Ecological footprint ( EF) is an important index of ecological carrying capacity. The original EF model is excellent in simplicity, aggregation, comparability, and lifelikeness in presenting results, but short in predictability, configuration, and applicability. To overcome these shortcomings, many researches were conducted to modify and promote the EF model, and developed it from static with single time scale to diversified ones, which included: 1) time series EF model, 2) input-output analysis based EF model, 3) integrated assessment incorporated EF model, 4) land disturbance degree based EF model, and 5) life cycle analysis based EF model, or component EF model. The function of EF as a measurement of ecological carrying capacity was significantly improved, but its accuracy and integrality still need to be advanced.
