摘要:

本文提出了用于分析复杂景观异质景观要素空间关系的景观要素空间关联指数,介绍了应用GIS技术测度该指数的方法。在ARC/ IN FO支持下,对关帝山森林景观各景观要素空间关系进行了分析,从一个侧面揭示了研究地区景观格局的控制因素,掌握了研究地区森林景观要素空间分布的基本规律。研究结果表明,景观要素空间关联指数用于复杂异质景观的格局分析可取得良好效果,其生态学意义明确,实用性强。通过统一网格样方图层与景观图层叠加进行全景观取样的方法,简便、可靠、实用。关帝山森林景观受以居民点为干扰源,沿河流、道路延伸和扩展,经农田向外围渗透扩散的干扰格局和环境异质分布格局的共同控制。从复杂、破碎、高度异质的总体景观中,揭示了研究地区景观要素的空间关系,掌握了研究地区10个地类之间以及10个森林类型之间空间关系的总体格局和基本规律。

Abstract:

Supported by ARC/ INFO, using Spatial Correlation Indices of landscape structural components (SCI), this paper comprehensively analyzed the spatial relationship among landscape structural components of forest landscape in Guandishan Forest Region.The methodology of SCI measurement was explored and introduced.By integrated analysis, the key controlling affects of landscape spatial distribution pattern were explained, and general spatial distribution laws of landscape structural components were revealed in study area.The results showed that, SCI can be effectively used to analyze patterns of complex heterogeneous landscape.It generally presented explicit ecological meaning.Supported by ARC/ INFO, Unified network lan dscape sampling system was simple, convenient, reliable and practicable to measure the SCI.It was also showed that landscape pattern in study area was controlled by both environment heterogeneity and disturbance regime, which mostly come from residential area, extended along river and road corridor, and spread through farmland.From complex, fragmented and highly heterogeneous landscape, the distribution outline of all landscape structural components was revealed, and at the same time, the distribution pattern and general laws of ten forest types in study area, were also clearly explained in this paper.

Key words: Forest landscape, Landscape pattern analysis, Spatial correlation index of landscape structural components, Unified network sampling system, Guandishan Mountains
