Regional Ecological Security Assessment Based on Theory of Ecological Footprint-A Case of Shandong Province
This article is an elementary exploration and practice of applying the theory and method of ecological footprint to assess regional ecological security. The ecological footprint, carrying capacity, ecological deficit of Shandong province from 1995 to 2004 were calculated. Furthermore, the concept and model of ecological footprint pressure index (EFPI) as well as the grade system of regional ecological security was put forward based on ecological footprint so as to analyze the regional ecological security, and some measures to slow down the growth of the ecological footprint and maintain the regional ecological security were put forward at last. The following results were obtained. (1) It is feasible to analyze regional ecological security based on EFPI, which can reflect the degree of ecological security from two respects of carrying capacity and pressure. (2) Among 10 years from 1995 to 2004, the per capita ecological capacity of Shandong province appears to be a reducing tendency, the per capita ecological footprint shows an increasing tendency. The per capita ecological deficit appears an increasing tendency. According to the ecological security grade system measured off by EFPI, the security degree of ecology system belongs to Ⅳ,and it is a worsening state.
