China's Regional Policies:Progress of the 11~(th) Five Year Plan Period and Prospect of the 12~(th) Five Year Plan Period

During the 11th Five Year Plan period,China improved its policy system for the overall strategy of regional development,and established and completed the policies intended for the promotion of regional cooperation and interaction.Thereupon,regional development in China took on a series of positive changes such as the enhancement of coordination.During the 12th Five Year Plan period,China will fully implement and continuously improve the policy measures for development in its four major regions,strengthen differentiated guidance to different regions in line with the planning for major function-oriented zones,and accelerate the establishment of basic systems that facilitate coordinated regional development.

Binding of polycyclic aromatic hydrocarbons by humic acids formed during composting

Binding of two model polycyclic aromatic hydrocarbons (PAHs), phenanthrene and pyrene, by humic acids (HAs) isolated from an organic substrate at different stages of composting and a soil was investigated using a batch fluorescence quenching method and the modified Freundlich model. With respect to soil HA, the organic substrate HA fractions were characterized by larger binding affinities for both phenanthrene and pyrene. Further, isotherm deviation from linearity was larger for soil HA than for organic substrate HAs, indicating a larger heterogeneity of binding sites in the former. The composting process decreased the binding affinity and increased the heterogeneity of binding sites of HAs. The changes undergone by the HA fraction during composting may be expected to contribute to facilitate microbial accessibility to PAHs. The results obtained also suggest that bioremediation of PAH-contaminated soils with matured compost, rather than with fresh organic amendments, may result in faster and more effective cleanup.     

区域性煤矿百万吨死亡率指标的宏观预测研究

为了对煤矿安全状况进行宏观预测,提出区域性煤矿安全状况评价指标体系并建立了以煤矿百万吨死亡率指标标征区域性煤矿安全状况的灰色预测模型。在对煤矿综合机械化采煤率、大型煤矿产量比例、原煤全员效率指标预测分析的基础上,利用多元回归法综合预测煤矿百万吨死亡率指标。实例计算证明:建立的预测模型具有输入数据少、建模简单、计算快捷等优点;客观地反映出区域性的煤矿安全状况;该模型可进行煤矿安全的短期预测,并为制定煤矿安全控制指标提供理论依据。     

1961~2015年西南地区降水及洪涝指数空间分布特征

利用西南地区98个气象站连续完整的日降水序列数据,整合降水强度、持续性指数及等级指数形成降水指数体系并研究该区域降水及洪涝指数的空间分布特征,得到以下主要结论：（1） 1961~2015年,西南地区年降水量（PRCPTOT）与极端降水量（R95PTOT）都呈现出“东多西少、南多北少”的分布形态;持续降水日数（CWD）则表现为“南高北低、西高东低”的分布格局。区域多年平 均PRCPTOT、R95PTOT、CWD分别以-13.12 mm/10 a、1.34 mm/10 a、-0.29 d/10 a的速率变化。（2）西南地区不同等级降水日数具有相似的空间分布特征,均呈现出“南高北低、东高西低”的分布形态。（3）西南地区洪涝强度指数呈由东北向西南递减的分布特征;降水总量越多的地区,洪涝强度反而越低,主要由于单站洪涝强度表征的是降水的波动情况,降水量越多波动越不明显。21世纪以来,该 地区洪涝等级以重级为主,2010年以来连续多年出现特重级洪涝。此外,洪涝强度越大,区域性年度灾害等级越高。该研究对于掌握西南地区极端气候变化规律,从而服务于防灾减灾具有一定的理论意义。     

Future implications of urban intensification on residential water demand

Over recent decades Auckland, New Zealand, metropolitan area has vastly expanded as a result of rapid population growth and low-density housing developments. In order to manage the uncontrolled low-density urban sprawl, Auckland Council proposed a compact city model through promoting higher density housing developments. In order to understand the implications of this transition on future residential water demand, this study first evaluated water consumption in three major housing types in Auckland including single houses, low-rise and high-rise apartments. Using the geographic information system, the water consumption information, estimated from a large sample of 60,000 dwellings across Auckland, was subsequently integrated with the Proposed Auckland Unitary Plan outlining the future housing composition over different areas in Auckland. Through developing different growth scenarios, the study showed that the housing transition from single houses to more intensified multi-unit houses cannot considerably affect the average per capita water consumption in Auckland.     

安徽省市级区域发展的空间结构演变分析

以市级区域为空间结构研究对象,分析安徽省20世纪80年代以来区域经济空间结构的演化过程。结果表明：①安徽省各市级区域在近20年的发展中,区域差异空间格局整体上变化不大,20世纪80年代初期经济发达的地区现在仍为发达区,原先落后的地区仍落后;②1980年以来,工业化进程的空间差异与区域社会经济发展的空间差异具有很大的相似性,表明工业化是推动区域经济发展的重要力量;③通过分析区域发展差异的空间机制得出：轴线的地位差异显著,以贯穿南北的中轴线和沿江轴线为主,形成经济实力中心,而其它地区相对落后,形成了明显的中心-边缘模式。
