There is a close relationship between vegetation distribution and climate pattern in grassland areas, and offering insights into the climate-vegetation relationship may provide significant references for in-depth research on the response of plant community dynamics to climate change. In this study, we took the edge of the Jiangjiadian grassland in China as the research area. Using plant plots and climate data, the climate-vegetation relationship was revealed in relation to climate change on the grassland edge. The research results show that the relative frequency (RF), density (RD), height (RH), and coverage (RC) of , a typical wetland plant, are the highest among the 10 common species tested. The path coefficient of mean temperature in October (MMTO) to the RD is 0.06 ( < 0.01), and the path coefficient of precipitation in October (POct) to the relative height (RH) is 0.62 ( < 0.05), indicating that the spatial pattern of climate has a significant impact on plant distribution. The temperature and the precipitation increases are associated with the trend regarding the transformation from grassland to wetland. Overall, 34 of the 360 correlation coefficients between climate indices and plant indices reached a significant level ( < 0.05), indicating that the relationship between wetland trends and the climate spatial pattern is very complex in relation to climate change in the past 25 years.
草原地区植被分布与气候格局之间存在密切关系，深入了解气候与植被的关系可为深入研究植物群落动态对气候变化的响应提供重要参考。在本研究中，我们以中国蒋家店草原边缘为研究区域。利用植物样地和气候数据，揭示了草原边缘气候变化下的气候-植被关系。研究结果表明，在测试的10种常见物种中，典型湿地植物的相对频度（RF）、密度（RD）、高度（RH）和盖度（RC）最高。10月平均温度（MMTO）对RD的通径系数为0.06（P<0.01），10月降水量（POct）对相对高度（RH）的通径系数为0.62（P<0.05），表明气候的空间格局对植物分布有显著影响。温度和降水量的增加与从草原向湿地转变的趋势相关。总体而言，在过去25年气候变化方面，气候指数与植物指数之间360个相关系数中有34个达到显著水平（P<0.05），表明湿地变化趋势与气候空间格局之间的关系非常复杂。
