Рассмотрено применение метода фитоиндикации и космоснимков среднего разрешения для решения гидрологических задач на заболоченных территориях таежной зоны в Западной Сибири. На примере типичного для таёжной зоны малого водотока Ключ выполнен анализ гидрологических условий. Показано, что тенденция развития процесса болотообразования в таёжной зоне сохранится в ближайшей и среднесрочной перспективе. The application of the method of phytoindication on the basis of the analysis of space pictures of average resolution for the decision of hydrogeological tasks in the wetlands of the taiga zone of West Siberia is considered. By the example of a little spring «Kluch», typical for the taiga zone, a spatial interdependence between vegetation and hydrogeological conditions in the wetlands is established, which permits to use the method of phytoindication to solve different hydrogeological tasks in hard-to-reach regions of West Siberia. While choosing the phytoindicative indicators, the morphological and ecological characteristics of wetland plants and the character of their association with phytocenoses are taken into account. According to morphological characteristics, a classification of wetland plants of the central part of the taiga zone of West Siberia is developed. For the spring «Kluch» the morphometric characteristics are established with the help of phytoindication. Also it is demonstrated that the catchment basin of this stream is 1.7 times bigger than that stipulated in Rosgidromet materials. As a result, the values of surface run-off of the spring «Kluch» have changed significantly. Besides this, the more correct values for wetland square, including treeless and forest wetland systems, have been obtained. With a glance of the characteristics obtained, an analysis both of water balance structure and temporary alterations of its elements is provided. The analysis discloses the alteration in water regime of the territory under study which is characterized with a certain decrease in the surface run-off in November and December, April-June and increase in August-September. The alteration mentioned above is connected with a statistically significant decrease in general humidification of the catchment area in April, gradual augmentation of evaporation in fall period, growth in duration of transitional fall-winter period and correspondent shortening of moisture supply in snow cover in November-December. In whole, in the nearestand medium-term prospects, the conditions favorable for the development of wetland-formation processes in the warm period of the year and the improvement of conditions necessary to the existence of vegetation generally exacting to warmth are going to continue which, in a rather severe environment leads to intensification of peat accumulation.
