Özet (Çeviri)
Mid-Black Sea Region (Yesilxrmak-Melet çayı-Kel- kit vadisi) has various mass of vegetation occured under the contidion of climate and soil releif. With in the Central Black Sea Region are located Yeşilırraak in the west, Melet river in the east, Kelkit çayı in the south More than half of the observation Field is on moist Forests. In this very moist air of Black Sea province torrid and rainy zone caused a convenient possibility for the emergence of dense moist forests» The expanding area of moist forests in Canik mointains are the skir.ts facing the north of the mointainous hills. The moist forests, dominantly formed places, particularly on the east side of ttoe coastline starts from very near the Black Sea and goes on towards the south covering densely all the platoes and the hills and the mointainous slopes, facing the north. The faces of the mountains parallelig to the sea, particularly northern slopes are covered with dense grooves, the slopes facing the south covered dry wood lands-clear off ground vegetation though preserving thick moist forests. The passage to the area the dry forests located between coastal mountains and the Kelkit valley through the moist and thick forests on slopes, which, facing the north of the Ganik mountains249 piving their places to the rare copses on the hills, thickly wood on the streams, and wide implanted rocky areas, are now demolished. These forests -formed of the dry. woods and sharply diverse from the moist forests by their poor sort, lack of surfatre vegetation and loosely appearance. In our observation field part of dry forests take less place than moist forensts but more place than the place of maki and preudomaki. This is closely related to the morphologial feature of the province. On the north of the groove of Kelkit valley, passing of summit lines caused norrowing the areas of forests while widening of the moist forests. In this part, located on the south of Canik Mountains, near by Karınca Mountains on the west, Igdir Mountains on the east, the dry forests are widely scattered every where. In our observation field the expanding areas of psendo-makis are the border banks of the sea where forests have been destroyed. And the formation of pseudo-makis emerges along the valleys to the sea. The expanding areas of pseudo-makis are of the expan ding areas of the moist forests everywhere, which are the northern faces of the coast parts. The widely scattered places of pseudo-makis are the monuths of valleys where the rivers pour into the sea, and the places where Gürgen, Kayın forests cannot approach250 the coast. The destroyed areas of these forests are the parts of heavy farming and pseudo-makis. The coastal parts of our observation field are departed into two parts as the east and the west hal ves of the coastal region owing to the climatic characteristically seen in vegetation formation of the area. The formation of pseudo-makis, located on the c coastline is influenced by this re -formation in accor dance with climate. Because, owing to the direct inf luence of the relief conditions, for the mountains, on the east side of the observation field mounts up right near the coastline, the moist, hot, and rain conditions show seperation from the west. Our fourth observation field is maki-field. Maki- formation is seen on the lower and southern slopes of Kelkit valley and the mouths of lower valleys along these slopes, and on the hilly platoes of İğdır moun tains southern skirts bordering Kelkit valley groove maki covers the destroyed regions and the pround sur face of dry forests particularly Kızılcam forests. The places on which plenty of makis exist are the Karınca mountains and the south skirts of İğdır mountain and the regions between Erbaa and Niksar river-bus in. They are, at the soma time, the hottest and the most suitable places of the region in respect of251 sunbathing. In fact, this is the main reason why the maki elements of Mediterrenean origin which reguire much light and temperature snuggle up far here. Though, in the formation of vegetation of the observation field, the real part is played by the physical conditions, the effect of man is also important. There fore, the present borders of the various vegetation in the region are beyond being natural. For thausands of years human being has intervened in the natural vegetation in this resident field, and has caused the field of forests to norrow. The place of destroyed forests has been covered by psido-maki on the coast, and maki -formation somewhat limited in mid-lands. In our observation field the main elements are formed by Kayın, Gürgen, Kestane, Ladin, Sarıçam, Kıızıl- çam, dişbudak, titrek kavak; among these Kayın is more widely spread out.
