国外生物量模型概述

通过对大量国外文献的阅读,总结了国外生物量研究历史发展过程,对当今热点生物量模型进行列举分析。指出当今国外应用广泛的经验方程与异速生长方程、广义异速生长方程、分形几何和管道模型等热点生物量方程形式;归纳了生物量计量参数、生物量分配等生物量研究热点问题的现状;最后分析了生物量研究发展趋势,通过借鉴国外经验,得出中国生物量研究应扩展生物量研究范围、规范参数、尺度转换等方面,明确方向,加强技术开发,科技投入的结论。

Foreign Studies on Biomass model

The aim was to describe the current foreign study of biomass model and to summarize the developing trend and heated topic of biomass model study. The developing process of foreign study on biomass is concluded and the heated biomass model is analyzed on the basis of plenty of foreign thesis. This thesis gave a conclusion on the broadly applied heated biomass equations such as empirical equation, allometric equation, generalized allometric equation, fractal geometry, channel model etc. This thesis also concluded the current study situation of biomass calculation parameters, biomass allocation etc. According to the developing trend of biomass study, the biomass study will broaden the research spectrum and depth and the research will center on the perspectives on the survival and sustainable development on human beings. According to the foreign experience, the biomass study in China should focus on the enlargement of biomass research spectrum, standardization of parameters and conversion of dimension etc. The research of biomass should hold the right orientation and technology to give scientific conclusion.
