1辽西医巫闾山地区瓦子峪变质核杂岩的厘定(英文)显示文摘以前未被发现的辽西医巫闾山地区瓦子峪变质核杂岩主要由一条向西倾的低角度正断层———瓦子峪拆离断层组成 ,它将由早白垩世沉积岩和火山岩组成的上盘与糜棱岩化和未变形的下盘分开。瓦子峪拆离断层 (以前称之为孙家湾—稍户营子断裂 )位于变质核杂岩的西侧 ,倾角 10~ 4 0°,构造标志指示向北西方向 (约 2 90°)剪切。与早白垩世地壳伸展相伴生的下盘糜棱岩剪切方向也是北西向 ,这与瓦子峪拆离断层运动相关。已经发表的和未发表的锆石U Pb年龄、40 Ar/3 9Ar热年代学和上盘阜新盆地中生物地层的时代研究表明 ,地壳伸展和变质核杂岩形成时代为早白垩世 (约 12 7~ 116Ma)。我们未发现以前文献报道的医巫闾山是一对称的变质核杂岩的任何证据。瓦子峪变质核杂岩以及WNW侧的拆离断层的厘定会加深我们对华北克拉通早白垩世伸展作用的理解和认识 ,下一步的研究重点包括野外构造研究以确定拆离断层和下盘糜棱岩的空间展布 ,进一步采集样品以研究变质核杂岩的地质 /热年代学和变质核杂岩范围内的岩体成因。我们认为瓦子峪变质核杂岩的形成是太平洋板块边界重组、早白垩世岩浆作用致使地壳升温 ,从而导致经造山作用而加厚的地壳垮塌的结果。Brian J.

2Spatial Variability of Nutrient Properties in Black Soil of Northeast China显示文摘A total of 1400 soil samples from the plow layer (0-20 cm) at an approximate interval of 5 km were collected in the autumn of 2002 over the entire black soil arable crops region to determine the spatial variability of seven variables, such as total organic matter content (OMC), total N, total P, total K, alkali-dissolvable N (AN), available P (AP) and available K (AK), with classical statistics and geostatistical analysis across the entire black soil area in Northeast China. In nonsampled areas ordinary kriging was utilized for interpolation of estimated nutrient determinations. Classical statistics revealed highly significant (P≤0.01) correlations with all seven of the soil properties, except for OMC with AP and total K with AK. In addition, using coefficients of variation, all soil properties, except for total K, were moderately variable. A geostatistical analysis indicated that structural factors, such as parent material, terrain, and water table, were the main causes of the spatial correlations. Strong spatial correlations were noted with OMC, total N, total P, AN, and AP, while they were moderate for total K and AK. The effective spatial autocorrelation of OMC, total N, total P, and AN ranged from 1 037 to 1 353 km, whereas the ranges of total K, AP, and AK were only from 6 to 138 km. The fit of the experimental semi-variograms to the theoretical models indicated that except for AN, kriging could successfully interpolate other six variables. Thus, the geostatistical method used on a large scale could accurately evaluate the spatial variability of most black soil nutrient properties in Northeast China.ZHANG Xing-Yi SUI Yue-Yu ZHANG Xu-Dong MENG Kai S.

11Responses of Soil Microbial Community Structure and Diversity to Agricultural Deintensification显示文摘Using a scheme of agricultural fields with progressively less intensive management (deintensification), different manage- ment practices in six agroecosystems located near Goldsboro, NC, USA were tested in a large-scale experiment, including two cash-grain cropping systems employing either tillage (CT) or no-tillage (NT), an organic farming system (OR), an integrated cropping system with animals (IN), a successional field (SU), and a plantation woodlot (WO). Microbial phos- pholipid fatty acid (PLFA) profiles and substrate utilization patterns (BIOLOG ECO plates) were measured to examine the effects of deintensification on the structure and diversity of soil microbial communities. Principle component analyses of PLFA and BIOLOG data showed that the microbial community structure diverged among the soils of the six systems. Lower microbial diversity was found in lowly managed ecosystem than that in intensive and moderately managed agro- ecosystems, and both fungal contribution to the total identified PLFAs and the ratio of microbial biomass C/N increased along with agricultural deintensification. Significantly higher ratios of C/N (P < 0.05) were found in the WO and SU systems, and for fungal/bacterial PLFAs in the WO system (P < 0.05). There were also significant decreases (P < 0.05) along with agricultural deintensification for contributions of total bacterial and gram positive (G+) bacterial PLFAs. Agricultural deintensification could facilitate the development of microbial communities that favor soil fungi over bacteria.ZHANG Wei- Jian RUI Wen-Yi C. TU H. G. DIAB F. J. LOUWS J. P. MUELLER N.

13Predicting Nitrogen Status of Rice Using Multispectral Data at Canopy Scale显示文摘Two field experiments were conducted in Jiashan and Yuhang towns of Zhejiang Province, China, to study the feasibility of predicting N status of rice using canopy spectral reflectance. The canopy spectral reflectance of rice grown with different levels of N inputs was determined at several important growth stages. Statistical analyses showed that as a result of the different levels of N supply, there were significant differences in the N concentrations of canopy leaves at different growth stages. Since spectral reflectance measurements showed that the N status of rice was related to reflectance in the visible and NIR (near-infrared) ranges, observations for rice in 1 nm bandwidths were then converted to bandwidths in the visible and NIR spectral regions with IKONOS (space imaging) bandwidths and vegetation indices being used to predict the N status of rice. The results indicated that canopy reflectance measurements converted to ratio vegetation index (RVI) and normalized difference vegetation index (NDVI) for simulated IKONOS bands provided a better prediction of rice N status than the reflectance measurements in the simulated IKONOS bands themselves. The precision of the developed regression models using RVI and NDVI proved to be very high with R2 ranging from 0.82 to 0.94, and when validated with experimental data from a different site, the results were satisfactory with R2 ranging from 0.55 to 0.70. Thus, the results showed that theoretically it should be possible to monitor N status using remotely sensed data.ZHANG Jin-Heng WANG Ke J. S. BAILEY WANG Ren-Chao 2006Pedosphere2006,16,1:26

16Impact of Land Use and Soil Fertility on Distributions of Soil Aggregate Fractions and Some Nutrients显示文摘The size distribution of water-stable aggregates and the variability of organic C,N and P contents over aggregate size fractions were studied for orchard,upland,paddy,and grassland soils with high,medium,and low fertility levels.The results showed that > 5 mm aggregates in the cultivated upland and paddy soils were 44.0% and 32.0%,respectively,less than those in the un-tilled orchard soil.Organic C and soil N in different size aggregate fractions in orchard soil with high fertility were significantly higher than those of other land uses.However,the contents of soil P in different size aggregates were significantly greater in the paddy soil as compared to the other land uses.Soil organic C,N and P contents were higher in larger aggregates than those in smaller ones.The amount of water-stable aggregates was positively correlated to their contribution to soil organic C,N and P.For orchard and grassland soils,the > 5 mm aggregates made the greatest contribution to soil nutrients,while for upland soil,the 0.25-0.053 mm aggregates contributed the most to soil nutrients.Therefore,the land use with minimum disturbance was beneficial for the formation of a better soil structure.The dominant soil aggregates in different land use types determined the distribution of soil nutrients.Utilization efficiency of soil P could be improved by converting other land uses to the paddy soil.LIU Xiao-Li HE Yuan-Qiu H.
