中文摘要: 基于20002013年的MODIS NDVI数据反演广西九万山国家级自然保护区的植被覆盖变化,结合当地气温、降水数据,分别从年、季、月三个时间变化角度来分析区域内植被变化对气候因子的响应。结果表明,从年际相关关系来看,年降水量是造成植被覆盖度变化的主要因素,相较于气温更能反应植被生长的整体趋势;从季节角度来看,春季植被变化主要受到气温的影响,夏季和秋季植被变化程度受当月降水影响明显;从月变化关系来看,3月、4月植被生长受当月气温变化影响较大,从5月起植被生长状况对气温的变化表现出一定的滞后性但不显著,5?11月当月降水量是影响该地区植被生变化的主要因素;该地区2009年出现严重旱情,NDVI达到13年来最低值,而2010年植被覆盖基本恢复到平均水平。综上所述,气候因子对九万山自然保护区植被生长有着直接的影响关系,可以通过监测气候要素的变化来预测植被生长的状况。
英文摘要: Based on the continuous MODIS data from 2000 to 2013 extract the time series characteristics of vegetation change conditions in Jiuwan mountain. The responses of vegetation coverage and the growth condition changes to the climatic variations from the yearly, seasonal and monthly time scales were analyzed combined with temperature and precipitation data form meteorological sites. In the past 13 years, vegetation coverage change was closely correlated with climatic factors. Annual precipitation is the main factor driving changes in vegetation which was better correlated than temperature. Correlations between seasonal average of vegetation coverage and climatic factors showed that the spring vegetation growth is mainly affected by temperature changes than other season, summer and autumn vegetation changes obviously affected by monthly precipitation; Correlations between monthly average of vegetation coverage and climatic factors during growing seasons showed that vegetation growth are greatly influenced by the temperature change during March and April, indicating that the temperature effect occurred in the early stage of vegetation growth. From May, the vegetation change in response to temperature changes show some lag but not significant, and the region vegetation growth was mainly affected by precipitation during the month. In summary, climatic factors has a direct effect on vegetation growth, the situation of vegetation growth could be specific revealed by monitoring the change of climate.
