Investigation, Determination, and Analysis of Dominant Vegetation in Mining Areas

Abstract

During the mining process, a large amount of untreated and unusable land, namely mining wastelands, is generated. Ecological remediation in mining areas aims to rehabilitate polluted mining wasteland, thus enabling the reuse of land resources. Phytoremediation technology can effectively restore pollution in mining areas, with the prerequisite of identifying suitable tolerant or dominant plant species, which are typically found in the vicinity of mining sites with a long history of exploitation. This study conducted field surveys and collected samples, followed by laboratory analyses to explore the dominant plant species in the vanadium-titanium mining area of Zhujiabaobao, Panzhihua. Field surveys revealed a low coverage of wild vegetation due to the fragile ecological environment, primarily consisting of low, medium, and high-coverage vegetation types. Based on a comprehensive analysis of 13 dominant plant species in terms of their quantity, quality, morphological characteristics, and potential value, Eriophorum vaginatum, Rumex hastatus, and Dodonaea viscosa were identified as the three most suitable species for ecological remediation in this mining area.
