On the one hand, small town construction plays a positive role in adjustment of the industrial structure of the original peasant households and in the transfer of their employment towards non-agricultural industries. On the other hand the economic growth of the original peasant households is not so well sustainable, and is so fluctuating. Moreover, the unbalance of income distribution of the said households has been furthered, and small town construction has made the existing labor surplus of the original peasant households more serious, particularly the women labor surplus.展开更多

The main aim of the study was to record the opinions and attitudes of local inhabitants of the both regions towards environmental conditions, nature conservation, tourism, and to carry out their subsequent comparison. The objectives included that of ascertaining how and on which issues opinions and attitudes have the potential to be changed. The method of a structured interview and a random selection of interviewees provided us with 200 questionnaires in Sumava and 150 questionnaires in the Nove Hrady Mountains. The most noticeable differences between Sumava and Nove Hrady Mts. respondents were found with respect to the following topics: assessment of environmental conditions;the attitude to potential public access to the most endangered parts of the nature;perceptions about the influence of tourism on the cost of living. Similar reflections were found in the assessment of personal profit from the tourist industry in the region.展开更多

The Banjarese house, a type of Indonesian vernacutar architecture, is a typicat riverside dwetling that shows the strong relationship between the river and the inhabitants. In view of the number of Banjarese houses facing degradation as a riverside type of vernacutar architecture, a study is necessary. The characteristics of the inhabitants must be considered when observing the condition of the remaining houses. Therefore, this study aims to investigate the influence of inhabitant background on the physicat changes of Banjarese houses for future revitatization. A research was conducted in the embryo of Banjarmasin atong the Kuin riverside setttement in Kuin Utara sub-district through a door-to-door survey with a questionnaire. The exploration indicates the following： （1） the original form of art remaining houses has been attered, （2） most of the inhabitants are ctassified as a tow-income society, （3） the different characteristics of the present inhabitants change the physicat condition of houses, （4） the retationship of the current house condition to the socio-cutture and economy of the inhabitants prays a prominent rote in revitatizing Banjarese houses as a vatuabte asset.展开更多

[Methods]Field investigation and analysis were conducted on the social economic conditions, living environment, types of agricultural resources and their use in the main inhabitances of Pumi people including Yulong, Ninglang, Lanping and Weixi County in Yunnan. [Result] There are certain differences in social and economic situations of the four counties, and the ecological environment is generally good. The main agricultural resources in villages under investigation include beans and coarse cereals, while there are certain differences among other agricultural resources due to their location. [Conclusion] The living environment of the main inhabitances of Pumi people in Yunnan is good and there are plenty and characteristic agricultural resources which have certain potentiality for development in the future.展开更多

Like many other places in the Han nationality distributed regions, minority nationality inhabited regions are also facing the challenge of sustainable development in terms of both natural and human factors. Taking the Tibetan inhabited regions (TIR) in Sichuan Province as a case, this paper points out some major problems in the process of economic development in perspective of sustainability and leaves some hints for development strategies. While natural conditions such as geological instability are playing a major role to the environmental degradation, human activities and improper use of resources might constitute an important agent in the environmental deterioration. In order to promote local economic development and improve people’s living standard, sustainable planning is expected to be made and people’s awareness of sustainability should be strengthened.展开更多
