轮耕 Shifting cultivation

(重定向自Shifting Agriculture)

轮耕是耕种的形式,是指在某块土地耕种一段时间,其肥力下降后,即将之荒废休耕,改为耕种其他土地;待原来土地肥力回升后,再重新耕种;类似游牧民族的「逐水草而居」制度。轮耕通常在较不发达国家实行;其能支持的人口有限,若人口上升到某个水平,使休耕的时间不够长,肥力未回复到原来水平,长远肥力就会逐渐下降。

Shifting cultivation is an agricultural system in which plots of land are cultivated temporarily, then abandoned and allowed to revert to their natural vegetation while the cultivator moves on to another plot. The period of cultivation is usually terminated when the soil shows signs of exhaustion or, more commonly, when the field is overrun by weeds. The length of time that a field is cultivated is usually shorter than the period over which the land is allowed to regenerate by lying fallow. This technique is often used in LEDCs (Less Economically Developed Countries) or LICs (Low Income Countries).
