   <abstract xml:lang="ru">
    <p>В работе приводятся результаты исследования поведения ионосферных параметров: полного электронного содержания I(t) и электронной концентрации в максимуме слоя F2 Nm — над Алма-Атой (Казахстан) [43.25° N; 76.92° E] за 1999–2013 гг. Рассматриваемый временной интервал охватывает разные уровни солнечной активности. Показано, что при F10.7&gt;175 летом и при F10.7&gt;225 зимой наблюдается эффект насыщения, т. е. с ростом уровня солнечной активности значения I(t) не увеличиваются. Наблюдаемая нелинейная зависимость полного электронного со¬держания ионосферы от потока радиоизлучения Солнца F10.7 является следствием нелинейной зависимости солнечного ультрафиолетового излучения от потока радиоизлучения Солнца. &#13;
Исследование изменчивости параметров среднеширотной ионосферы при разных уровнях солнечной и геомагнитной активности показало, что стандартное отклонение ç(x) и средний сдвиг Xave флуктуаций I(t) и Nm относительно спокойного уровня слабо зависят от уровня солнечной активности, а зависимость от геомагнитной активности значительна при F10.7&lt;100.</p>

    <p>The paper presents the results of a study of the behavior of ionospheric parameters of the total electron content, I(t), and electron density in the maximum F2 layer, Nm, over Almaty (Kazakhstan) [43.25° N; 76.92° E] in 1999–2013. The time interval under study covers different solar activity levels. We have shown that at F10.7&gt;175 in summer and at F10.7&gt;225 in winter there is a saturation effect, i.e. with increasing solar activity level values of I(t) do not increase. The observed nonlinear relationship between the total electron content of the ionosphere and the solar radiation flux F10.7 results from the nonlinear relationship between the solar ultraviolet radiation and the solar radiation flux.&#13;
The study of the variability of the mid-latitude ionosphere parameters during different solar and geomagnetic activity levels has shown that the standard deviation ç(x) and average shift Xave of I(t) and Nm fluctuations relative to the quiet level weakly depend on solar activity, but greatly depend on geomagnetic activity when F10.7&lt;100.</p>
