The Study of Urban Residents’ Life Quality in the Perspective of Community Capacity ----Based on the Investigation of Shenzhen and Xiamen City

城市居民生活质量直接关系到每个城市居民的切身利益,是人类社会最关心的话题之一，随着我国国民经济和社会的快速发展,提高城市居民生活质量已成为各级政府确定可持续发展目标和制定基本政策的重要依据和组成部分，因此对问题进行深入系统的研究具有非常重要的意义。 目前，国内外学者对城市居民生活质量研究较多，对城市社区能力建设的研究也在逐渐增多，但是这两个社会学理论之间的直接对话几乎没有。于是，本研究调查了深圳市和厦门市共21个社区居民基本生活状况与所在社区状况,应用社会学中的生活质量理论与社区能力建设理论,构建生活质量指标体系与社区能力指标体系，对城市居民生活质量与城市社区能力进行描述、评价以及居民主观生...The quality of life of urban residents is directly related to their vital interests of each residents living in the city, which of also one of the hot topics in human society.

Reserch on Classification Framework of Public Service

公共服务分类，就是根据公共服务的共同点和差异点，采用一定的标准和方法，依据一定的原则，对公共服务进行全面、系统的划分与归类。公共服务分类不仅是一个理论问题，也是一个实践问题。科学的公共服务分类，有利于政府职能的准确定位，有利于政府在一定历史阶段内实现对公共服务的分类发展。 公共服务分类是一个世界性的难题。为了回应社会的变化以及多样化的公共服务需求，这就要求公共服务分类能够反映出这些变化。因此，从这一角度说，公共服务分类并非一劳永逸，而是处在动态发展之中的。研究这一不断变化的问题，使之更好地反映政府职能变化及促进公共服务型政府建设，具有重要的意义。 全文共由五个部分组成： 第一部分为引言，...Public Service classification is to conduct a comprehensive and systemtic division and classification about public service based on the common and difference of public service by adopting certain standards and methods and referring to some principles.

Prevention of barnacles on planted Rhizophora stylosa Griff seedlings with pesticide malathion and related eco-physiological effects

设置4种施药频度(3、7、14和28d)和马拉硫磷4种浓度(分别为原农药浓度45%的1/200、1/400、1/600和1/800)处理,在初植红海榄(Rhizophora stylosa Griff)幼苗上开展了1年防治藤壶试验。结果表明:随施药浓度和频度提高,处理组幼苗上藤壶生物量显著降低,且所有处理组均显著低于对照组(P<0.001);红海榄茎生物量和高度对施药浓度和频度不表现规律性反应;同一浓度的28d频度处理组幼苗的叶和根生物量及叶面积均低于其他频度处理组;在同一浓度下,施药频度越高叶数保持越多;3、7和14d频度处理组幼苗死亡率均较低,仅0~5%,28d频度处理组死亡率较高,为11%~22%,但对照组死亡率达39%;幼苗死亡率与藤壶生物量之间存在显著正相关关系(P<0.001),与叶生物量、叶数、根生物量及新生器官生物量存在显著负相关关系(P<0.001),与茎高、茎生物量、原繁殖体生物量等相关性不显著;施用农药造成红海榄幼苗叶绿素总量降低,Chl(a/b)比值上升,同时抗氧化酶系SOD和POD活性增大。建议在平均海平面高程的滩涂上造林,可采用频度14d、浓度1/800马拉硫磷喷雾防治藤壶。A one-year experiment on the prevention of the barnacles on planted Rhizophora stylosa Griff seedlings with malathion was conducted at Yingluo bay of Guangxi, China. Four pesticide concentrations (1/200, 1/400, 1/600, and 1/800 seawater solution of the original malathion concentration (45%)) and four spraying frequencies (every 3, 7, 14, and 28 days) were installed. The results showed that with increasing pesticide concentration and spraying frequency, the barnacle biomass on the seedlings decreased significantly, and all the treatments had a significantly lower barnacle biomass than the control (P<0.001). The seedlings stem biomass and height did not have definite patterns of responses to the pesticide concentration and spraying frequency. At the same pesticide concentration, spraying it every 28 days gave the lowest root biomass, leaf biomass and leaf area, and the more the spraying frequency, the more the leaves preserved. Also at the same pesticide concentration, spraying it every 28 days gave the highest mortality (11%-22%) of the seedlings, while spraying every 3, 7 and 14 days only gave 0-5% of the mortality. However, the mortality in control group reached 39%. Statistical analysis indicated that the seedlings mortality had a significant positive correlation with barnacle biomass (P<0.001), significant negative correlations with leaf biomass, leaf number, root biomass, and neonatal biomass (P<0.001), but no significant correlations with seedlings stem height, stem biomass, and remained propagule biomass. Spraying malathion decreased the seedlings leaf chlorophyll content, but increased the leaf Chl (a/b) ratios and SOD and POD activities. It was proposed that in case of mangrove forestation on tidal flats at mean sea level, spraying malathion at the concentration of 1/800 and with a frequency of every 14 days could prevent barnacle effectively.国家自然科学基金项目(30670317);; 厦门大学“新世纪优秀人才支持计划”项目(X07115);; 广西科学基金项目(0640014);; 北海市科技攻关资助项目(200601057

