Abstract

Given that human activities have increasingly jeopardized the functionality and stability of forest ecosystems, China has implemented numerous national ecological conservation programs. Although there are many independent studies on changes in ecosystem functions or biodiversity during forest restoration processes, few have synthesized results across different restoration cases in China. Therefore, basing on 184 forest restoration studies, a review and meta-analysis was conducted to assess how ecosystem functions and biodiversity change throughout the restoration process and to evaluate their impacts. The results showed that (1) forest restoration enhanced ecosystem functions and biodiversity, with plant diversity initially declining before increasing, while microbial diversity steadily improved; (2) total phosphorus (TP) and available phosphorus (AP) were the key factors influencing biodiversity through ecosystem processes, and artificial addition of insufficient nutrient elements according to local conditions may improve biodiversity in areas undergoing forest restoration; (3) the implementation of large national ecological conservation programs was linked to biodiversity improvement observed in western China in recent years. Basing on the local restoration cases, the results can provide guides and references for the nationwide ecological conservation programs and policy decisions, which will be conducive to biodiversity protection and improvement in forest restoration process.

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.
