江汉平原土地利用变化分析

Study on Land-using Change in Jianghan Plain

以江汉平原20世纪809、0年代和2000年3个时期内的土地利用类型动态监测结果为基础,对其进行了利用状况分析、土地利用程度分析、利用程度变化分析和土地利用变化的区域差异分析。结果表明:该区域耕地面积在不断减少,围湖造田的现象依然存在;土地利用程度相对较稳定,属于农业用地类型;土地利用格局尚未完全定型,处于调整期;土地利用变化的区域性差异不明显。

Based on the remote sensing monitored LUCC data at three different periods of 1980s,1990s and 2000 in Jianghan plain,The status and degree of land-using,and its change and difference of land-using of Jianghan plain were analyzed.The result showed that the cultivated land area was decreasing,and the reclaiming land from the lake was still being;the degree of land-using was correspondingly steady,belonging to agricultural land type;the pattern of land-using was not formed,being in the adjusting Period.And there was regional .difference in land-using but it was not very significant.
