梁北二井水文地质特征及充水因素探讨

通过对井田边界条件、主要含水层的富水特征、断层的水文地质特征以及地下水的补给、径流及排泄条件的分析研究,认为二1煤层顶板的直接充水水源为顶板砂岩裂隙水,底板的直接充水水源为石炭系太原组上段石灰岩岩溶裂隙水,底板的间接充水水源为石炭系下段太原组灰岩岩溶裂隙水和寒武系白云质灰岩岩溶裂隙水;矿井充水通道为顶板砂岩、底板灰岩的裂隙和断层带。采用大井法对先期开采地段二1煤层-700m水平的矿井涌水量进行了预算：正常涌水量为947m^3/d,最大涌水量为1140m^3/d。结合邻近矿井的调查,认为计算的涌水量是可靠的,可作为煤矿建井设计和水害防治的依据。     

地勘基金运行中面临的困难

2007年9月25日国土资源部中央地质勘查基金管理中心成立揭牌。它的建立是对我国50多年来地勘管理体制和地勘投资体制的一次重大变革。它打破了长期以来国家财政单一包揽地质勘查经费的模式,形成了多渠道投入地质勘查的机制,具有重大的意义。然而,它在运行过程中却存在着诸多问题。地勘基金的作用尚需统一据报道,目前个别省区地方政府     

Assessing the global averaged sea-level budget from 2003 to 2010

A global mass balance （Greenland and Antarctica ice sheet mass loss, terrestrial water storage） and differ- ent sea-level components （observed sea-level from satellite altimetry, steric sea-level from Ishii data, and ocean mass from gravity recovery and climate experiment, GRACE） are estimated, in terms of seasonal and interannual variabilities from 2003 to 2010. The results show that a detailed analysis of the GRACE time series over the time period 2003-2010 unambiguously reveals an increase in mass loss from the Greenland ice sheet and Antarctica ice sheet. The mass loss of both ice sheets accelerated at a rate of （392.8±70.0） Gt/a during 2003-2010, which contributed （1.09±0.19） mm/a to the global mean sea-level during this time. The net terrestrial water storage （TWS） trend was negative over the 8 a time span, which gave a small positive contribution of （0.25±0.12） mm/a. The interannual variability of the global mean sea-level was at least part- ly caused by year-to-year variability of land water storage. Estimating GRACE-based ice sheet mass balance and terrestrial water storage by using published estimates for melting glaciers, the results further show that the ocean mass increase since 2003 has resulted half from an enhanced contribution of the polar ice sheets, and half from the combined ice sheet and terrestrial water storage loss. Taking also into account the melt- ing of mountain glaciers （0.41 mm/a） and the small GRACE-based contribution from continental waters （0.25 mm/a）, a total ocean mass contribution of （1.75±0.57） mm/a from 2003 to 2010 is found. Such a value represented 75% of the altimetry-based rate of sea-level rise over that period. The contributions to steric sea-level （i.e., ocean thermal expansion plus salinity effects） are estimated from： （1） the difference between altimetry-based sea-level and ocean mass change and （2） the latest Ishii data. The inferred steric sea-level rate from （1） （1.41 mm/a from 2003 to 2010） did not agree well with the Ishii-based value also estimated here （0.44 mm/a from 2003 to 2010）, but phase. The cause for such a discrepancy is not yet known but may be related to inadequate sampling of in situ ocean temperature and salinity measurements.     

Uncertainty in Dust Budget over East Asia Simulated by WRF/Chem with Six Different Dust Emission Schemes

In this study, the dependence of dust budgets on dust emission schemes is investigated through the simulation of dust storm events, which occurred during 14–25 March 2002, over East Asia, by the Weather Research and Forecasting with Chemistry（WRF/Chem） model coupled with six dust emission schemes. Generally, this model can reasonably reproduce the spatial distribution of surface dust concentration; however, the simulated total dust budget differs significantly with different emission schemes. Moreover, uncertainties in the simulated dust budget vary among regions. It is suggested that the dust emission scheme affects the regional dust budget directly through its impact on the total emitted dust amount; however, the inflow and outflow of dust aerosols simulated by different schemes within a region also depend on the geographical location of the dust emission region. Furthermore, the size distribution of dust particles for a specific dust emission scheme has proven to be important for dust budget calculation due to the dependence of dust deposition amount on dust size distribution.     

浅谈土地确权中的测绘成本预算

预算在土地确权测绘工作中起着至关重要的作用,然而,现阶段测绘预算中存在着不符合实际、定额不健全、对象不明确、预算编制程序化等问题.要在资金有限的情况下保证高质量的测绘数据成果,就要对测绘工作进行系统化和精细化的预算.本文简单分析了现阶段测绘预算中存在的问题,并介绍了如何从分析整理前期数据和当地实际工作情况两个方面对农村集体土地确权测绘工作进行成本预算.     

浅议公共支出预算管理制度改革

公共支出预算是政府在一个财政年度内为满足公共需要，提高给社会成员大体均等的公共服务所需开支计划，是政府财政活动及公共财政预算的一个重要组成部分。它反映了政府活动的范围，方向和政策，也决定了公共支出的流量和流向。按照市场经济的一般理论，政府负责的事项和活动范围主要是通过介入“市场失效”领域，

厦门星海湾丁宜山挡土墙工程适宜性探讨

拟建的高层商住楼设置1～2层的地下室.工程布局存在两种方案,一种方案是将地下室开挖出的大量土方,堆筑到丁宜山上,在山顶上建设相对独立和封闭的高级别墅区;另一种方案是结合原始地形建设阶梯状的森林别墅.在阐述场地工程地质条件的基础上,从建筑布局、方案设计、施工技术、经费预算4个方面进行了对比研究,结果表明第一种方案不适宜,结合原始地形建设阶梯状的森林别墅的第二种方案较为可行.
