摘　　要：以建始县国有长岭岗林场为例,选取土地类型、优势树种、海拔、坡度、坡向作为分类因子,在GIS技术支持下,建立起全场量化的、空间化的物种—环境数据库,在此基础上,采用聚类分析方法将全场划分为7个具有独立经营意义的森林景观要素类型,生成了各景观要素类型斑块图及属性数据库。各景观要素类型空间格局特征分析结果表明,全场森林景观类型具有显著的异质性,但各森林景观要素类型受干扰和破碎化程度不同,各景观要素类型空间分布状况也极不均衡,不利于森林整体质量的提升和综合效益的发挥。建议在以后的森林经营过程中,应注意结合景观尺度,对全场森林景观规划、管理、保护和恢复等经营措施进行科学设计。Taking Jianshi County Changlinggang State-owned Forest Farm for example,selecting land type,dominant tree species,elevation, slope,aspect as classification factors,with the support of GIS,a quantitative and spatial species environment database was established,on this ba-sis,seven forest landscape components types with independent management significance were determined by cluster analysis ,and the plaque map and attribute database were created.The results of analysis of landscape elements spatial pattern showed that：the overall forest landscape possess significant heterogeneity,and the disturbance and fragmentation degree of various types of forest landscape elements are different,meanwhile,the spatial distribution situation of various types are extremely imbalanced ,which is adverse to the promotion of forest quality and binging the compre-hensive benefit into full play.It was suggested that we should design overall forest landscape management measures of planning ,management,pro-tection,restoration scientifically by combining landscape scale in later forest management process .
