【摘要】：近年来,随着社会经济的快速发展,城镇化进程加快,导致经济发展与生态保护的人地矛盾日益尖锐。我国生态系统的服务功能开始下降,生态恶化的范围不断扩大,所引发的生态问题日益加剧。鄂尔多斯能源开发区土地开发利用活动频繁、剧烈,加之自身生态环境比较敏感,因此生态问题突出,对鄂尔多斯能源开发区的生态安全构成威胁。如何将有限的土地进行合理的分配,处理好开发与保护、人类与生态的关系,走可持续发展之路,已经成为当前人类社会所面临的严峻挑战。生态红线是我国近几年提出的一个全新的生态保护管理手段,通过划定生态红线,合理协调分配生产、生活和生态的土地利用空间分布,从而维护区域生态安全,实现生态与经济可持续发展。生态红线的划定需要综合考虑自然环境、社会经济、生态状况等诸多因素。本研究以生态红线的提出为出发点,并结合国内外关于生态红线的研究进展,研究分析生态红线的内涵和理论基础,确定生态红线的划定方法。选取鄂尔多斯能源开发区为研究区,在分析研究区自然条件和社会经济条件、土地利用现状和变化、生态环境问题的基础上,进行生态红线划定。根据区域生态环境敏感性评价和生态价值重要性评价结果,并综合土地利用功能分区和土地规划功能分区的生态功能分值,通过空间叠加分析,将鄂尔多斯能源开发区划分为生态红线区、黄线区和绿线区,初步确定各分区的面积范围和空间分布,并根据区域分区的不同特点,分别提出各分区的不同管理保护措施。生态红线划定结果基本符合鄂尔多斯能源开发区的实际情况,说明该生态红线划定方法科学合理可行。鄂尔多斯能源开发区的生态红线区面积为784361.61公顷,占全市总面积的9.03%,黄线区面积为3653036.41公顷,占全市总面积的42.03%,绿线区面积为4253404.61公顷,占全市总面积的48.94%。红线区应该以生态保护为主,严格禁止一切有损于生态系统的开发活动;黄线区必须严格控制该区域的开发强度,在不削弱区域生态功能的基础上适度开发,并加强对生态环境的恢复和重建,要注意经济建设和生态保护之间的协调关系;绿线区可以引导性开发,适宜进行适度规模的开发建设活动,但仍需要合理确定发展方向和管制规则,对开发、建设等利用方向要有一定的限制要求,否则有可能也会出现相应的生态问题。
[Abstract]:In recent years, with the rapid development of social economy and the acceleration of urbanization, the contradiction between economic development and ecological protection has become increasingly acute.The ecosystem service function of our country begins to decline, the scope of ecological deterioration is expanding, and the ecological problems are becoming more and more serious.The development and utilization of land in Ordos Energy Development Zone is frequent, intense, and its own ecological environment is relatively sensitive, so ecological problems are prominent, which pose a threat to the ecological security of Erdos Energy Development Zone.How to allocate the limited land reasonably, deal with the development and protection, the relationship between human and ecology, and take the road of sustainable development, has become a severe challenge to human society.Eco-red line is a new ecological protection and management method put forward in recent years in our country. By delimiting ecological red line, rationally distributing production, living and ecological land use spatial distribution, thus maintaining regional ecological security.To realize the sustainable development of ecology and economy.The demarcation of ecological red line needs to consider many factors such as natural environment, social economy, ecological condition and so on.In this study, the ecological red line was put forward as the starting point, and combined with the research progress of ecological red line at home and abroad, the connotation and theoretical basis of ecological red line were studied and analyzed, and the delineation method of ecological red line was determined.Based on the analysis of the natural and social economic conditions, the present situation and changes of land use, and the ecological environmental problems, the ecological red line is determined in Ordos Energy Development Zone.According to the results of regional ecological environment sensitivity assessment and ecological value importance evaluation, and synthesizing the ecological function scores of land use function partition and land planning function partition, the paper analyzes the ecological function by space superposition analysis.The energy development zone of Ordos is divided into three areas: ecological red line, yellow line and green line. The area range and spatial distribution of each zone are preliminarily determined. According to the different characteristics of the regional zone, different management and protection measures are put forward respectively.The result of ecological red line delineation basically accords with the actual situation of Erdos Energy Development Zone, which shows that the method of ecological red line delineation is scientific, reasonable and feasible.The ecological red line area of Ordos Energy Development Zone is 784361.61 hectares, accounting for 9.03 of the total area of the whole city, 3653036.41 hectares of yellow line area, 42.03 of the total area of the whole city, and 4253404.61 hectares of green line area, accounting for 48.94 hectares of the total area of the whole city.The Red Line region should focus on ecological protection and strictly prohibit all development activities harmful to the ecosystem. The Yellow Line region must strictly control the development intensity of the region, and develop moderately on the basis of not weakening the ecological function of the region.And to strengthen the restoration and reconstruction of ecological environment, we should pay attention to the harmonious relationship between economic construction and ecological protection.However, it is still necessary to determine the development direction and control rules reasonably, and to restrict the utilization direction of development and construction to some extent, otherwise, the corresponding ecological problems may also appear.
