Soil Total Organic Carbon, Δ13c Values And Their Responses To The Soil Core Transferring Experiment From High- To Low-Elevation Forest Along Natural Altitudinal Transect Of Old Temperate Volcanic Forest Soils, Zhang Xin-Yu, Meng Xian-Jing, Fan Jin-Juan, Gao Lu-Peng, Sun Xiao-Min

International Congress on Environmental Modelling and Software

In this study, the responses of soil organic carbon and δ13C values to soil warming were conducted by relocating intact soil cores from high- to low-elevation forests for one year along a natural altitudinal transect in the northern slope of Changbai Mountain. As expected, the soil-core relocation caused significant increase in soil temperature but made no significant effect on soil moisture. The results showed that after one year incubation, soil relocation significantly decreased TOC contents, and δ13C decreased. Pearson correlation analysis demonstrates that TOC content was negatively related to soil temperature but positively related to soil moisture. After one-year simulated …

Environmental Information Management Systems As Templates For Successful Environmental Decision Support, N. W. T. Quinn Jul 2010

Environmental Information Management Systems As Templates For Successful Environmental Decision Support, N. W. T. Quinn

International Congress on Environmental Modelling and Software

The mantra that successful Environmental Decision Support Systems (EDSS’s) are those that benefit from a high level of end-user involvement during the design phase and subsequent implementation is well founded. However the practical matter of eliciting the relevant information from stakeholders to develop a useful and robust EDSS is rarely adequate and this weakness contributes to the high rate of failed EDSS’s. Stakeholders sometimes have difficulty articulating the decisions they are called upon to make and cannot definitely describe the bounds of the decision space within which they operate. The EDSS developer is challenged by having to understand the system …

Carma: Scalability With Approximate-Model-Based Adaptation, John D. Hastings, Alexandre V. Latchininsky, Scott P. Schell

International Congress on Environmental Modelling and Software

Many complex physical systems such as biological systems are characterized both by incomplete models and limited empirical data. Accurate prediction of the behavior of such systems requires exploitation of multiple, individually incomplete, knowledge sources. Our approach, called approximate-model-based adaptation, utilizes case-based reasoning to provide an approximate solution and model-based reasoning to adapt this approximation into a more precise solution. This approach is implemented in CARMA, a decision-support system for grasshopper infestation advising which models experts and has been successfully used since 1996. Initially focused on rangeland grasshoppers within the state of Wyoming, CARMA’s capabilities have been extended to support the …

An Integrated Assessment Approach To Linking Biophysical Modelling And Economic Valuation Tools, Marit E. Kragt, James Bennett, A. J. Jakeman

International Congress on Environmental Modelling and Software

Catchment natural resource management (NRM) involves complex decisions that affect a wide variety of values, issues and stakeholders. Designing efficient NRM policies requires assessments of the environmental impacts, and costs and benefits of management interventions in an integrated manner. However, despite the need for integrated assessment (IA), there are few comprehensive frameworks that integrate biophysical models with economic valuation. Cost-benefit analysis (CBA) is a framework that can support efficient NRM by assessing and comparing the total social costs and benefits of management interventions. However, the environmental modelling that has underpinned CBA has typically been poor, reducing the credibility of the …
