Abstract

The originality of any flora is characterized by various indicators amongwhich an important role is played by the indicators of specific wealth, systematic structure, ecological structure and structure of vital forms allowingto resolve a number of practical issues.The carried-out ecological analysis of flora of the region has shown avariety of ecological types. The basis of flora of the Zharkent lowland ismade by angiospermous plants. 5 ecological groups of plants, namely kserofit, mezokserofit, mezofit, kseromezofit and gigrofit are defined. Kserofit(165 types-28/49 %) – plants of the dry earth because of not sufficiencyof moisture are given by firmness to soil and atmospheric droughts. Theyhave various devices to conditions of a lack of moisture: strongly developed root system which is water carrying out system. Ephedra distachya L.,Ceratocarpus arenarius L., C. utriculosus Bluk., Camphorosma lessingii Litand others. Mezokserofit (150 types – 25, 90%) – are in sand, clay, mountain territories, and also woody places. It is Ceratocephala falcata (L.) Pers.,C.orthoceras DC., Papaver pavoninum Schrenk, Acanthophyllum pungens(Bunge) Boiss. and others.Mezofit (135 types – 25,90%) – it is adapted to life of the water provided environment. These are such types as Equisetum arvense L., Thalictrum flavum L., Th. isopyroides C.A. Mey and others. Ephemeral plants andefemeroid [118] which form spring flora belong to the same group. Kseromezofita (121 types – 20,89%) – in flora of the Zharkent lowland ecological type between mezofit and mezokserofit. Belong to kseromezofitaDelphinium camptocarpum Fich. et C.A.Mey., Hypecoum parviflorumKar. et Kir., H. trilobum Trautv., Nanophyton erinaceum (Pall.) Bunge andothers. Gigrofita (8 types – 1,38%) – these plants are lived in places withhigh humidity of air and soils. Pronounced gigrofita of flora of valleys of therivers – grassy plants: Polygonum amphibium L., Cicula virosa L., Scirpustabernaemontani C.C.Gmel., S. triquetriformis (V.Krecz) Egor..Between biological types according to K. Raunkiyer gemikriptofita(263 types or 45,42%), kriptofita (30 types – 5,18%), and terofita (203types or 35,06%) prevailing in flora of the studied territory. According toI.G. Serebryakov the greatest number of types – grassy polikarpik (285types or 49,22%), the greatest part of types belong rhizomes to a grassysubclass of polikarpik. The majority of shrubby and semi-shrubby typeskserofitny type, it characterizes presence of an element of the desert atflora of this area. The analysis of a vital form of the Zharkent lowland hasshown a variety of a vital form of the prevailing plants – rhizomatous polikarpik and monokarpik. Plants grow and develop under the influence ofa complex of factors, the defiant adapting reactions. The main incentive ofevolution of flora is fight against humidity, has proved formation of historyof modern flora of the globe of different areas.Key words: flora, the sort, look, kserofit, mezokserofit, mezofit, kseromezofit, gigrofit.
