中文摘要	植被恢复与重建是遏制沙化过程的有效措施,生态恢复的最终目标是使退化生态系统恢复并维持生态系统的服务功能。基于生态系统服务价值的植被恢复工程效益分析研究有助于提高植被恢复工程的评估水平,以及植被恢复工程的进一步开展。该研究采用市场价值法、替代市场法、影子工程法、碳税法等手段对科尔沁沙地4种典型退化草地恢复方式下的生态系统服务经济价值进行了估算。结果表明,4种恢复方式下,有机质生产价值和生态系统碳贮存价值排序为北京杨(Populus*beijingensis)围草地>樟子松(Pinus sylvestris var. mongolica)疏林草地>榆树(Ulmus pumila)疏林草地>撂荒草地;土壤保持价值和营养物质循环价值排序为北京杨围草地>榆树疏林草地>樟子松疏林草地>撂荒草地;四项生态系统服务的总价值排序为北京杨围草地(8109.78 yuan·hm~(-2)·a~(-1))>樟子松疏林草地(7774.52 yuan·hm~(-2)·a~(-1))>榆树疏林草地(5941.34 yuan·hm~(-2)·a~(-1))>撂荒草地(1893.46 yuan·hm~(-2)·a~(-1)),与撂荒草地比较,3种恢复方式均显著提升了生态系统服务价值,平均增幅为57.92%,其中土壤保持价值与生态系统碳贮存价值占总价值的比例较高,分别为11.38%~12.78%,82.30%~83.28%。综上,科尔沁沙地东南缘营造防护林和稀疏林地有效提高了生态系统服务价值,是较适合降水不足和土壤有效营养元素缺乏的科尔沁沙地的植被恢复模式。
英文摘要	The restoration and reconstruction of vegetation is effective measures to curb desertification process, China has implemented large-scale vegetation restoration project, and the ultimate goal is to make the restoration of degraded ecosystem and maintain ecosystem services. The benefit analysis of vegetation restoration project based on ecosystem services value will improve the evaluation level of vegetation restoration project, and will contribute to the further development of vegetation restoration project. By using the methods of opportunity cost approach, shadow price method, market price replacement cost method, and carbon tax method, we systematically studied the value of ecosystem service of different grassland restoration approaches in Horqin Sandy Land. The results showed: (1) The value of organic matter and ecosystem carbon storage of four different grassland restoration approaches was as follow: grassland fenced by Populusbeijingensis shelter forest>Pinus sylvestris var. mongolica scattered grassland>Ulmus pumila scattered grassland>abandoned grassland; (2) The value of soil conservation and entire nutrients (N, P, K) accumulation of four different grassland restoration approaches were as follow: grassland fenced by Populusbeijingensis shelter forest>Ulmus pumila scattered grassland>Pinus sylvestris var. mongolica scattered grassland>abandoned grassland; (3) The total value of the above typical ecosystem services of four different grassland restoration approaches was as follow: grassland fenced by Populus*beijingensis shelter forest (8109.78 yuan·hm~(-2)·a~(-1))>Pinus sylvestris var. mongolica scattered grassland (7774.52 yuan·hm~(-2)·a~(-1))>Ulmus pumila scattered grassland (5941.34 yuan·hm~(-2)·a~(-1))>abandoned grassland(1893.46 yuan·hm~(-2)·a~(-1)), compared with CK, all three grassland restoration enhanced the value of ecosystem services, with an average increase of 57.92%,among them, the proportion of soil conservation value and carbon storage value of ecosystem were higher, which were 11.38%~12.78% and 82.30%~83.28%, respectively. The protection forest and sparse planting of sand land in the southeast Horqin Sandy Land have restored the vegetation of sandy land and improved the value of ecosystem service effectively, which is more suitable for the vegetation restoration mode under insufficient precipitation and lack of available nutrient elements in the southeast Horqin Sand Land.
