    水库是福建重要的水资源.通过2013-2015年遥感影像结合Google Earth和天地图提取福建水库3353座,分布在81个县区,总面积647.51 km2,约占全省土地面积的0.5%;其中面积≤1 km2水库3248座,总面积197.16 km2,面积>1 km2水库105座,总面积450.35 km2.基于经验公式估算总蓄水量188.18亿m3,其中小型水库3078座(91.80%),蓄水总量37.06亿m3(19.69%),大中型水库275座(8.20%),蓄水总量151.12亿m3(80.31%).从空间分布格局来看,福建水库水资源空间分布不均,沿海六市水库密度大于三个内陆市,大中型水库主要分布于福建西北部,蓄水量呈现西北多、东南少的特点.单位陆地面积水库数量沿海城市县区均多于内陆,而单位人口水库数量则相反;单位面积水库蓄水量沿海与内陆差异不大,而人均蓄水量则沿海大部分县区远小于内陆.仅以水库作为供水水源,不能满足沿海地区用水,但内陆地区供水充足.水库蓄水对河流水体的平均滞留时间为0.053~0.341 a,除晋江流域受水库蓄水强烈影响外,其他流域受水库中等程度影响.国家自然科学基金项目(31370471);;福建省杰出青年科学基金项目(2012J06009)联合资

    随着社会经济的发展,我国房地产业蒸蒸日上,已成为国民经济的支柱产业之一。而房地产业的健康发展,离不开国家宏观政策的干预和规范,在诸多宏观调控手段中,税收是最普遍的手段之一。近年来,我国房地产快速发展,房地产业经营利润大大提高,为规范房地产增值收益分配,增加国家财政收入,1994年,土地增值税应运而生,这是我国第一次对土地增值收益课税。土地增值税以转让房地产取得的增值额为征税对象,征税面广,其有效征收有利于增强国家对房地产市场的调控力度,控制土地炒买炒卖行为,保障国家土地合法权益。2000年以来,我国房地产市场以前所未有的高速度发展,存在投资过热的现象,为防止房地产泡沫被吹大,我国开展了新一轮房...With the social and economic development China's booming real estate industry has become a pillar industry of national economy.

    内容摘要 电子商务的应用给全球经贸注入了新的活力。频繁的跨国界、跨地区交易引起了大量跨国界、跨地区的民商事纠纷。而电子商务纠纷所具有的“无国界”等特性对传统的纠纷解决方式诉讼提出了严峻的挑战,当事人利用诉讼解决争议在管辖权、法律适用、判决承认和执行等诸多方面均遇到了难以克服的困难。在这种情况下,一种适应快捷高效的电子商务之需的替代性争端解决方式“在线纠纷解决机制”(OnlineDisputeResolution,简称ODR)应运而生。电子商务在中国正处于快速发展阶段,相应的在线纠纷也随之增多,如何及时解决这些纠纷以保障我国电子商务的健康快速发展,成为我国电子商务发展的当务之急。本文就OD...ABSTRACT The application of Electronic Commerce injects some new life into global economic and trade.

    酵母菌既具有细菌单细胞、生长快、能形成很好的絮体、适应于各种不同的反应器等特点,又具有真菌细胞大、代谢旺盛,耐酸、耐高渗透压、耐高浓度的有机底物等特性,因而可用于多类难处理有机废水的处理,并且具有处理效率高、污泥负荷高、占地面积小、剩余污泥可回收用作饲料蛋白等特殊的优越性。酵母菌废水处理技术有望成为常规好氧和厌氧处理技术的重要补充而在工业废水治理中发挥重要作用。Yeast cells have both the virtues of bacteria (living in single cell, growing fast, forming good flocs and suitable for various bioreactors) and fungi (high tolerance to acids, high salt and high concentration of substrates). When used in wastewater treatment, the yeast technology permits a high COD load and a small bioreactor and could endure various bad wastewater environments such as acid, high osmotic pressures and so on. Its residual sludge normally contains high protein and can be used as good additives in animal food. So this technology is expected to be a promising supplement for traditional aerobic and anaerobic wastewater treatment techniques to solve some intractable problems in industrial pollution.国家自然科学基金资助项目(50278095

    目的应用氢谱核磁共振代谢组学(1H-nMr)方法研究2型糖尿病(T2dM)合并脑梗死患者血清中小分子代谢物代谢轮廓的变化,探讨2型糖尿病合并脑梗死的可能发病机制。方法选择T2dM合并脑梗死患者19例、单纯T2dM患者25例及健康对照者29例,利用1H-nMr方法检测血清的代谢轮廓,通过偏最小二乘判别分析方法,鉴别各组别间血清小分子代谢物的区别。结果从血清偏最小二乘判别分析得分图中可以区分3组患者,与T2dM合并脑梗死有关的特征代谢物包括极低密度脂蛋白、低密度脂蛋白、葡萄糖、乳酸、丙酮酸、3-羟基丁酸、n-乙酰糖蛋白、亮氨酸、缬氨酸、前列腺素d2、前列腺素E2、同型半胱氨酸、氧化三甲胺、甜菜碱等。结论脂类代谢、糖代谢、氨基酸代谢的紊乱可能在T2dM合并脑梗死的发病中起到重要作用。炎症因子、同型半胱氨酸的增加,肠道菌群失调引起的氧化三甲胺、甜菜碱的浓度改变可能也与T2dM合并脑梗死的发生有一定关系。Aim To investigate the possible mechanism of cerebral infarction in type 2 diabetes mellitus(T2DM) through identifying the changes of metabolic products in serum by applying the method of 1H-nuclear magnetic resonance(1H-NMR).Methods Nineteen patients with cerebral infarction complication in T2DM,25 T2DM patients without cerebral infarction and 29 healthy controls were included in our study.The micromolecular substances of each participant in serum were detected by 1H-NMR.The metabolic profile of each participant was obtained.The partial least square discriminant analysis(PLS-DA) was used to examine the difference of metabolic profile among groups.Results Based on the analysis of score plots of groups,the T2DM patients with cerebral infarction,T2DM patients without cerebral infarction and the group of healthy controls were clearly distinguished by applying PLS-DA.The characteristic metabolic products of patients with cerebral infarction complication in T2DM included very low density lipoprotein(VLDL),low density lipoprotein(LDL),glucose,3-hydroxy butanoic acid,lactate,pyruvic acid,glycoprotein,leucine,valine,prostaglandin D2,E2,homocysteine,trimethylamine oxide(TMAO) and betaine.Conclusions The results of our study suggested that the metabolic disorders of lipids,carbohydrate and amino acid may play essential role in the development of T2DM with cerebral infarction.The elevated level of prostaglandin D2,E2 and homocysteine might play a role in the occurrence of cerebral infarction in T2DM.The change of TMAO and betaine which were caused by enteric dysbacteriosis,also might be related to the occurrence of cerebral infarction in type 2 diabetes mellitus
