| 摘 要： | 利用Landsat和MODIS遥感数据和InVEST模型，评估了1990―2015年大兴安岭天保工程区实施前后生态系统土壤风蚀量、生境质量和碳储量的时空变化，并通过地理探测器方法对生态系统服务时空变化分布与趋势进行驱动因子探测和交互作用探测分析。结果表明：① 从空间分布来看，额尔古纳市南部、鄂温克族自治旗西北部、科尔沁右翼前旗的土壤风蚀量大，生境质量差，碳储量低。② 2000年天保工程实施之后，森林面积显著增加，土壤风蚀量减少1.14%，生境质量增加0.49%，碳储量减少幅度为0.12%，低于2000年以前的0.64%。③ 土壤风蚀量主要受植被类型、土壤类型的影响，生态系统类型、植被类型对生境质量、碳储量空间异质性的影响显著大于其他因素，海拔、坡度2种地形因子对土壤风蚀量、碳储量的解释能力很小。温度、降水2种气候因子对土壤风蚀量、生境质量和碳储量的解释能力不固定，但仍是不可或缺的因素。 |

| Abstract: | The Da Hinggan Mountains is the key area of Natural Forest Protection Project Regions (NFPPR) of China. It is great significance to scientifically and systematically evaluate the ecosystem changes of the project and analyze the reasons of the changes, so as to monitor and improve its effect. In this study, Landsat and MODIS remote sensing data sources and InVEST model were used to evaluate the temporal-spatial evolution trend of soil wind erosion, habitat quality and carbon storage of the ecosystem the implementation of Natural Forest Protection Project (NFPP) in the Da Hinggan Mountains from 1990 to 2015, and the driving factors and interactions of the temporal-spatial change distribution and trend of ecosystem service function were detected and analyzed by geographic detector method. The results showed that: 1) From the perspective of spatial distribution, the amount of soil wind erosion in the south of Erguna City, the northwest of Ewenki Autonomous County and Horqin Right Front County was large, the habitat quality was poor, and the carbon storage was low. 2) After the implementation of NFPP in 2000, the area of forest increased significantly, soil wind erosion decreased by 1.14%, habitat quality increased by 0.49%, and carbon storage decreased by 0.12%, lower than 0.64% before 2000. 3) Soil wind erosion is mainly affected by vegetation type and soil type. The impact of ecosystem type and vegetation type on habitat quality and carbon storage is significantly greater than other factors. Altitude and slope have little explanatory power on soil wind erosion and carbon storage. Temperature and precipitation are not fixed in explaining soil wind erosion, habitat quality and carbon storage, but they are still indispensable factors. The results of this study can provide important data support and scientific basis for regional ecological restoration and protection and ecological civilization construction. |
