东海富营养化封闭海水养殖海域浮游植物分布与控制因子

The distribution of phytoplankton and its correlation with environmental factors were studied monthly during August 2012 to July 2013 in the Yantian Bay. A total of 147 taxa of phytoplankton were identified, and the average abundance was in the range of 0.57×10~4 to 7.73×10~4 cell/L. A total of 19 species dominated the phytoplankton assemblages, and several species that are widely reported to be responsible for microalgae blooms were the absolutely dominant species, such as Skeletonema costatum, Navicula sp., Thalassionema nitzschioides,Pleurosigma sp., and Licmophora abbreviata. The monthly variabilities in phytoplankton abundance could be explained by water temperature, dissolved oxygen, salinity, dissolved inorganic nitrogen(DIN), and suspended solids. The results of a redundancy analysis showed that p H and nutrients, including DIN and silicate(SiO_4), were the most important environmental factors controlling phytoplankton assemblages in specific months. It was found that nutrients and pH levels that were mainly influenced by mariculture played a vital role in influencing the variation of phytoplankton assemblages in the Yantian Bay. Thus, a reduction of mariculture activities would be an effective way to control microalgae blooms in an enclosed and intensively eutrophic bay.     

黄海苏北浅滩海域春夏季浮游植物时空分布及其控制生态因子

The Subei Shoal is a special coastal area with complex physical oceanographic properties in the Yellow Sea. In the present study, the distribution of phytoplankton and its correlation with environmental factors were studied during spring and summer of 2012 in the Subei Shoal of the Yellow Sea. Phytoplankton species composition and abundance data were accomplished by Uterm?hl method. Diatoms represented the greatest cellular abundance during the study period. In spring, the phytoplankton cell abundance ranged from 1.59×10~3 to 269.78×10~3 cell/L with an average of 41.80×10~3 cell/L, and Skeletonema sp. and Paralia sulcata was the most dominant species. In summer, the average phytoplankton cell abundance was 72.59×10~3 cell/L with the range of 1.78×10~3 to 574.96×10~3 cell/L, and the main dominant species was Pseudo-nitzschia pungens, Skeletonema sp., Dactyliosolen fragilissima and Chaetoceros curvisetus. The results of a redundancy analysis(RDA) showed that turbidity,temperature, salinity, pH, dissolved oxygen(DO), the ratio of dissolved inorganic nitrogen to silicate and SiO_4-Si(DIN/SiO_4-Si) were the most important environmental factors controlling phytoplankton assemblages in spring or summer in the Subei Shoal of the Yellow Sea.     

近54年定西市降水趋势及突变分析

以定西市1956～2009年降水资料为基础,采用线性趋势、Mann-kendall、滑动t检验等方法,分析了定西市近54年降水的变化特征。结果表明:定西市年降水量存在减少趋势,平均递减率为11.7mm/10a;西部地区递减率最大,而北部地区的减少趋势最为明显;定西市年降水量系列1986年发生了显著突变,突变后均值相对减少了47.7mm;除中部地区外,其他各地区也发生了显著性突变,突变减少量在71.1～81.4mm之间,其中西部地区突变量最大;各地区的突变年份不相一致,东部和北部地区发生在1968年,南部地区发生在1993年,西部地区发生在1980年。     

陕西柞—山地区冷（水沟）—池（沟）—色（河铺）金钼铜矿带特征及其区域找矿意义

陕西柞—山地区冷(水沟)—池(沟)—色(河铺)金钼铜矿带地处陕西柞—山地区南部,位于小茅岭—陡岭元古宙岛链状隆起带中段,中、南秦岭接合部。该带东西长35.7 km,南北宽7.6 km,已在其中发现多处与燕山期中酸性岩浆活动有关的金钼铜矿床。对带内的冷水沟金铜矿床、池沟金钼铜矿床、色河铺铜矿等主要矿床的地质、矿体、蚀变、矿化规律进行了总结,发现矿化受主斑岩体控制,总体上,往往从斑岩体向围岩,出现内钼、外铜、远金的多金属矿化空间分带性,构成了斑岩型-矽卡岩型-隐爆角砾岩型-构造蚀变岩型金钼铜成矿系列。冷-池-色金钼铜矿带的发现,为中、南秦岭寻找斑岩型钼铜矿床提供了直接证据,拓宽了柞(水)—山(阳)地区的找矿思路和找矿空间。     

秦岭造山带北缘的斜向碰撞与汇聚因子

秦岭北缘洛南—栾川断裂带是华北板块南缘与秦岭造山带汇聚-拼合带,具有SW→NE向俯冲兼左旋走滑的性质,并构成叠瓦状构造和双重构造的组合样式。秦岭北缘不同性质的构造组成有规律的图案,其展布方位和运动学方式与板块汇聚的动力学特征极为吻合。变形分析结果表明,区内变形岩石主要是中上地壳的产物,岩石有限应变的三轴比为:X∶Y∶Z=8.86∶4.32∶1,应变椭球体为扁椭球状。汇聚因子是:在洛南地区板块汇聚方向为22°,汇聚方向与板块边界的夹角为73°;在栾川地区板块汇聚方向为31°,汇聚方向与板块边界的夹角为82°,显示出秦岭造山带与华北板块南缘的碰撞和拼合具有典型的斜向汇聚特征。     

发展河南工业旅游有关问题研究
