Effect of grazing exclusion on ecosystem services dynamics, trade-offs and synergies in Northern Tibet
The relationships between different ecosystem services are key to regional ecological stability and security, and their trade-offs and synergies are affected by many factors, especially on the Qinghai-Tibet Plateau (QTP), which is susceptible to human activities. Norther Tibet, located on the QTP, has built fences for grazing exclusion in recent years. However, how grazing exclusion affect the ecosystem service variability and their mechanism remains still unclear. Based on the net primary productivity (NPP) quantitative index method, hotspot analysis, geographically weighted regression (GWR) model, this study analyzed the effects of grazing exclusion with fencing on ecosystem services dynamics, trade-offs and synergies. Results showed that the values of biodiversity conservation, water conservation and soil conservation were all higher in the fencing region than in the non-fencing region. Most counties experienced increasing trends in the fencing region with higher biodiversity conservation, water conservation in the fencing region than that in the non-fencing region from 2006 to 2015. Except for the relationship between soil conservation and water conservation in the non-fencing region in Cuoqin county in 2015, the relationships among all ecosystem services were synergistic, and the overall trends were weakening. The county number percentage with higher synergistic relationships in the fencing region than that in the non-fencing region showed gradually increasing trends. Land use intensity, grazing intensity, precipitation and altitude were the main factors that affecting spatial heterogeneity of three ecosystem services in the non-fencing region, while distance to road, distance to town, land use intensity and temperature were the main influencing factors in the fencing region. This study contributes to exploring the effect of grazing exclusion on ecosystem services and their relationships, thus providing guidance for the formulation of grassland restoration measures
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.
