摘　　要：生态环境调查与评价作为环评工作的重要组成部分,结合实际环评工作中的两个具体项目,应用植物学及群落生态学方法,比较分析人工林和次生天然林植物物种资源、不同层次的群落结构特征及其生物多样性。结果表明:与人工林相比,次生天然林的演替过程更接近天然林的演替,其物种组成相比人工林更符合自然规律,其抵御森林病虫害等生态问题的能力也优于人工林。根据研究结果,建议人工林的种植可以模拟次生天然林的演替过程,不但可以提高人工林生物多样性,而且有防患病虫害、提高人工林水源涵养等益处。Ecological environment investigation and evaluation as an important part of the EIA work,much attention should be given to the EIA projects in mining engineering,irreplaceable role of forest ecosystems in the maintenance and protection of the province's ecological environment and biodiversity.However,social and economic development to bring the mining and forest ecosystem resource protection needs gradually to highlight contradictions.In this paper,two specific items in the actual EIA,applied the methods of botany and community ecology,comparative analysis of the plantation and secondary natural forest plant species resources,different levels of community structural characteristics and biological diversity.The results show that:This explains man-made woods tend to have more plant diseases while the succession process of the secondary natural woods is more close to that of natural woods.The ability to withstand forest diseases of the secondary natural woods is better than that of man-made woods,and the makeup of species of the former is more close to natural laws than the latter.Based on the findings,the following recommendations on the plantations curing method:It is suggested that the plantation of man-made woods imitate the succession process of the secondary natural woods,in order to improve the bio-diversity,the ability to withstand forest diseases of man-made woods and the ability to conserve water source.
