摘要: 基于延安市1990、2000、2010和2015年土地利用覆被数据,采用土地利用转移矩阵、土地利用变化速度、土地利用程度分析方法,研究1990—2015年土地利用覆被格局变化特征。结果表明,2000—2010年土地利用类型变化最明显,耕地面积明显减少,林地大幅度增加,建设用地面积明显增加,其原因是退耕还林政策的实施及城市化的发展;1990—2000年和2010—2015年,土地利用变化较小,是因为这两个阶段分别处在退耕还林实施的初期和后期;在1990—2015年整个阶段,土地利用处在调整时期,但土地利用覆被的总体格局没有发生变化。

Abstract: Based on land use and land cover data of Yan'an city in 1990, 2000, 2010 and 2015, the land-use cover change characteristic in different period was analyzed by using the methods of the land-use transition matrix, land-use change rate and land-use degree. The results showed that the land-use types had significantly changed from 2000 to 2010. The farmland area had significantly reduction, but the forestland area had increased greatly and the construction land area had increased significantly. The reason was the implementation of Grain for Green Program and the development of urbanization. In 1990—2000 and 2010—2015, the land-use change was relatively small, because these two periods were in the early and late stages of Grain for Green Program. During the whole period of 1990—2015, land use was in the time of adjustment, but the overall situation remained unchanged.

Key words: Yan'an city, land use and cover change, transition matrix, land use change
