Forest ecologists have been more concerned than agronomists with the inner mechanisms of natural and artificial ecosystems. 森林生態(tài)學(xué)家比農學(xué)家更關(guān)心天然生態(tài)系統和人工生態(tài)系統的內部機制。
Within great latitudes, the artificial ecosystem of Bio2 ran its own course, but when it veered toward a runaway state, or stalled, the biospherians nudged it. 生物圈二號這個(gè)人工生態(tài)系統極大限度內循自己的線(xiàn)路運行，但是當它滑向失控的狀態(tài)，或者停止運轉時(shí)，生物圈人可助予一臂之力。
