中国东部南北样带森林生态系统WUE和NUE空间格局及驱动因子(英文) 总被引:3,自引:1,他引:3
From July 2008 to August 2008, 72 leaf samples from 22 species and 81 soil samples in the nine natural forest ecosystems were collected, from north to south along the North-South Transect of Eastern China (NSTEC). Based on these samples, we studied the geographical distribution patterns of vegetable water use efficiency (WUE) and nitrogen use efficiency (NUE), and analyzed their relationship with environmental factors. The vegetable WUE and NUE were calculated through the measurement of foliar δ 13C and C/N of predominant species, respectively. The results showed: (1) vegetable WUE, ranging from 2.13 to 28.67 mg C g-1 H2O, increased linearly from south to north in the representative forest ecosystems along the NSTEC, while vegetable NUE showed an opposite trend, increasing from north to south, ranging from 12.92 to 29.60 g C g-1 N. (2) Vegetable WUE and NUE were dominantly driven by climate and significantly affected by soil nutrient factors. Based on multiple stepwise regression analysis, mean annual temperature, soil phosphorus concentration, and soil nitrogen concentration were responding for 75.5% of the variations of WUE (p<0.001). While, mean annual precipitation and soil phosphorus concentration could explain 65.7% of the change in vegetable NUE (p<0.001). Moreover, vegetable WUE and NUE would also be seriously influenced by atmospheric nitrogen deposition in nitrogen saturated ecosystems. (3) There was a significant trade-off relationship between vegetable WUE and NUE in the typical forest ecosystems along the NSTEC (p<0.001), indicating a balanced strategy for vegetation in resource utilization in natural forest ecosystems along the NSTEC. This study suggests that global change would impact the resource use efficiency of forest ecosystems. However, vegetation could adapt to those changes by increasing the use efficiency of shortage resource while decreasing the relatively ample one. But extreme impacts, such as heavy nitrogen deposition, would break this trade-off mechanism and give a dramatic disturbance to the ecosystem biogeochemical cycle. 相似文献

藏北地区气候变化特征及其影响分析 总被引:8,自引:0,他引:8
藏北地区地域广阔、地势高,自然条件极为严酷,其环境状况直接影响到我国的江河、气候及生态环境,甚至对全球也有不容忽视的影响。本研究选取藏北地区有长期、连续记录的5个气象站点,分析藏北地区近40年来的气候变化特征,并对其可能影响进行分析。藏北地区近40年来温度上升趋势明显,尤其是最低温度的升温率达0.79℃.(10a-1),高于青藏高原的平均水平;降水的年际波动大,自20世纪90年代以后明显增多。近40年藏北地区的气候有暖湿化趋势,这将有利于该地区的动、植物生长,但是该地区冰川冻土面积大,气温升高会引起冰川退缩和冻土层融化,又将给藏北地区脆弱的生态系统带来不利影响。 相似文献
