In order to subdivide the market during the process of project planning and orient the group of client, then determine the sale price; on the condition that the traditional orientation procedure cant grasp the payment capability of the aim client, the anthors can adapt the powerful finance analysis ability of EXEL to design the procedure of determining the purchasing power and payments ability of the aim client, and shape a set of orientation system based on quantitative analysis method. The result is, the character of the aim client can be grasp accurately depend on this orientation system, and providing a scientific gist for the accurate orientation of price and lowing the risk of investment etc. 相似文献

通过生态系统服务价值评估途径制定森林生态补偿标准,意味着立足于市场评估森林生态系统服务的经济价值。但是,一些问题困扰着评估实践,选择哪些指标用于评估就是难题之一。评估存量还是流量,选择指标时应遵循的原则,也必须事先得到明确界定。本研究应用生态学和经济学理论,提出了评估本身应遵循的范畴和原则,以及应当选取的价值类型和评估指标。 相似文献

生态补偿是目前生态学研究的热点,生态补偿的关键问题是补偿标准的确定.将三江源自然保护区的生态移民作为对象,结合确定补偿标准的方法的特点,针对研究区域的实际情况以及我国生态补偿存在的主要问题,运用不同的方法提出了生态移民补偿标准的不同方案,所采用的方法分别是:牲畜机会成本法、草场机会成本法、以果洛新村和河源新村两个移民新村为例的地区发展差异法.结果表明:3种方法的侧重点各不相同,所确定的平均生态补偿标准也稍有不同,分别为1.39万元·户-1·a-1;1.03万元·户-1·a-1;1.1万元·户-1·a-1.研究为确定三江源自然保护区生态补偿的标准提供了科学依据,也为其他地区提供一定的借鉴. 相似文献

当初步遏制草地退化后,我国当前迫切需要对草地管理政策进行优化和调整,进而更好地通过草畜平衡和生态补贴实现生态保育和牧民利益的协调和可持续发展目标。长达90年的美国公共放牧地政策可以为我国调整和优化草地管理政策提供借鉴。美国经验表明,实现草地生态保育需要在社会共识、法律体系和行政管理等方面,牢固地树立和实现草地的多重功能和生态系统服务理念。进一步地,公有的草地产权制度是保障草地多重生态系统服务的法律前提,非牧产业发展是实现草地多重功能的经济基础,精细的行政管理是实现草地生产生态平衡的技术保障,多种利益主体参与是实现草地管理制度改革的活力来源。美国草地管理制度发展的曲折反复,也说明了生态管理政策的失效和调整,禁牧和监管强度的张弛反复,不同利益集团的矛盾诉求和博弈消长,都是草地治理中的正常情况。我国草地治理也可能经历复杂曲折的过程。在下一阶段,草地产权的优化、行政管理的精细化、牧民利益和生态保育目标的协调,是实现我国草地可持续治理的核心要务。 相似文献

《公羊传》“子以其指”一句含义如何，学界素有争论。或附会以天地五行之数，或坐实为残指、骈指、小指。然揆之以理，皆有未惬。邾人此言，实与立嗣原则密切相关，读者宜从屈指而数以计长幼的层面上去理解。唯有如此，邾人答辞方称结构对称、语义明朗，《公羊》纪事方称自守法度、与《左》无违。 相似文献

由于环境过度利用、资源过度开发等原因使我国面临发展社会经济和保护环境的双重压力,因此有必要建立健全生态补偿机制,尤其是大力完善生态补偿横向财政转移支付方式。笔者从阐述生态补偿机制与生态补偿财政转移支付的内涵入手,实证分析了我国现行生态补偿财政转移支付机制的问题与不足,在此基础上提出了应该建立并完善生态补偿横向财政转移支付的建议。 相似文献

This study investigates the combined impact of carbon and bioenergy markets on upland oak dominated mixed hardwood forests in the Central Hardwood Forest Region (CHFR) of the United States. A modification of the Hartman model was used for the economic analysis of carbon sequestration and using wood-based biomass for bioenergy. A life-cycle assessment was used to determine the amount of carbon sequestered due to stand growth and emitted during harvesting and decay of wood products. Two scenarios were taken, one where additionality of carbon is considered and the other where it is not. Sensitivity analysis was done with the range of carbon and bioenergy prices. The results show that net carbon payments have more impact on land expectation value (LEV) when additionality is not considered; in contrast, bioenergy payments have more impact on LEV when additionality is considered. Carbon and bioenergy prices also influenced the amount of stand level supply of forest products and carbon in both scenarios. In general, sawtimber, wood bioenergy, and carbon supply increased with an increase in carbon prices, whereas, pulpwood supply decreased. With few exceptions at higher carbon prices, bioenergy supply decreased with the increase in wood bioenergy prices, showing a backward bending supply curve in both scenarios. 相似文献

On the basis of statistic data from 1984 to 2004 and regression analysis of influencing factors of foreign exchange reserves(FER),this article comes to the conclusion: current accounts,capital accounts,real GD Pshow remarkable positive correlation with the demand of FER,and exchange rate shows inverse correlation with the demand of FER,while foreign loans balance and FER show little correlation.On addition,the article analyzs the trend of(China's) FER fluctuation and clarifies the interaction of the trend and remarkable interpretative variables. 相似文献
