摘　　要：修复受损生态系统是提升生态系统稳定性、可持续性的重要举措,科学判断分析生态系统修复的优先区,对加强生态系统的管护有重要意义。以浙江省德清县的森林修复为例展开研究,识别出潜在森林修复区后,评估生态系统服务收益与修复成本,利用修复机会优化工具(ROOT)来确定不同需求目标情景下最具效益的优先修复区域。结果表明:(1)研究区中潜在修复区面积约6497.5 hm^(2),其中森林退化区占77.7%,森林转化区占12.6%,处于较大坡度上的农田与种植园占9.6%。(2)研究区的优先修复空间选择效益评估结果中,以获得更多土壤保持功能为目标的需求情景,表现最为突出,仅需投入10.0%的修复成本代价,便可获得47.7%的潜在土壤保持功能。(3)不同目标需求情景下的土地类型修复次序也存在差异,以获得土壤保持与洪水调蓄功能为目标时,需重视森林与灌丛生态系统质量的提升;而以减少N、P流失为目标时,则需重视促进农田向森林与灌丛生态系统的转化。文章提出的“修复区识别—修复效益评估—高效益修复区优选”流程与方法,可为研究区及其他地区生态恢复工程实践提供参考借鉴。Restoring damaged ecosystems is an important measure to improve the stability and sustainability of ecosystem services.Analyzing the priority areas for ecosystem restoration is of great significance to scientifically support ecosystem management and protection,Taking forest restoration in Deqing County as an example,this study identifies the potential forest restoration areas,assesses the ecosystem service benefits and restoration costs,and then uses restoration opportunity optimization tool(ROOT)to determine the most beneficial priority restoration areas under different demand target scenarios.The results showed that:1)The area of potential restoration area in the study area is about 6497.5 hm^(2),of which 77.7%is forest degradation area,12.6%is forest transformation area,and 9.6%is farmland and plantation on large slope.2)In the evaluation results of priority restoration space selection,the demand scenario with the goal of obtaining more soil conservation functions is the most prominent,which shows that it takes only 10.0%of restoration cost to obtain 47.7%of potential soil conservation functions.3)The restoration order of land types under different target demand scenarios is also different.To achieve soil conservation and flood storage functions,it should pay more attention to improving the quality of forest and brushwood ecosystem.It should pay more attention to promoting the conversion of farmland to forest and brushwood ecosystem,in order to reduce nitrogen and phosphorus output.The process and method of"identification of restoration areas-assessment of restoration benefits-optimization of high benefit restoration areas"can provide scientific guidance for the practice of ecological restoration projects in the research area and other areas.
