The Research Of The Hebei Key Ecological Function Reserve Area

The key ecological function reserve area refers is the use of modern theory and method of ecosystem with important ecological functions to conserve water, soil and water conservation, flood storage, sand-fixing, maintenance of biolofical diversity has important ecological function of important areas, selected to be designated a certain area of protection and limitationd development and construction of the area.The research of the key ecological function reserve area is to ensure the main stable and sustaining, flooding and micro-climate regulation. The purpose of this thesis was to propose the divison planning and conservation strategies of Hebei key ecolofical function reserve areas based on the analysis of the ecological environmental status in Hebei province, to develop sustainlly both ecological security and economy.In the study, identify the status of environmental quality in Hebei Province by interpretation of remote sensing and GIS technology, the reference number of related research and solicit expert opinion, for the sources of rivers, flood control, water conservation, drinking water sources protection, soil and water conservation, wind sand, biodiversity, wetlands, coastal zones in Hebei Province and so on, building include run off, water conservation capacity, soil and water conservation capacity, biodiversity and other indicators of reasonable system, the quantitative indicators, to determine the weight, the establishment of a multi-source data analysis and evaluation of the coupling model and using analytic hierarchy process, taking Data and gray cluster analysis and other analysis comprehensive evaluation and analysis, the use of Arcview, Erdas, ArcGIS and other geographic means to support information systems to analyze the various elements of regional ecosystems in the number, type, structure and spatial location of information, and ultimately selected 17 important ecological function protected areas.According to different type of important ecological function reserves every important ecological function, and puts forward the corresponding countermeasures and protection area in HeBei Province as the future direction of development, the key of ecological environment protection. And established the HeBei Province important ecological function reserve geographic information system, for how to better management and protection of ecological environment HeBei Province provides decision-making basis.The study put forward in HeBei Province as an example for important eco function reserve protection measures and methods to determine, imformtion management system, carry out for other provinces for important eco function reserve study provides reference.
