Probing time series vegetation data for evidence of succession, The results suggest that the recording period is sufficiently long for trends to be detected. A dominant trend depicts density changes as simple monotone functions of time. Other lesser trends signify cyclic changes of different lengths. The fact that a dominant monotone trend exists is interpreted as evidencè of succession.作者: 最有利 時(shí)間: 2025-3-22 16:20
