摘 要:根据景观生态学原理,运用CAD软件,统计各景观斑块的数量、面积、周长等信息,对广府古城滨水区的景观生态格局进行分析;并依据景观生态学的评价方法,选取分维数、伸长指数、多样性指数、优势度、分离度、破碎度6项指标对该古城滨水区进行景观生态评价。结果表明:研究区域整体多样性低、优势度高,景观分布不均匀,受人为干扰显著;自然景观锐减,景观破碎程度较高,缺乏统一有机的整体格局,导致研究区生态系统不稳定。Based on the principles of landscape ecology, apply CAD technology and data on the number, area and permieter of landscape patches in waterfront of Guangfu of the research area. Then according to the method of ancient city used to analyze the landscape pattern landscape ecological evaluation along with six indices such as fractal dimension, elongation index, landscape diversity index, dominance, separation, comprehensive landscape evaluation was performed. The results show that the low landscape fragmentation, a diversity of the whole research area, high dominance, and uneven landscape distribution must be remarkably interfered by human activities. The ecological landscape is sharply diminishing and badly fragmented, because of lacking entire pattern which resulted in the unsteady ecosystem of the research area.
