【摘要】：湿地是位于陆生生态系统与水生生态系统之间的过渡性地带，它广泛分布于世界各地，它拥有强大的生态净化功能，对生物多样性的形成有重要的意义，是地球上一个独特的，功能繁多的生态系统，在生态系统的平衡中扮演着很重要的角色，有“地球之肾”之美誉。野鸭湖湿地自然保护区是北京的省、市级湿地自然保护区，是华北地区最大的，首都北京唯一的一个鸟类湿地自然保护区。 3S技术是GPS、RS、GIS三项技术的统称。当今社会，3S技术的集成、综合应用已经日渐深入到多个科学研究领域。3S技术应用于湿地资源的调查，湿地生态环境监测和湿地生态环境质量评价，，退化湿地生态环境恢复与重建以及保护中，是当今国内外关于湿地科学研究的前沿领域。 湿地生态环境质量评价需要反映湿地生态环境质量状况的空间格局，因此湿地生态环境质量的评价会涉及到多种、多层次的环境因素。层次分析法在多要素、多层次问题的综合评价分析方面具有独特的优势，而且3S技术在空间分析方面又有独特的强大的功能。因此，将层次分析法与3S技术相结合应用于野鸭湖湿地生态环境质量评价上，便可以充分发挥二者各自的长处与优势，这样可以很大程度上提高野鸭湖湿地生态环境质量评价的效果与水平，也可以更好的服务于退化湿地的生态环境恢复与重建工作。 本论文根据湿地生态环境质量评价的路线，评价因子与评价子因子获取的过程和一定的原则，建立了基于3S技术的野鸭湖湿地生态环境质量评价分层指标体系，研究了如何利用3S技术获取野鸭湖湿地生态环境数据的技术。利用层次分析法中的求和法对野鸭湖湿地的生态环境系统的现状进行了分析与评价，并在对野鸭湖湿地现状的了解和评价结果的分析上，对野鸭湖湿地自然生态保护区的功能分区进行了重新规划设计，并对已退化了的野鸭湖湿地的恢复和重建工作进行了设计与规划。
[Abstract]:Wetland is located in the transitional zone between terrestrial ecosystem and aquatic ecosystem. It is widely distributed all over the world. It has a strong ecological purification function and is of great significance to the formation of biodiversity. It is a unique and diverse ecosystem on the earth. It plays a very important role in the balance of the ecosystem and has the reputation of "the kidney of the earth". Wild Yahu Wetland Nature Reserve is a provincial and municipal wetland nature reserve in Beijing. It is the largest bird wetland nature reserve in North China and the only bird wetland nature reserve in the capital Beijing. 3s technology is the general name of GPS,RS,GIS three technologies. In today's society, the integration and comprehensive application of 3s technology has increasingly penetrated into many scientific research fields. 3s technology is applied to the investigation of wetland resources, wetland ecological environment monitoring and wetland ecological environment quality assessment, restoration and reconstruction of degraded wetland ecological environment and protection, which is the frontier field of wetland scientific research at home and abroad. The evaluation of wetland ecological environment quality needs to reflect the spatial pattern of wetland ecological environment quality, so the evaluation of wetland ecological environment quality will involve a variety of multi-level environmental factors. AHP has unique advantages in the comprehensive evaluation and analysis of multi-element and multi-level problems, and 3s technology has a unique and powerful function in spatial analysis. Therefore, the combination of analytic hierarchy process (AHP) and 3s technology in the evaluation of ecological environment quality of wild duck lake wetland can give full play to their respective advantages and advantages, which can greatly improve the effect and level of ecological environment quality assessment of wild duck lake wetland, and can also better serve the restoration and reconstruction of degraded wetland ecological environment. According to the route of wetland ecological environment quality evaluation, the process of obtaining evaluation factors and evaluation sub-factors, and certain principles, this paper establishes a hierarchical index system of wild duck lake wetland ecological environment quality evaluation based on 3s technology, and studies how to use 3s technology to obtain wild duck lake wetland ecological environment data. This paper analyzes and evaluates the present situation of the ecological environment system of the wild duck lake wetland by using the summation method in the analytic hierarchy process (AHP). Based on the understanding of the present situation of the wild duck lake wetland and the analysis of the evaluation results, the functional zoning of the wild duck lake wetland natural ecological reserve is replanned and designed, and the restoration and reconstruction of the degraded wild duck lake wetland are designed and planned.
