| 摘 要： | 以遥感数据进行土地利用/覆被分类为基础,利用景观格局指数研究快速城市化地区地表覆被格局变化时,面临两大难题,即①混合像元影响分类的精度存在不确定性,直接影响格局分析结论的可靠性;②景观格局指数,难以有效分析城市内部局部地区景观格局演变过程的变化特征.针对上述关键问题,本文以不透水表面组分表征城市的主体景观,运用地统计学...

| Abstract: | Based on land cover classification data,there are two key problems that has been often overlooked when we use indices method to analyze the landscape pattern of land cover in rapid urbanization areas.One is mixed pixel involved in the classification process,which has impact on classification accuracy and the final conclusion of landscape pattern analysis.The other is that it is difficult for landscape pattern indices method to detect the change in a pixel and local urban areas,which can only explain the mac... |
