摘要
研究黄土高原地区景观格局演变对认识该地区整个生态系统结构和变化,乃至全球变化,具有至关重要的作用。本文在剖析景观格局和土地利用格局概念与内涵的基础上,从定量化分析、时空特征和尺度效应等方面对黄土高原地区景观格局演变研究进展进行了阐述,深入分析了当前研究在景观数据选择与应用、尺度依赖性分析和标准确定等方面的现状特征与不足之处,并对今后在景观格局演变方面的发展趋势进行了展望,以期为未来景观格局与过程研究提供参考。
Landscape pattern change in Loess Plateau area has an important impact on the structure and func-tion of the whole ecosystem,and even on global change.Based on the exploration of the concept and connotation of landscape pattern and land use pattern,the progress in the researches on landscape pattern change in the Loess Plateau aera is reviewed from the aspects of quantitative analysis,spatial and temporal evolution and scale effect.Although great progress has been made over the last decades,there are still many problems to be ex-plored thoroughly,such as landscape data selection and application,scale dependency analysis,establishment of assessment standards and so on.Finally,the future research trends are prospected in order to provide a scientif-ic basis for the research on landscape pattern and process.
