摘要:Environment islands in the agricultural and forest landscape of Pomerania,are most often a small patches of forest,located within the fields and a patches of the field located within the larger forest complexes. Small environmental islands play an important bio- and physiocenotic role,hence the level of their isolation is an important element of the spatial landscape structure assessment. The paper presents a method for evaluating the spatial isolation of environmental islands considering both the landscaped context of object,as well as its size. The first step to determine the isolation degree of the island was calculation of areas with a dominant landscape background (presented in the previous article). The method of isolation islands assessment allows to choose a suitable search radius,consistent with the objective of research,as well as the control the size of the island isolation,depending on the assumed search radius. Used in the work degree of isolation (I) also allows to select the optimal facilities for research on the isolation effects and the size of the islands in the species composition.
