- 摘要:
- 植被是陆地生态系统的重要构成,研究植被变化规律及影响因素有助于加强区域植被生态保护和可持续发展。基于SPOT NDVI和气象数据,采用趋势分析、偏相关分析和残差分析等方法对2000—2019年黄河流域陕西段植被NDVI时空变化特征及其驱动因素进行了分析。结果表明:(1)2000—2019年黄河流域陕西段植被NDVI总体以0.008 6/a的速率呈极显著增加趋势,不同地域NDVI增速为陕北(0.010 9/a)>关中(0.005 3/a),不同土地利用类型NDVI增速为草地(0.011/a)>耕地(0.008 1/a)>林地(0.007 8/a)。(2)植被NDVI呈增加趋势的面积占比为86.19%,其中显著增加的面积比例为81.90%,陕北(91.87%)>关中(66.91%),林地(97.48%)>草地(90.38%)>耕地(69.78%)。(3)偏相关分析发现90.24%的区域植被NDVI与年降水量以正相关关系为主,66.3%的区域植被NDVI与年均温呈正相关关系。(4)研究区植被NDVI变化受到气候变化、人类活动以及二者共同作用的影响,占比分别为5.65%,73.11%,21.24%,人类活动面积占比陕北(79.88%)>关中(55.49%),草地(85.2%)>耕地(73%)>林地(59.67%)。总体上,2000—2019年黄河流域陕西段植被活动明显增强,降水相比温度对研究区植被影响更大,人类活动是研究区植被变化的主要驱动力,这为研究区生态建设和植被恢复提供了重要参考。
- Abstract:
- Vegetation is an important component of the terrestrial ecosystem, and studying the rules of vegetation change and its driving factors is helpful to strengthen the ecological protection and sustainable development of regional vegetation. Based on the SPOT NDVI and meteorological data, spatiotemporal characteristics of vegetation NDVI change and its driving factors in the Shaanxi section of the Yellow River Basin from 2000 to 2019 were analyzed by trend analysis, partial correlation analysis and residual analysis. The results are as follows.(1)from 2000 to 2019, the vegetation NDVI in the Shaanxi section of the Yellow River Basin showed the significant increase trend at a rate of 0.008 6/a; the NDVI growth rates in different regions decreased in the order: northern Shaanxi(0.010 9/a)>Guanzhong(0.005 3/a), and the NDVI growth rates in different land use types decreased in the order: grassland(0.011/a)>cropland(0.008 1/a)>forest(0.007 8/a);(2)the proportion of area with an increasing trend of vegetation NDVI accounted for 86.19%, of which the proportion of area with a significant increase was 81.90%; the proportion of area with the increased NDVI in different regions decreased in the order: northern Shaanxi(91.87%)>Guanzhong(66.91%), and the proportion of area with the increased NDVI in different land use types decreased in the order: forest(97.48%)>grassland(90.38%)>cropland(69.78%);(3)90.24% of the regional vegetation NDVI was positively correlated with annual precipitation, and 66.3% of the regional vegetation NDVI was positively correlated with the annual mean temperature;(4)the changes of vegetation NDVI in the study area were affected by climate change, human activities and their combined effects, accounting for 5.65%, 73.11% and 21.24%, respectively; among them, the proportion of human activity area decreased in the order: northern Shaanxi(79.88%)>Guanzhong(55.49%), grassland(85.2%)>cropland(73%)>forest(59.67%). Overall, the vegetation activity in the Shaanxi section of the Yellow River Basin was significantly enhanced from 2000 to 2019. Precipitation had a greater impact on vegetation than temperature in the study area. Human activity was the main driving forces for vegetation change in the study area. These conclusions can provide an important reference for ecological construction and vegetation restoration in the study area.
