摘  要:
选择伊洛河流域中部洛宁县为研究区域,运用RS和GIS技术,研究1987~1996年和1996~1999年两个时段耕地时空变化。结果表明:耕地数量在1987~1996年减少,1996~1999年增加,主要为耕地和未利用土地之间的转化。1987~1999年,川涧区耕地占全部耕地比例下降,而低山区耕地比例上升;坡度小的耕地减少,而坡度大的耕地增加,研究区耕地整体质量下降。

摘  要:
By using RS and GIS technology, studies on the spatial and temporal change of cultivated land in Luoning county, middle Yiluo basin during 1987 - 1996 and 1996 - 1999 showed that the quantity of cultivated land in this area remained unchanged during 1987 - 1999, although it decreased during 1987 - 1996 and increased during 1996 - 1999, mainly due to the conversion between cultivated land and unused land. The quality of cultivated land, decreased in whole because the percentage of cultivated land of low mountain rise, the cultivated land with small, slope gradient decreased, and that with big slope gradient increased.
