Distribution of Fine Roots in a Mixed Cunninghamia lanceolata-Tsoongiodendron odorum Plantation

对27年生混交比例为2行杉木和1行观光木的混交林和杉木纯林群落细根分布的研究表明,杉木和观光木行间的杉木细根密度虽比杉木与杉木行间的低8.5％,但观光木细根密度则高152.09％,其细根总密度比杉木与杉木行间的大10.43％。混交林中杉木各径级活细根密度呈单峰型分布,均以5-10cm土层最大,而观光木各径级活细根主要分布在0-10cm土层内。纯林杉木各径级活细根密度亦基本呈单峰型分布,但峰值出现在10-20cm或20-30cm土层。不同树种不同径级死细根的分布均与其各自的活细根分布相似。混交林中灌木细根密度在30-40cm的土层最大,而纯林中的灌木细根集中于0-10cm的表土层;混交林和纯林中的草本细根均集中在0-5cm土层。与纯林的相比,混交林中杉木细根主要分布的土层明显上移,表层土壤细根所占比重增大,有利于更好利用土壤养分和提高群落生产力。Fine roots were measured by soil core sampler in a mixed plantation of 27-year-old Cunninghamia lanceolata (C) and Tsoogiodeudron odorum (T) in Fujian Province. Fine root density of C at interrow between C and T was lower by 8.5% than that between C and C, but fine root denstiy of T and total fine root density were higher by 152.09% and 10.43%, respectively. High density of living fine roots with different thickness of C in mixed plantation appeared at 5-10 cm soil depth, whereas that of T at 0-10 cm. Compared to mixed plantation, living fine root density in pure C plantation appeared at 10 -30 cm of soil depth. The distribution of dead fine roots had the same pattern. In mixed plantation, upward trend of soil layer with maximum fine roots of C was obvious, showing that mixed plantation had an advantage over pure plantation in nutrient absorption.中国博士后科研基金项目（1999-10）;;福建省科委重大基础研究项目（2000-F-004）;; 高等学校骨干教师资助计划项目;;福建省自然科学基金项目（B0110025

NUTRIENT CYCLING OF N AND P BY A MIXED FOREST OF CUNNINGHAMIA LANCEOLATA AND TSOONGIODENDRON ODORUM IN SUBTROPICAL CHINA

通过对福建三明 2 7年生杉木 (Cunninghamialanceolata) 观光木 (Tsoongiodendronodorum)混交林 (混交比例2 :1)及杉木纯林群落N、P养分循环进行为期 2年的研究。结果表明 ,混交林中杉木和观光木地上各组分的N、P含量大小均为叶 >活枝 (或皮 ) >枯枝 >干 ,而根系的则随径级的减小而增大 ,且观光木各组分的N含量均高于杉木的 ;混交林群落的N、P总积累量达 5 85 .2 2 3kg·hm-2 和 12 8.784kg·hm-2 ,分别是纯林群落的 1.5倍和 1.3倍。混交林群落N、P养分年归还量达 75 .740kg·hm-2 和 5 .493kg·hm-2 ,分别是杉木纯林的 113 .0 %和 79.6 %。混交林通过凋落物、降水淋溶和细根枯死 3种途径的N归还量分别占群落总归还量的 6 7.1%、8.4%和 2 4.5 % ,而纯林的则分别为 6 9.3 %、8.1%和 2 2 .6 % ;混交林 3种途径的P归还量分别占群落总归还量的 6 4.0 %、7.5 %和 2 8.5 % ;而纯林则为 74.8%、5 .3%和 19.9%。混交林中林下植被层的N、P归还量分别占群落总归还量的 14.8%和 37.3 % ;而纯林的则为 2 9.5 %和 5 9.4%。混交林群落的N、P富集率和利用系数均低于纯林的 ,而周转期则均大于纯林的。混交林群落的P吸收系数小于纯林的 ,而循环系数则高于纯林的 ,但其两者的N吸收系数和循环系数则相似。A study on the cycling of N and P in a pure forest of Chinese fir ( Cunninghamia lanceolata (Lamb.) Hook. and a Chinese fir_ Tsoongiodendron odorum Chun mixed forest (2 Chinese fir: 1 T. odorum ) over two years was carried out in Sanming, Fujian, China. For both Chinese fir and Tsoongiodendron odorum, the concentrations of N and P in aboveground fractions were in the order of leaves>living branches (or stem bark)>dead branches> stem wood, and those in roots increased with an increase in root diameter. N concentrations in various fractions of T. odorum were higher than their respective values for Chinese fir. The standing crops of N and P in the mixed stand were up to 585.223 kg·hm -2 and 128.784 kg·hm -2 , being 1.5 and 1.3 times as much as that in the pure stand, respectively. The annual return of N and P amounted to 75.740 and 5.493 kg·hm -2 in the mixed forest, respectively, being 113.0% and 79.6% of that in the pure forest. The fractions of annual N return through litterfall, rain leaching and fine root turnover were 67.1%, 8.4% and 24.5% in the mixed forest, respectively, and the corresponding values were 69.3%, 8.1% and 22.6% in the pure forest. These three pathways contributed to 64.0%, 7.5% and 28.5% of total P return in the mixed forest, and 74.8%, 5.3% and 19.9% in the pure forest, respectively. 14.8% of N return and 37.3% of P return in the mixed forest, and 29.5% of N return and 59.4% of P return in the pure forest were derived from the undergrowth vegetation. For both N and P elements, the enrichment ratios and the utilization coefficients were lower, and the recycling periods were higher in mixed forest than in pure stand. For P, the absorption coefficient was lower, and the cycling coefficient was higher, in mixed forest than in pure forest, while there were no significant differences for those of N between the two forests.中国博士后科研基金;; 福建省科委重大基础研究项目 ( 2 0 0 0_F_0 0 4);; 高等学校骨干教师资助计划项

