A suite of regional allometric aboveground biomass functions were derived for Betula pubescens and Betula pendula for Norwegian conditions. The data consisted of 67 trees sampled throughout Norway. A total of 14 component functions were developed for total aboveground, total stem, stemwood, stem bark, live crown, live branch, leaf, and dead branch biomass using combinations of diameter at breast height and height as predictor variables. Application of the derived functions to existing local southern Norwegian mountain birch and regional Swedish biomass datasets indicated an overall good predictive ability of the developed functions. However, the functions produced slight underestimates, suggesting that the respective birch populations had differing biomass allocation patterns. When the developed functions were applied to Norwegian National Forest Inventory data, they produced slightly higher biomass stock and stock change estimates than what is obtained using existing Swedish functions. The higher estimates were evident in the north, central, and western part of Norway, while estimates were similar in southeastern Norway where growing conditions are most similar to Swedish conditions. The analysis indicates that the derived functions are the best available for regional birch biomass stock and stock change estimation in Norway. 相似文献

孙海燕、周世健等对P范分布及其参数估计理论作出了重大贡献,但他们提出了两种不同形式的P范分布密度函数.针对延续了10年的P范分布密度函数的形式差异和争议,讨论了两种不同形式的多元P范分布密度函数及其数据处理的特点,证明了两种不同形式的多元P范分布密度函数等价,从而统一了多元P范分布的理论基础,并提出有关的符号建议,以便于多元P范分布理论在数据处理中的推广应用. 相似文献

The study presents four ways to formulate a landscape level forest planning model for group planning using a heuristic optimization method called ‘HERO’. The HERO method is composed of two primary steps: first, forest management goals are defined; then a management plan is sought to fulfill the defined goals. The planning models consider the landscape (whole area) and forest holdings as separate hierarchical levels. Within the planning models, each participant's forest management goals are defined using additive priority functions consisting of weighted sub-utility and/or achievement functions. Maximizing the achievement function minimizes the deviation from the target value for the corresponding goal variable. (i) The integrated top-down model uses achievement functions on the landscape level and sub-utility functions on the individual holding level; while (ii) the integrated bottom-up model uses achievement functions on the holding level and sub-utility functions on the landscape level. (iii) The integrated utility maximization model consists of weighted sub-utility functions on both the landscape and the individual holding levels and (iv) the integrated regret minimization model uses achievement functions on both levels. The use of different priority models was illustrated in a case study, which consisted of four neighboring private land holdings. In general, the priority models worked in a logical way. Large deviations from the targets could be prevented by using achievement functions in the overall priority models. On the other hand, the differences between the models were not very large, and the results of only one case cannot be generalized. It seems that all the alternative priority models might have use in different planning situations. However, interactive use of the models should be preferred. 相似文献

Biodiversity in Asia is reviewed here from both scientific and socio-economic perspectives. Biodiversity in Asia has been
very high, for historical and climatic reasons; however, this situation has been changing rapidly, due to population growth
and economic development. The forest biodiversity in this region has both global and local value, yet it is seriously threatened.
As natural capital, biodiversity functions in a variety of ways: production and regulation functions have global value, while
habitat and information functions have social and cultural value, as well as local importance. Sustainable forest management
is dependent on the regulatory functions of the ecosystem and biodiversity. Sometimes the functions of forests or biodiversity
make conflict. Moreover, biodiversity has an information function related to sustainability via local knowledge and culture.
Levin’s (1999) proposals are helpful as a conceptual framework for developing sustainable management for Asian forests. 相似文献
