伊春国有林区生态安全动态研究

以伊春市2003～2008年的统计数据为基础,利用生态足迹模型对伊春国有林区的生态足迹、生态承载力进行分析,结果表明:从整体上看,伊春林区生态盈余较多,生态压力指数较小,处于安全状态,但是生态盈余度与生态压力指数整体呈下降趋势;从单个因子来看,草地均处于生态赤字状态,林地对伊春生态盈余的贡献率最大,剔除林地后的生态压力指数处于稍不安全状态。针对伊春生态安全现状,提出将生态足迹作为一种地方生态环境考核指标、通过合理规划来控制牧草地的开发利用、发展低耗能、低污染的绿色环保产业等建议。

The Dynamic Research about Ecological Security in Yichun State-Owned Forest Area

The ecological footprint model is used to analyze the ecological requirement and ecological supply that based on the statistical data from 2003 to 2008 year in Yichun state-owned forest area in this paper.The results show that the ecological surplus is much,the ecological pressure index is small,the ecology in a safe state,but looking from the single factor,the overall trend of the ecological surplus and ecological pressure index is declined on the whole;the forest land in ecological deficit state and contr...