Electrodeposition of Active Platinum on Stainless Steel

采用低毒、较缓和条件下预处理不锈钢基底 ,在电沉积过程中引入超声波振荡技术 ,并筛选出最佳电流密度组合进行电沉积 ,制备出与基底粘结牢固、析氢电催化性能高的不锈钢镀铂电极。从电极的双层电容值可推出电极活性的改善主要归因于表面粗糙度的增加。The substrate of stainless steel was pretreated under low toxic and moderate conditions. Ultrasonic agitation technology was employed in the process of electodeposition. In addition, the optimal combination of current densities was selected. As a result, platinum plated stainless steel electrode which not only was adherent to the substrate but also possessed excellent electrocatalyticproperty for HER was prepared. It can be deduced from the measured values of the double layer capacity of the electrode that the improvement of the electrode activity was mainly due to the increase in surface roughness of the electrode.厦门大学固体表面物理化学国家重点实验室资助!课题 ( 950 1

Linking Watershed Nutrient Loads and Riverine Export to Reservoir Eutrophication:The Case of Shanzai Reservoir, Fujian Province

建立流域氮磷输出、河流输送与入库通量的分析方法,以福建省山仔水库为例,基于gIS技术分析乡镇、子流域的氮磷污染分布和来源构成,识别关键源区并探讨库区水质与流域污染输出和河流输送之间的关联性。结果表明,2009年山仔流域单位面积总氮输出负荷为13.4 kg n·HM-2·A-1(生活污水和化肥流失占64%),总磷输出负荷为0.82 kg P·HM-2·A-1(畜禽养殖和生活污水占90%),入库氮、磷负荷分别为3248 T n·A-1和192 T P·A-1,其中河流输入占62%和89%,环库区面源污染贡献小于2%;不同乡镇单位面积氮输出负荷为3.54~20.0 kg n·HM-2,磷输出负荷为0.38~2.50 kg P·HM-2,其中日溪乡和霍口乡临近库区,化肥流失与畜禽养殖污染最重。上游乡镇污染较轻,但生活污水比重大(42%~84%)。皇帝洞溪子流域污染最重(19.4 kg n·HM-2;1.95 kg P·HM-2),其次是霍口溪中下游和日溪子流域。库区总氮高值出现在坝区和日溪湾汊,总磷高值在小沧至霍口溪七里入口之间,水质有明显分区,与流域污染分布、河流输送和库区沉积物的释放相关联,河流输入对库区富营养化起决定性作用。流域氮磷输出负荷比值平均为16,库区水中氮磷比值在15~20之间,意味着该生态系统处于磷的弱限制,水华爆发风险较大,建议采取“分区整治流域污染、氮磷联合削减、畜禽养殖和磷肥流失优先控制“的富营养化防控策略。A quantitative analysis of watershed nitrogen(N)and phosphorus(P)loads,riverine export and other inputs to reservoir was conducted for Shanzai reservoir in Fujian Province.Spatial variation of N and P pollution and major components were interpreted at town and sub-watershed scale using GIS techniques,and the critical source area(CSA)was indentified.The linkage between reservoir water quality and watershed nutrients loading and riverine export fluxes was examined.Results revealed that total N and P loads per unit area of the Shan zai watershed were 13.4 kg N·hm-2·a-1and 0.82 kg P·hm-2·a-1,respectively.Domestic sewage and fertilizer runoff accounted for 64% of total N load,and livestock waste and domestic sewage shared 90% of total P load.Total N and P loads to the Shanzai reservoir were 3248 t N·a-1 and 192 t P·a-1,62% and 89% of which were through riverine transport and the remainder mostly from sediment release.Less than 2% of in puts were from non-point sources in the surrounding area.Town-level N and P loads per unit area ranged from 3.54~20.0 kg N·hm-2and 0.38~2.50 kg P·hm-2,respectively.Two towns(Rixi and Huokou) adjacent to the reservoir were identified as CSA of fertilizer runoff and livestock waste,while human sewage dominated the nutrient load(42%~84% of total)in other towns in the upstream area.Huangdidong subwatershed was the most polluted catchment(19.4 kg N·hm-2;1.95 kg P·hm-2),followed by the lower reaches of Huokou River and Rixi subwatershed.The high value of total N concentration was observed near the dam head and Rixi inlet,whereas high total P concentration was found in channel from Huokuo inlet to Xiaocang.The spatial variation of the nutrients level in the reservoir was highly associated with watershed nutrient loads,riverine export and sediment-water exchange,indicating that riverine input is the decisive factor contributing to eutrophication of the reservoir.The average N∶P ratio of the nutrient load was calculated as 16 for the whole watershed,which combined with the TN∶ TP ratio of 15~20 observed in reservoir surface water suggested that the reservoir ecosystem was weakly limited by P and tended to stimulate algal bloom.To mitigate eutrophication,reduction of both N and P pollution should be considered in those CSAs,with a priority given to P pollution from livestock and phosphate fertilizer loss.公益类科研院所专项(2011R1004-2); 中央高校基本科研业务费专项(厦门大学基础创新科研基金项目)(2012121053

