Now agricultural loading on the natural ecological system became more intensive - ecological situation worsens and efficiency of landscapes decreases. The considerable part of agricultural enterprises and subsidiary small-holdings (SSH) in the Republic Buryatia and Mongolia are located directly in the basins of the lakes Baikal and Khovsgol. The principal cause of low efficiency of pastures is connected with a big overload caused by unsystematic pasture of cattle. In the article some aspects of research of agricultural activity on agrolandscapes in coastal zones of the lakes Baikal and Khovsgol are considered.

Key words: Agroecology, agriculture, agrolandscapes, vegetation, agrarian nature management.
