自發演替

自力演替（英語：autogenic succession）是指由生態系內的生物因素驅動的演替，雖然自力演替的機制長期以來一直存在爭議，但人們很早就意識到了生物演替過程中起到的作用。^[1]^[2]^[3]目前，學界主流的共識是促進、耐受和抑制機制都對自力演替有作用。^[4]演替的概念通常與植被和森林群落相關，但它也適用於更廣泛的生態系。與此相反的概念是外力演替，它是指由生態系的非生物因子驅動的演替。^[5]

作用機制

植物本身（生物組分）可以導致演替發生。

葉片捕捉日光
碎屑的產生
水分和養分吸收
固氮
人為氣候變遷

植群之變化，由生物本身之作用所產生者，稱為自力演替，而自力演替屬於初級演替，包括生態系中生物、土壤及微氣候之變遷。^[6]

促進

改善場地因素，如增加有機質

抑制

阻礙物種或生長
