Многолетняя динамика площади зарастания прибрежно-водной растительностью оз. Воже

Многолетняя динамика площади зарастания прибрежно-водной растительностью оз. Воже

Abstract

The aim of the research was to reveal the long-term trends in overgrowing the Lake Vozhe with coastal aquatic vegetation using the methods of spatial analysis based on satellite imageries. The results are to be used as a preliminary map for the verification of plant groups in the field conditions. The analysis of the images obtained from 1976 to 2014 showed that the area of the lake basin overgrown with helophytes had not changed. Coastal aquatic vegetation annually develops in the same areas. The composition of the dominant species of the main plant groups was the same for several years. The trend to increasing the area of overgrowing with helophytes was not found. The area of the lake that is overgrown with helophytes is 10.7%. The received classification of distribution of the vegetation in the Lake Vozhe are the basis for hydrobiological researches and the analysis of the fishery value of the water reservoir.

Целью данного исследования было методами пространственного анализа на основе космических снимков выявить многолетние тенденции в процессе зарастания прибрежно-водной растительностью акватории оз. Воже. Результат работы использовать как тематическую карту основных растительных группировок для верификации в полевых условиях. Анализ снимков за период с 1976 по 2014 гг. показал, что зарастание акватории оз. Воже гелофитами не изменилось. Прибрежно-водная растительность ежегодно развивается на одних и тех же участках. Состав доминирующих видов основных фитоценозов с годами не меняется. Тенденции к увеличению площади зарастания гелофитами не обнаружено. Площадь акватории озера, зарастающая гелофитами, составляет 10.7 %. Результаты классификации распределения растительности оз. Воже являются основой для проведения гидробиологических исследований и анализа рыбохозяйственной ценности водоема.
