摘要

杨树生态撤退工程（PERP）是国际湿地保护的一项重要生态修复措施。评估湿地净初级生产力对湿地净初级生产力（NPP）的影响对于阐明人为环境影响背后的机制和评估资源利用所产生的生态效益至关重要。在洞庭湖湿地实施的PERP是一个旨在恢复湖泊湿地生境的示范性生态工程。本研究采用卡耐基-艾姆斯-斯坦福方法（Carnegie-Ames-Stanford approach， CASA）模型和遥感技术，研究了实施perp前后NPP的时空演变及其驱动因素。结果表明：(1)PERP显著改变了洞庭湖湿地覆盖的组成结构，主要是芦苇和泥滩的转换，导致白杨退缩面积大幅增加，达到13895.3 ha；(2)实施PERP后，杨树人工林内NPP显著下降，区域NPP下降63.91%。主要受芦苇滩、森林滩和苔藓沼泽NPP变化的驱动；(3)对NPP变化的驱动因子分析表明：景观格局要素（41.47%）；气候要素（30.29%）>；植被覆盖因子（8.31%）对NPP的边际效应表明，降雨量、蒸散量、斑块多样性和聚集度的增加削弱了NPP的边际效应，而温度的升高反而增强了NPP的边际效应。该研究为揭示湿地景观的人地耦合碳汇机制提供了重要参考。

Evaluation of the impact of ecological poplar retreat on the net primary productivity of Lake Wetland

The Poplar Ecological Retreat Project (PERP) serves as a crucial ecological restoration measure for international wetland conservation. Assessing the impact of PERP on the Net Primary Productivity (NPP) of wetlands is essential in elucidating the mechanisms behind anthropogenic environmental effects and evaluating the ecological benefits derived from resource utilization. The PERP implemented in Dongting Lake wetland represents an exemplary ecological project aimed at restoring lake wetland habitats. In this study, we employed the Carnegie-Ames-Stanford approach (CASA) model and remote sensing techniques to investigate the spatiotemporal evolution of NPP and its driving factors pre- and post-PERP implementation. Our findings revealed that: (1) PERP significantly altered the composition structure of wetland cover in Dongting Lake, primarily due to reed and mudflat conversions, resulting in a substantial increase in Poplar-retreat area to 13,895.3 ha; (2) Implementation of PERP led to a significant decline in NPP within poplar plantation areas, with regional NPP experiencing a decrease by 63.91 %. It was predominantly driven by shifts in NPP within reed beaches, forest beaches, and moss marshlands; (3) The analysis on driving contributions to NPP changes demonstrated that landscape pattern elements (41.47 %) > climate elements (30.29 %) > vegetation cover element (8.31 %), while marginal effects on NPP indicated that increased rainfall, evapotranspiration, patch diversity, and aggregation weakened its marginal effect whereas elevated temperature strengthened it instead. The study provided an important reference for revealing the carbon sink mechanism of the human-land coupling of wetland landscapes.

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.
