基于高分辨率卫星遥感影像的2003-2009年崂山自然保护区景观格局动态变化分析

崂山自然保护区是我国同纬度地区植物种类最多、植物区系成分最复杂的地带，也是迁徙候鸟的重要中转站和栖息地。本文基于崂山自然保护区2003年和2009年的高分辨率卫星遥感影像进行生态系统分类，开展景观格局动态变化分析。研究发现：2003年到2009年间，针阔混交林和旱地的面积呈减少趋势，而居住地、工业用地和交通用地等与人类活动关系密切的景观类型则增加；整体而言，生态系统类型并没有增加，景观内部各斑块类型面积分配比例趋向均衡，其中核心区基本保持不变，而缓冲区和实验区景观内部各斑块破碎化程度加重，趋向小块离散分布；缓冲区和实验区的农田转化为居住地、工业用地和交通用地，其中实验区变化最为剧烈，主要受人为驱动力影响，实验区长期处于无监管状态，是其剧烈变化的最主要原因。

Dynamic Change Analysis of Landscape Pattern in Laoshan Nature Reserve Based on High-resolution Satellite Images from 2003 to 2009

The Laoshan Nature Reserve is characterized by its largest volume of plant species among regions of the same latitude,and is also an important transit and habitat station for migratory birds.In this paper,we use the high-resolution satellite images from 2003 to 2009 to classify the ecological system in the Laoshan Nature Reserve,and to perform the dynamic change analysis of the landscape pattern.From 2003 to 2009,areas of the mixed conifer and dry land de-creased,while those landscapes closely related with human activities increased such as residence,industry and transpor-tation.Overall,ecosystem types did not increase,and the landscape distribution ratio of each landscape type tended to be balanced.Although the core area remained unchanged,the landscape fragmentation degree increased in the internal buffer and experimental zones.Farmland in the buffer and experimental zones was transformed to residence,industrial and transportation lands.The most dramatic changes were observed in the experimental zone,and the main driving force was human activity under no dedicated supervision.
