| By using theories from the relevant disciplines such as geography, mathematics, physics, ecology, and system sciences, this thesis develops a framework employing the concept of system entropy to represent the state function of the man-earth relationship system. In this framework the entropy change is used to show the development change of the system, and the entropy flow to express the flow among the spatial parts of the system. Following the framework, and based on a large set of household data from surveys, the thesis makes a quantitative analysis of the village-level man-earth relationship system from a micro-perspective. After a theoretical investigation, the thesis then suggests corresponding strategies to balance the unbalance trend of the village man-earth system from both perspectives of small-area and individuals. Apart from the introduction, it is divided into seven parts.First part reviews the study achievements on the man-earth relationship. On the basis of the introduction of the main concepts relative to the man-earth relationship system, this part reviews the current literature on this subject, delineate the ideological thread that runs through development of the man-earth relationship both in China and in the Western countries, and summarizes its study content, character, structure, function and effect factors and so on. Then after defining the boundary, scale, basic parts, structure and function, condition and evolution of the village man-earth relationship systems, the paper provides scientific accounting for choosing the micro-space perspective, in terms of the nature village and the survey household. This is followed by a brief introduction to three villages (Wugou, Hutuo, Xiaonan villages) investigated in this paper, explaining data origins and data processing and so on.Part two makes a quantitative analysis on the disorder extent of human activity of the village man-earth relationship systems in the three villages investigated. Taking the negative effect as standard which the household activity puts on its environment, the author designs a index system to reflect the disorder extent of household activities in the villages, which consists of four groups and 52 indicators. In accordance with conditions of entropy method and the present condition, the improved entropy method is adopted to assess the index weightiness. By using the model of the disorder extent of household activity, the disorder extent of household activity in study villages was evaluated. The analyzing results show that, in four types of household activities in the scope of village, the disorder effect generated by the secondary industry is strongest, which by commerce and service activities is stronger, and which by agricultural activity is strong, and which generated by household reproduction and live activity is relatively weak. From 1990 to 2002, the disorder extent of household activities in three villages becomes increasing in turn. In terms of their seasonal change,the household activities of Wugou and Hutuo village mostly fasten on two traditional busy seasons in agriculture, however Xiaonan village is in the other way, that is to say, the intensity of household activities is weak in the traditional busy seasons, which is strong around Chinese New Year. In terms of monthly diversity of household activities, Hutuo village is greatest, Wugou village is greater, and Xiaonan village is relatively weak. In terms of annual diversity of household activities, the change of Xiaonan village is greatest, following by Wugou village, and Hutuo village.Part three analyzes the village's carrying capacity. Carrying capacity is subject to natural environment, nature resource and human activities. Results show that the carrying capacity of three villages rises in turn in the year of 2002. In the structure of the village carrying capacity, the contribution extent of nature carrying capacity is almost equal to the one of human carrying capacity in 1990; however the share of the later has risen up in evidence in the year...
