摘　　要：为研究城市化过程中洛阳市区景观生态格局的特征,在GIS技术的支持下,选取景观多样性、优势度、均匀度、破碎度和人口比重等指标对洛阳市区景观格局特征进行分析,并通过相关分析从定量角度阐明人口密度与空间格局指数之间的相关关系和相关程度。结果表明,洛阳市区各个研究区景观多样性整体程度不高、分布均匀程度较低且由某种景观占绝对优势的现象较少,绿地景观整体较好;同时相关分析中,城市化率与各个景观格局指数间相关程度较低,其中与景观多样性、均匀度、优势度、破碎度均呈现出负相关性,而只和景观破碎度表现出一定的显著性。研究结果可以看出,随着城市化进程加快,城市景观异质性降低;同时也说明人类活动对自然景观的影响虽然广泛而深刻,但是人类的行为活动并不是影响景观形成的主要因素。Supported by GIS, characteristics of ecological pattern of Luoyang in herurbanization process were analyzed with the indecies of landscape diversity, dominance, evenness, fragmentation,and population proportion. Special attention was paid to the eorelationship of landscape pattern index and population proportion. Results showed that the diversity and evenness of landscape pattern in Luoyang urban area were on a low level, none of the landscape types exhibited high dominance ,and the green land landscape was in better state. Landscape pattern indices mentioned above did not correlate with urbanization level, indication that the landscape heterogeneity decreased during the course of urbanization, and that human activity was not the main factor influencing the formation of landscape pattern.
