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.

Heat budget of the south-central equatorial Pacific in CMIP3 models

ABSTRACT Using data from 17 coupled models and nine sets of corresponding Atmospheric Model Intercomparison Project （AMIP） results, we investigated annual and seasonal variation biases in the upper 50 m of the south-central equatorial Pacific, with a focus on the double-ITCZ bias, and examined the causes for the amplitude biases by using heat budget analysis. The results showed that, in the research region, most of the models simulate SSTs that are higher than or similar to observed. The simulated seasonal phase is close to that observed, but the amplitudes of more than half of the model results are larger than or equal to observations. Heat budget analysis demonstrated that strong shortwave radiation in individual atmospheric models is the main factor that leads to high SST values and that weak southward cold advection is an important mechanism for maintaining a high SST. For seasonal circulation, large surface shortwave radiation amplitudes cause large SST amplitudes.     

Surface rainfall and cloud budgets associated with mei-yu torrential rainfall over eastern China during June 2011

Surface rainfall and cloud budgets associated with three heavy rainfall events that occurred over eastern China during the mei-yu season in June 2011 were analyzed using 2D cumulus ensemble model simulation data.Model domain mean rainfall showed three peaks in response to three prescribed ascending motion maxima,primarily through the mean moisture convergence during the torrential rainfall period.Prescribed ascending motion throughout the troposphere produced strong convective rainfall during the first （9 June） and third （17-18 June） rainfall events,whereas strong prescribed ascending motion in the mid and upper troposphere and weak subsidence near the surface generated equally important stratiform and convective rainfall during the second rainfall event （14 June）.The analysis of surface rainfall budgets reveals that convective rainfall was associated with atmospheric drying during the first event and moisture convergence during the third event.Both stratiform and convective rainfall responded primarily to moisture convergence during the second event.An analysis of grid data shows that the first and third mean rainfall maxima had smaller horizontal scales of the precipitation system than the second.     

黄坪上塘矿区水文地质条件及涌水量预测分析

结合贵州省黄坪县上塘矿区的水文地质条件特征,提出新的涌水量预算方法,预测得出：矿坑正常涌水量为2545m3／d,最大涌水量为99484m3／d,未来矿坑涌水量较大,对矿山开采有很大威胁。提出地表拦截和地下水抽排措施。     

万福矿井充水水源分析及矿井涌水量预计

通过对井田水文地质特征及矿井充水因素的分析,认为矿井的主要充水水源为3煤层顶底板砂岩裂隙含水层及三灰岩溶裂隙含水层。采用“大井法”对矿井涌水量进行了预算,确定矿井的正常涌水量为279 m3/h,预算结果为矿井的设计提供了科学依据。

美国地质调查局2013年工作重点变化及对我国地质工作的启示

美国地质调查局今年年初公布了其2013年财政预算拨款计划。预算拨款反映了其工作重点优先次序,根据预算拨款的增幅多少,美国地质调查局2013年工作重点先后顺序为:生态系统研究,自然灾害预防与研究,核心科学计划和气候与土地利用研究,能源、矿产与环境健康,水资源调查。当前,世界各国都非常注重地质工作与经济社会发展紧密结合,美国地质调查局的战略研究最具有代表性。我国地质工作,特别是自改革开放和中国地质调查局的成立以及新一轮国土资源大调查以来,得到了较快发展。根据我国国情,经济社会发展对矿产资源的需求明显增加,资源消耗开始进入高增长的爬坡阶段,除必须加强地质找矿,坚持开源与节流并举,国内国外两种资源并举外,保障经济社会可持续发展和社会和谐稳定,加强地质工作与经济社会发展紧密结合,加强生态系统研究和水资源保护及可持续利用研究,预防和防止自然灾害成为时代赋予地质科学工作者的新的历史使命。
