| 摘 要： | 根据中国干湿区分布图,选取典型的干旱地区（额济纳地区）、半干旱/半湿润（关中盆地/黄土高原）和湿润地区（鄱阳湖地区）为研究区域。基于1982～2000年的NDVI数据和1981～2000年3个研究区气象观测资料,探讨了不同干湿分布区植被NDVI与气候因子（温度、降水）之间相互响应关系。结果表明,植被对气候因子的响应关系中,干旱地区（额济纳地区）植被对降水的变化较为敏感;半湿润/半干旱地区（关中盆地/黄土高原地区）植被对温度和降水的变化均较为敏感;而湿润地区（鄱阳湖地区）植被对温度的变化敏感;植被对气候因子的影响中,干旱地区（额济纳地区）前一年冬季植被NDVI与当年夏季温度、降水的分别呈显著的负、正相关;而半干旱/半湿润地区（关中盆地/黄土高原地区）当年植被NDVI与当年温度呈显著正相关。

| Abstract: | Using the distribution of arid and humid regions of China,the typical arid region (Ejina),the typical semi-arid/semi-humid region(Guangzhong basin/Loess Plateau)and the typical humid region(Poyang Lake basin) were selected as the study areas. Based on the NDVI datasets from 1982 to 2000 and the climatic factors datasets of three study areas from 1981 to 2000,the inactions between vegetation and climatic factors in typical and humid regions were discussed. The results showed that in the responses of vegetati... |
