植物在生长、发育和衰亡的过程中,与外界环境(气候、土壤、山岳、湖海等),有着密切的联系。通常称植物是反映气候变化的温度计。另一方面看,“过去又是了解现在和预测未来的钥匙”。因此,对过去植被发展模式的建立,有助于研究气候的波动。为了达到恢复植被、了解气候的目的,即需 Plants in the process of growth, development and decline, and the external environment (climate, soil, mountains, lake, etc.), are closely linked. Plants are commonly referred to as thermometers that reflect changes in the climate. On the other hand, “the past is the key to understanding the present and forecasting the future.” Therefore, the establishment of past vegetation development model helps to study climate fluctuations. In order to achieve the goal of restoring vegetation and understanding the climate, we need it
