В статье рассматриваются особенности формирования ландшафтного разнообразия вулканически активных островов. Представлен подробный анализ показателей сложности ландшафтного рисунка. Выявлены особенности изменения ландшафтного разнообразия и количественных характеристик ландшафтной структуры островов в результате вулканической активности и в периоды вулканического спокойствия. Показано, что в ряде случаев вулканический фактор является доминирующим в процессе формирования ландшафтного разнообразия острова.
The area is an important factor of formation of a landscape diversity on Islands. On the basis of the quantitative analysis of landscape structure of the Kurile and Hawaiian Islands, the steady interrelation between values of Margalef index refl ecting a landscape diversity and the island area is shown. It is also shown that coeffi cients of complexity and landscape dissociation have direct correlation with the island area. Ambiguous data are obtained during calculation of an entropy measure of landscape complexity.
On the basis of the analysis of islands-volcanoes the landscape structure of the Kuril Arc and the role of volcanic activity in formation of a landscape diversity of the territory are shown. Eruptions of volcanoes lead to increase in landscape diversity on the island. Landscape diversity grows after eruption until forming the balanced landscape structure. During the subsequent period of volcanic tranquility a phase of a landscapes relaxation comes with reduction of a landscape diversity
