- 摘要:
- 植被覆盖度（FVC）对区域生态系统环境变化有着重要指示作用，利用2001年、2005年、2010年、2013年4期Landsat TM/OLI影像数据，基于像元二分模型，以黔中水利枢纽区平坝县为研究对象，得到了植被覆盖度时空变化规律，并探讨了植被覆盖度与地形起伏度、海拔、坡度和土壤类型等因子的响应关系，为县域水土保持研究提供科学理论依据。结果表明：（1）近13年平坝县植被覆盖度呈显著增加趋势，年增速为0.94%，其中2010年之前植被覆盖度呈持续增加趋势，年增速为1.72%，而2010年之后呈下降态势，年降速为-1.26%。（2）空间分布上，平坝县植被覆盖整体呈“西北高、东低”的分布特征，高值区包括齐伯乡、乐平乡和十字乡，低值区主要分布在高峰镇、马场镇和夏云镇；2001—2013年天龙镇植被覆盖度剧烈减少，马场镇和羊昌乡南部植被覆盖度剧烈增加。（3）平坝县植被覆盖度与地形因子的关系显示，植被覆盖度类型主要分布在地形起伏度 < 80 m梯度、海拔1 200～1 400 m梯度和坡度 < 25°梯度。（4）不同土壤类型的植被覆盖度变化分析结果表明：黄棕壤的平均植被覆盖度最高，为70.4%；水稻土的平均植被覆盖度最低，为42.9%；在各土壤类型区中表现为高植被覆盖度面积增加百分比最大，低植被覆盖度区域植被覆盖度面积减少百分比最大。
- Abstract:
- Fractional vegetation cover (FVC) is an important indicator of the regional ecosystem changes in the environment. We used Landsat TM remote sensing data of 2001, 2005, 2010 and 2013, took Pingba County in Qianzhong Water Control Project as the research object，and applied dimidiate pixel model to get the temporal and spatial variation of fractional vegetation cover and discuss the relationship between FVC and landform relief, elevation, slope and soil type and provide scientific basis for the research of soil and water conservation in county. The results showed that：(1) FVC of the study area exhibited a significant increase with the linear tendency of 0.94% per year in 2001—2013; during this period, a stable increase with linear tendency of 1.72% per year) was detected before 2010，followed by a sharp decline with linear tendency of -1.26% per year) after 2010; (2) spatially，FVC showed the pattern of high level in the northwest and the low level in the east. High values of FVC were mainly found in Qibo Township, Leping Township and Shizi Township. Low values of FVC were mainly found in Gaofeng Town, Machang Town and Xiayun Town. In 2001—2013, FVC in Tianlong Town decreased drastically, but increased sharply in Machang Town and Yangchang Township; (3) The relationship between FVC and topographic factors in Pingba County showed that the types of FVC mainly distributed in landform with felief of < 80 m, the elevation of 1 200~1 400 m and the slope of < 25°; (4) The analysis of the change of FVC in different soil types showed that FVC of yellow brown soil was the highest (70.4%)， FVC of paddy soil was the lowest(42.9%). In each soil type area，the area with high FVC showed the largest percentage increase while the area with low FVC had the largest percentage decrease.
