Core Points - The article discusses the efforts in Gansu's Sunan County to "lock the edges" of the Badain Jaran Desert, focusing on environmental protection and land management initiatives [1][2][3][5][6]. Group 1: Environmental Initiatives - The "locking edges" project aims to combat desertification and protect the surrounding ecosystems [1][2]. - Local authorities are implementing measures to stabilize sand dunes and improve vegetation cover in the region [3][5]. Group 2: Economic and Social Impact - The project is expected to enhance local livelihoods by promoting sustainable land use practices [6]. - Increased environmental stability may lead to better agricultural productivity and tourism opportunities in the area [1][2].

Group 1 - The core viewpoint of the articles is the completion of a significant ecological project in the Tengger Desert, which involves a 153-kilometer "green chain" to combat desert expansion and protect the Yellow River [1][2] - The project is part of a broader initiative to manage desertification in China, emphasizing the importance of not eliminating deserts but rather managing their expansion [2][3] - The Ningxia region has successfully retreated the Tengger Desert by 25 kilometers over the past decades through various ecological projects, including the "Three-North" program [2][3] Group 2 - The locking technique involves using grass grids to stabilize shifting sands, which has proven effective in preventing desert encroachment [3][4] - Innovative technologies are being employed, such as a specialized planting tool that increases the survival rate of saplings in sandy conditions from 60% to over 80% [4] - Future plans include enhancing cooperation with Inner Mongolia for joint ecological management and developing sustainable industries like desert tourism and solar energy [5][6]
