Naturally restored runoff plots and Leucaena leucocephala runoff plots were built near DDFORS in 2005. The runoff plots are 20 m by 5 m in size, and the slope is approximately 22°. In terms of vegetation coverage, the Leucaena leucocephala runoff plots include Leucaena leucocephala (Lam.) de Wit, Leucaena leucocephala (Lam.) de Wit and Agave sisalana Perr. ex Engelm, and Leucaena latisiliqua (L.) Gillis with the crown removed. The naturally restored runoff plots are categorized into forest land dominated by Leucaena leucocephala, agricultural land, and wasteland. These plots have not undergone any artificial interventions, and the data are for reference only. Runoff volume is obtained by measuring the flow volume in the iron bucket. Sediment concentration is obtained by the same method as mentioned above.", "ds_quality": "", "ds_ref_way": "", "ds_abstract": "
