生态环境价值评估方法浅析

生态环境的多样性及其经济价值的复杂性决定了在对生态环境经济价值进行评估时需要采用多种不同的评估方法。根据是否存在现存市场或替代市场可将常用的生态环境价值评估方法分为三大类:直接市场法、揭示偏好法及陈述偏好法。鉴于经济增长及可持续发展与生态环境之间不可分割的关系,在政策制定及投资决策中需纳入对生态环境影响的评估,将其作为重要的考量因素之一。政策制定者或者决策者需要考虑不同政策或不同投资决策下生态环境价值的变动以及结构的变化,同时结合经济指标(如经济增长、投资回报等),对不同政策及投资进行比较。

Design and Applications of Land Resources and Ecological Environment Information System: A Case Study of Zigui County in the Three Gorges Area of China

The design and applications of a land information system built upon ARC/INFO and ArcView are presented. The proposed system not only maintains all the advantages of the more conventional implementations but also enhances them in the following ways: 1) the application program interfaces (API) are used to transmit data and messages among different parts of the system; 2) the integrated system can support studies on land evaluations and ecological analyses by efficient management of attribute and spatial data and 3) correspondingly, spatial records and attributive records are linked by the same identifiers (ID). A case study application in Zigui County of the Three Gorges Area in China demonstrates that the system could employ land-use maps and land property data to predicate and analyze the land utilization changes in the past, present and future. The ecological environment analysis can be carried out with the data of land, economics and terrain map used, showing that the system can be widely applied, especially to survey land and environment resources in the countryside area.

Ecological Evaluation Models for Environmental Engineering in Taiwan

This study is aimed to investigate and analyze the ecological technology around ecological environment resources of engineering in Taiwan. In Taiwan, the natural and artificial material applied in the ecological technology in internal currently, usually lack of evaluation for applicative conditions. Hence, this study carried on the whole research and identifications to draft the eco-materials of ecological technology. The evaluation models of applied materials for ecological technology were proposed. The quantitative score were obtained by expert＇s person evaluation. Three models were proposed to quantify the effects of applied materials on the ecological environment. The statistical procedures were adopted to compare the performance of these materials for ecological technology. The results indicated that the comparison of applied materials can be treated by quantitative analysis. For the further analysis, more evaluated data from expert＇s experience need to be collected then the bias of person subject can be reduced. In addition to reach the benefits in the respects of ecosystem, society, economy and function, also practice the comprehensive effects in ecological technology.
