摘要

采用1986年和1997年夏季LANDSAT TM(30 m×30 m)遥感影像数据

对黄河中游河口镇至龙门区间主要土地利用类型

尤其是林地覆被格局的变化进行了研究。结果表明

整体上

研究区农耕地利用类型面积在减少

林灌地类型面积在增加

但是增加或减少幅度均较微弱

其变化在24条主要流域表现得不均衡。林地覆被类型与其他用地类型间相互转换的面积和形状表现得零星、破碎

变化方向不规律。林地覆被斑块数和斑块面积关系10年前后在各流域间表现得很相似

斑块数及其面积所属分级的分布格局在全区变化不大。聚类结果表明

1986年和1997年林地覆被状况在绝大多数流域间表现出巨大的相似性

全区10年前后林地覆被格局没有显著变化。
