A few methodological issues were discussed in this paper, which involved in the ecological risk assessment in agricultural soil, including (1) Reference system: it was proposed to use forest soils in the mountainous areas as the reference systems. (2) The Distribution of research stations/sites: the research stations should be arranged according to the hierarchies of ecological factors. (3) Layout of quadrats in monitoring areas and sampling. (4) The indicators for ecological risk assessment: these indicators are designed on the basis of the biological mechanisms underlying the mineralization of soil organic matter. In reference system, the first, secondary, and tertiary hierarchies are climate zone, location, and site, respectively, the basic value of indicators in these different levels will be used for ecological risk assessment of agricultural soil.
Keywords:environmental pollution, ecological risk, assessment indicators, soil organic matter, available phosphorus, F/B???
