Analysis of Income Structure of Farmer （Herdsman） of the Tibet Autonomous Region

Based on the sampling data this paper analyzes income structure of farmer (herdsman) of the Tibet Autonomous Region, including source, characteristics and cash. Situation of income structures and income sources of the farmers in different areas (agricultural, animal husbandry areas and half agricultural and half animal husbandry areas etc. )was approached. The following features were found through an analysis of surveyed data; ① In Tibetan peasant household goods and products instead of money, disposable income and cash are very little. ② The variety index of income is higher in the outskirt than it in rural, the index has a direct bearing on net income. ③ The income ways are simplistic and outdate in the poor households, they have no ability to resist and guard against any risk, it is very difficult to increase their receipts. ④ The living standard in agricultural areas is better than in pastoral areas, it is the worst in half agriculture and half animal husbandry areas.

Two Village Ecosystems in the Upper Minjiang River, China： A Comparison of Emergy Flow

By using the concept of emergy and method of emergy analysis, this paper has studied two mountain settlement (village) ecosystems in two aspects: input and output of energy in the agro-systems and the use of fuel energy. The result reveals that the settlement agro-system in the valley of Minjiang River is better in both structure and function than that at the so-called half-high mountain. The former one is higher than the latter one regarding such indices as emergy yield ratio, labor productivity of emergy and emergy sustainable index, but lower than the latter one regarding environmental loading ratio. In terms of fuel emergy, the settlement in the valley enjoys more diversified sources and is less depending on bio-energy while the settlement at the half-high mountain has only one source (i. e. fuel wood), much depending on bio-energy, may exert a greater pressure on environment.
