Комплексное исследованиe фрагментов ценопопуляции Chamaecytisus Ruthenicus (Fisch. ex Wol.) Klask. в лесопарковой зоне г. Екатеринбурга

Abstract

Проведено комплексное исследование фрагментов ценопопуляций ракитника русского (Chamaecytisus ruthenicus) в светлохвойных насаждениях лесопарка им. Лесоводов России г. Екатеринбурга Свердловской области на основе их онтогенетического спектра, индексов восстановления, замещения и возрастности, плотности, категорий жизненного состояния, морфологических и агрохимических параметров. Почвы в лесопарке им. Лесоводов России имеют среднесуглинистый гранулометрический состав, благоприятную порозность, среднюю обеспеченность почвенных горизонтов доступным фосфором (Р2О5) и, как следствие, благоприятные водно-физические свойства для произрастания ракитника русского. Наличие в подлеске данного вида и состояние его фрагментов ценопопуляций свидетельствуют о типичном составе древесных видов лесопарковой зоны г. Екатеринбурга. В исследуемом лесопарке Chamaecytisus ruthenicus является одним из соэдификаторов коренных типов леса наряду с рябиной обыкновенной, малиной обыкновенной, черемухой обыкновенной, ивой козьей, розой иглистой и другими растениями. Изученные фрагменты относятся к типу молодых нормальных ценопопуляций с полночленным спектром. Несмотря на антропогенное воздействие, ценопопуляция ракитника русского в лесопарковой зоне г. Екатеринбурга устойчива и способна к самоподдержанию. Для сохранения вида необходимо проводить постоянное наблюдение за устойчивостью и динамикой природной ценопопуляции в связи с нерегулируемой рекреационной нагрузкой. Исследование процессов позволит сделать прогноз их развития и предложить природоохранные мероприятия для сохранения вида. A comprehensive study of fragments of Chamaecytisus ruthenicus cenopopulations in light coniferous plantations of the forest Park was conducted. Russian foresters of Yekaterinburg Sverdlovsk region on the basis of their ontogenetic spectrum, indices of recovery, replacement and age, density, categories of vital state, morphological and agrochemical parameters. Soils in the Park. In Russian forestry have a medium loamy granulometric composition, favorable porosity, medium availability of soil horizons with accessible phosphorus Р2О5 and, as a consequence, favorable water-physical properties for the growth of the Scotch broom Russian. The presence of this species in the undergrowth and the state of its fragments of cenopopulations indicate the typical composition of woody species of the forest Park zone of Yekaterinburg. In the forest Park under study Chamaecytisus ruthenicus is one of the coeditors of the indigenous forest types along with rowan, raspberry, cherry, goat willow, rose and other plants. The studied fragments belong to the type of young normal full-spectrum cenopopulations. Despite the anthropogenic impact cenopopulation broom Russian in a forested area in Yekaterinburg is stable and capable of self-support. To preserve the species it is necessary to constantly monitor the stability and dynamics of natural cenopopulation, due to unregulated recreational load. Study of the processes allows to make a forecast of their development and to propose environmental measures for the conservation of the species.
