As a major area of resource consumption and carbon emissions, cities face the challenge of achieving green and sustainable development. This study analyzes the impact of low-carbon pilot policies on urban land green utilization, exploring their role in promoting the greening of urban land resources, reducing carbon emissions, and fostering sustainable development. Using a combination of quantitative and qualitative methods, and drawing on multiple case studies from typical cities, the study reveals the mechanisms through which low-carbon policies affect urban land use. The results show that low-carbon pilot policies significantly promote urban land green utilization, particularly in land development planning, land use efficiency, and ecological protection. This study provides theoretical support for further optimizing low-carbon policies and offers references for other cities' green development.</p> Zhang Xin ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 2025-04-16 2025-04-16 6 1 p1 p1 10.30560/ls.v6n1p1 https://j.ideasspread.org/index.php/ls/article/view/1580 <p class="text">Haidong City is located in the eastern region of the Tibetan Plateau and the upper reaches of the Yellow River, which is an important agricultural area in Qinghai Province. Surface soil erosion in this area not only reduces soil quality, but also leads to the pollution of the Yellow River water and the increase of sand transport.The soil erosion status of Haidong City in 2022 was assessed using the modified soil loss equation (RUSLE model), combined with landsat8 OLI imagery, DEM, rainfall and land use data, and RS and GIS techniques. The results show that soil erosion in Haidong City is dominated by slight and mild erosion, with an area of 7,835 km² and 2,735 km² respectively.Among the districts (counties), Ledu District and Mutual aid County have the largest area of strong erosion, with an area of 633 km² and 144 km² respectively; Ping'an District and Minhe County have a smaller area of strong erosion, with an area of 11 km² and 30 km² respectively.Between the different land-use types. grassland erosion area was the largest, with an area of 7449km², accounting for 59.83%. The results of the above study can provide a scientific basis for soil degradation management in the region to meet the challenges of fragile ecological environment and increasing land use.</p> Qi Jigui Jia Wei Xie Huichun Ma Yujun ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 2025-05-08 2025-05-08 6 1 p11 p11 10.30560/ls.v6n1p11
