浙江乌岩岭7种林分土壤碳密度及碳氮比分布特征

【目的】探究浙江乌岩岭自然保护区7种林分(松林、杉木林、柳杉林、阔叶林、混交林、竹林、茶园)土壤的总碳(TC)密度、有机碳(SOC)密度及土壤碳氮比(C/N)的分布特征,为提高土壤碳库管理水平提供参考。【方法】用TOC-L_CPH总有机碳分析仪测定了该区7种林分土壤TC与SOC含量,核算相应的土壤碳密度及C/N,并分析土壤TC密度、SOC密度及C/N与部分土壤理化参数的关系。【结果】乌岩岭自然保护区各林分0～40 cm土层SOC密度为84.53～183.26 t/hm²,平均值为118.06 t/hm²,以杉木林最高。除杉木林0～10 cm土层C/N高于25外,其余土层及其他林分土壤C/N为8.32～21.88。乌岩岭自然保护区各土层TC密度、SOC密度及C/N在7种林分间均无显著性差异(P>0.05)。土壤TC密度及C/N都呈现出随土层深度增加而减少的规律,具有明显的表聚特征,不同土层间差异显著(P<0.05)。土壤TC密度、SOC密度与土壤速效钾(AK)含量之间存在显著正相关(P<0.05),土壤C/N与土壤有效钾(AK)含量间存在极显著正相关(P<0.01)。【结论】乌岩岭自然保护区土壤AK含量可作为土壤TC密度、SOC密度及C/N共同的重要指示因子。

Asynchronous parallel evolutionary algorithms for constrained optimizations

Recently Guo Tao proposed a stochastic search algorithm in his PhD thesis for solving function optimization problems. He combined the subspace search method (a general multi-parent recombination strategy) with the population hill-climbing method. The former keeps a global search for overall situation, and the latter keeps the convergence of the algorithm. Guo's algorithm has many advantages, such as the simplicity of its structure, the higher accuracy of its results, the wide range of its applications, and the robustness of its use. In this paper a preliminary theoretical analysis of the algorithm is given and some numerical experiments has been done by using Guo's algorithm for demonstrating the theoretical results. Three asynchronous parallel evolutionary algorithms with different granularities for MIMD machines are designed by parallelizing Guo's Algorithm.

Zircon SHRIMP U-Pb geochronology and petrogenesis of the plagiogranites from the Lagkor Lake ophiolite, Gerze, Tibet, China

Field relationship, along with petrographical, petrological, and geochemical characteristics, and zircon populations, indicates that the plagiogranites from the Lagkor Lake ophiolite in the Bangong-Nujiang suture zone (~ 20 km south of Gerze County, central Tibet, China), derived from anatexis of hydrated gabbros by ductile shearing during transport of the oceanic crust. Therefore, this kind of plagiogranite is coeval to or little later than the spreading of the oceanic crust. Zircon SHRIMP age of 166 ± 2.5 Ma for the plagiogranites indicates that an oceanic basin existed in the western part of the Bangong-Nujiang zone in the Middle Jurassic.     

Metallogenetic epoch and mechanism of the tungsten ore in Yushan,Beishan orogenic belt,Gansu

Using SHRIMP zircon U-Pb dating methods and cathodoluminescence （CL） technique, we have precisely dated ore samples from tungsten ore deposit, ore-bearing volcanic-sedimentary strata and granite in the Yushan region within the east Tianshan-Beishan W-bearing zone. This study reveals Yushan tungsten ore deposit zone formed in 250 ± 9 Ma, and it is closely associated with the Permian granites and felsic volcanic rocks. This new type of tungsten ore deposit in the east Tianshan-Beishang multiple-metallogenetic province may probably be associated with the regionally right-literal shearing after the main Carboniferous collisional orogeny, and the formation of pull-apart basin and the felsic magmatism.     

Some massively parallel algorithms from nature

We introduced the work on parallel problem solvers from physics and biology being developed by the research team at the State Key Laboratory of Software Engineering, Wuhan University. Results on parallel solvers include the following areas: Evolutionary algorithms based on imitating the evolution processes of nature for parallel problem solving, especially for parallel optimization and model-building; Asynchronous parallel algorithms based on domain decomposition which are inspired by physical analogies such as elastic relaxation process and annealing process, for scientific computations, especially for solving nonlinear mathematical physics problems. All these algorithms have the following common characteristics: inherent parallelism, self-adaptation and self-organization, because the basic ideas of these solvers are from imitating the natural evolutionary processes.

