Public views of ecological security barrier projects contributions towards sustainable development goals in Tibet plateau

Tibet Plateau plays an important role in protecting the ecological security of China and even Asia, to ensure its normal and effective ecosystem function, a series of ecological security barrier protection and construction projects have been implemented. The sustainable development goals(SDGs) of the United Nations can provide a broad framework for optimizing and coordinating the ecological security barrier protection and construction projects. The public to the understanding of ecological security barrier projects and sustainable development goals can influence their decision making and participation. We determine public understanding of the projects through its contribution to SDGs. Using the results of department questionnaire in Linzhi City (n=176), we identified nine projects contribution to sustainable development goals and different cognitive patterns for them. Soil and water loss control project and sand control project have more contributions to SDSs , while the contributions of returning grazing to grassland and pest control project and traditional energy substitution project in agricultural and pastoral areas to SDGs are relatively small. Soil and water loss control project is to realize the basic requirements and management goals largest contributor, sand control project is the largest contributor to achieving the expected goals. From the cognitive patterns we see individual differences in participants, but the dominant cognitive patterns among individuals are identified. We put forwards suggestions for optimizing ecological security barrier projects to promote the achievement of the United Nations Sustainable development goals.