Some silvicultural measures, such as planting pure stands, clear cutting and slash burning, have been widely applied during this conversion. Yield decline and land deterioration in such disturbed ecosystem has become serious. In this context, the ecological comparisons between native forests and monoculture plantations are necessary in providing the implications for sustainable management. Few studies on fine roots dynamics have been conducted within these ecosystems though the importance of fine roots in carbon and nutrient cycling has been increasingly emphasized due to their rapid turnover rates. Two 33 year old plantations, Chinese fir (Cunninghamia lanceolata, CF) and Castanopsis kawakamii (CK), were chosen to examine fine root (005). An early spring flush of root biomass (March) was found in these three forests, and the minimum value mainly occurred during May July or November January. For the NF, 598% of root biomass was found in the top soil of 0～10 cm, a layer that maximum depth distribution difference among these forests occurred, where root biomass of the NF was 237 times and 812 times as much as that of the CK and the CF, respectively. Percentages of original mass lost during the first year of decomposition ranged from 4379%～5631% for the FH to 6834%～8013% for the NF Mean annual root decomposition, mortality and production ranged from 847 t/(hm 2·a), 8632 t/(hm 2·a) and 95 t/(hm 2·a) in the NF to 2503 t/(hm 2·a), 2492 t/(hm 2·a) and 2513 t/(hm 2·a) in the CF. The mean root turnover rate ranged from 178 times/a in the NF to 169 times/a in the CF.国家自然科学基金资助项目(30170770);福建省自然科学基金资助项目(B0110025);高等学校优秀青年教师教学科研奖励计划资助项目;福建省基础研究重大资助项目(2000-F-004

However, how phagosomes transmit signals to recruit mitochondria has remained unclear. Here we found that the kinases Mst1 and Mst2 functioned to control ROS production by regulating mitochondrial trafficking and mitochondrion-phagosome juxtaposition. Mst1 and Mst2 activated the GTPase Rac to promote Toll-like receptor (TLR)-triggered assembly of the TRAF6-ECSIT complex that is required for the recruitment of mitochondria to phagosomes. Inactive forms of Rac, including the human Rac2D57N mutant, disrupted the TRAF6-ECSIT complex by sequestering TRAF6 and substantially diminished ROS production and enhanced susceptibility to bacterial infection. Our findings demonstrate that the TLR-Mst1-Mst2-Rac signaling axis is critical for effective phagosome-mitochondrion function and bactericidal activity.Supported by the National Basic Research Program (973) of China (2015CB910502 to L.C.), China's 1000 Young Talents Program (D.Z. and L.C.), the 111 Projects (B12001 and B06016), the Fundamental Research Funds for the Central Universities of China-Xiamen University (CXB2014004 to J.Z.; 20720140551 to L.C.; and 2013121034 and 20720140537 to D.Z.), the National Natural Science Foundation of China (31270918, 81222030 and J1310027 to D.Z.; 81372617, 81422018 and U1405225 to L.C.; 81472229 to L.H.; and 81302529 to X.L.), the Natural Science Foundation of Fujian (2013J06011 to D.Z. and 2014D007 to X.L.), the US National Institutes of Health (RO1 CA136567 for J.A.) and institutional funds from Massachusetts General Hospital (for J.A.).
