At present, Republic of Moldova is in a difficult process of strengthening ecological network and establishing the necessary functional relations between its main components. Most natural ecosystems, especially forests and natural meadows have been converted to agricultural land which possess a low ecological stability and are massively affected by erosion and landslides. Starting from these premises, this paper aims to research the spatial dynamics of ecological stabilizing land in relation to agricultural, industrial and residential land, with a smaller ecological stability and a greater impact on the natural ecosystems and biodiversity. The main analyzed subjects relates to dynamics and status of forests, pastures, perennial plantations, arable lands and of natural areas protected by state. There are elucidated the causes of reducing of ecological stabilizing land, during the past two centuries, socio-economic and environmental conditions in which respective processes have been manifested. It also proposed some recommendations for expanding and optimizing the various categories of ecologically stabilizing land.
