【 摘 要 】

Spruce (Picea abies (L) Karst) is referred to as late-succession species of the Moscow region. However, its large areas have been and continue to be maintained by cultures initially planted to timber harvesting but remained unlogged as all the forests of the Moscow region were referred to as protective ones. During the last years, approximately 20% of spruce forests dead, mainly monodominant cultures with reduced tolerance to pests and extreme weather factors. The forests with the predomination of spruce in the canopy and subcanopy were studied on permanent observation plots in the northeastern part of the Moscow region. Twenty of 25 spruce stands have the diameter structure homogenized by previous treatments. The traditional practice of forming high-density close-canopy stands led to the suppression of spruce second layer and understory and its substitution by linden (Tilia cordata L) and maple (Acer platanoides L). Both natural species composition shift and ecological and recreational functions of forests in the Moscow region demand to reject the outdated practice of creation and artificial sustention of monodominant spruce forests. A complex management strategy should be elaborated for the protective forests of the Moscow Region, turning from passive following of forest decline to active formation of complex polydominant stands.
