Estudio ecologico integrado de la cuenca del
Rio Manso Superior ( Rio Negro, argentina ) .
I Descripcion general de la cuenca.
Bosque andino - patagonico = 4.9 % of total tierras
forestales of argentina or 0.8 % of total argentinas.
P(h,t) = P(ho,to) [ 1 + K1 (h-ho) + K2 (t-to) ]
P(ho,to) = precipitation at base station at head to ( mm )
h-ho = diff in altitude ( m )
t-to = diff in longitude west between stations ( m )
K1 = relative altitudinal gradient ( m-1 )
K2 = relative longitudinal gradient ( m-1 )
ppt. increases 68.3 % per km of altitude and 5.2 %
per km. of distance.
P(h,t) = P(ho,to) [ 1 + 6,827 x 10-4 (h-ho) + 5,213 x 10-5 (t-to) ]
Pampa Linda - alt. 845 m. 5 yrs of record.
Temp. media 6.8°, ppt 1846, días con heladas 153,
días con ppt. 183, temp. mat. absoluta 31.8°, minino
-18°. Veloc. media del viento 7.5 km/h. all months
have below-freezing temperatures. The frostfree. of
Holdridge = 7.2°C. Ppt. 1846 mm. Cociente de
evapotranspiración / Potencial = 0.230/230. Pampa Linda lies
somewhere between Bosque húmedo ( Musardi ) and
