| 1 | 对气候变暖响应下土壤CO_2释放的估计过高——老龄土壤有机质的分解具耐温性显示文摘本研究预测,相对于植被的净初级生产力(NPP)来说,随着全球变暖,有机质分解速度加快,土壤有机碳的贮藏速度将减少。因为土壤碳的含量是目前大气含量的两倍,而且从土壤中分解的碳要释放到大气中,因此,土壤碳贮量的减少会大量增加大气CO_2浓度。但是,土壤碳贮量减少的预测在很大程度上依赖于这样的隐含假设:所有土镶有机质的分解像新鲜凋落物的分解一样对温度较为敏感。我们测定了土壤碳的数量和年龄,以及沿温度梯度的凋落物的分解,并用一个简单的模型来描述土壤碳的动态,以显示老土壤有机质的分解阻抗温度的变化。因此,在对气候变暖的响应下,我们估算的分解速度的加快比从前预计的明显要低,并且预测北方森林土壤碳的贮量将增加。 | Jari Liski Annikki Mkel Carl Johan Westman 李叙勇 | 1999 | 人类环境杂志1999，28，2： | 16 |

| 3 | Determination of volumetric changes at an underground stone mine: a photogrammetry case study显示文摘Photogrammetry,as a tool for monitoring underground mine deformation,is an alternative to traditional point measurement devices,and may be capable of accurate measurements in situations where technologies such as laser scanning are unsuited,undesired,or cost-prohibitive. An underground limestone mine in Ohio is used as a test case for monitoring of structurally unstable pillars. Seven pillars were photographed over in a 63 day period,punctuated by four visits. Using photogrammetry,point clouds of the mine geometry were obtained and triangulation surfaces were generated to determine volumes of change over time. Pillar spalling in the range of 0.29–4.03 m^3 of rock on individual rib faces was detected.Isolated incidents of rock expansion prior to failure,and the isolated failure of a weak shale band were also observed. Much of the pillars remained unchanged during the monitoring period,which is indicative of proper alignment in the triangulated surfaces. The photographs of some ribs were of either too poor quality or had insufficient overlap,and were not included. However,photogrammetry was successfully applied to multiple ribs in quantifying the pillar geometry change over time. | Slaker Brent Westman Erik Ellenberger John Murphy Michael | 2016 | International Journal of Mining Science and Technology2016，26，1： | 2 |
