【摘要】 在总结和参考前人区划成果的基础上,通过新老区划原则的严格界定,提出了新的湖南省林业区划方案。在该方案中,湖南省被划分为5个一级区和9个二级区。在此基础上,又利用全省2004年1:1万比例尺土地利用现状图件,分析了湖南省不同区域及其林业用地的景观格局特征。结果表明,洞庭湖区域、湘中区和湘南区的景观异质性较高,这几个区域对于全省的景观格局起控制作用。湘中区和长株潭地区的景观破碎化程度最高,湘南区最低,这与区内不同的人类活动强度完全成正比。在不同亚区中,洞庭湖丘陵亚区和武陵山亚区分别对洞庭湖区域和湘西区域的多样性指数变化起控制作用;而长株潭核心区亚区、湘西武陵山亚区和湘中涟邵盆地亚区的景观的破碎化程度严重,因此,这几个区域应当是是今后区域开发过程当中应当重点加以保护和生态修复的区域。而在林业用地当中,长株潭区域和湘中区域的景观破碎化程度最高,湘西和湘南区域的破碎化程度相对较低。今后应该继续加大对湘西和湘南地区的林业保护,同时加强长株潭、湘中和洞庭湖区域的林业建设。更多还原

【Abstract】 In this paper the new project of Hunan province forestry regionalization has been brought forward by limiting strictly the principle of new and old regionalization based on summarizing and referencing regionalization result of other researchers.In this project the Hunan province has been divided into 5 region and 9 sub-regions.Based on this kind of divide,the distribution characteristics of regional landscape patterns of different region and forestry land in Hunan province were analyzed by using the land use map of 2004 which scale is 1:10000.The result showed that the heterogeneity of landscape of Dongting Lake region (DLR),Hill- basin region of Middle Part of Hunan (HBRMH) Basin-hill region of southern part of Hunan (BHRSH) were significant.The regional landscape patterns of whole province were controlled by these regions.The degree of landscape fragmentation of the HBRMH and Changsha-Zhuzhou-Xiangtan city group region (CZTCGR) was the highest.However,that of the Basin-hill region of southern part of Hunan (BHRSH) was the lowest.It was in direct proportion to the intensity of different kinds of human activity.In the different sub-region,the Dongting Lake hills subregion and Wuling mountain sub-region were each controlling the variety of diversity exponent of DLR and the West Mountain region of Hunan (WMRH) respectively.Meanwhile,the degree of landscape fragmentation of the Core sub-region of CZTCGR,Wulingshan sub-region of WMRH and the Lianyuan-Shaoyang basin sub-regoin of HBRMH is serious.Therefore,these regions should be protected and restored in ecology in the process of region exploitation in the future.The degree of fragmentation of CZTCGR and HBRMH is the highest in the forestry land use.Comparing to it,the WMRH and BHRSH were lower and it is important to give more proteetion to the forestry of these region.What’s more,it is necessary,to reinforce the construction of CZTCGR,HBRMH and DLR.更多还原
