基于生态足迹的安徽省土地生态安全评价研究

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

  • 摘要: 利用生态足迹理论从时间和空间维度开展安徽省土地生态评价研究。结果表明:(1)时间维度上,2005-2014年安徽省人均生态足迹整体呈现逐年上升趋势;人均生态承载力水平较低;生态赤字总体呈上升趋势,但是对自然资源的利用效率逐年提升。(2)空间维度上,安徽省各地级市人均生态足迹差异较大;各地级市人均生态承载水平普遍不高,各地区差异比较大,各地市出现不同程度的生态缺口;对资源利用效率差异较大,城市经济发展水平与资源利用效率呈正相关。(3)不论从时间维度还是空间维度,安徽省整体虽然目前面临土地生态压力不明显,但是在未来的经济发展中,依旧不可忽视对土地生态环境的保护工作。

     

    Abstract: 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.
