摘要:
 为了解森林景观的空间组成、分布等特征对林分碳密度的影响,并以此为海口市优化林分结构,保护林地资源等方面提供参考。以海口市2015年森林资源二类调查数据为基础,运用arcgis、fragstats、spss等软件量化林分碳密度与景观格局指数并以此构建耦合协调度模型,来反映林分碳密度与森林景观格局的关系。研究发现,海口市热带林面积比重较大,且人为经营活动较强,导致其景观破碎化程度较高;林分碳密度与森林景观格局指数之间具有一定的相关性,且是相互促进的关系,当某一林分类型的空间配置较好,分布较聚集,不被其他地类分割时,其碳密度往往也较高。通过对海口市林分碳密度和森林景观格局指数的耦合研究,发现其林分碳密度与森林景观格局指数耦合协调度状况总体上并不良好,需要进行调整和改善。
Abstract:
 To understand the influences of spatial composition and distribution of forest landscape on forest carbon density,and to provide references for optimizing forest structure and protecting forest resources in Haikou.Based on the secondary forest resource inventory data for management in Haikou city in 2015,ArcGIS,FRAGSTATS,SPSS and other software were used to quantify the forest carbon density and landscape pattern index,and then a coupling coordination model was constructed to reflect the relationship between forest carbon density and forest landscape pattern.It was found that the proportion of tropical forest area in Haikou was large,and the human activities were strong,which led to the high degree of landscape fragmentation.There was a certain correlation between the forest carbon density and the forest landscape pattern index with a mutual promotion relationship.When a certain forest type had a better spatial allocation,a more concentrated distribution,and was not divided by other land types,its carbon density went to higher.Based on the study of the coupling of forest carbon density and forest landscape pattern index in Haikou city,it can be found that the coupling degree of forest carbon density and forest landscape pattern index is not good in general,which needs to be adjusted and improved.
