Abstract:

In this paper，the basic concept of ecological footprint，ecological capacity and the corrected model of ecological capacity were introduced.In order to estimate the impacts of water projects on ecological capacity，the method by which resource output was regarded as the supply of ecological capacity was adopted based on analyzing the disadvantage of this model.The land use change of ecosystem production after the Liaofang Water Project being completed was analyzed，mainly on the ecological productivity of the irrigation district and the downstream protection areas.At last，the ecological capacity of the Liaofang Water Project was calculated by using the theory and technique of ecological footprint in 2001，ending with a prediction of the ecological carrying capability of Liaofang Water Project district in 2007.The results showed that the ecological capacity will increase greatly after the operation of Liaofang Water Project，the total ecological carrying capability will increase by 79 521 hm2，including 16 735 hm2 reduced by reservoir submergence，the ecological carrying capability of cultivable land will increases by 74 604 hm2.

Key words: Fu River Basin, ecological footprint, ecological capacity, water project
