[Objective] The aim was to study the ecological footprint and sustainable development in Karst Area. [Method] By dint of statistical data of Anshun City in 2008, the ecological footprint of Anshun City was calculated. The sustainable development of ecological system in Anshun City was analyzed from the angle of balance of supply and demand. [Result] The per capita ecological capacity was 0.447 8 hm2/cap in 2008, per capita ecological footprint was 2.309 0 hm2/cap, and ecological surplus of deficit was 1.861 2 hm2/cap. It meant the EF of the present region in terms of human activities had already exceeded the benchmark of system ecological carrying capacity. The supply of natural resources can't fully meet people's needs, and land use was unsustainable. The sustainable development of Karst area can be realized through changing people's production and life consumption model, building resources-saving social productive consumption system, depending scientific and technological development, improving production technology, using new technology, improving resources utilization effect and developing recycle economy.
