摘要:

以大连市中心城区为研究区域,选取2003、2007、2010年的SPOT5和2012年资源02C卫星遥感影像为数据,运用遥感软件结合外业调查对遥感影像进行处理,提取中心城区绿地,在ArcGIS的支持下,结合景观生态学原理对大连市中心城绿地系统景观与生态服务价值时空分异进行研究。研究结果表明:① 大连中心城区绿地总面积逐年减少,至2012年,绿地总面积减少了2.8%,其他绿地破碎度不断提高,逐渐被附属绿地、公园绿地所代替,而绿地斑块总数由2003年的13 632个增长至2012年的14 157个,绿地斑块密度不断升高;② 绿地景观总破碎程度指数逐年增加,分布均衡性较差,公园绿地、道路与水系绿地、附属绿地生态服务价值逐渐提升,其他绿地生态服务价值不断降低,而绿地系统生态服务价值总量也从2003年的10 3162.04万元降至2012年的9 050.50万元。

Abstract:

In this article, with the downtown of Dalian City as the study area, we selected the year of 2003, 2007, 2010 and 2012’s SPOT5 and Resource One 02C satellite images as the data sources. Processing of remote sensing images with the supporting of remote sensing software, and combined with field investigation to extract the downtown area of green space, a study of spatial and temporal variation about landscape ecology service value of green space system in the downtown of Dalian was made, with the supporting of ArcGIS and combined with the principle of landscape ecology. The results show that: 1) the total area of ??green space in the downtown of Dalian decreased year by year. To 2012, the total area of ??green space decreased by 2.8%, but the fragmentation of other green space is increasing and gradually being replaced by affiliated green spaces and parks. From 2003 to 2012, the number of green space patch increased from 13632 to 14157, the density of green space patch increased; 2) the total green space landscape fragmentation index increased year by year, the distribution balance is poorer, the ecological service value of parks, roads and water green, affiliated green increase gradually, other green space decreased constantly, from 2003 to 2012, however, the ecological service value of total green space system decreased from 101.62 million yuan to 90.50 million yuan as well.

Key words: ecological services value, landscape index, green space
