摘要
概述了流域景观异质性的相关概念、理论及研究,通过对国内外大量文献资料的整理,对景观异质性的成因及流域景观的组分进行了综述,提出流域景观异质性的研究重点在于嵌套流域的尺度转换。当前遥感和地理信息系统广泛应用于景观生态研究,遥感的重点在于解译分类,而现代地理信息系统所具备的空间分析功能提供了景观异质性和动态模拟研究的新途径。景观动态研究的主要途径是模型模拟,文中对以森林植被为主体对象的异质种群模型、林窗模型和空间直观景观模型进行了评述,指出景观动态模拟重点在于参数化过程中类型变量的判别根据,今后森林动态模型发展需要对空间属性和过程变化进行整合。
Relative concepts, theories and research of watershed landscape heterogeneity are summarized. The authors sum up the cause of formation of landscape heterogeneity and the composition of watershed landscape, and put forward the key of researching on watershed landscape heterogeneity is scaling of nested watershed. Nowadays, remote sensing （RS） and geographic information system （GIS） are applied widely on landscape studying. An important step of RS application is interpretation and classification, and moreover, the spatial analyses of modem GIS provides a new way of landscape heterogeneity and dynamic simulation study. Main means of dynamic landscape researching is modeling. The authors review heterogeneous population model, forest gap model and spatial explicit landscape model that aimed at forest and plant succession and disturbance. In the process of model parametrizing, reasonable types of variables must to be made certain. In the future, the development of forest dynamic model demands spatial attribute and change process to be combined and conformed.
