Abstract

Abstract: Based on Linxiang Statistical Yearbook （2010, 2018）, the ecological footprint of Linxiang City was analyzed by using the ecological footprint method in combination with the relevant statistical data of the territorial space plan of Linxiang City （2019—2035）.The results showed that the per capita ecological footprint of Linxiang City showed an obvious upward trend. By calculating the local actual output of each biological resource, the local yield factor was obtained, and the ecological carrying capacity more in line with the actual local level was caculated, showing that with the development of science and technology level, regional total ecological capacity increased. But the increase in population and the expansion of urbanization made the per capita ecological carrying capacity decrease. It was found that controlling population growth, strengthening the protection of cultivated land and water area, improving energy efficiency and reducing pollutant discharge can effectively alleviate the regional ecological deficit of Linxiang City.

Key words: ecological footprint, ecological carrying capacity, yield factor, Linxiang City
