基于生态敏感性的大汶河流域景观规划设计策略研究

Research on Landscape Planning and Design Strategy of Dawenhe River Basin Based on Ecological Sensitivity

摘要: 随着“绿水青山就是金山银山”的理念越来越受到广大民众的认可，有效地探索和实施生态问题的解决方案以及修复措施变得更加重要。为了保护大汶河流域生态，开展科学的流域生态保护，对大汶河流域开展生态敏感性评价十分重要。选取高程、坡度、地形起伏度、植被覆盖度、水体缓冲区等八个评价因子构建指标评价体系，利用GIS，自然断点法，层次分析法等方法将流域敏感性划分为五个等级，对大汶河流域生态环境进行生态敏感性评价，进一步明晰核心保护区的红线边界，有利于大汶河流域后续的景观规划设计与未来的可持续发展。

Abstract: With the increasing recognition of the concept that “green mountains and clear waters are mountains of gold and silver” by the general public, it has become more important to effectively explore and implement solutions and restoration measures for ecological problems. In order to protect the ecology of the Dawen River Basin and carry out scientific ecological protection, it is very important to conduct ecological sensitivity evaluation of the Dawen River Basin. Eight evaluation factors, including elevation, slope, terrain undulation, vegetation coverage, and water buffer zone are selected to construct an indicator evaluation system. The sensitivity of the watershed is divided into five levels using methods such as GIS, natural breakpoint method, and analytic hierarchy process. Ecological sensitivity evaluation is conducted on the ecological environment of the Dawen River Basin, providing scientific guidance and theoretical basis for subsequent ecological protection of the Dawen River Basin.
