摘要

利用1984，1986，1991，1996年和2001年的多源遥感数据，结合GIS空间数据和野外考察资料等，对1984年东营市建市17年来黄河三角洲土地利用／覆盖格局和动态演变规律进行分析。1984年以来，黄河三角洲陆地面积总体上在不断增加。土地利用／覆盖类型以旱地和未利用地为主，旱地的面积有较大的减少，而未利用地的面积变化不大，略有增加。在各个不同的时段内，土地利用／覆盖变化的面积都占1／3左右。在土地利用／覆盖变化类型中，未利用地与耕地之间的双向转换非常频繁，是最重要的两种变化类型，由于次生盐渍化的原因，耕地退化为未利用地在1986年后都占据首位；未利用地与灌草地、灌草地与耕地之间相互转化所占比例也较大。

Abstract

Based on the remote sensing data acquired in 1984

1986

1991

1996 and 2001

the land use/land cover types of the Yellow River Delta are classified. The spatial pattern and land use/land cover changes from 1984 to 2001 are analyzed. As a whole

the total area of land continuously increased from 1984 in the Yellow River Delta. The main land use/land cover types are dry land and waste land. The area of dry land decreases sharply

while the area of waste land changes little. In every period

the area of changed land is about one third. The most frequent land use change types are changes between arable land and waste land. The area from arable land to waste land is the largest from 1986. The changes between waste land and vegetation land and between vegetation land and arable land are also rapid.
