基于土地利用空间格局的兰州市景观稳定性

doi:10.7522/j.issn.1000-694X.2014.00201

摘要/Abstract

摘要： 利用兰州市2000年和2010年两期土地利用数据,从景观结构、景观类型及景观异质性3个方面分析了研究区景观格局特征。借助主成分分析及景观格局指标对保持景观格局稳定性影响能力构建了景观格局稳定性模型,并对研究区景观格局稳定性进行了评价。结果表明:(1)近10年来兰州市景观格局发生了明显变化,主要景观类型间的转换较为频繁,且表现为明显的单向转换特征。(2)整体景观格局稳定性呈现降低趋势;各县区景观格局稳定性存在差异,榆中县永登县和皋兰县稳定性变化不大,稳定性较高的为红古区,其次是西固区、安宁区,稳定性最差的为七里河区和城关区。(3)稳定性较高的景观类型为水域及草地,稳定性较差的景观类型为建设用地。兰州市应着力提升用地潜力,提高土地集约利用程度,合理规划建设用地,保护具有生态服务功能的水域及草地等。

Abstract: This paper applied principal component analysis, combined with landscape pattern indicators affecting the ability to maintain the stability of landscape pattern, analyzed characteristic of landscape pattern from the landscape structure, features and heterogeneity, constructed evaluation model of the stability of landscape pattern, and evaluated the stability in the studied area by using land use data of Lanzhou city collected in 2000 and 2010. The results showed that landscape pattern had significant changes in Lanzhou city in recent 10 years. The conversion between the main landscape types was frequent and showed the feature of obvious unidirectional conversion. The stability of landscape pattern reduced gradually in the study area. However, the stability of landscape pattern had differences between every county, its' ranking followed Honggu District, Xigu District, Anning District, Yuzhong County, Yongdeng County, Gaolan County, Qilihe District and Chengguan District. The landscape types of the high stability are waters and grassland and the lowest is construction land. It should enhance the land potential, improve land use degree, plan construction land reasonably, and protect waters and grassland with ecological services.
