【摘要】 本论文对矿业开发密集地区生态退化情况进行了综合评价,为该类地区的生态恢复与重建提供了理论依据,使退化的生态系统得到了最佳的恢复与发展。对于改善矿业开发密集地区的生态环境具有重要的理论意义和现实指导意义。本论文主要在以下几个方面进行了探讨,包括矿业开发密集地区生态退化的特点;生态退化综合评价指标体系的选择及评价方法的研究;矿业开发密集地区生态退化地理信息系统的研制与开发;针对研究区域退化特点提出了防治对策。(1).矿业开发密集地区生态退化的特点是:驱动系统退化干扰力远远大于自身的抵抗力;退化的时间短、速度快,退化程度极为严重;系统恢复能力弱,自然恢复速度慢。(2).论文首次提出了考虑均衡度的灰色关联分析法,并建立了综合评价的指标体系,对迁安各乡镇由于矿业开发所造成的生态退化进行了综合评价。(3).在调查研究的基础上,以MapInfo为平台,通过把图形数据和属性进行有机结合,初步建立了矿业开发密集地区生态退化地理信息系统。从而实现了数据的输入、管理、分析及输出,为进行综合评价和系统分析提供支持和服务。(4).在调查研究及综合评价的基础上,针对研究区域内生态退化的现状,从技术的角度出发,提出了有针对性的对策及措施。更多还原

【Abstract】 A all-round assessment was made for the ecosystem degradation in intensive district of mining, and this make a theory foundation for recovery and restoration of ecosystem of mining district, in addition, it make the degraded ecosystem develop fully and recover.. The paper is theory and practical significance for improving the environment of dense mining districts.The paper mainly discuss several aspects: character of ecosystem degradation of dense mining districts, choice synthetically index of estimation and research on method of estimation, research and develop geographic information system about dense mining districts, according to character of ecosystem degradation of dense mining the paper brings forward measures for them.(1).The characteristic of ecosystem degraded in dense mining district. The interfering power is much harder than the resistance of ecosystem; the degradation of ecosystem is rapid and grievous; the restoration power is weakly and the speed of restoration is very slow.(2).This paper put forward the gray theory concerning balance and formed the indexes system for synthetic assessment. The assessment was made for the ecosystem degradation in intensive district of mining in Qian’an.(3).The figure dates and property dates were connected in order to show the factors about ecosystem degenerated. The MapInfo is used and the dates collected are saved, managed, operated, analyzed and showed. And this can offer support and service for synthetic assessment.(4).On the base of research and synthetic assessment the paper put forward the measure for the ecosystem degradation.更多还原
