银金多金属矿对山西黑鹳保护区的影响评价

Impact Assessment of Electrum Poly-metallic Ore to Black Stork Protection Zone in Shanxi Province

文章以山西省黑鹳省级自然保护区为例,运用植物样方调查方法,通过分析银金多金属矿开采对山西黑鹳自然保护区的生态环境影响,发现该矿区主要灌木和草本植物为三裂绣线菊、黄刺玫、山蒿等,主要乔木有华北落叶松、青杨等,物种丰富度为26.700±8.819,Shannon多样性指数为0.874,反映出该地区植被稀疏、植被覆盖率较低,植被组成较简单,生态环境比较脆弱的特点。提出了应当做好确保保护区动植物安全和对地表裂缝治理、沉降预防等工作,对保护区进行绿化和覆土,逐渐恢复原本生态环境,避免采矿对自然保护区的负面影响。

Taking black stork protection zone in Shanxi province for an example, by utilizing the method of plant quadrat in-vestigation and analyzing ecological environmental impact of electrum poly-metallic mining on Shanxi black stork protection zone, the paper was found that the main mining area mainly had shrubs and herbage, such as Spiraea trilobata, Rosa xanthi-na and Artemisia brachyloba, etc. and arbor, such as Larix principis-rupprechtii and Cathay poplar; species richness was 26.700±8.819, Shannon diversity index was 0.874, which reflected the features of low rate sparse vegetation and vegetation coverage, simple vegetation composition and fragile characteristics of the ecological environment. Finally, the paper was pro-posed that shall ensure conservation of animal and plant security and governance cracks in the earth＇s surface subsidence pre-vention work, virescence and covering the sanctuary, gradually restoring original ecological environment, avoiding the negative impact of mining on protection zone.
