摘要: The transformation of tropical forests to pasture, crops, and barren land, now rapidly underway wherever occur (Myers 1980; Fearnside 1982; Lanly 1982), contributes the increase in CO2 atmosphere (Woodwell Houghton 1977; Woodwell et al. 1978, 1983a,b; 1983). greatest promise measurement rate change area lies use satellite imagery, available since 1972 LANDSAT series with a resolution about 80 m [NASA 1983, 1983a, Klemas Hardisky 19841. We have developed special technique using imagery from different times make direct measurements changes forests. was for Maine tested Washington 1983a). report here an application moist state Rondonia Brazilian Amazon (Fig. 13.1).
