基于人口生活用水的入户实地调查,结合中国北方县域单元人口和气象台站降水量,厘定了不同降水带及其不同时段的人均生活耗水系数(η),同时得出相应地带不同时代的人口生活耗水量。研究表明:不同降水带的η值从20世纪50年代到90年代增长... 基于人口生活用水的入户实地调查,结合中国北方县域单元人口和气象台站降水量,厘定了不同降水带及其不同时段的人均生活耗水系数(η),同时得出相应地带不同时代的人口生活耗水量。研究表明:不同降水带的η值从20世纪50年代到90年代增长速度加快,100~200、200~400、400~600和600~800mm降水带η值增加幅度依次为1.84倍、2.62倍、2.84倍和2.68倍;从不同降水带来看,人口生活耗水量从20世纪50年代到90年代都是400~600mm降水带最高,然后向两边依次递减。降水带人口生活耗水量与相应降水带面积的比值(k)普遍增加,表明中国北方各降水带人口生活耗水量对各带的生态环境压力在增大。研究可为估算不同地带人口生活用水量、建立家户层次的水资源高效利用模式提供参考。 展开更多

Based on the overall analysis of the floating population among big and medium-sized cities in China,this paper, by means of statistics and questionnaires, makes a systematical study on the migratory features of the floating population in Mianyang, its employment structure, migrating causes and channels. According to the findings, the author finds a fact that with the strategy of Western Development, and with the construction of science and technology city of Mianyang, the migrating in Mianyang conforms to the general patterns of the migration, which has happened in those big and medium-sized cities in China.In addition,the city has a new but unique feature — economic factor, as the driving force of population migration, is quite distinct from that of those citiesin eastern areas of China. 展开更多

For the aim at exploring differences on personality traits between excessive online game users and non-excessive users in Japan, an online survey was conducted using psychological scales measuring addictive tendencies for online gaming, depressive tendencies, aggression, and self-concealment. The results revealed that excessive online game users having addictive tendencies in Japan had lack of self-esteem as one of depressive tendencies, high aggressive tendencies, and low tendency of self-disclosure, in contrast with non-excessive users. Moreover, it was suggested that these users had a confidence in the society based on contributive behaviors in multi-player groups of online gaming. 展开更多
