    摘要:

    通过对影响曹妃甸新区景观生态安全的水文、地质灾害和海岸防护、生物多样性保护、文化遗产和游憩4种景观过程进行分析和模拟,运用最小累积阻力面模型和加权叠加方法,分别构建了单一因素的高中低 3 种水平的景观安全格局,进而采用析取运算(V)进行叠加,形成了曹妃甸新区 3 种安全水平的综合安全格局。结果显示,曹妃甸新区低、中、高 3 个不同安全水平的生态安全格局用地分别占研究区总面积的14.15%、42.19%、25.02%。其中低水平安全格局为城市发展提供最基本的生态系统服务,是城市发展底线,须严格保护。研究可为曹妃甸新区国际生态城建设提供参考,同时对促进中国东部沿海城市可持续发展也具有一定的参考意义。

    Abstract:

    In this study, through the analysis and simulation of landscape process which influence the landscape ecological security of Caofeidian new area: hydrological, geological hazards and coastal protection, protection of biodiversity, cultural heritage and recreation, the minimum cumulative resistance model and weighted superposition method were used, and the landscape security pattern of single factor in high, medium and low level was constructed, then the extraction operation (V) was superimposed, in the end a comprehensive security pattern of Caofeidian new area in three security levels was formed. The results showed that the different security levels, low to high, of the ecological security pattern of land accounted for the total area of 14.15%, 42.19% and 25.02% in Caofeidian new area. The low level security pattern provided the most basic services for ecological system for the city development, which was the bottom line of city development and must be strictly protected. This study can provide a reference not only for Caofeidian international eco-city construction, but also for the sustainable development of China’s eastern coastal city.
