FORESTRY BELTS SILVICULTURE AND CINEGETICS REVIEW XVII/30/2012<br />

taking into consideration the fact that the width<br />

established for the shelterbelts is of 10 m, the area<br />

covered with forest shelterbelts was determined within<br />

the two l<strong>and</strong> use categories. Thanks to the GIS work<br />

technique being applied, within the two geographical<br />

units the area corresponding to each l<strong>and</strong> use category<br />

was divided by solution types, counties <strong>and</strong><br />

administrative-territorial units, the results being<br />

presented in tables.<br />

It must be reminded the fact that during this stage the<br />

l<strong>and</strong> with s<strong>and</strong>s <strong>and</strong> s<strong>and</strong>y soils also the alluvial soils<br />

(generally s<strong>and</strong>y) within the two geographical units<br />

were not analyzed because they required a different<br />

approach. Based on punctual field investigations<br />

carried out, it resulted that the surface of terrains with<br />

s<strong>and</strong>s <strong>and</strong> s<strong>and</strong>y soils which in the actual records<br />

represent approximately 135000 ha, is in reality much<br />

higher – approximately 255000 ha – resulting an<br />

extension of 47%, that imposes the necessity to<br />

establish more precise (by modern methods applied in<br />

the field) the areas occupied by those. Regarding the<br />

alluvial soils, they cover an area of 640000 ha in the<br />

Danube Plain while in the Dobrogea the covered area<br />

is 92000 ha, totalizing an area of 732000 ha.<br />

Danube Plain<br />

In the Danube Plain resulted a total area of forest<br />

shelterbelts network of 70226 ha (2.5 %), which<br />

protects a total area of agricultural l<strong>and</strong> of 2806989<br />

ha. The network that protects the arable l<strong>and</strong> has<br />

67366 ha (2.5 % of the total of 2693655 ha), while the<br />

network that protects the permanent pastures has 2860<br />

ha (2.52 % of the total of 113334 ha).<br />

The surface covered by the network, its percentage<br />

<strong>and</strong> the total area protected within the permanent<br />

pasture l<strong>and</strong> use category, on the five solution types,<br />

is the following (Table 1):<br />

The area covered by the network, its percentage <strong>and</strong><br />

the total protected area within the arable l<strong>and</strong> use<br />

category, on the five solution types, is the following<br />

(Table 2):<br />

Within the permanent pasture l<strong>and</strong> use category the<br />

distribution of the area of shelterbelts network at the<br />

county level reflects a variation ranging from under 50<br />

ha (Vrancea) up to over 240 ha (Galaţi).<br />

Within the arable l<strong>and</strong> use category the distribution of<br />

the area of shelterbelts network at the county level<br />

reflects a variation ranging from under 1300 ha<br />

(Vrancea) up to over 8000 ha (Călăraşi).<br />

Dobrogea<br />

In Dobrogea resulted a total area of forest shelterbelts<br />

network having 16986 ha (2.5 %), that protects a total<br />

area of agriculture l<strong>and</strong> of 679958 ha. The network<br />

that protects the arable l<strong>and</strong> has 14998 ha (2.5 % of<br />

the total of 600109 ha), while the network that<br />

protects the permanent pastures has 1988 ha (2.49 %<br />

of the total of 79849 ha).<br />

The area covered by the network, its percentage <strong>and</strong><br />

the total protected area under the permanent pastures<br />

l<strong>and</strong> use category, on the three solution types, is the<br />

following (Table 3):<br />
