Study on the Evaluation of Land Ecological Security in Anhui Province Based on Ecological Footprint

In this paper, study on land ecological evaluation research from the dimensions of time and space based on the theory of ecological footprint in Anhui province. The study results show that (1) On the time dimension, the per capita ecological footprint of Anhui province showed an increasing trend year by year in 2005-2014; the low level of per capita ecological carrying capacity; the ecological deficit is increasing, but the utilization efficiency of natural resources is increasing year by year. (2) On the spatial dimension, the per capita ecological footprint of Anhui province was different; the cities level per capita ecological carrying level are generally not high, and the regional difference varies considerably, and there are around the city ecological gap in different degree; the differences of resource utilization efficiency in local level cities are relatively large; the level of urban economic development is positively related to the efficiency of resource utilization. (3) From the time dimension and space dimension, although the overall land ecological pressure in Anhui province is not obvious, but in the future economic development, it can not ignore the protection of land ecological environment as before.
