Over the past time anthropogenic influence has greatly increased the human-made landscapes at the expense of the natural ones. It results in losses of biological and esthetical diversity, landscape quality. Improvement of landscapes quality is getting a one of the main objective of regional planning and decision-making. The research focuses on determination of landscapes, which are suitable for biodiversity conservation on the regional level. We investigate the territory of Eastern Belarus Landscape Province (23,86 thousands km2), which is characterized by permanent human impacts and by predominance of the agricultural and agro-forestry landscapes of the secondary - moraine and loess landscapes. The assessment has been carried out within the species (vid) of natural-anthropogenic landscapes (NAL). Landscape indexes have been calculated such as patch size, patch density, shape index, diversity index, proximity and naturalness. The assessment has been carried out for landscape and ecosystem level. All values of landscape indexes were divided into three intervals: low, average and high. he intervals have been scored. Criteria for landscape indexes were developed according to importance for biodiversity conservation. The additional data about rare and threatened species has been added. As a result, the map of suitability for biodiversity conservation has been made with the following classification as (1) good, (2) satisfactory and (3) not satisfactory. The spatial analysis has been made using ArcView 3.2 GIS software.
