基于生态系统服务的水网乡村生态修复效果评估——以吴江区为例
Evaluation of ecological restoration effect in rural areas with water networks based on ecosystem services:a case study in
[目的]作为人类社会与自然生态系统紧密联系的纽带,生态系统服务可与生态修复工程结合明确区域生态修复的效果。[方法]以典型水网乡村吴江区为例,利用土地利用转移矩阵,分析吴江区土地利用的时空变化特征,以生态系统服务价值变化作为生态修复的效果表征,构建生态修复效果量化评估体系,对吴江区十年来的生态修复效果进行评估和分析。[结果]2012 年-2022 年在经济高速发展背景下建设用地面积增加,耕地、水域面积减少,建设用地主要由耕地和水域面积转入。区域生态系统服务价值由 2012年的 57347万元上升至 2022年的 61189万元,总体呈现上升趋势[结论]生态战略下吴江区 10年修复效果显著,生态系统持续向好,生态效益得到提升。但局部仍存在下降趋势,环境质量有待进一步改善,在未来应增加对其的生态修复手段,促进生态环境发展。
[Objective]As a close link between human society and natural ecosystems,ecosystem services can be combined with ecological restoration projects to clarify the effectiveness of regional ecological restoration.[Method]Taking a typical rural water network in Wujiang District as an example,the land use transfer matrix was used to analyze the spatiotemporal changes in land use in Wujiang District.The change in ecosystem service value was used as a representation of the effectiveness of ecological restoration,and a quantitative evaluation system for ecological restoration effectiveness was constructed to evaluate and analyze the ecological restoration effectiveness of Wujiang District over the past decade.[Result]In the context of rapid economic development from 2012 to 2022,the area of construction land increased,while the area of arable land and water decreased.Construction land was mainly transferred from arable land and water area.The value of regional ecosystem services has increased from 573.47 million yuan in 2012 to 61.89 million yuan in 2022,showing an overall upward trend.[Conclusion]Under the ecological strategy,the 10-year restoration effect of Wujiang District is significant,the ecosystem continues to improve,and the ecological benefits have been improved.However,there is still a downward trend in some areas,and the environmental quality needs to be further improved.In the future,ecological restoration measures should be increased to promote the development of the ecological environment.
