为了揭示湖南三大区域内部、区域之间以及以各市州为单位的全省森林火灾损失程度差异成因及其演变特征,运用锡尔指数计算方法,从不同的空间尺度,研究了2001-2008年间湖南森林火灾损失相对差异的空间格局及其演变过程。结果表明:以市州为单位的湖南省森林火灾损失程度差异水平趋于减小;区域内部对全省森林火灾损失程度差异水平的贡献份额大于区域之间;环长株潭城市群区域内部森林火灾损失程度差异是形成全省森林火灾损失程度差异水平的主要因素,其内部各市州森林火灾损失程度差异总体有所缩小;大湘西及湘南区域内部森林火灾损失程度差异比较稳定。
In order to reveal the causes and evolution characteristics of the differences in forest fire loss in the three regions of Hunan Province, between regions and in all the cities and prefectures, using the Siier index calculation method, from different spatial scales, Spatial pattern and its evolution of relative differences in forest fire losses in Hunan Province. The results showed that: the difference of forest fire loss in Hunan Province tended to decrease with the unit of city and state; the contribution of the internal contribution to the difference level of forest fire loss in the whole province was greater than that in the region; Differences in the degree of fire damage are the main factors that have led to the different levels of forest fire losses in the whole province. The differences in the extent of forest fire losses among the cities and prefectures within the province have generally narrowed. The differences in the extent of forest fire losses in the Greater Western Hunan and Southern Hunan regions have been relatively stable.
