1. Introduction
According to the Intergovernmental Panel on Climate Change (IPCC, 2007), global air temperature is predicted to increase by 1.4–5.8 C by the end of the 21 st century as a result of increasing emissions of carbon dioxide and other greenhouse gases (GHG). Temperature influences nutrient cycling and organic matter in terrestrial ecosystems, mainly through plant-mediated responses, such as increased and qualitatively altered rhizodepositions (Zhang et al., 2015). Root exudates sustain a larger and more active microbial community in the rhizosphere than occurs in bulk soil; microorganisms utilize these lowmolecular-weight organic compounds as an energy source for proliferation and enzyme synthesis (Renella et al., 2006; Baudoin et al., 2003; Berg and Smalla, 2009). It has been shown that increased air temperature has variable effects on the composition and activity of the rhizosphere microbial community composition and enzyme activity, depending on plant type (herbaceous, woody) and species, soil type, and other ecosystem characteristics (Uselman et al., 2000; Maksymiec, 2007; Frey et al., 2008; Hayden et al., 2012; Jia et al., 2015; Schindlbacher et al., 2011; Wang et al., 2013; A’Bear et al., 2014). The rhizosphere is a critical environmental compartment in which fundamental processes responsible for ecosystem functioning and crop production occur (Coleman et al., 1992), and any change in soil quality, including metal pollution, can impact the cycling of carbon and other nutrients. Soil pollution by heavy metals is widespread, and its impacts on soil microbial diversity and soil ecological functions have been widely reported (D’Aascoli et al., 2006; Gomes et al., 2010). Heavy metal pollution is often associated with the same anthropogenic activities (e.g. heavy industry, intensive agriculture) that cause greenhouse gas emissions and corresponding increases in air temperature, particularly in the emerging economies. Among heavy metals, cadmium (Cd) and lead (Pb) are highly toxic and are often both present in contaminated soils (Meng, 2000; Mleiki et al., 2015). In China, more than 2.0 109 ha of land is contaminated with heavy metals (Guo et al., 2011). The effect of metals, including Cd and Pb, on microbial biomass and enzyme activity in the rhizosphere have mostly been examined using model studies without plants (Liao et al., 2006; Renella et al., 2006; Xu et al., 2006). These studies have shown reduced microbial mineralization capacity of organic compounds in root exudates (Renella et al., 2006), but this negative impact may be balanced by the increased concentration of organic compounds in the rhizosphere of plants exposed to Cd pollution and increased air temperature (Jia et al., 2015). Currently, information about the interactive effects of soil heavy metal pollution and elevated air temperature in the rhizosphere of real plant/soil systems is still scarce.