Conclusion: SLBZP can more; effectively adjust the expression of apoptosis related proteins of tumor; in mice with H22 hepatocellular carcinoma cells, and promoting tumor; apoptosis may be one of the possible mechanisms of SLBZP to improve; chemotherapy in treating hepatic cancer.国家自然科学青年基金项目; 福建省自然科学基金项目; 福建省大学生创新创业训练项

Phytoplankton biomarkers in surface seawater from the northern South China Sea in summer 2009 and their potential as indicators of biomass/community structure

生物标志物已被广泛应用于重建浮游植物生产力和群落结构变化。该方法假设之一是生标的含量可以反映表层海水的浮游植物生物量,但这个假设还缺乏现场观测的充分验证。对2009年冬季南海北部表层海水颗粒物中主要生标做了分析,利用其含量及比值研究浮游植物的生物量及群落结构的分布。生标含量表明硅藻、甲藻、颗石藻的高值区位于珠江口南部及广东沿岸,在陆坡区也有高值。生标比值显示硅藻在3个类群中的相对比例最高。其中,甲藻/硅藻比值高值区位于陆坡区,这与大洋水(黑潮)的入侵,带来大量暖水性甲藻有很大关系;颗石藻/硅藻比值总体趋势与生物量的分布相反,在近岸少数站位有高值,向外海逐渐增加,主要是因为颗石藻更适于寡营养盐的环境。生标结果所指示的生物量及群落结构的空间分布与前人的调查结果类似,为利用生标重建此区域的浮游植物生产力和群落结构变化提供了依据。Biomarkers have been widely used to reconstruct phytoplankton productivity based on the assumption that biomarker contents could reflect phytoplankton productivity in the surface seawater.However,this hypothesis has not been validated with modern survey.In this study,the contents and ratios of three phytoplankton biomarkers in the surface seawater of the northern South China Sea in winter 2009 were analyzed,to indicate spatial distributions of phytoplankton biomass and community structure.The results show high values for diatoms,dinoflagellates and coccolithophorids near the Pearl River Estuary and Guangdong coastal areas.The community structure indicates diatoms are the dominant phytoplankton species in winter.High values of dinoflagellate/diatom ratio occur near the slope area owing to intrusion of the Kuroshio,which favors the growth of dinoflagellates.The coccolithophorid/diatom ratio displays an increasing trend from the Pearl River Estuary to offshore region due to the advantage of coccolithophorids in oligotrophic environment,which is opposite to the productivity pattern of all biomarkers.These results are consistent with previous studies using phytoplankton cell and pigments,which provides support for the use of biomarker to reconstruct phytoplankton productivity and community structure in the SCS.国家重点基础研究发展计划项目(2007CB815934、2009CB421201);国家自然科学基金项目(40776029
