Abstract

Early flowering plants (ephemers and ephemeroids) are an important component of the biosystem of steppes and deserts. These species form perennial pasture communities, for early grazing. The present work was conducted to evaluate the floristic checklist and ecological uniqueness of early flowering plants of Central Kazakhstan, in the forest-steppe regions of Em-Bulak region and Edige mountains, during 2021 and 2022. A total of 26 species of ephemers and ephemeroids were recorded, which belong to 16 families: Liliaceae – 3 species, Asteraceae – 3 species, Ranunculaceae – 3 species, Rosaceae – 3 species, Brassicaceae – 2 species, Boraginaceae – 2 species, the other families are represented by one species. According to ecomorphological characteristics: 8 species (31%) belong to the xerophyte group, 6 (23%) to the xeromesophyte group, 7 (27%) to the mesoxerophyte group and 5 (19%) to the mesophyte group. Also, as a result of our research we found two species of plants which are included in the Red Book of the Republic of Kazakhstan – Pulsatilla patens (L.) Mill. and Tulipa patens Agardh. ex Schult. f. The data obtained can be used for environmental monitoring and issues of rational nature management of wild plants of Central Kazakhstan.

乌里陶山脉（哈萨克斯坦中部）早花植物的多样性

早花植物（ephemers 和 ephemeroids）是大草原和沙漠生物系统的重要组成部分。这些物种形成了多年生牧草群落，用于早期放牧。本研究于 2021 年和 2022 年期间在艾姆-布拉克地区和埃迪杰山脉的森林草原地区对哈萨克斯坦中部早花植物的花卉清单和生态独特性进行了评估。共记录了 26 种表花植物和昙花植物，它们隶属于 16 个科：百合科--3 种，菊科--3 种，毛茛科--3 种，蔷薇科--3 种，芸香科--2 种，婆婆纳科--2 种，其他科只有 1 种。根据形态特征：8 个物种（31%）属于裸子植物群，6 个物种（23%）属于裸子植物群，7 个物种（27%）属于中生植物群，5 个物种（19%）属于中生植物群。此外，我们还发现了两种被列入哈萨克斯坦共和国红皮书的植物--Pulsatilla patens (L.) Mill.和 Tulipa patens Agardh.
