山东半岛县域土地利用景观格局分析——以招远市为例
- Title:
- Analysis of Landscape Structure of Land Use at County Scale in Shandong Peninsula——A Case Study of Zhaoyuan City
- Keywords:
- Zhaoyuan city; landscape structure; land use; GIS
- 分类号:
- F301.24
- 摘要:
- 在GIS技术支持下，利用ERDAS软件对2004年招远市遥感图像进行处理，在Arc/info平台下进行解译，再结合招远市土地利用现状图，得到招远市景观格局数据.然后在土地分类的基础上结合景观生态学原理对招远市景观进行分类.根据研究区的实际情况选取斑块水平指数和景观水平指数两类指标对招远市景观格局进行分析.利用景观格局分析软件FRAGSTATS.对所选指标进行量化分析.分析得出：招远市景观类型比较丰富，有着典型的"斑块-廊道-基质量"特征，耕地景观占绝对优势.斑块形状受地貌影响显著，集中体现在草地上，其形状指数大于其他景观类型.气候因素对斑块优势度影响较大.人类活动对景观空间结构有着强烈影响，人类活动的加剧会使景观破碎化程度加深.
- Abstract:
- Supporting by GIS,the image in 2004 of Zhaoyuan was disposed by ERDAS.Using the Arc/info to interpret and assisting the present map of the land utilization,obtain the date of landscape structure.Basing on the land classification and the landscape ecology principle,and according to actual condition of the study area,the patch level indices and the landscape level indices were selected to analyze the landscape structure of Zhaoyuan.Then carry on the quantification analysis to the selected indices by FRAGSTATS3.3.The results show that Zhaoyuan has the ample classes of the landscape,and it accords with the model of "patch-corridor-matrix";The plantation dominate the landscape of Zhaoyuan;yet the patch shape is mainly affected by landforms,being reflected by the class of grass with shape index bigger than other landscape types; the climatic factor can also affect the patch dominance;the landscape structure has been affected obviouslv by human activities,with increase of human activities index increased greatly.
