Landscape patterns indicate reduced forest fragmentation in the Danjiangkou Reservoir Area following the implementation of the Natural Forest Protection Program
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 non-NFPP 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.
期刊介绍:
Ecological engineering has been defined as the design of ecosystems for the mutual benefit of humans and nature. The journal is meant for ecologists who, because of their research interests or occupation, are involved in designing, monitoring, or restoring ecosystems, and can serve as a bridge between ecologists and engineers.
Specific topics covered in the journal include: habitat reconstruction; ecotechnology; synthetic ecology; bioengineering; restoration ecology; ecology conservation; ecosystem rehabilitation; stream and river restoration; reclamation ecology; non-renewable resource conservation. Descriptions of specific applications of ecological engineering are acceptable only when situated within context of adding novelty to current research and emphasizing ecosystem restoration. We do not accept purely descriptive reports on ecosystem structures (such as vegetation surveys), purely physical assessment of materials that can be used for ecological restoration, small-model studies carried out in the laboratory or greenhouse with artificial (waste)water or crop studies, or case studies on conventional wastewater treatment and eutrophication that do not offer an ecosystem restoration approach within the paper.
