Abstract：
Climate and human activities are the basic driving forces that control and influence the spatial distribution and change of vegetation. Using trend analysis, the Hurst index, correlation analysis, the Moran index, path analysis, residual analysis, and other methods, the effects of human activities and climate factors on vegetation change were analyzed. The results show that: (1) The research area\'s normalized difference vegetation index (NDVI) exhibited a substantial upward trend from 2001 to 2020, increasing at a rate of 0.003/a, and the vegetation cover was generally healthy. The generally constant NDVI region made up 78.45% of the entire area, and the grassland, cultivated land, and forest land showed the most visible NDVI aggregation features. (2) The Vegetation is mainly promoted by water and heat, particularly precipitation, have a major impact on plants, with the direct influence of precipitation on vegetation growth being much greater than the indirect effect through the temperature. (3) The trend of NDVI residuals showed obvious spatial variability, presenting a distribution characteristic of high in the south and low in the north. The results of this study can provide a basis for the scientific layout of ecological protection and restoration projects in the Yinshanbeilu area.
摘要：
气候和人类活动是控制和影响植被空间分布和变化的基本驱动力。使用趋势分析，赫斯特指数,相关分析，莫兰指数,路径分析,残差分析，和其他方法，分析了人类活动和气候因素对植被变化的影响。结果表明:(1)研究区的归一化植被指数(NDVI)在2001-2020年呈大幅度上升趋势,以0.003/a的速度上升,植被总体上是健康的。通常恒定的NDVI区域占整个区域的78.45％，还有草原,耕地,林地表现出最明显的NDVI聚集特征。(2)植被主要由水和热促进,尤其是降水,对植物有重大影响，降水对植被生长的直接影响远大于温度的间接影响。(3)NDVI残差呈现明显的空间变异性,呈现南高北低的分布特征。本研究结果可为银山北麓地区生态保护与修复工程的科学布局提供依据。
