摘　　要：国土整治与生态修复对保障区域生态质量、优化生态安全格局和提升生态系统服务价值有积极的促进作用。定量化测算国土综合整治与生态修复对区域生态质量的影响是领域的研究热点和难点。以广西壮族自治区贺州市为例,提出了国土综合整治与生态修复对区域生态系统服务价值的影响评估方法,主要结论如下:(1)不同地类由于其质量不同,单位面积生态系统服务价值差距较大,研究提出了基于地类质量的单位面积生态系统服务价值确定方法,并据此测算了各地类通过整治修复质量的提升潜力;(2)贺州市整治修复前生态系统服务总价值为411.80亿元,经过评估,整治修复后生态系统服务总价值可以增加到458.06亿元,增加比例为11.23%。贺州市林地生态系统服务价值增加潜力最大,其次是草地、耕地。生态系统服务价值增加潜力在空间上呈现了东西两翼高于中部、南部地区高于东部地区的趋势;(3)贺州市各区县整治修复潜力差距较大,潜力最大的为八步区和昭平县,潜力提升比例最高的是富川县,不同区县可以根据结果确定整治修复的工程布局。研究结果对于区域国土空间整治与生态修复工程安排及整治修复绩效评估有重要的指导意义。Comprehensive consolidation and ecological restoration(CCER)of land space play a crucial role in guaranteeing regional ecological quality,optimizing ecological security patterns,and enhancing the ecosystem services value(ESV).Quantitative assessment of the impact of CCER on ecological quality represents a significant research challenge and focal point within the field.This study takes Hezhou City,Guangxi Zhuang Autonomous Region as a case study to measure the impact of CCER on the ESV.The main conclusions are as follows:(1)There is a big gap in per unit ESV of different quality land types.The overall level of cultivated land in Hezhou City is not high,and the per unit ESV of cultivated land is between 12,760.88 and 9,822.52 yuan/hm^(2);The overall coverage of forest land is high,and the unit ESV is between 47,828.54 and 29,062.59 yuan/hm^(2).The vegetation coverage of grassland is mostly in the middle level,and the unit ESV is between 18944.65 and 15348.36 yuan/hm^(2).The horizontal area distribution of vegetation coverage in the garden is relatively even,and the unit value is between 25,720.58 and 20,838.00 yuan/hm^(2).(2)Through CCER,the overall ESV of Hezhou City can be improved to varying degrees.The total ESV before CCER is 41.18 billion yuan,the total ESV after CCER can be increased to 45.806 billion yuan,and the total ESV can be increased to 4.626 billion yuan,with an increase rate of 11.23%.The promotion of ESV shows the characteristics that the eastern and western wings are higher than the central region and the southern region is higher than the eastern region.(3)There is a big gap in CCER potential among districts and counties in Hezhou City,with Babu District and Zhaoping County having the greatest potential,and Fuchuan county having the highest proportion of potential improvement.The main source of ESV that can be improved in all districts and counties of Hezhou City is forest ecological restoration,and Pinggui District can also come from unused land consolidation and mine restoration besides forest
