Group 1: Historical Context and Initiatives - Longzi County, located at an average altitude of over 3,800 meters, was once a barren salt-alkali riverbed with nearly eight months of dust storms each year [1]. - The turning point occurred in 1964 when the local leader, Langzong, learned about tree planting as a method to combat desertification during a visit to Shanxi, leading to the trial planting of seabuckthorn and other tree species [4]. Group 2: Community Involvement and Economic Impact - The community, including people of all ages, actively participated in the tree planting initiative, with seabuckthorn being the most successful due to its drought resistance and strong root system [4]. - The cultivation of seabuckthorn has significantly improved agricultural productivity, with the average yield of black barley increasing from over 300 jin to 650 jin per mu, resulting in an annual production of over 14,000 tons [4]. - The development of the seabuckthorn industry has also stimulated the local economy, leading to increased job opportunities and a projected per capita disposable income of 22,106 yuan for rural residents in 2024, reflecting a growth of 7.7% [4]. Group 3: Environmental and Social Benefits - The once sparse seabuckthorn trees have now expanded to cover 82,000 acres, creating a green barrier that has reduced wind and sand, improved arable land, and enhanced the quality of life for local residents [6]. - The establishment of ecological parks and recreational areas within the seabuckthorn forest has fostered a sense of community and environmental stewardship among the residents [6][7].
