The Evaluation And Research Of Bole City's Ecological Security

On the basis of the research into Ecological Security development status at home and abroad, make use of PSR Frame Model, establish Destination Layer, Items Layer and Indicator Layer three class Urban Ecological Security Evaluation Indicator System which combined with Bole City's natural, social and economic conditions status quo. Simultaneity, make reference to EcoCity Construction Standard promulgate by State Environmental Protection Administration, state environmental quality standards, such as Ambient Air Quality Standards(GB3095-1996), Environmental Quality Standard for Surface Water(GB3838-88), Urban Ambient Noise Standards, and so on. Together with the particularity of urban ecosystem, distributed Bole City Ecological Security Evaluation Standard into five classes: very unsafe, restricted safety, criticality safety, safer, ideal safety. Empowerment by way of mean square deviation decision-making method. Analyzed the Bole City Ecological Security indicator data 2002-2006 by Grey Relational Evaluation and Fuzzy Comprehensive Evaluation. finally, come to a conclusion as follows:Grey Relational Evaluation: Bole City's max degree of association on 2002,2004,2005 comes under class "criticality safety", same as Bole City's Urban Ecological Security comes under class "criticality safety"; Bole City's max degree of association on 2003,2006,comes under class "safer", same as Bole City's Urban Ecological Security comes under class "criticality safety".Fuzzy Comprehensive Evaluation: Bole City's Eigenvalue-level on 2002,2003 approach to 3, same as Bole City's Urban Ecological Security comes under class "criticality safety"; Bole City's Eigenvalue-level on 2004-2006 approach to 2, same as Bole City's Urban Ecological Security comes under class "safer".Bring forward some countermeasure by integrated analyze and compare two outcome assessment mentioned above, such as strengthen urban ecological security programming, protected the environment and natural resources, Constantly publicized and promote hoi polloi practice economy, control pollution sources, prevent eco catastropie by afforestation, improve the legal system about preserve the ecological environment proceeded, entire push urban society-economy-environment on Sustainable Developent, to improve Bole City's ecological security level.
