摘要
为分析山东省植被覆盖度变化及其与降水量、温度等气候因子变化的相关性,该文采用2005-2015年的NDVI、降水量和温度数据,利用重心模型和相关系数法,进行了植被覆盖度与降水、温度的月动态变化和季度动态变化分析。研究结果显示,在2005-2015年的10年间,山东省植被覆盖度在整体上呈现增长趋势,植被覆盖度与气候因子无论是在月动态变化还是季动态变化都表现出不同程度的正相关性,植被NDVI的季度走向与降水和温度的季动态变化趋势几乎一致,并且温度对植被生长的影响大于降水对植被生长的影响。研究验证了植被覆盖度的变化与气候因子的变化有一定的关系。
In order to analyze the change of vegetation coverage in Shandong province and its correlation with climatic factors such as precipitation and temperature,based on NDVI,precipitation and temperature data from 2005 to 2015,using the gravity center model and correlation coefficient method,the relationship between vegetation coverage and precipitation,temperature dynamics and quarterly dynamics were analyzed.The results showed that from 2005 to 2015 for nearly 10 years,Shandong province on the whole,vegetation coverage growth trend,vegetation coverage and climate factors in both month dynamic change and dynamic change of season showed different degrees of positive correlation,vegetation NDVI quarter to season dynamic is almost uniformly with change trend of precipitation and temperature,and the influence of temperature on the vegetation growth is greater than the influence of precipitation on vegetation growth.The research in this paper verifies that the change of vegetation coverage has a certain relationship with the change of climate factors.
