【摘要】：生态保护红线是生态保护区域的边界线,同时也是自然环境安全的底线。划定生态保护红线,不仅可以达到保护生态环境,保护自然资源的目的,同时也对实现城市的可持续发展有一定的促进作用,可以为计划部门生态建设的内容提供基础,为规划部门以及一些其它的管理部门的生态规划提供控制要求,为环境保护部门制定生态环境保护政策提供指导。本研究以辽阳市为研究区域,根据辽阳生态市规划原则和总体构想,基于生态城市的基本理念,遵循客观的生态规律和经济规律,结合区域整体发展态势、辽阳市特色和优势,以战略性的眼光、综合和动态的思维模式,以遥感和地理信息系统技术为支撑,在定性评价和定量模型相结合的基础上构建了市级尺度生态保护红线评价体系,对辽阳市的自然保护区和重要的饮用水水源地、水源涵养功能、水土保持功能、防风固沙功能、生物多样性保护功能、土地沙化敏感性,水土流失敏感性进行了评价,在这7个因子基础上,划定了辽阳市的生态保护红线。辽阳市的生态保护红线总面积为227412.5ha,占辽阳市总面积的48.07%。其中自然保护区和重要饮用水源地的生态保护红线的面积为15334.05ha,占辽阳市总面积的3.24%;水源涵养功能生态保护红线的面积为117422ha,占辽阳市总面积的24.82%;水体保持功能生态保护红线的面积为56268.75ha,占辽阳市总面积的11.89%;生物多样性保护功能的生态保护红线面积为117900ha,占辽阳市总面积的24.92%;水土流失敏感区生态保护红线面积18.75ha。从生态红线的空间分布来看,辽阳市生态保护红线主要位于东部和南部地区,这些地区的生态红线区域分布比较集中,面积较大;而西部和北部地区,生态红线面积相对较小。在生态红线区域内应采取积极的管制措施,禁止原有的生产生活以及开发活动,并结合人工恢复方式使区域内的生态系统逐步稳定,逐步恢复生态系统的自然服务功能。
[Abstract]:The red line of ecological protection is not only the boundary line of ecological protection area, but also the bottom line of natural environment security.The red line of ecological protection can not only protect the ecological environment and protect the natural resources, but also promote the sustainable development of the city, which can provide the foundation for the ecological construction of the planning department.Provide control requirements for ecological planning of planning departments and some other management departments, and provide guidance for environmental protection departments to formulate ecological environmental protection policies.This research takes Liaoyang city as the research area, according to the planning principle and overall conception of Liaoyang ecological city, based on the basic concept of ecological city, following the objective ecological law and economic law, combined with the overall development situation of the region, Liaoyang city features and advantages.Based on the strategic vision, comprehensive and dynamic thinking mode, and supported by remote sensing and GIS technology, the evaluation system of city scale ecological protection red line is constructed based on the combination of qualitative evaluation and quantitative model.The functions of water conservation, water conservation, soil and water conservation, wind and sand fixation, biodiversity protection, sensitivity of land desertification and soil erosion were evaluated in Liaoyang City.On the basis of these seven factors, the red line of ecological protection in Liaoyang city was determined.The total area of red line of ecological protection in Liaoyang city is 227412.5ha. it accounts for 48.07% of the total area of Liaoyang city.The area of ecological protection red line of nature reserve and important drinking water source is 15334.05 haa, which accounts for 3.24% of the total area of Liaoyang city; the area of ecological protection red line of water conservation function is 117422 ha, accounting for 24.82% of the total area of Liaoyang city; the water body maintains functional ecology.The area of protecting red line is 56268.75 ha. it accounts for 11.89% of the total area of Liaoyang city, the area of ecological protection red line of biodiversity conservation function is 117900ha, accounting for 24.92% of the total area of Liaoyang city, and the area of ecological protection red line of sensitive area of soil and water loss is 18.75 ha.According to the spatial distribution of ecological red lines, the red lines of ecological protection in Liaoyang City are mainly located in the eastern and southern regions, where the distribution of ecological red lines is relatively concentrated, and the area of ecological red lines is relatively small in the western and northern regions.Active control measures should be taken in the region of ecological red line, the original production, life and development activities should be prohibited, and the ecological system in the region should be gradually stabilized and the natural service function of the ecosystem should be gradually restored in combination with artificial restoration.
