Features of the floristic composition of communities with the participation of Malus sieversii on the territory of “Zhongar - Alatau” National Park

Dzungarian Alatau mountain is a unique place of agrobiodiversity concentration. The apple forests consisted the red book species Malus sieversii (Ledeb.) M. Roem. in combination with Abies sibirica Ledeb. and Populus tremula L. form pronounced altitudinal-climatic band within 1200-1600 m Alatau. In this article features floristic composition communities four gorges Zhongar-Alatau National Park (Pikhto-voye, Mushabay, Kok-Zhota Krutoye) were revealed. Plant characteristic forest belt are shown. studied communities, there 138 higher vascular plants from 110 genera, 42 families. leading families terms number Asteraceae, Apiaceae, Rosaceae, Poaceae, Lamiaceae. Generic coefficient was revealed as 79.7 %. ecological geographical analysis noted indicates that richness mainly due to natural conditions growth, which height, exposure, moisture content substrate, closeness crowns tree canopy. addition, degree anthropogenic impact on great importance.
