Does the hum an load stay w ith in global carrying capacity? T he eco logical foo tp rin t concep t has been designed to an sw er th is question and estim ate m an s impact on natu re. T he eco logical foo tp rin t of any defined population ( from a single individual to a w ho le city o r coun try) is the to tal area of eco logically p roductive land and w ater occup ied exclu sively to p roduce all the resou rces con sum ed and to assim ilate all the w astes generated by population. T he eco logical foo tp rin t m ethod p resen ts a simp le fram ew o rk fo r national natu ral cap ital accoun ting. T he concep t of eco logical foo tp rin t and its calcu lation m ethod is in troduced in th is p ap er. T he p ap er a lso ana lyses the advan tages and d isadvan tages of the eco log ica l foo tp rin t model, and addresses the types of eco logically p roductive lands. T he article calcu lates and analyses the eco logical foo tp rin t of Gan su p rovince in 1998. T he eco logical foo tp rin t ledger is com po sed of th ree m a in sect ion. T he first ledger is ba sic b io t ic resou rces con sump tion including its byp roducts, the second is energy con sump tion, the th ird is t rade ba lance. T rade ba lance th rough m o re deta iled t rade flow ana lyses can m itigate the influence of impo rt and expo rt p roduct on con sump tion variation s. Based on the eco logical foo tp rin t concep t and analysis fram ew o rk, hum an con sump tion can be compared w ith regional2level natu ral cap ital p roduction u sing ex isting data. In the case of Gan su p rovince, the eco logical deficit of Gan su is 01564 2 hm 2 per cap ita. Simp lification of calcu lation m ethodo logy to certain ex ten t resu lts in over2op tim istic estim ates. F inally, the eco logical foo tp rin t model s advan tages and disadvan tages are iden tified. Eco logical foo tp rin t index is an excellen t aggregate index that connects m any issues of su stainab ility, developm en t and equ ity. T he model can reveal the ex ten t to w h ich local carrying capacity has been exceeded and allow s a cum u lative app roach to impact analysiṡ T he u se of eco logical p roductive area as a num eraire, rather than money o r energy, m akes the foo tp rin ts easy to be understood, and also perm its p rovocative calcu lation s. T he lim itation s of the model is that it doesn t include several impo rtan t issues, w h ich are even directly related to land u se: land areas lo st to b io logical p roductivity lo ss of land becau se of con tam ination, ero sion and u rban harden ing and dissertation (especially in no rth2 w estern Ch ina).
