摘要:
基于1987年、1995年、2007年3期Landsat TM影像数据，以像元二分法估算了北洛河流域不同时期的植被覆盖度，结合DEM地形高程数据提取的地形因子，分析了植被覆盖度地形分异及动态变化特征，以期对流域生态建设和效益评价提供基础信息。结果表明：流域中9/10的面积为地形破碎的丘陵沟壑区和高塬沟壑区，2/3面积为8°~25°的斜坡地和陡坡地，各坡向面积相差不大。流域平均植被覆盖度从1987年的41.1%，1995年45.4%，增至2007年的63.4%。在各高程带、各坡度段和各坡向上，与1987年比，1995年虽有轻微增加，但其分布格局基本一致。2007年植被覆盖度在不同地形指标上均有显著增加，尤其在900~1 300 m高程带、 < 35°坡度段、阳向坡上植被改善程度显著。
Abstract:
Based on the 1987, 1995 and 2007 Landsat TM image data, combining with terrain factors extracted from DEM, trend of vegetation restoration and their distribution characteristics on the terrain were analyzed to provide basic information for watershed ecological construction and benefit evaluation in the region. Vegetation fraction was estimated using Normalized Deviation Vegetation Index derived from Remote Sensing Image and the Pixel Dichotomy Model. The results showed that ninety percent of the area in the basin was the hilly-gully and the table-gully regions; sixty-seven percent of the area was the slope with the gradients ranging from 8° to 25°; the area of the four slope aspects was almost equal. The average vegetation coverage in the basin increased from 41.1% in 1987 and 45.4% in 1995 to 63.4% in 2007 while it had a slight increase in 1995 compared with 1987 in the spectrum of slope degree, aspect, elevation, the vegetation distribution pattern was basically consistent. The vegetation coverage in 2007 increased significantly in the terrain spectrum, especially in the area with altitudes ranging from 900 m to 1 300 m, and gradient less than 35° and the sunny slope aspect.
