Ecological disturbance index

This data represents a dimensionless ecological disturbance index, as the ratio of ecological succession and disturbance recurrence interval times the fraction of the area disturbed in any event. Small values of the ecological disturbance index represent decreasing proportions of time when disturbed/recovering habitats are present.

本数据集表征一项无量纲生态干扰指数（dimensionless ecological disturbance index），其计算公式为生态演替时长与干扰重现期（disturbance recurrence interval）的比值，乘以单次干扰事件内受干扰区域的面积占比。该生态干扰指数的取值越小，则存在受干扰或恢复中生境的时间占比越低。
