Abstract

Abstract: To evaluate the ecological status in Yonghe river basin, ecological footprint model was used to calculate its ecological demand and supply in 2016. The results showed that its per capita ecological footprint was 0.499 12 hm², the ecological carrying capacity was only 0.265 96 hm²and the per capita ecological surplus was -0.233 16 hm² with -0.467 14 of safety index. The ecology of the basin was in unsafe state, to ensure the high quality of development in future, it was important that current extensive way of consumption be changed to save and protect local resources; New and high technologies should be developed to increase the production of natural resources; It should be paid more attention to the quality rather than the quantity of the population; Existing resources should be used efficiently and rationally.

Key words: ecological footprint, Yonghe river basin, ecological condition, safety