Preparation and characterization of three-dimensionally ordered macroporous polystyrene <Emphasis Type="Italic">via</Emphasis> atom-transfer radical polymerization

Three-dimensionally ordered macroporous polystyrene （3DOM PS） with pore size of 350 nm was fab- ricated using Cp2Co/Ethyl 2-bromoisobutyrate （EBiB） catalytic system by ATRP. The resulting polymers were detected by FT-IR, 1H-NMR, SEM, and GPC. The microstructure of 3DOM PS was confirmed by FT-IR and 1H-NMR. SEM micrographs show that both silica spheres within the templates and pores in the 3DOM polystyrene are arranged in highly ordered fashion, and the shrinkage of the pores in the 3DOM PS is 24%. GPC curves show that the 3DOM PS possesses slightly lower Mn and narrow MWD compared with bulk one. This result indicats that living polymerization is different from non-living polymerizationin in the confined space.

Exsolution microstructures in ultrahigh-pressure rocks: Progress, controversies and challenges

Exsolution microstructures in minerals of rocks from orogenic belts played an important role in recognition of ultrahigh-pressure （UHP） metamorphism in their host rocks by defining the subduction depth and improving our understanding of the dynamics during the subduction and exhumation of UHP rocks. However, it is a challenging scientific topic to distinguish the ＇exsolution microstructures＇ from the ＇non-exsolution microstructures＇ and decipher their geological implications. This paper describes the subtle differences between the ＇exsolution microstructures＇ and the ＇non-exsolution microstructures＇ and summarizes the progress in studies of exolution microstructures from UHP rocks and mantle rocks of ultra-deep origin. We emphasize distinguishing the ＇exsolution microstructures＇ from the ＇non-exsolution microstructures＇ based on their geometric topotaxy and chemistry. In order to decipher correctly the exsolution microstructures, it is crucial to understand the changes of chemistry and habits of host minerals with pressure and temperature, Therefore, it is important to combine observations of exsolution microstructure in natural rocks with experimental results at high pressure and temperature and results of micro-scale analyses. Such studies will improve our understanding of the UHP metamorphism and cast new lights on solid geoscience issues such as deep subduction of continental crusts and crust-mantle interactions.     

Wetland ecosystem function assessment and the sustainable development in Jianghan plain-lake district of China

Wetlands in Jianghan plain-lake district fulfill many uses and functions related to hydrology, waste assimilation, ecosystem productivity and bio-diversity. But human incorrect activities generally result in significant negative impacts on number, biodiversity, and functioning of wetlands. In order to put wetland resources to rational use and protect wetland ecological environment, some effective measures should be taken.

Coexistence of normal, super-, and hyper-deformation in nuclei: A study with angular momentum projection method

Angular-momentum-projected energy surface calculations for A ≈ 110 nuclei indicate three distinct energy minima occurring at different angular-momenta. These correspond to normal, super-, and hy- per-deformed shapes coexisting in one nucleus. 110Pd is studied in detail, with a quantitative prediction on super- and hyper-deformed spectra by the Projected Shell Model calculation. It is found that several other neighboring nuclei in the A-110 mass region, with the neutron number around 64, also exhibit clear s...     

Well-defined bis（phenolate） lanthanide methoxides as efficient initiators for the polymerization of cyclic carbonate and lactide

Lanthanide methoxides supported by carbon-bridged bis(phenolate) ligands 2,2′-methylene-bis(6-tert- butyl-4-methylphenoxo) (MBMP2-) [(MBMP)Ln( μ-OMe)(THF)2]2 (Ln = Nd (1), Yb (2)) were synthesized in high yields by the protolysis reaction using (C5H5)3Ln(THF) as starting materials, and complex 1 was structurally characterized. The coordination geometry around the center metal can be best described as a distorted octahedron. Complexes 1 and 2 were shown to be efficient initiators for the ring-opening polymerization of 2,2-dimethyltrimethylene carbonate (DTC) and L-lactide. The mechanism of DTC polymerization was explored by the end group analysis of the oligomer.
