蒙阴县土地利用景观格局动态分析
- Title:
- Dynamic Analysis of Landuse Landscape Pattern in Mengyin County, Shandong Province
- Keywords:
- Mengyin County; landscape pattern; landscape index; landuse

- 摘要:
- 为了解蒙阴县土地利用景观格局的动态变化特征，基于1987年和2007年两个典型时期的遥感影像，运用RegionManager 5.5、Arc GIS等地理信息系统，在Fragstats 3.3软件支持下提取了部分景观指数，对研究区景观格局动态进行了分析。结果表明:（1）2007年蒙阴县的景观类型以耕地、林地、草地为主，植被覆盖率高，各景观类型间所占比例差异较小，结构较均匀。（2）1987-2007年的20 a间该区土地利用景观结构发生了明显变化，林地、城镇村及工矿交通用地面积增加，耕地等其他用地面积减少；斑块形状逐渐趋向复杂化，破碎化程度加剧。（3）由于人为活动的加剧，研究区的生态环境尤其难以维持其稳定态。因此，加大景观格局的动态监测可以进一步指导区域的土地利用规划，为其生态环境保护提供参考。
- Abstract:
- In order to understand the dynamic changes of landscape pattern characteristics, based on the 1987 and 2007 the typical period of two remote sensing images, we used the RegionManager 5.5, Arc GIS and other geographic information systems software in support of Fragstats 3.3 extracting part of the landscape index of the study area to analyze the dynamics of landscape pattern. The results showed that: (1) The main landscape types are arable land, woodland, grassland-based, with high vegetation coverage, the difference of the proportion of landscape types is smaller and the structure is more uniform in Mengyin County in 2007; (2)From 1987 to 2007 landuse structure of the landscape had changed markedly：woodland, town and village and industrial traffic area increased, as well as farmland and other land area reduced; plaque gradually complicated shape and the degree of fragmentation increased; (3)Because of human activities, the ecological environment of the study area is particularly difficult to maintain its steady-state. To increase the dynamic monitoring of landscape pattern can be further guidance to the regional landuse planning, which can provide a reference for its ecological and environmental protection.
