摘 要: | 为了解退耕还林工程带来的效益,基于2001—2014年陕南地区退耕还林工程的现状,参考国内外有关效益评价指标体系的原则和方法选取指标,建立陕南退耕还林评价指标体系,应用层次分析法确定各项指标权重,利用效益评价模型从生态、经济、社会3个方面对退耕还林的综合效益进行定量评价。结果表明,陕南三市退耕还林效益指数曲线均呈上升趋势,说明退耕还林效益正逐渐、稳定地显现,尤其从2004年开始,退耕还林的效益显现尤为明显,增速加快。汉中、安康、商洛的综合效益较接近且呈现出同步上升的趋势,截至2014年,汉中市退耕效益最高,综合效益指数为0.6630,安康市居中为0.4985,商洛市最低为0.4260。陕南地区退耕还林综合效益逐步显现且仍将保持平稳增长的态势。

| |
Abstract: | To understand the benefits of returning farmland to forest, based on current situation of the project of returning farmland to forest in southern Shaanxi in 2001-2014, the author selected indicators with reference to domestic and foreign benefit evaluation index system and method, and established an evaluation index system of returning farmland to forest in southern Shaanxi. The author determined the weighing of the indexes by using analytic hierarchy method, and quantitatively evaluated the comprehensive benefit from ecological, economic and social aspects by utilizing the benefit evaluation model. The results showed that the benefit index curve of returning farmland to forest in three cities of southern Shaanxi had a rising trend, the effect of returning farmland to forest appeared gradually and steadily, especially since 2004. The comprehensive benefits of Hanzhong, Ankang, Shangluo showed a trend of simultaneous growth, but by the end of 2014, the highest efficiency of returning farmland was 0.6630 in Hanzhong, 0.4985 in Ankang, and 0.4260 in Shangluo. The comprehensive benefit of returning farmland to forest would mai tain a steady growth trend in southern Shaanxi in the future. |
