| "Decision of the Central Committee of the Communist Party of China on Some Major Issues Concerning Comprehensively Deepening the Reform" Stressed the need to integrate ecological construction of socialism in all its aspects and the entire process in the Third Plenary Session of the 18th CPC Central Committee.According to the party's 17's "construction of ecological civilization" concept, in order to practice Scientific Outlook on Development, In the context of national support resource-based economies of certain cities, based on the trend of the "integration ofSongfu", puts forward the idea of "the construction of the integration of the double core Songfu".Through the construction of a unified and complete function of the SongFu land ecological zone, realizing the harmony between economic construction and land ecological construction.Therefore, the natural conditions and socio-economic conditions of the land use situation were investigated, relevant departments and experienced researchers were visited, relevant data and references were collected, current situation and existing problems of land use and ecological environment in the area were analysis.Firstly, current situation of land ecological function of Songfu was evaluated; and then, Ecological Function Regionalization of Songfu was determine; Finally, land ecological construction project of Songfu was established.With ARCGIS technology as the main technology platforms, remote sensing image data as the data basis, using the data spatial analysis module to establish land use and ecological function regionalization of Songfu, mainly used buffer analysis, overlay analysis, network analysis et al, combined with Fusong Administrative Division on ecological environment functional division of land use.(1) The land ecosystem function and human disturbance, potential ecological problems were adopt to classify land eco-system;The first-category classification is land ecosystem functioning.The mainly land ecosystem functions of Songfu:land ecological barrier functions, soil and water conservation functions, biological production functions, land beautification function, town greening functions.The second-level classification is classification of human disturbance intensity, mainly based on current land use indicators.Present situation of land use issignificant different in Songfu, including primeval forest which minimum disturb by human; Plantation and forest which disturb lesser by human; agricultural land, tourism land and garden land which disturb strongly by human; traffic land, industrial land and residential land which disturb maximum by human.Third-level classification is thepotential ecological problems. Main ecological problem issoil erosion in Songfu. If humanity exceeds the threshold of land use,development and utilization of land unlimited, all kinds of land will occur in varying degrees of excessive erosion.(2) Ecological zoning and functional assessment of Songfu:According to the principle of the land ecological construction, land ecological function types, ecological problems, ecological structure and level of economic select type 4 indicators were choose topartition.Land ecological structure includingtypes critical values (I), Insert bulk density (D), the average size of embedded blocks (K) three indicators, ecological environment improvement area of land spatial structure is analysisto determine the characteristics of the land ecosystem.According to the principle of ecological function zoning index of Songfu, combined with the regional features of Songfu, dividing it into four ecological function of land: Changbai mountain freezingecological area, Lava cool ecological area of Eastern Songfu, Mountain cool ecological areas ofWestenSongfu,Temperate ecological zone of Central Songfu.(3) General land ecological construction Programme:?Established integration Songfu land ecological system, Hongcang district is the core of land ecological construction, and Songfu County sub district (A sub district), and Songjinghe-Donggan town sub district (C sub district) as land core; Xinglongxiang sub district (B sub district) as land corridor; Central District as land ecological construction close-contact district; East of Central District and West District for land ecological construction as related district; East District for land ecological construction as peripheral district. ?Carry out effective management and construction programmes, making use of ecological safe, developing ecologically controlled areas moderately, rational use of ecological construction and eco-sensitive type, restrictions on the use of ecological protection, strict protection type.?Programme of eco-land whose core is ecological construction, ecological corridor construction projects, Changbai mountain Jinlongwan forest park construction project.(4)According to the different ecological function zoning of land in the area, different land ecological construction program was proposed. Main land ecological function of Changbai mountain nature reserve mountain freezingecological area is land ecological barrier function. human social economic activities is strictly prohibited, strictly prohibited hunting wild flora and fauna, do maximum effort to protect natural environment; Lava cool ecological area of Eastern Songfu, ecological protection target is achieved "natural vegetation cover", natural recovery based, supplemented by artificial restoration; Conform to nature, focus protection natural vegetation, pay attention to natural vegetation of natural stability and natural recovery of rationality and economical efficiency;Mountain cool ecological areas ofWestenSongfu, main land ecological protection target is forest land ecological system waters conservation, soil and water conservation function.According to the district natural resources and agricultural production features, adjust the proportion of agricultural, forestry, ginseng land reasonably, adapted the development of intensive, sustainable agricultural; Temperate ecological area of CentralSongfu, the three sub district of this area have different focus. Developing urban greening and landscaping work, building cities and towns "green core", the improvement and development of the Park, places of interest, tourist land greening and beautifying, based on increased within the town, and surrounding residential areas, such as land area.This research focuses on building land ecological system, select pine ecological regionalization of indicators, determining the index weight, setting up their regional strategy focuses on ecological construction, reveals the different regional land ecological environmental conditions, land use patterns, in order to determine the dominant land uses in different regions. For the rational use of land resources, and actively provide the scientific basis for ecological construction. |
