| 1 | 黄土高原苜蓿-冬小麦轮作系统土壤水分时空动态及产量响应显示文摘2 0 0 1~ 2 0 0 3年在甘肃庆阳黄土高原连续 3 a研究了紫花苜蓿 -冬小麦轮作系统中土壤 0~ 3 0 0 cm剖面水分动态特征 ,作物产量及其含 N量。处理包括 4龄苜蓿草地 (L C)、4龄苜蓿草地后茬持续休闲 (L F)、4龄苜蓿草地休闲 4个月后种植冬小麦(L Fl W) ,和 4龄苜蓿草地休闲 1个月后种植冬小麦 (L Fs W)。结果表明 ,种植 4a苜蓿后春季翻挖实施休闲至冬小麦播种(L Fl W)的 4个月期间 ,降雨的入渗深度为 150 cm,而苜蓿秋季翻挖休闲至小麦播种 (L Fs W)的一个月间 ,降雨在土壤内的入渗深度为 90 cm,不同休闲长度对头茬冬小麦土壤 0~ 90 cm水分贮存量无显著影响 ,亦不影响头茬冬小麦的出苗和出苗数。苜蓿后茬完全休闲 (L F)一个生长季后 ,60~ 90 cm土壤水分含量达田间最大重力持水量 (Drainage U pper L imit DU L )的 93 % ,0~ 3 0 0cm剖面土壤贮水量达 670 mm ,是剖面田间最大重力持水量 (DUL )的 78% ;L Fl W和 L Fs W处理下头茬小麦籽粒产量之间差异显著 (P<0 .0 5) ,收获指数和千粒重等指数无显著差异 ;L Fl W和 L Fs W处理中获得的二茬小麦产量无显著差异 ;连续种植苜蓿与种植小麦有接近的生物量 ,但苜蓿地植物总 N的输出量较小麦田高 2~ 3倍。由于黄土高原降雨变率大 ,因此预测土壤含水量动态有? | 沈禹颖 南志标 高崇岳 Bellotti W.D 陈文 | 2004 | 生态学报2004，24，3： | 30 |
| 2 | A study on 3-D velocity structure of crust and upper mantle in Sichuan -Yunnan region, China显示文摘Based on the first arrival P and S data of 4 625 regional earthquakes recorded at 174 stations dispersed in the Yunnan and Sichuan Provinces, the 3-D velocity structure of crust and upper mantle in the region is determined, incorporating with previous deep geophysical data. In the upper crust, a positive anomaly velocity zone exists in the Sichuan basin, whereas a negative anomaly velocity zone exists in the western Sichuan plateau. The boundary between the positive and negative anomaly zones is the Longmenshan fault zone. The images of lower crust and upper mantle in the Longmenshan fault, Xianshuihe fault, Honghe fault and others show the characteristic of tectonic boundary, indicating that the faults likely penetrate the Moho discontinuity. The negative velocity anomalies at the depth of 50 km in the Tengchong volcanic area and the Panxi tectonic zone appear to be associated with the temperature and composition variations in the upper mantle. The overall features of the crustal and the upper mantle structures in the SichuanYunnan region are the lower average velocity in both crust and uppermost mantle, the large crustal thickness variations, and the existence of high conductivity layer in the crust or/and upper mantle, and higher geothermal value. All these features are closely related to the collision between the India and the Asia plates. The crustal velocity in the SichuanYunnan rhombic block generally shows normal value or positive anomaly, while the negative anomaly exists in the area along the large strike-slip faults as the block boundary. It is conducive to the crustal block side-pressing out along the faults. In the major seismic zones, the seismicity is relative to the negative anomaly velocity. Most strong earthquakes occurred in the upper-mid crust with positive anomaly or normal velocity, where the negative anomaly zone generally exists below. | 王椿镛 Mooney W.D 王溪莉 吴建平 楼海 王飞 | 2002 | Acta Seismologica Sinica(English Edition)2002，15，1： | 5 |

| 5 | Variable retention harvesting in Great Lakes mixed-pine forests: emulating a natural model in managed ecosystems显示文摘Variable retention harvesting(VRH)systems have gained wide use in many different forest types across the globe,but largely have been implemented in forests characterized by severe,infrequent disturbance regimes.There has been less attention given to developing VRH approaches in forests that are characterized as having a mixed-severity disturbance regime that often results in only partial mortality of canopy trees in spatially heterogeneous patterns.One example of such a forest type is red pine(Pinus resinosa Ait.)-dominated ecosystem of the western Great Lakes region of North America.The purpose of this review is to provide a conceptual foundation for developing VRH approaches in red pine ecosystems that are based on a mixed-severity disturbance regime.Our contention is that red pine forests managed following a natural model are more resilient to disturbances and external threats such as climate change.For the red pine ecosystem,VRH application should reflect the often severe,but partial canopy removal from natural disturbance that is characteristic of this ecosystem and that results in more than trivial numbers of surviving overstory trees across a range of spatial configurations in regenerating stands.Retained live trees should span a range of diameters,but favor the larger end of the diameter distribution,as this reflects the likely pattern of survival after natural disturbance and is often a key structural element lacking from managed areas.VRH should be applied in ways that vary the spatial pattern of legacy trees in and among stands,but largely in ways that reflect the pattern of spatially patchy canopy structure,with large openings surrounded by a less disturbed matrix,as occurs with a natural disturbance regime.Legacy trees and deadwood structures should reflect the composition of the pre-disturbance forest,including species in addition to dominant red pine.Finally,retained structures should be viewed as dynamic entities that grow,die,and decay and that need to be documented and accounted for over time.While more organizations are incorporating some form of VRH into policy and practice for red pine-dominated ecosystems,this application is not always based on a comprehensive understanding of the actual natural model of development,which reflects a mixed-severity disturbance regime.Our goal is to review the ecological evidence for this disturbance regime and interpret the structural and compositional outcomes of the disturbance model,so as to advance VRH approaches that better emulate the actual disturbance and development model for this regionally important ecosystem. | Brian J.Palik Anthony W.D’Amato | 2019 | Ecological Processes2019，8，1： | 3 |
