Analysis on Ecological Footprint and Ecological Carrying Capacity in Caohai of Dianchi Lake Catchment

Calculation results of ecological footprint and ecological carrying capacity show that the ecological footprint in Caohai is 2.728 hm2 for per capita,the ecological carrying capacity is for 0.058 hm2 for per capita.The ecological deficit is up to 2.670 hm2 for per capita.From the dynamic changes of view,the ecological footprint for per capita rose gradually from 2000 to 2004,while the ecological carrying capacity for per capita went down slightly.It results ecological deficit increased gradually.Compared with the Kunming City and Yunnan Province,the ecological footprint of Caohai was higher,while the ecological carrying capacity was lower and thus the ecological deficit is much larger than that of Kunming and Yunnan Province.At the same time,based on the calculation results of ecological footprint and ecological carrying capacity,the ecological optimum population of Caohai can be estimated.
