摘要: 应用海南省五指山市1998年、2003年、2007年以及2012年4期TM遥感影像数据(分辨率30m×30m)和2010年海南省森林资源二类调查等数据资料,分析研究了海南省五指山市森林景观格局的时间空间动态变化特征。结果表明在1998—2007年10年内,香农多样性指数逐渐增加,五指山市景观类型更齐全,更趋于逐渐稳定平衡趋势;香农均匀度指标先增加后减小,但整体变化幅度不大,近10年内五指山市景观类型分布较为均匀,复杂度基本没变;针叶林、竹林2种景观斑块破碎度变化速度极快,斑块受到严重的破坏;经济林(乔木类)、经济林(灌木类)、非林地基本不受外界的干扰,生长状况较好;森林景观的分离度变化量较小,各斑块间相互影响较小;斑块间相互转化较少,景观类型的改变主要是因为城市建设中有较多的林地转化成了非林地。

Abstract: This paper analyzed temporal and spatial variation of forest landscape pattern of Wuzhishan city,Hainan province by using some data information including 4 TM Remote Sensing Images (resolution 30m×30m)in 1998,2003,2007,2012 and forest resource inventory & planning in 2010.The result of study indicates that within the 10 years between 1998 and 2007,SHDI has gradually increased,it means landscape types tending to more complete and stable.SHEI first increased later then decreased,and its range of variation is just among a small circle.The result indicated that landscape styles are in uniform distribution without its complexity change.The variance ratio by degree of fragmentation from landscape plaque between coniferous forest and bamboo grove are in high speed and plaque are under heavy damage.Production forest cash tree(arbor),production forest cash tree(shrub),non-forestry land grow well because of the low obstruction.The separating size to forest landscape is on the small side,there is less affection and few reciprocal transformation between plaques.Forest transformed to non-forestry land is the main change of landscape styles.

Key words: forest, landscape pattern, temporal and spatial variation
