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 />

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 />
