Study On Urban Ecosystem Diversity Optimization In Hunnan New City

Construction of ecosystem diversity is the basis for biodiversity conservation,but also to build Hunnan Metro ecosystems become the cornerstone of healthy development of the third generation of the city.The city has been the effective protection of biodiversity after the completion of the basic goals of pollution control has become increasingly important and urgent task of ecological construction.Regional diversity of ecosystems to optimize the configuration,not only to improve biological diversity and stability of ecosystems,effectively play its ecological functions,to further protect the Hunnan New City Ecological Construction and operation of the system,and urban ecosystems and other ecosystems combine interrelated to ensure that the conditions of space area of sustainable development,will promote regional ecological construction,so that the level of ecological civilization,Shenyang significantly improved,optimal allocation of diversification,particularly in Shenyang build an ecological city,ecological systems,scientific value and practical significance.Optimal allocation of regional ecosystem diversity requires consideration of the structure and functional integrity of the ecosystem,which on the one hand protect the regional ecosystem of their own development,succession;on the other hand to meet the human need for ecosystem services,ecosystem services at the same time It is also an important indicator of ecosystem health assessment.From the point of view of the scale of ecosystems,ecosystem function and human development activities will have an impact on the optimization of ecosystem diversity configuration.In this paper,by distributing surveys ecosystems Hunnan New City area cities,forests,rivers,farmland,road network and other corridors,combined with remote sensing interpretation of collected data,geographic data,and the basis of natural raw field survey,economic and social data,Hunnan New Town of ecosystem structure,composition and function of a detailed analysis of the various aspects of the system to the system of natural resources,the structure of the composition,biodiversity,and other factors were analyzed to assess the ecosystem in the region diversity,ecological diversity and stability of the level of system functionality.Hunnan New Town by the process of urbanization,the problem with the feature scope and extent of the impact on regional environmental quality,safety and other aspects of the ecosystem resulting analysis,development of Hunnan New Town ecosystem diversity optimize the allocation of evaluation methods and indicators,complete establishing the optimal allocation indicator framework for ecosystem diversity,that pressure,the corresponding index system as a framework for social and economic activities strength,strength development and construction activities,pollutant emission intensity,diversity and stability landscape spatial pattern,production,service and other functions as a secondary indicators to 24 indicators of population density as three indicators.Through the establishment of the index system framework,it is possible from the impact of human interaction with the environment and the system starting tissue classification of environmental indicators,better integration of Hunnan Metro patterns,processes,and systematic assessment of functional integration.
