In recent years, with the performance of the national balanced development strategy of the regional economics, the inter-administrative regional construction of the new urban district has been a tendency aiming to remove the administrative division barrier and facilitate the regional economic development. However, problems also arise in the new urban district under the background of the inter-administrative region such as the predicament caused by the ubiquitous regional economic cooperation and competition as well as the public governance, the lack of the management main body qualifi cation and the monotonous means of coordination. Referring to the experiences of the US in the inter-administrative region administration in the metropolitan area, the author is to put forward countermeasures and suggestions from such two aspects as the management system and the working mechanism.展开更多

A control experiment is performed with two runs driven by the mean ERA-40 data during 1958-1977 and 1981 2000, respectively. The model reproduces the major decadal-scale circulation changes in late spring over East Asia, including a cooling in the upper troposphere and an anomalous meridional cell. Accordingly, the precipitation decrease is also captured in the southeast of the upper-level cooling region. To quantify the role of the upper-level cooling in the drought mechanism, a sensitivity experiment is further conducted with the cooling imposed in the upper troposphere. It is demonstrated that the upper-level cooling can generate the anomalous meridional cell and consequently the drought to the southeast of the cooling center. Therefore, upper tropospheric cooling should have played a dominant role in the observed late spring drought over Southeast China in recent decades.展开更多

Based on constructing the measurement index system of touristization and urbanization level, the evaluation model on the coupled and coordinated degree is used in this paper to measure the inter-provincial pattern of the coupled and coordinated relationship between touristization and urbanization in 31 provinces and autonomous regions in China. The results show that the coupled and coordinated relationship between touristization and urbanization is significantly different in different regions, which presents a gradient decline pattern of the highest in the east, the lower in the middle and the lowest in the west. In the future, measures should be taken to promote the coordinated development between touristization and urbanization in accordance with the regional differences and actual development needs.展开更多

In this paper, a methodological study in relation to the sustainable development of cross-border regions is conducted. Our particular interest focuses on the locational characteristics of cross-border regions as well as their economic implications to the cross-border governments. Based on a sustainable development model from which the optimal outputs of different kinds of border-regions can be derived, we try to methodologically help cross-border governments to reach a final agreement of sustainable development of natural and environmental resources.It is concluded that the methods by which the net benefits among the sub-regions can be redistributed may be: 1) to equalize the absolute values of net benefit among all sub-regions concerned; and 2) to equalize the relative values of net benefit among all sub-regions concerned.展开更多
