Корреляционные отношения между микроклиматическими показателями в различных фитоценозах юга Сахалина

Корреляционные отношения между микроклиматическими показателями в различных фитоценозах юга Сахалина

Abstract

Measurements of microclimatic characteristics of different phytocoenoses were carried out at the permanent stations in the south of Sakhalin region. The temperature and humidity of air, the temperature and moisture of the upper layer of soil, light, height of snow cover and the temperature of it’s upper layer were measured and the samples of water were taken to test its turbidity. The correlation matrices were constructed taking into account all the indicators. The correlation coefficients reflected the positive, negative and indirect link between microclimatic parameters in the phytocenosis of the water protection zones of the Ai river and the mountain stream of the Susunai Ridge. It was concluded that not only plant communities influence the correlation of climate indicators, but also anthropogenic changes in them. At the stations lacking the woody vegetation, the connection between the climatic and hydrologic indicators was more evident and had a moderate and strong degree in the comparison with the stations located in the dark coniferous forest. So, using the method of the correlative links we obtained the probative basis for the anscertainment of the reasons which causes the microclimate changes and the changes of hydrologic indicators at ecosystem consisting of the watercourses and their catchment area.

На постоянных станциях на юге Сахалина проводили измерения микроклиматических показателей в различных фитоценозах. Измеряли температуру приземного и припочвенного слоёв воздуха, а также верхних слоёв почвы и снежного покрова, влажность приземного воздуха и верхнего слоя почвы, освещенность, высоту снежного покрова. Кроме того, в прилегающем водотоке брали пробы воды на мутность и измеряли её температуру. Между всеми показателями построили корреляционные матрицы. Коэффициенты корреляции отражали положительную, отрицательную и косвенную связь между микроклиматическими показателями в фитоценозах водоохранных зон р. Ай и горного ручья Сусунайского хребта. Пришли к заключению, что на взаимосвязь показателей микроклимата, помимо самих растительных сообществ, также влияют и антропогенные изменения в них. На станциях, лишенных древесной растительности, связи между климатическими и гидрологическими показателями были более заметны и носили умеренную и сильную степень, чем на станциях, расположенных в темнохвойном лесу. Итак, используя метод коррелятивных связей, получили доказательную базу для установления причин, обусловливающих изменения микроклимата и гидрологических показателей в мезоэкосистемах, состоящих из водотоков и их водосборной площади.
