石臼湖马鞍山环湖片区景观生态规划研究

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。

RESEARCH ON THE LANDSCAPE ECO-PLANNING OF THE AREA SURROUNDING SHIJIU LAKE,MAANSHAN

Lake surrounding area is the space for intimate human-nature interactions, with rich natural resources and human resources. The landscape eco-planning of such areas can help people be harmony with nature, and coordinate the relationship between nature and resource utilization. Taking the area surrounding Shijiu lake's landscape eco-planning as an example, we analyzed the ecological environment background and ecological sensitivity. We used the relative importance index (dI) to identify the important patches, and the potential ecological corridor was simulated by Minimum Cumulative Resistance (MCR). We then overlaid the Landscape Corridors and the Recreation Corridors to the landscape ecological pattern. The landscape eco-planning for the lake area was based on the pattern, providing guidance for the area surrounding Shijiu lake, Ma'anshan. Results showed that with the guidance of the principle of Landscape Ecology, using objective and quantitative criteria for elements selection and planning can make the combination of landscape elements near or on the best structure and improve the stability of the regional landscape. It also can get the effective control on the ecological environment of the area surrounding lake.
