The total organic carbon (TOC) content series from the lake sediment of Minqin Basin (100°57′–104°57′E, 37°48′–39°17′N) in northwestern China, which has a 10 000-year-long paleo-climatic prox...The total organic carbon (TOC) content series from the lake sediment of Minqin Basin (100°57′–104°57′E, 37°48′–39°17′N) in northwestern China, which has a 10 000-year-long paleo-climatic proxy record, was used to analyze the Holocene climate changes in the local region. The proxy record was established in the Sanjiaocheng (SJC), Triangle Town in Chinese, Section (103°20′25″E, 39°00′38″N), which is located at the northwestern boundary of the present Asian summer monsoon in China, and is sensitive to global environmental and climate changes. Applying singular spectrum analysis (SSA) to the TOC series, principal climatic oscillations and periodical changes were studied. The results reveal 3 major patterns of climate change regulated by reconstructed components (RCs). The first pattern is natural long-term trend of climatic change in the local area (Minqin Basin), indicating a relatively wetter stage in early Holocene (starting at 9.5 kaBP), and a relatively dryer stage with a strong lake desiccation and a declined vegetation cover in mid-Holocene (during 7–6 kaBP). From 4.0 kaBP to the present, there has been a gradually decreasing trend in the third reconstructed component (RC3) showing that the local climate changed again into a dryer stage. The second pattern shows millennial-centennial scale oscillations containing cycles of 1 600 and 800 years that have been present throughout almost the entire Holocene period of the last 10 000 years. The third pattern is a millennial-centennial scale variation with a relatively smaller amplitude and unclear cycles showing a nonlinear interaction within the earth’s climate systems.展开更多

As horizontally shown by cross-section data, significant hukou identity differences exist in the subjective happiness of households reflected in life satisfaction. However, the traditional view that ＂rural residents are subjectively happier than urban residents＂ is not verified in this study. From a vertical perspective of tracing data, the estimation results of the DID model and the PSM model indicate that a change of hukou identity for rural residents has a significantly positive effect on their subjective happiness, lending credence to the saying that ＂cities make life better＂.展开更多

This study was implemented between May and July of 2011 to understand the local community perception of new residents living in five rural areas, and one city of Penghu, and to understand the community perceptions of these new residents. This includes： the new residents＇ feelings about the community, the new residents＇ feelings about interaction with the locals, multicultural acceptance of the community, and the new residents＇ feelings about participation in local activities. According to the parameters of this research, quantitative research methodology was adopted. After questionnaire studies and data analysis, the key findings are thus： New residents living areas have significant impact on the community perceptions of them, especially in two areas： the new resident＇s feeling relating to the community environment and their perception of interaction with the locals.展开更多
