【摘要】：环湖片区是人与自然亲密相处的空间场所,具有丰富的自然资源和人文资源。环湖片区的景观生态规划可以协调人与自然及资源利用的关系。对石臼湖马鞍山环湖片区的生态环境基底和生态敏感性进行分析,确定重点规划区域;采用相对重要性指数(d I)识别落在规划区域内的重要斑块;运用最小耗费距离模型(MCR)模拟潜在生态廊道,并将其与景观廊道、游憩廊道相叠加;构建连续的景观生态格局,为石臼湖马鞍山环湖片区的景观生态规划提供依据和指导。结果表明,以景观生态学原理为指导,用客观定量的标准对景观要素进行选择和规划,使景观中资源组合在结构和功能上接近或达到最优化,提高区域内景观的稳定性,可以实现对环湖片区生态环境的有效保护。
[Abstract]:The area around the lake is a place where people get along with nature intimately. There are abundant natural resources and human resources. The landscape ecological planning of the surrounding lake area can coordinate the relationship between the landscape ecological planning and the nature and resource utilization. The ecological environment basement and ecological sensitivity of the Maanshan area around Shijiu Lake are divided. Analysis. Identify key planning areas; The relative importance index (RMI) was used to identify the significant patches in the planning area. The minimum cost distance model (MCRs) is used to simulate the potential ecological corridors and superimpose them with landscape corridors and recreation corridors. The construction of a continuous landscape ecological pattern provides the basis and guidance for the landscape ecological planning of Maanshan Lake area of Shijiu Lake. The results show that the principle of landscape ecology is the guide. Using the objective quantitative criteria to select and plan the landscape elements, make the combination of resources in the landscape close to or optimize in structure and function, and improve the stability of the landscape in the region. It can realize the effective protection of the ecological environment around the lake area.
