以耗散结构理论为基础,根据现有数据,建立了于田绿洲社会经济系统可持续发展状况评估的指标体系。并运用信息熵计算法,对于田绿洲社会经济系统的可持续发展状况进行分析。结果表明,11980-2010年,于田绿洲社会经济系统的总熵变波动变化,但整体上处于下降趋势,说明于田绿洲社会经济可持续发展状况良好;21980-2010年,系统的熵产生指标中,第三产业生产总值、农牧民人均纯收入和第二产业总产值的权重最大;在系统的熵流指标中,地方财政支出、农村用电量和化肥使用量的权重最大。
Based on the theory of dissipative structure and based on the existing data, an index system for assessing the sustainable development of Yutian Oasis socio-economic system was established. And uses the method of information entropy to analyze the sustainable development of social and economic system of Tian Oasis. The results show that from1980to2010, the total entropy change of Yutian oasis socio-economic system fluctuates, but on the whole, it shows a declining trend, indicating that the Yutian oasis has a good social and economic sustainable development. From1998to2010, the entropy production index Among them, among the entropy flow indicators of the system, the local fiscal expenditures, rural electricity consumption and fertilizer use have the most weight.
