This framework of agro - ecosystem productivity evaluation is expected to be an innovative attempt comparing to the similar research method before . 2 . the emergy evaluation results show that ( 1 ) the primary system productivity have risen greatly since 1990 in this region 首次引入了能值( emergy )分析方法和生态系统服务( ecosystemservice )价值测算方法并进行了修正，这在同类研究方法上是一种具有创新意义的尝试。
Taking zhijin county as a concrete case , the article calculated emergy of local ecological and economic system qualitatively and quantitatively against data in the year of 2003 with theory of ecological economics and system coupling under which material flow , energy flow and information flow could be manifested actually , and then analyzed the ecological and economic system coupling status in the year of 2003 with emergy indexes and emergy index model for sustainable development 本文利用2003年数据,驾驭生态经济学和系统耦合的理论,以织金县为例,运用能准确地研究生态经济系统的物质流、能量流和信息流的分析方法? ?能值分析法,定量定性结合,计算织金县生态系统和经济系统能值,然后利用相关耦合指标和能值可持续发展指数模型分析2003年织金县生态经济系统耦合现状。
1 . this paper first puts forward the framework of agro - ecosystem productivity constituted by primary productivity . secondary productivity . economic productivity of peasants household , ecosystem services productivity and their evaluation indices , in which the approach of emergy analysis and ecosystem service was introduced and applied after being revised 论文的主要进展归纳如下： (一)本文创造性地提出了由区域初级生产力、次级生产力、农户经济生产力以及生态系统服务生产力四部分组成的农业生态系统生产力分析框架模型及评价指标体系。
Compared the present environmental evaluation , and pointed out the imperfection ; analysis the relation between the environmental problem with the energy from two aspects of environment and economic with energy and environment . 2 . come up with the energy accounting structure of eco - economic system , and use ema to calculate the emergy of the five flows of beijing from 1995 to 2000 本论文的研究工作主要包括以下几个方面： （ 1 ）分析了现有的环境评价体系中的不足之处，以环境协调性评估lca的评价方法为例，逐项列出系统能量损耗，从环境与经济、能源与环境两个方面来探讨能源与环境相互作用的机理。
By minitab predict the relation between population and consumption of source , which reflect emergy structure and energy base of beijing . this thesis provides suggestions on continuous development and energy policy in beijing . at the same time , the result of this research also provides some theoretical base for founding " environment - energy - economy " intersectional subject 本文提出的以能值分析为基础的经济-环境系统的研究方法，为完善城市环境评价提供了参考；同时，以能量为测度单位的定量分析，可以为建立“环境-能源-经济”交叉学科提供部分基础理论，为城市能源政策和可持续发展规划作了有益的探索。
With the development of society , quite a few environmental problems had emerged , there had been several environmental evaluations in the world , but their objects were almost about air , water and suchlike , while energy was seldom involved . in order to find out fundamental reason of the interaction of the environmental issues and the consumption of energy , emergy analysis ( ema ) was applied in this thesis 面对当前在人口、资源、环境与经济发展之间的矛盾，国内外出现了多种环境评价体系和研究方法，但由于这些评价体系大都是针对某种具体对象而提出的，例如对大气质量的评价、对水质的评价等，而对环境与能量消耗相互影响的底层原因及定量化很少涉及。
Abstract : in this paper on foundation to have devised a new seeking solutions method for mechanism , 25 groups of the basic functions have been solved and a whole system of the mechanism kins , that comprises a disposing material , a disposing emergy and a disposing information , has been showed . through a comprehensive analysis to the three kinds of mechanism s construction their construction ralationaties have been discovered 文摘:本文在开发机构功能基本类型求解方法的基础上，系统求得其解计25组，展示了由物料处理、能量处理和信息处理三类组成的机构类型完整体系；并从三类机构的构造综合分析中，发现了它们的构造理性。
