Abstract: Recurrence quantification analysis (RQA) and cross recurrence plot (CRP) are used to analyze the relationship between the normalized difference vegetation index (NDVI) and climatic factors in the Southwest and Southeast Monsoon Regions in Yunnan longitudinal range-gorge region (LRGR). Results show that in the Southwest Monsoon Region the NDVI series has a higher certainty than that in the Southeast Monsoon Region. The coupling relationships of NDVI series in the two regions are between a completely random series and a deterministic series with noise. The two NDVI series have low synchronization in general, especially in the period 1987?1989 and 1991?1993. The NDVI series of the Southwest Monsoon Region lags behind that of the Southeast Monsoon Region. According to the CRP indices, the similarity, persistence time and stability of the coupling relationship between NDVI and precipitation series in the Southwest Monsoon Region are better than that of the Southeast Monsoon Region. Both the NDVI series and temperature series have similar trends. However, the difference of the CRP indices between the two regions is smaller. It is suggested that the interaction pattern of NDVI and temperatures has a smaller difference between the two regions.

摘要： 以云南省纵向岭谷区南部西南季风区和东南季风区为例，采用定量递归(recurrence quantification analysis，RQA)和交叉递归图(cross recurrence plots, CRP)方法分析了NDVI和气候因子之间的相互关系。结果表明，云南省纵向岭谷区西南季风区NDVI系列的确定性高于其东南季风区，两区NDVI系列耦合关系的动力学特性介于完全随机系列与含有噪声的确定性系列之间。从整体上看，两区NDVI系列的同步性较差，特别是在1987?1989年和1991?1993年两个时段同步性最低，而且西南季风区NDVI系列的变化滞后于东南季风区。从两个季风区NDVI分别与降水、气温系列耦合关系的CRP指数看，西南季风区NDVI与降水关系的相似性及其延存时间、结构性以及稳定程度均高于东南季风区， NDVI与气温关系与上述趋势大体一致，但各CRP指数在两个气候区的差别更小，说明NDVI与气温相互作用的特征在两区差异较小。
