根据Hutchinson的n维超体积概念以及物种与资源利用之间的关系,构建了青海云杉(Picea crassifolia)在三维环境资源空间中的生物-地理模型,并利用该模型模拟了青海云杉的潜在分布及其对环境资源的利用状况。结果表明:青海云杉在生长季平均气温、多年平均降水量及太阳直接辐射三维环境资源空间上的最佳配置为9℃、360mm和1.9×103kW·h·m–2;用三元方程式的拟合结果在大范围上预测了青海云杉的潜在分布区,并给出了其在对应地理位置上的生长状况。 According to Hutchinson’s concept of n-dimensional hypervolume and the relationship between species and resource utilization, a bio-geography model of Picea crassifolia in three-dimensional environmental resource space was constructed and used to simulate the potential of Picea crassifolia Distribution and Utilization of Environmental Resources. The results showed that the optimal configuration of Qinghai spruce (Picea crassifolia) in the growth season, the mean annual precipitation, the annual average precipitation and the spatial distribution of direct solar radiation was 9 ℃, 360mm and 1.9 × 103kW · h-2, respectively. The fitting result predicts the potential distribution area of ​​Picea crassifolia in a wide range and gives the corresponding growth position in the corresponding geographical position.
