摘要
吉林省西部地区由于气候和人类活动的影响,土地退化严重,表现为土地盐碱化,土地沙化,土地贫瘠化和草原退化。退化土地面积已超过280万hm2,约占该区总面积的60%。恶劣的生态环境已经严重影响了当地的经济发展,为使吉林西部地区走上可持续发展的良性循环轨道,本文分析了沙棘在吉林省西部退化土地治理中的生态功能、经济价值以及综合利用价值,认为大力发展沙棘生态经济林是该区改善生态环境,推动经济发展的必然选择。
Land in the west of Jilin province degenerated heavily caused by climate and human＇ s abilities, including saline-alkalized, sandy desertification and infertile soil and grassland degration. Area of the degraded land was over 2.8 million hectare, accounting for 60% of total area of Jilin province. To progress sustainable development of eco-economy in the west of Jilin province, ecological function, economic value and multipurpose utilization of seabuckthorn was introduced, and seabuckthorn eco-economic forests should be further constructed in the west of Jilin province.
