摘要: 林地作为森林资源的重要组成部分,是森林的基本载体,是一种重要的自然景观组分,也是城市重要的生态用地。随着城市发展,城市面积的不断向外扩展,区域范围内大量林地、湿地等被开发,导致了林地景观的空间分布的不断改变,其景观格局的变化无疑对区域生态安全格局和宏观生态环境产生了重要的影响。研究成都市生态安全格局对林地景观格局变化的响应,结果表明:成都市林地总体面积在1985年~2006年间不断减少,整个林地景观趋于破碎化,形状由复杂趋于简单。对成都市不同生态安全等级区的林地格局变化分析的结果表明:每个时期高安全区的林地的面积远大于中、低安全区且林地的破碎化程度最低;低安全区林地面积最小、斑块数目最少;林地面积和斑块数目的变化与生态安全状况的变化呈正相关;林地斑块形状的复杂程度与所在安全区域没有明显的相关性。

Abstract: As an important part of the forest resources,the woodland is the basic carrier of forests,a key component of natural landscape and principal ecological land. With urban expansion,a large number of woodlands and wetlands have been exploited for other purposes,thus resulting in constant change of spatial distribution of the woodland landscape; this change has further caused great impact on the regional ecological security pattern and macro-ecological environment. The study of ecological security pattern's response to the change of woodland landscape patterns has shown that the woodland area was declining during 1985-2006 in Chengdu city; the entire forest landscapes tended to fragmentation and its shape became simpler. The analysis of woodland pattern changes in different ecological security levels has indicated that the woodland area in high security zone during each period is much larger,but the fragmentation level is low. The woodland area in low security zone is the smallest and the number of patches is the minimum. The changes of woodland area and patch number has a positive correlation with the ecological security situation. However,the shape complexity of woodland patch has no obvious correlation with the location in security zone.
