摘  要:
空间直观景观模型是指在异质景观中模拟景观尺度上生态过程的空间直观模型 .LANDIS是一个用于模拟森林景观干扰、演替和管理的空间直观景观模型 .通过在样地尺度上跟踪以 10年为间隔的物种年龄级 ,半定量化地描述火和风倒 ,及使用位数组表示物种年龄结构 ,LANDIS能同时在物种、样地和景观尺度上模拟各种生态过程及其相互关系 .详细论述了LANDIS模型对种子传播、火、风倒和砍伐等生态过程的模拟 ,并讨论了模型中存在的一些不足 .

摘  要:
Spatially explicit landscape models are the models that spatially explicitly simulate the ecological processes at landscape scale on heterogeneous landscape.LANDIS is a spatially explicit landscape model of forest landscape disturbance,succession and management.By recording the absence/presence of species in terms of 10-yr age cohorts at site level,the semi-quantitative description of fire and windthrow disturbances,and the representation of age-cohorts by bit-wise array,it is possible for LANDIS to simulate the ecological processes at species,site and landscape level.We addressed in detail the approaches used in simulating seed dispersal,disturbances of fire and windthrow,and harvesting.The deficiencies of the model were also discussed to provide feedback for model development.
