济源市省庄地热区地质条件及成因特征

济源市省庄地热属于异常增温热水型及干热岩型地热区,是中国北方非火山岩浆岩区地热异常的典型地热区,地热水是大气降水通过盘古寺深大断层深循环的结果。地热分布受盘古寺断层、五龙口断层及次级断层的控制,并在断层交汇部位显示温度异常。热源来自于北部山区补给沿断层径流的深循环水。深循环水水温较高,与浅部受大气降水及地表水补给的冷水相混合。     

Socioeconomic Correlates of Increasing Crime Rates in Smaller Communities

This research analyzes changes in crime rates by city size and determines the extent to which these changes can be explained by socioeconomic variables. More particularly it addresses rates of change in mean crime rates for violent and property crime between 1976–1984 and 1985–1994 for all U. S. cities, then compares results to Ohio cities. It provides a detailed analysis of changing crime rates in 111 Ohio cities with populations between 10,000 and 99,999 inhabitants and attempts to account for crime differentials between these cities employing linear regression and factor analysis. Results indicate that crime is significantly related to poverty and its associated conditions and processes.

The role of the border city Hunchun on Tumen River, China

Since the Tumen River Area Development Project(TRADP) was launched in 1991, Hunchun city located between North Korea and Russia along the river corridor, has become an important and unique border city. Hunchun, formerly a strategic military city, is emerging as an international trade linkage center through Satouz and Quanhe on the North Korea side and through Changlinzi on the Russian side. Furthermore, the establishment and operation of the Hunchun Border Economic Cooperation Zone (HBECZ) in the city is becoming the main source of the growth, providing a new role for the border city. Its underlying economic momentum comes from the combination of the Chinese-Korean labor force and foreign investment and technology transferred from Korea, Japan, and others. The most important expected new role for Hunchun is as a new 21st century entrepot connection between the Pacific rim and Eurasia by rail and trunk lines, and as a new regional center of the border region based on both a newly generated urban subsystem and the increasing informal sector of cross border business. However, there are many obstacles to overcome in the near future, such as the possible military tensions among the three border nations, the guarantee of free entries and sailing on the Tumen river, and agreements concerning environmental conservation.

Methodological aspects of surveying the volume, structure, activities and perceptions of city centre visitors

Counting pedestrians on a street and visitors entering a store is a method used to measure the attractiveness of these places. Their volumes are governed by daily, weekly, monthly and yearly cycles and are subject to random influences. This must be taken into account especially where comparison counts reveal changes. When single streets or stores are counted, it must be ascertained whether this figure is representative of the whole city centre and its retailing. Pedestrian volumes can be used for adjusting interview samples to the distribution in time and space of the city centre visitors. Counts of the qualitative characteristics of the pedestrian with respect to composition of groups reveal that surveys among pedestrians are biased in relation to the size of the group. Special attention in surveys should be given to the linking of activities. Whereas much emphasis is given to the accessibility of the city centre from outside, the ‘inner accessibility’ of the city centre is just as important. Long distances are often walked and many destinations visited. This is best recorded by conducting interviews at public transport stops and car parks. The attractiveness of the city centre depends not only on its physical structures but very much on the subjective perception of them; therefore judgements on accessibility, goods and services offered and the urban ambiance should be recorded. Retailer's attitudes concerning the qualities of the city centre should also be compiled for comparison. This revised version was published online in July 2006 with corrections to the Cover Date.
