Elaboration of a system for assessment of agricultural land bio-diversity in Siberia

摘要

System crisis in Russian agriculture has negatively affected the state of bio-diversity. In Siberia this is caused by the following: increased forest cutting and poaching, soil erosion, silting of water basins, loss of soil fertility, and degradationof pasture fields. The way out of this situation is seen in conducting agricultural activities on the basis of ecological principles. In addition to the improvement of the ecological situation in Russia this will make it possible to get maximum economiceffect with low investments, which is extremely important in the present environmental crisis. In the last six years we have tried to develop a system for assessing agricultural land biodiversity. Some groups of the most common soil and epigeous invertebrates have been selected for collecting the data concerning changes of agro-landscape bio-diversity caused by human activity.
