加大经费投入 提高人员素质——我市全面提升矿管所履行职责能力的做法

我局对基层矿管站比较重视,尤其是2005年以来,我们以硬件达标,软件提升为重点,加大投入,强化培训,全面加强基层站所建设。目前九个基层所全部实现了机构属政府,人员有编制,经费进财政,其中有四个基层矿产资源管理所被升格为副科级单位。加大投入,从五个方面全面加强矿管所硬件建设我们按照“科学规划,严格标准,加大投入,一步到位”的原则,高标准、高质量建设基层站所。投资200余万元,按照统一的标准,建设了办公区、生活区、活动区。目前,我局的矿产资源管理所已全部达到五有,实现了规范化、标准化。一有固定的办公场所。9个矿产资源管理所共…     

Nitrogen and Phosphorus Budget of a Polyculture System of Sea Cucumber （Apostichopus japonicus）, Jellyfish （Rhopilema esculenta） and Shrimp （Fenneropenaeus chinensis）

The nitrogen(N) and phosphorus(P) budget and the ecological efficiency of a polyculture system of sea cucumber(Apostichopus japonicus), jellyfish(Rhopilema esculenta) and shrimp(Fenneropenaeus chinensis) were studied in a cofferdam, 120.2 ha in size. The nutrients were supplied by spring tide inflow. In total, 139600 kg N yr-1 and 9730 kg P yr-1 input to the system; while 118900 kg N yr-1 and 2840 kg P yr-1 outflowed from the system concurrently, thus the outflow was 85.7%(N) and 29.2%(P) of inflow. The production of N and P was 889.5 kg yr-1 and 49.28 kg yr-1(sea cucumber) and 204 kg yr-1 and 18.03 kg yr-1(jellyfish and shrimp), respectively. The utilization rate of N and P by polycultured animals was 7.8‰ and 6.9‰, respectively, 21.9% and 38% higher than that of monocultured sea cucumber. Our results indicated that the polyculture system was an efficient culture system of animals and a remediation system of coastal environment as well; it scavenged 14.3% and 70.8% of N and P, respectively. Such an ecological efficiency may be improved further by increasing either the stocking density or the size of sea cucumber or both.     

用水文地质比拟法预算矿井涌水量

根据大同煤田赋存有侏罗系和石炭二叠系两套含煤建造的特点,以大同煤田马脊梁勘探区为例,运用水文地质比拟法,分别采用邻矿(塔山煤矿)、勘探区上覆的煤矿(侏罗系煤矿)矿井涌水量观测资料,在充分讨论勘探区与对比煤矿的比拟条件后,较为恰当地求得了比拟参数,对勘探区矿井涌水量进行了预算,得出了较为接近的比拟结果。     

Wave breaking on turbulent energy budget in the ocean surface mixed layer

As an important physical process at the air-sea interface, wave movement and breaking have a significant effect on the ocean surface mixed layer （OSML）. When breaking waves occur at the ocean surface, turbulent kinetic energy （TKE） is input downwards, and a sublayer is formed near the surface and turbulence vertical mixing is intensively enhanced. A one-dimensional ocean model including the Mellor-Yamada level 2.5 turbulence closure equations was employed in our research on variations in turbulent energy budget within OSML. The influence of wave breaking could be introduced into the model by modifying an existing surface boundary condition of the TKE equation and specifying its input. The vertical diffusion and dissipation of TKE were effectively enhanced in the sublayer when wave breaking was considered. Turbulent energy dissipated in the sublayer was about 92.0% of the total depth-integrated dissipated TKE, which is twice higher than that of non-wave breaking. The shear production of TKE decreased by 3.5% because the mean flow fields tended to be uniform due to wave-enhanced turbulent mixing. As a result, a new local equilibrium between diffusion and dissipation of TKE was reached in the wave-enhanced layer. Below the sublayer, the local equilibrium between shear production and dissipation of TKE agreed with the conclusion drawn from the classical law-of-the-wall （Craig and Banner, 1994）.     

清镇市防雹减灾工作若干问题的思考

长期以来 ,冰雹对清镇市人民的生产生活构成了严重的威胁。由于降雹的高峰期都在生产的关键季节 ,特别是油菜、小麦等小春作物从结实到收获和烤烟、水稻育苗 (秧 )的4～ 5月 ,降雹机率高 ,强度大 ,危害也最为严重。而且下午至傍晚的降雹频率高 ,地方性、突发性特别强 ,让人防不胜防。而每次受灾之后 ,各级党委、政府的领导同志和有关部门的同志 ,都要奔赴灾区 ,慰问灾民 ,投入大量的人力物力财力进行救助。因此 ,转变思想观念和改进工作方法 ,采取更为积极有力的措施防雹避灾 ,尽可能地减少雹灾给国家和人民群众造成的损失 ,发展生产 ,变被…     

黄土高原北部神府东胜矿区暴雨过程动态设计

应用水文学雨型动态设计原理,根据黄土高原北部神府东胜矿区暴雨特征,分析计算出该地区不同雨强不同重现期的暴雨量,并按照矿区最大1 h、6 h、12 h和24 h暴雨记录,采用不同历时曲线的主雨峰对齐、算术平均、滑动挑选的方法,分析概化出矿区不同时段每年一遇的暴雨历时控制雨型,绝大部分高强度暴雨均属于超前型。应用暴雨动态过程设计方法,可以计算分析无气象、水文测站的每一个小流域的暴雨过程。从而为流域产流汇流、侵蚀量的计算奠定了基础,并使所计算出的流量和侵蚀量更有可用性。
