摘要
为研究方正县蚂蚁河治理工程对蚂蚁河三角洲省级自然保护区生物多样性影响程度,文章从景观/生态系统、生物群落、物种/种群、主要保护对象、生物安全、社会因素6个方面产生的影响进行评价。结果表明,工程建设占地面积较小,对影响评价区内景观美学价值影响较小,不会造成该区域内生物群落分割和破碎,对野生动植物的栖息及生长环境影响不显著,不会造成生物物种的大量减少,没有外来物种及有害生物入侵的可能性,该工程完工后对当地经济发展和群众生产生活有一定的积极影响。蚂蚁河治理工程对湿地生物多样性影响指数(BI)为58.0,属中低度影响,表明工程建设对生物多样性的影响较小。
In order to study the impact of the Ant River Treatment Project in Fangzheng County on the biodiversity of the Ant River Delta Provincial Nature Reserve,the impact was evaluated from six aspects:landscape/ecosystem,biological community,species/population,main protection objects,biosafety and social factors.The results show that due to the small area occupied by the project construction,it has little impact on the aesthetic value of the landscape in the assessment area,will not cause the division and fragmentation of biological communities in this area,has no significant impact on the habitat and growth environment of wild animals and plants,and will not cause a large reduction of biological species and the possibility of invasion of alien species or pests.Moreover,the completion of the project will have a certain positive impact on the local economic development and people′s production and life.The impact index(BI)of Ant River Treatment Project on wetland biodiversity is 58.0,which belongs to medium and low impact,indicating that the project construction has little impact on the biodiversity of the assessment area.
