项目摘要

This research has been conducted to establish the studies connecting water and energy cycles with material cycles and promote the studies on evaluations of environmental effect of forests. Concretely, it is to quantitatively analyze each cycle in the forests (small basin scale or meso-scale of 2〜20km), clear the relationship among the cycles of water, material and energy and establish an integrated SPAC model of water and energy cycles.In the Fukuoka Experimantal Forests of the Institute of Kyushu University Forests, we made the experimental study site to monitor water and energy cycles to conduct joint monitoring studies and carry out following subjects :(1) Quantitatively monitor the various factors related to water and energy cycles,(2) Establish the theoretical model based on the observation data and simulate and generalize the phenomena by the model,(3) Clarify the conversion system between water and energy cycles using the compatible factors such as evapotranspiration, latent heat and soil water,(4) Establish the integrated model of water and energy cycles in order to evaluate the environmental effect of forests.Although there remain some more problems to be solved in these subjects, we made an integrated model to simulate water and energy cycles. This model along with other sub-model based on the observation will be of use to evaluate the environmental effects of forests.

本研究的目的是建立水、能循环与物质循环的联系，促进森林环境效应评价的研究。具体地说，就是对森林中的各个循环进行定量分析（小流域尺度或2 × 20km的中尺度），明确水、物质、能量循环之间的关系，建立水、能量循环的SPAC综合模型。我们做了监测水和能源循环的实验研究现场，进行联合监测研究，并开展以下主题：（1）定量监测与水和能量循环有关的各种因素，（2）根据观测资料建立理论模型，并利用模型对现象进行模拟和概括。（3）利用蒸散、潜热和土壤水等相容因子，阐明水能循环之间的转换系统，（4）为评价森林的环境效应，建立了水循环和能量循环的综合模型，虽然在这方面还有许多问题需要解决，但我们还是建立了一个水循环和能量循环的综合模型。该模型沿着其它基于观测的子模型将可用于森林环境效应的评价。
