摘要:

以湖北省咸丰县为例,借助GIS平台将分形理论应用于土地利用景观格局的特征分析,在研究典型景观格局指数的基础上,着重分析斑块形状分维数和空间结构盒维数在景观生态学中的量化表现。研究结果表明,咸丰县2007—2010年土地利用景观格局总体变化趋势为斑块面积增大、斑块个数减少、Shannon多样性和优势度几乎无变化、Shannon平均度、分离度和蔓延度加大,并对变化原因进行了分析。对斑块形状分维数和空间结构盒维数的研究分析,表明分维数可以正确地反映出景观类型的复杂性、稳定性以及人类活动干扰强度对土地利用景观格局的影响程度。

Abstract:

This paper, based on a case study on Xianfeng county, Hubei province, analyzes the land use scene pattern features by applying GIS and fractal theory. On the basis of typical scene pattern index, this paper focuses on a quantization of patch shape fractal dimension and spatial structure box dimension, shows an expanding patch area, decreasing quantity, unchanged Shannon diversity and dominance, rising Shannon average, resolution and spreading degrees in 2007—2010 land use scene pattern. Reasons are given. Patch shape fractal dimension and spatial structure box dimension show that fractal dimension can correctly reflect the complexity, stability of scene types and the intensity of human activities on scene pattern of land use impact.

Key words: fractal theory, land use, scene pattern, Xianfeng, Hubei province
