陕西：科学修复治理 让土地资源“重生”

Core Viewpoint - The ecological restoration efforts in Yulin City, particularly through the initiatives of Shenyan Coal, exemplify a successful model of balancing resource extraction with environmental sustainability, transforming mining areas into productive ecosystems [2][3][6]. Group 1: Ecological Restoration Initiatives - Shenyan Coal's West Bay mining area has undergone significant ecological restoration, turning previously barren land into a thriving environment with vegetation [1]. - Yulin City has adopted a "mining-restoration-value addition" approach, integrating ecological engineering to transform vulnerable mining areas into green oases [2]. - The implementation of a systematic ecological engineering approach has led to a recovery rate of over 95% for local vegetation, with the establishment of nearly 4,000 acres of diverse vegetation systems [3]. Group 2: Agricultural Development and Economic Impact - Yulin City has developed over 5,000 acres of high-standard farmland through agricultural demonstration projects, enhancing local agricultural productivity [3]. - Shenyan Coal has reclaimed 690 hectares of land, establishing a diversified planting system that includes grains, oilseeds, and medicinal herbs, with corn production expected to reach 506,500 kilograms in 2024, achieving a 40% increase in per-acre value [3]. - The region's agricultural practices have been enhanced through a collaborative model involving government, enterprises, and cooperatives, ensuring that local communities benefit from economic growth [3]. Group 3: Innovative Soil Management Practices - Hantai District has initiated a pilot project for the separation and reuse of topsoil, successfully reclaiming 2,200 cubic meters of high-quality soil for agricultural use, resulting in improved land quality and increased crop yields [5]. - The innovative soil management practices in Hantai District have led to a one-grade improvement in land quality and an increase of 100 kilograms in average grain yield per acre [5]. Group 4: Comprehensive Development Models - The ecological restoration efforts in Shaanxi have led to the development of two main pathways: functional optimization through restoration and resource circular value enhancement, providing a replicable model for other regions [6]. - Yulin City's approach of integrating resource development with ecological protection has created a successful model that transforms "black coal seas" into "green oases," showcasing a sustainable development strategy [6].
