摘要：The Natural Forest Protection Program (NFPP) is the largest forest restoration program for protecting natural forests in China. The Danjiangkou Reservoir Area (DRA) offers a good opportunity to evaluate the effectiveness of the NFPP program due to its unique implementation timeline and location characteristics. While most regions initiated the NFPP in 2000, the DRA began implementation in 2011. Its proximity to both early NFPP and nonNFPP regions provides a comparative framework for assessing the program's impacts on forest landscapes. This study employed dynamic landscape patterns analysis to compare the protection effects of forest resources both within and outside the NFPP areas, as well as before and after the NFPP implementation. Among the identified landscape categories, the core class represents large forest patches with high landscape connectivity. From 2000 to 2020, the area of core forests increased by 5.01 % of the total landscape area in NFPP-I (areas that initiated the NFPP in 2000) and by 7.65 % in NFPP-II (areas that initiated the NFPP in 2011), whereas the increase was only 0.73 % in non-NFPP (areas without NFPP implementation). Meanwhile, the net growth rate of core areas in the NFPP-II rose sharply from 0.92 % of the total landscape area before the implementation of the NFPP to 13.6 % after its implementation. These findings further demonstrate the positive role of the NFPP in reducing forest fragmentation. Moreover, landscape category transitions show consistent patterns, with the islet category being prone to forest loss, whereas other categories, such as bridge, are more likely to be converted into core areas. To halt forest ecosystem degradation, we recommend implementing measures to reduce the fragmentation of plantation forests and promoting a transition to more stable landscape types. This study provides a scientific basis for comprehensively promoting the protection and restoration of forests and the sustainable development of forest resources.
