Abstract: There are serious eco-environmental issues and frequent wind/sand disasters around the Beijing-Tianjin-Hebei Metropolitan Region (Jing-Jin-Ji). Jing-Jin-Ji Dust Storm Sources Control Project is an important ecological construction project in China, with the aim to minimize the sandstorm hazards around the Jing-Jin-Ji. While the project has made some progresses, there are some serious problems during the eco-restoration. The systematical analysis on the constraints to eco-environment and eco-restoration in Jing-Jin-Ji is important to the eco-reconstruction and service function enhancement. Here, we summarized the advances of researches of eco-environment in sandy land, shelterbelt status, vegetation dynamic, tree species selection, and the evaluation of ecological functions in the shelter forests in Jing-Jin-Ji, analyzed the main issues about eco-restoration, and proposed some suggestions to improve the eco-restoration, which could provide effective reference for the vegetation eco-restoration of sandy land in Jing-Jin-Ji.
