基于土地发展权的征地补偿价格研究——以河南省周口市为例

首先,从理论角度探讨土地发展权内在机理,分析现行征地补偿价格的不足,提出了征地补偿价格应为集体农用土地价格与土地发展权价格之和,并以此构建基于土地发展权的征地补偿定价模型;其次,以周口市为例,应用构建的定价模型及农户问卷调查分析方法,测算了各县(区)基于土地发展权的征地补偿价格,并对测算结果和现行征地补偿价格进行了对比分析;最后,提出应从法律上确保农民土地发展权的权益,并在今后征地工作中逐步改革现行征地补偿制度,构建公平合理的征地补偿分配机制。     

The observed currents in summer in the Bohai Sea

A harmonic method was used to analyze the tidal currents observed in summer at 11 stations made from 1996 to 2001 in the Bohai Sea, China. Data was compared among different instruments and intervals. Elliptic elements were calculated based on harmonic constants, of which vertical distributions of the maximum speed and rotation direction were discussed for understanding the characteristics of diurnal and semi-diurnal tidal current components. The results indicate that the maximum speed of M2 tidal current component is much larger than that of K1; the rotation direction of M2 tidal current constituent is clockwise in the central part of the Bohai Sea and in the Laizhou Bay, but anticlockwise in the Liaodong Bay and Bohai Bay. For K1 tidal current constituent, it is clockwise in the central Bohai Sea but anti-clockwise in the Laizhou Bay and Liaodong Bay. The tidal currents in most stations in the Bohai Sea were regular semidiurnal except for those in the central Bohai Sea, being irregular semidiurnal.
