摘要
针对景观类型的关联属性,从核心层次的森林景观类型现实空间关系、高一层次的环境耦合度和干扰作用三个方面分析了森林景观类型"约束包络面"结构作用机制。景观类型的空间关系是对一定时期内景观类型相关的现状描述,隐含了景观类型中林分结构作用机制。环境耦合度反映了森林景观类型两两之间在同一环境条件下共生稳定的状态,衡量的是经营区域系统对森林景观类型格局正向的环境约束。人类干扰通过景观类型斑块动态改变景观类型,是景观类型空间关系的负向约束。在森林景观类型的"约束包络面"中,环境、景观类型与人类干扰共同筑构了高一层次的制控关系、低一层次的递进建构关系和同一层次的演化重构关系。
The mechanism and structure of constraint envelope was discussed by analyzing the relevant property of the forest landscape from real space relationship in core-level,the environment-based coupling degree and human disturbance of the forest landscape in high-level.The spatial relationships of forest landscape types describe present situation of correlation,in which the mechanism of forest stand structure was hidden.The environment-based coupling degree of forest landscape reflected the stable symbiotic state in the same environmental conditions between types of forest landscape and environmental constraints of forest landscape under the regional system.Human disturbance reflected the negative constraints by dynamically changing the landscape patch types.In constraint envelope of the forest landscape types,the environment,landscape structure combining with human disturbance built a higher relationship of control system,which consists of controlling relationships in high-level and the progressive construction relationships in the lower-level and of evolutionary remodeling relationships in the same-level.
