelter forest increased with time after the reclamation of desert land (Su et al, 2007(Su et al, , 2010a(Su et al, , 2010b. Su et al (2009) reported that SOC and TN accumulated at rates of 0.4 Mg C ha −1 year −1…”

“…Soil C and TN are controlled by various natural factors such as climate change (He et al, 2014;Rustad and Fernandez, 1998), topographical factors (Fernández-Romero et al, 2014;Griffiths et al, 2009;Kunkel et al, 2011;Parras-Alcántara et al, 2015b), vegetation conditions (Fu et al, 2010;Kunkel et al, 2011) and soil properties (Côté et al, 2000;Su et al, 2007). Anthropogenic activities have been shown to have profound impacts on soil C and TN status in recent decades .…”

“…Currently, research related to oasis change has focused on four aspects: analyzing the land use patterns in oasis agricultural region Guo et al, 2008;Hu and Li, 2014;Wang et al, 2014), discerning the relationship between agricultural oasis change and water resources (Misak et al, 1997;Siebert et al, 2007), assessing the ecological effects of agricultural oasis changes (Su et al, 2007;Zhang et al, 2014), and discussing the suitable scale of an agricultural oasis (Ling et al, 2013). Although great efforts have been made in the field of oasis change, less attention has been paid to identify the factors driving oasis change.…”

“…After the foundation of the People's Republic of China in 1949, as well as the implementation of reform and the opening-up policy in 1978, the economy in China developed rapidly, inducing the evolution in agricultural oases. The evolution of agricultural oases has two opposite processes: oasification and desertification (Li et al, 2006;Su et al, 2007;Zhang et al, 2003). Agricultural oasification usually means the expansion of an agricultural oasis, i.e.…”

a b s t r a c tThe Heihe River Basin (HRB) is the second largest inland river basin in the arid region of northwestern China. An agricultural oasis is a typical landscape in arid regions providing precious fertile soil, living space and ecological services. The agricultural oasis change has been one of the key issues in sustainable development in recent decades. In this paper, we examined the changes in the agricultural oasis in HRB and analyzed the socio-economic and climatic driving forces behind them. It was found that the agricultural oasis in HRB expanded by 25.11% and 14.82% during the periods of 1986-2000 and 2000-2011, respectively. Most of the newly added agricultural oases in HRB were converted from grassland (40.94%) and unused land (40.22%). The expansion in the agricultural oasis mainly occurred in the middle reaches of HRB, particularly in the counties of Shandan, Minle, Jinta and Jiuquan city. Changes in the rural labor force, annual temperature and precipitation have significant positive effects on agricultural oasis changes, while the ratio of irrigated agricultural oases has significant negative effects on agricultural oasis changes. The agricultural oasis expansion in HRB is the combined effect of human activity and climate change.

“…Previously, a wide range of mathematical techniques were proposed for planning regional ecosystems with a sustainable development manner (Higgins et al, 1997;Su et al, 2007;Erol and Randhir, 2013;Gumiero et al, 2013;Natuhara, 2013;Recknagel, 2013;Yang and Chen, 2013;Yu et al, 2013;Ling et al, 2014;Mao et al, 2014). Curtis (2004) proposed a multiple criteria analysis method to estimate forest ecological service value in multiple forest management policies and analyze the multiple strategies of ecological compensation.…”

A B S T R A C TA relative interval-regret analysis (RIRA) method is developed for regional ecosystem management under uncertainty through incorporating interval-parameter programming (IPP) and minimax relative regret (MRR) analysis techniques within a general framework. RIRA can handle uncertainties expressed as intervals and random variables without knowing probability distributions and only needs a list of possible scenarios that may occur; it can also incorporate ecosystem services valuation approaches directly into the optimization process, such that an effective linkage between eco-compensation costs and ecosystem service losses can be provided. The RIRA method is applied to a real case of planning regional ecosystem of Dongying, where the natural ecosystem has suffered the severe degradation due to large-scale land reclamation projects. Results of land-use pattern, ecological compensation strategy, and industrial pollution-mitigation scheme can be obtained. The results reveal that, although large-scale reclamation projects can bring benefits and make a significant contribution to local economic development, they can also result in many negative effects to the coastal ecosystem, such as endangering animals and plants, changing intrinsic gas regulation, as well as altering natural nutrient cycling. Moreover, the results indicate that eco-compensation cost is much higher than the cost for reclaimed land use, disclosing that eco-compensation mechanism is desired for curbing excessive reclamation activities. These findings can facilitate the local decision makers in not only considering regional ecosystem integrity but also gaining insights into the tradeoff between socio-economic development and eco-environmental sustainability.
