语言的生态失衡及其对策

全球经济一体化加快的步伐使得主体语言逐渐取代少数语种，威胁着少数语种的存在与发展，造成了语言的生态失衡。因此，需要在全球范围内进行合理的语言规划，维持和保护少数语种。     

土地开发决策模式与城镇发展——近代英国海滨休闲城镇的启示

近代英国海滨休闲城镇的发展在很大程度上受到土地开发模式的影响和制约 ,不同时期的决策主体 (地主、“改善委员会”和市政当局等 )对土地开发的自发或自觉的决策 ,显示了他们把握机遇的准确程度 ,从而决定了海滨休闲城镇的发展趋向 :起初处于“自发”状态 ;铁路时代则以利用大片土地进行铁路与车站建设为关键 ;后期 ,市政府能否顺应时代、积极有效地介入城镇建设至关重要。有鉴于此 ,在我国城市化过程中应注意城镇土地开发 ,进行系统规划 ,避免无序开发 ,尤其不能听任开发商的“自发”行为 ,这样才能在我国建成一批功能各异、各具特色的生态城镇

The State, Institutional Transition and the Creation of New Urban Poverty in China

Since the 1990s, the introduction of a market economy and the process of rapid urbanization have been accompanied by a new urban poverty related to lay‐offs and unemployment as well as by large‐scale rural–urban migration, which is different from the traditional urban poverty of the ‘Three Nos’ (no relatives or dependants, no working capacity and no source of income). This article focuses on new urban poverty in China under market transition and discusses the causes of poverty creation. Instead of considering Chinese new urban poverty only as a result of market mechanisms, it argues that the state as the manipulator of institutions and policies does matter in the creation of new urban poverty, and that the cleavages between the old and new institutions further intensify it. Specifically, the following aspects of the creation of new urban poverty are examined in detail: the adjustment of industrial policy, the reform of state‐owned enterprises, evolution of the household registration system, and the transformation of the welfare state.     

Rainfall interception by Santa Monica's municipal urban forest

Effects of urban forests on rainfall interception and runoff reduction have been conceptualized, but not well quantified. In this study rainfall interception by street and park trees in Santa Monica, California is simulated. A mass and energy balance rainfall interception model is used to simulate rainfall interception processes (e.g., gross precipitation, free throughfall, canopy drip, stemflow, and evaporation). Annual rainfall interception by the 29,299 street and park trees was 193,168 m³ (6.6 m³/tree), or 1.6% of total precipitation. The annual value of avoided stormwater treatment and flood control costs associated with reduced runoff was $110,890 ($3.60/tree). Interception rate varied with tree species and sizes. Rainfall interception ranged from 15.3% (0.8 m³/tree) for a small Jacaranda mimosifolia (3.5 cm diameter at breast height) to 66.5% (20.8 m³/tree) for a mature Tristania conferta (38.1 cm). In a 25-year storm, interception by all street and park trees was 12,139.5 m³ (0.4%), each tree yielding $0.60 (0.4 m³/tree) in avoided flood control costs. Rainfall interception varied seasonally, averaging 14.8% during a 21.7 mm winter storm and 79.5% during a 20.3 mm summer storm for a large, deciduous Platanus acerifolia tree. Effects of differences in temporal precipitation patterns, tree population traits, and pruning practices on interception in Santa Monica, Modesto, and Sacramento, California are described.
