Abstract: As an important natural forest distribution area in China, Northeast China is a significant implementation area of the Natural Forest Protection Project (NFPP). The improvement of project implementation effects and regional ecological protection requires a systematic evaluation of ecosystem changes before and after the implementation of the NFPP. To achieve this aim, this study compared the changes in landscape pattern, ecosystem quality and services from 1990 to 2000 and from 2000 to 2015 by means of Landsat and MODIS data and InVEST model. Results show that 1) forest area increased by 2 133 km2 from 2000 to 2015; 2) ecosystem quality was improved after the implementation of the NFPP characterized by increasing LAI and NPP; 3) forest ecosystem carbon stocks increased by 49 Tg and habitat area in poor suitable grade decreased by 1 423 km2, while water yield of forests decreased by 3.5×109 m3. Although NFPP has achieved obvious ecological effects, there were tradeoffs between water yield and other ecosystem services such as habitat quality and ecosystem carbon sequestrations. Given the findings in this study, we argue that regional ecosystem protection needs to be further improved, and this study will be expected to provide data support and scientific basis for rational use of regional natural resources and the construction of ecological civilization.
