【摘要】：林业生态建设工程具有重要的经济、生态和社会效益。内蒙古磴口县是林业生态建设工程实施的重点地区,对该区域林业生态建设工程的综合效益进行评价,具有代表性意义。依据评价指标体系构建原则、相关文献资料和当地实际情况,构建磴口县林业生态建设工程综合评价体系;在此基础上,通过时间序列分析,完成1991—2015年磴口县的林业生态建设工程综合效益量化评价。结果表明:在林业生态建设工程评价体系中,经济、生态和社会3个方面所占比重不同,其中,国内生产总值、造林面积、吸收二氧化硫年增加价值、削减粉尘年增加价值及农民人均纯收入五项指标在综合效益评价中权重比例较大;近年来磴口县林业生态建设工程综合效益较1990—1999年期间有所提高,但波动幅度较大,而近年来研究区综合效益趋于稳定并略有上升。磴口县林业生态建设工程在改善区域生态环境、遏制沙化土地扩展等方面的成效相对显著,有效促进了地区经济发展。
