The ecosystem-based management of nearshore waters requires integrated assessment of ocean health and scientific guidance on artificial regulations to promote sustainable development. Quantitative approaches were developed in this paper to assess present and near-term ocean health based on ecosystem services. Results of the case study in the Laizhou Bay of China showed that the index score of ocean health was 0.785 6 out of 1.0 at present and was expected to range from 0.555 1 to 0.804 1 in the near-term future depending on different intensities of artificial regulation of negative pressures. Specifically, the results of ocean health at present mainly indicated that cultural services and provisioning services performed essentially perfectly while supporting services and regulating services functioned less well. It can be concluded that this nearshore ecosystem would partially lose supporting and regulating services in the near-term future if the increasing pressures were not wellregulated but that all of these categories of ecosystem services could be slightly improved if the negative pressures were fully controlled. Additionally, it is recommended that publicity and education on ecosystem services especially on cultural services and regulating services should be further strengthened. The analytical process and resulting quantification provide flexible tools to guide future development of regulations so as to facilitate ecosystem-based management in the coastal zone.

The predictability of marine ecosystem dynamics models is one of the most vital factors to limit their practical applications, of which the stability is the fundamental condition. In order to discuss the stability and Hopf bifurcation of marine ecosystem dynamics models, an approach based on a theorem termed dimension reduction was proposed and further applied in the mass-conservative nutrient-phytoplankton-zooplankton-detritus（NPZD） model in this paper. Results showed that the nonsingular equilibrium point of NPZD model was analytically stable in use of the dimension reduction theorem and the Hopf bifurcation might occur when model parameters changed along the threshold values. The analytical results of the NPZD model were further verified by numerical simulation in this study. It can be concluded that this approach based on the dimension reduction theorem is well applicable to the theoretical analysis of a kind of stability problems and Hopf bifurcation of massconservative systems.

Research on carrying capacity, aiming at maintaining the limited ability of the Earth＇s life supporting system to sustain human development, requires a comprehensive and ecosystem-based approach to monitor and assess the localized sustainability of coupled social and ecological systems. A definition termed the ecosystem-based carrying capacity of island（EBCCI） was developed in this paper of which the indices of fundamental and realized carrying capacities of island（FCCI and RCCI） were highlighted to emphasize the inter-dependencies between social systems and ecological systems. In order to avoid the difficulties and uncertainties of direct assessment, the related assessment model was established on the basis of synthetic evaluation of inherent and external factors affecting the EBCCI. The southern Miaodao Archipelago（SMA） located in the intersection of the Bohai Sea and the Yellow Sea, China, was taken as a typical example to acquire integrated recognition of the island ecosystem and its carrying capacity so as to discuss its sustainable development. The index scores of FCCI and RCCI in the SMA were 0.818 5 and 0.712 9 out of 1.0, respectively, with acceptable uncertainties. The results showed a relatively well capacity to sustain progress and relatively well realization of the carrying capacity of island ecosystem, owing to a well capacity of ecologically regulating, general performance of both ecologically supporting and resource provisioning, and a relatively high level of social supporting system. The study implied that it was critical to optimize the inter-dependencies and to sustain the relative balance between social systems and ecological systems so as to improve the RCCI and further facilitate the sustainability of SMA. The approach proposed in this paper provides a powerful tool which is well applicative to the regional level of an oceanic island or archipelago to study the sustainable development and can be further popularized to the coastal zone.

To study the water quality influenced by the anthropogenic activities and its impact on the phytoplankton diversity in the surface waters of Miaodao Archipelago, the spatiotemporal variations in phytoplankton communities and the environmental properties of the surface waters surrounding the Five Southern Islands of Miaodao Archipelago were investigated, based on seasonal field survey conducted from November 2012 to August 2013. During the survey, a total of 109 phytoplankton species from 3 groups were identified in the southern waters of Miaodao Archipelago, of which 77 were diatoms, 29 were dinoflagellates, and 3 were chrysophytes. Species number was higher in winter（73）, moderate in autumn（70）, but lower in summer（31） and spring（27）. The species richness index in autumn（5.92） and winter（4.28） was higher than that in summer（2.83） and spring（1.41）.The Shannon-Wiener diversity index was high in autumn（2.82）, followed by winter（1.99） and summer（1.92）, and low in spring（0.07）. The species evenness index in autumn（0.46） and summer（0.39） was higher than that in winter（0.32） and spring（0.02）. On the basis of principal component analysis（PCA） and redundancy analysis（RDA）, we found that dissolved inorganic nitrogen（DIN） and chemical oxygen demand（COD） in spring, COD in summer, p H in autumn, and salinity and oil pollutant in winter, respectively, showed the strongest association with the distribution of phytoplankton diversity. The spatial heterogeneity of the southern waters of Miaodao Archipelago was quite obvious, and three zones, i.e., northeastern, southwestern and inter-island water area, were identified by cluster analysis（CA） based on key environmental variables.

以2015年度全国百位优秀县委书记为样本,对县域主政官员的个体特征和行动策略对行动绩效的影响进行分析,可以为县域主政官员的遴选、考核、培育提供参考。研究结果显示:(1)优秀县委书记年龄与进取性正相关,这表明至少在县政层级,应设置主政官员更加宽幅的年龄任用和任职年限区间;(2)学历与官员的进取性正相关,交叉学科的思维优势并未显现,这表明既要选用高学历背景官员,又要根据所在区域政治、经济和社会情境对治理目标进行权重排序,进而选拔相适学科属性的官员;(3)籍贯与任职区域相同的县委书记,绩效表现优秀,异地任用尚需因人因地制宜;(4)拥有下乡经历的县委书记重视扶贫工作,政策执行力度较好,这表明应该继续推动机关干部下乡,并选拔有下乡经历的干部走上尚需强化脱贫效果、实现乡村振兴的县级领导岗位。

现代化是人类的共同事业,但现代化并非一个自然的社会演变过程,而是拥有复杂层次结构和因素变量的长历史演化过程。后发国家被西方“冲击”后的被动现代化“反应”,需遵循发展的政治经济学逻辑,即国家建构、政党领导和政府质量是促成自主现代化的基础要素。从国家建构看,后发国家自主现代化的前置问题是国权问题,国家认同持续注入则是国家建构的根本;从政党领导看,后发国家需要政党的自主现代化共识凝结和政治动员,且后发国家政党应以自身制度化带动国家政治制度化;从政府质量看,渐进经济改革的政策创制是政府质量高低的关键指标,公正、回应和廉洁则是政府质量的价值依归。中国式现代化的国家建构、政党领导和政府质量的目标分别指向国家人民属性和建设人民国家、以人民为中心的现代化新形态以及效能与公信力兼具的法治政府,它们是中国式现代化高度自主性的根本保障。后发国家现代化如果仅聚焦技术层面的工业化或硬性照搬照抄西方制度模式,未基于基本国情以渐进模式促成经济、政治和社会的相适改革演进,则必然遭遇挫折,沦为西方现代化的“附庸”。

改革开放以来,基于中央政府选择性试验模式下的渐进式体制变革,释放诸多发展元素的动能,有效促成了经济领域的巨大成就。经济特区作为渐进式体制转轨的活性载体,或者说中央政府改革政策选择的"试验田",发挥了不可或缺的导引作用。然而,近年来,经济特区治理困境逐步显现,表征多种多样,集中表现在政策、体制和功能三个层面。地方政府核心行动者动力衰竭是经济特区治理困境生成的内生性因素。基于心理契约违背模型,分析地方政府核心行动者动力衰竭的成因,表明了通过制度规引与愿景管理实现对地方政府核心行动者心理契约违背的防范的必要性。
