The application of human induced oxygen consumption and carbon emission theory in urban region was summed up and on this base a new model of urban carbon and oxygen balance (UCOB) was constructed by calculating the carbon and oxygen fluxes. The purpose was to highlight the role of vegetation in urban ecosystems and evaluate the effects of various human activities on urban annual oxygen consumption and carbon emission. Hopefully,the model would be helpful in theory to keep the regional balance of carbon and oxygen,and provide guidance and support for urban vegetation planning in the future. To test the UCOB model,the Jimei District of Xiamen City,Fujian Province,China,a very typical urban region,was selected as a case study. The results turn out that Jimei′s vegetation service in oxygen emission and carbon sequestration could not meet the demand of the urban population,and more than 31.49 times of vegetation area should be added to meet the whole oxygen consumption in Jimei while 9.60 times of vegetation area are needed to meet the carbon sequestration targets. The results show that the new UCOB model is of a great potential to be applied to quantitative planning of urban vegetation and regional eco-compensation mechanisms.

^137Cs nuclear tracing technique was used to estimate rates of soil redistribution on a sloping field with traditional erosion control measures located near Shangqiao Village, Neijiang City, in the Sichuan Hilly Basin of China. The downslope changes of ^137 Cs inventory and its corresponding soil erosion rates in the sloping field show a rolling trend and have two peak values in two inflexions of the sloping field, these result reflects that the changes of microphysiognomy play a key role on the spatial soil redistribution of the sloping field.

Background Several million subclavian-vein catheters are placed in patients each year to enable caregivers to administer chemotherapy, total parenteral nutrition, or long-term antibiotics or to manage preoperative fluids. Subclavian venipuncture requires the position of a deep vein to be identified with only surface landmarks. But the traditional right subclavian vein (RSV) catheterization (primitive procedures) is not the answer for all patients. The precise location of the vein is not known, and it is important to select the most appropriate method to achieve central venous access safely in any given patient. To modify the primitive procedures of the RSV catheterization for greater success and reduce the complications, anatomic studies and ultrasonography were conducted and clinical applications were validated. Methods Anatomical observation and measurement of the RSV and its adjacent structures were performed on 20 adult cadavers according to modified procedures. The RSV catheterization of 2900 cases was carried out by the modified procedure, 500 of these cases were observed by ultrasonography after the operation. Results The anatomical studies and clinical application showed that the insertion point differs from the bodily form of fatness or leptosome. The clinical data revealed that in the 2900 cases which were performed with the modified approach, the success rate was 98.90% (2868 cases), the failure rate was 1.10% (32 cases), and the complication rate is 0.79% (23 cases), and the catheterization time is (31.2±10.5) minutes. Five hundred and sixty cases of the RSV catheterization were carried out by the recommended insertion procedure; the results were compared with the modified approach and the traditional approach. The successful rate of the traditional approach was 73.0%, of which the complication rate was 6.1%; the two approaches were significantly different (successful rate: χ 2=626.642, P <0.01; complication rate: χ 2=80.708, P <0.01).

改革开放以来我国的城市化率急速提高,城市住区形态变迁呈现出大规模、翻新频率快和多样化的特点。研究不同城市住区形态变迁前后的代谢效率变化,对我国的可持续人居环境构建有着重大的意义。运用功能分类法设计了城市代谢系统分类框架作为构建城市代谢系统动力学模型的基础,继而通过对住区与住区形态的文献调研与形态分析,将典型住区类型分为旧式住区、传统单位住区、普通商品房住区、新式商品房住区与半城市化住区。选择厦门市为研究区域,采用调查问卷进行了数据收集,并用能值分析法计算出不同住区类型的代谢效率,随后用Vensim软件构建了住区形态变迁对城市代谢效率影响的系统动力学模型。通过情景模拟后发现:住区形态的更迭过程基本上都会带来福利效率的提升,但在很多情况下会给城市整体物质代谢效率带来负面影响,交通效率与住房效率的下滑是最主要的原因。旧式住区向半城市化住区转变是仅有一个城市整体物质代谢效率提高的情景。半城市化住区和普通商品房住区向新式商品房住区转变的情景下,城市整体物质代谢效率的下降幅度与福利效率的增长幅度都较为适中。

城市公园主要由水体和绿色植被等景观构成,其形成的公园冷岛(Park cool island,PCI)已成为减缓城市热岛效应的重要途径之一。采用景感生态学中的景感营造理念规划设计城市公园或优化公园空间结构有助于增强公园冷岛效应,进一步改善局地城市热环境。选择沿海城市——厦门市为研究对象,基于2013年8月的Landsat-8 OLI/TIRS遥感影像和Google Earth高分影像数据,首先提取了研究区15个公园的土地利用信息,采用改进的地表温度单通道算法,获取了城市公园地表温度数据,并采用缓冲区分析、景观格局指数和多元统计等方法定量分析公园内部平均地表温度、城市公园冷岛强度(即降温幅度)、公园冷岛影响距离(即对周边区域的降温范围)三者的主要影响因子,并利用景感生态学原理初步剖析了城市公园景感营造的原则。结果显示:(1)公园面积和公园建设用地面积是影响公园平均温度的关键因子(R^(2)=0.915),这两个因子与公园平均温度均呈显著非线性相关;公园面积存在阈值55 hm^(2)左右;(2)公园冷岛PCI强度由公园绿地面积、公园建筑面积和面积-周长形状指数(P/A)三个因子决定(R^(2)=0.911);公园冷岛PCI强度与公园绿地面积呈显著非线性正相关,与公园建筑面积呈显著非线性负相关,与面积-周长形状指数(P/A)呈显著线性负相关;在确保公园绿地面积达到一定阈值时,应该尽量降低公园建筑面积,增加公园形状复杂度,有利于其PCI强度的增加,缓解城市热岛效应;(3)公园冷岛影响距离由公园面积和公园水体面积比例决定(R^(2)=0.719),公园冷岛影响距离与两者呈显著正相关;绿地公园中提高公园水体的面积比例,有助于增大公园冷岛的影响距离;(4)城市公园的规划与设计,需要运用景感生态学的原理,从缓解城市热岛效应的角度,充分考虑公园大小、形状、土地利用类型组成比例及空间配置等因素。

针对关于不透水面时空演变研究还缺乏有效的定量方法的问题,以厦门市为研究区,引入不透水面变化轨迹、不透水面重心及其迁移路径,定量剖析不透水面时空演变过程。结果表明,研究时段内不透水面持续扩张,研究区21%和35.32%的面积最终分别转化为高覆盖和中覆盖不透水面类型。转化为高覆盖类型的轨迹分布在各个行政区的建成区及其周边,另外3种类型的变化轨迹以圈层结构的形式,随着时间的推进在空间上不断远离原城区。20年来厦门本岛不透水面重心稳定在湖里区与思明区的交界地带,受岛内用地条件和自然条件的限制,重心迁移距离较小,岛外4个区不透水面重心迁移距离大于厦门岛,尤其是集美区4个时段内的迁移距离均较大。
